Dorsal Cheilectomy for Hallux Rigidus: An Intraoperative Masterclass

Introduction and Epidemiology

Hallux rigidus, a progressive degenerative arthrosis of the first metatarsophalangeal (MTP) joint, represents the second most common condition affecting the great toe, trailing only hallux valgus in prevalence. It is characterized by limited dorsiflexion of the first MTP joint dueostasis as a consequence of dorsal osteophyte impingement, leading to pain and functional impairment during activities requiring first MTP joint motion, such as ambulation and toe-off. While plantarflexion is typically preserved in early stages, significant restriction may occur with large dorsal osteophytes or advanced global arthrosis. The condition predominantly affects adults in their fifth and sixth decades, with a slight female predilection, though it can manifest earlier, particularly in cases with a congenital predisposition or post-traumatic etiology. Its incidence is estimated to be approximately 2.5% in individuals over 50 years of age, making it a significant contributor to forefoot morbidity.

Etiology and Pathogenesis of Hallux Rigidus

The pathogenesis of hallux rigidus is multifactorial, encompassing mechanical, genetic, and inflammatory components. Primary hallux rigidus often lacks a clear inciting event and is thought to be related to subtle biomechanical abnormalities, such as a long first metatarsal, an elevated first metatarsal, or an abnormally shaped first metatarsal head (e.g., dorsiflexed articular surface or metatarsus primus elevatus), which can lead to increased dorsal compressive forces during gait. Repetitive microtrauma and subsequent osteophyte formation at the dorsal aspect of the metatarsal head and proximal phalanx are hallmark features, progressively limiting dorsiflexion.
Secondary hallux rigidus can result from acute trauma (e.g., turf toe injury), inflammatory arthropathies (e.g., rheumatoid arthritis, gout), osteochondritis dissecans, infection, or iatrogenic causes following surgery. Congenital hallux rigidus is less common but tends to be bilateral and is often associated with concomitant hallux interphalangus, suggesting a developmental component. The early dorsal impingement of the proximal phalanx on the metatarsal head, aggravated by normal gait mechanics, initiates a cascade of cartilage degeneration, synovial inflammation, and osteophyte formation, culminating in the characteristic restricted motion.

Clinical Presentation and Staging

Patients typically present with pain localized to the dorsal aspect of the first MTP joint, exacerbated by walking, running, or wearing shoes with inadequate toe box height. Swelling, stiffness, and crepitus may also be reported. On physical examination, palpable dorsal osteophytes and tenderness are common. Assessment of first MTP joint motion is critical, particularly dorsiflexion, which is typically limited. Plantarflexion may also be restricted in advanced stages.

Various classification systems exist, with the Coughlin and Shurnas classification being widely utilized for guiding treatment decisions:
* Grade 0: Pre-hallux rigidus. Mild pain, minimal osteophyte, normal range of motion.
* Grade 1: Mild pain, minimal dorsal osteophyte, slight flattening of metatarsal head, dorsiflexion 30-40 degrees.
* Grade 2: Moderate pain, moderate dorsal osteophytes, joint space narrowing, dorsiflexion 10-30 degrees.
* Grade 3: Severe pain, large dorsal osteophytes, significant joint space narrowing, subchondral sclerosis, dorsiflexion <10 degrees.
* Grade 4: Pan-MTP joint arthrosis, severe pain, severe joint space narrowing, extensive osteophyte formation, complete loss of motion.
Radiographic evaluation includes weight-bearing anteroposterior, lateral, and oblique views to assess joint space narrowing, osteophyte size, subchondral sclerosis, and alignment.

Surgical Anatomy and Biomechanics

A thorough understanding of the first MTP joint anatomy and its intricate biomechanics is paramount for successful surgical intervention for hallux rigidus. The first MTP joint is a condyloid synovial joint formed by the convex head of the first metatarsal and the concave base of the proximal phalanx.

Osseous Structures and Articular Surfaces

The first metatarsal head is typically wider medially than laterally and possesses a smooth, spherical articular surface, though variations such as a flatter or dorsally angled surface can predispose to hallux rigidus. The base of the proximal phalanx has a corresponding articular facet. Within the plantar aspect of the metatarsal head, two longitudinal grooves accommodate the sesamoid bones, which articulate with the metatarsal head, forming a critical sesamoid-metatarsal articulation. These sesamoids act as a fulcrum for the flexor hallucis brevis (FHB) muscle, increasing its mechanical advantage.

Ligamentous and Capsular Stabilizers

The first MTP joint is supported medially and laterally by strong collateral ligaments, which originate from the sides of the metatarsal head and insert into the base of the proximal phalanx. These ligaments provide crucial medial-lateral stability.

FIG 1 • A. Medial aspect of first MTP joint anatomy. Collateral ligaments afford medial-lateral stability.
Dorsally, the joint capsule is relatively thin and reinforced by the extensor hallucis longus (EHL) tendon and extensor hood. Plantarly, the joint is reinforced by the thick, fibrocartilaginous plantar plate, which originates from the metatarsal neck and inserts into the base of the proximal phalanx. The plantar plate provides significant vertical stability and acts as a dynamic stabilizer.

The Sesamoid Complex and Associated Tendons

The plantar aspect of the joint is characterized by the sesamoid complex, which consists of two small, oval sesamoid bones (medial and lateral) embedded within the FHB tendons. The two slips of the FHB muscle invest the sesamoids, with the medial slip typically incorporating the medial sesamoid and the lateral slip incorporating the lateral sesamoid.

FIG 1 • B. Dorsal aspect of first MTP joint anatomy. C. Detail of first MTP joint anatomy with detail of sesamoid complex.
The flexor hallucis longus (FHL) tendon traverses between the two sesamoids within the sesamoid groove on the plantar aspect of the metatarsal head. The FHL provides powerful plantarflexion of the hallux and contributes to overall forefoot stability during gait. The FHB and FHL together play a critical role in weight-bearing and propulsion, with the sesamoids protecting the FHL tendon and improving the biomechanical lever arm of the FHB.

Dorsal Aspect Musculature and Innervation

The dorsal aspect of the joint includes the joint capsule, the attachment of the extensor hallucis brevis (EHB) to the base of the proximal phalanx, and the EHL tendon within the extensor hood. The EHL is the primary dorsiflexor of the hallux.
The cutaneous innervation of the dorsal first MTP joint region is primarily from the medial dorsal cutaneous nerve (a branch of the superficial fibular nerve) and the medial plantar nerve (a branch of the tibial nerve). The saphenous nerve provides sensation to the medial aspect of the foot, potentially contributing to the surgical field. Careful identification and protection of these neurovascular structures are essential during a dorsal approach to prevent iatrogenic injury.

Biomechanics of First MTP Joint Function

Normal gait requires approximately 60-70 degrees of dorsiflexion at the first MTP joint during the toe-off phase. The sesamoid complex articulates with the metatarsal head, functioning as an anatomical pulley system, which significantly enhances the mechanical efficiency of the FHB and FHL tendons. In hallux rigidus, the formation of dorsal osteophytes on the metatarsal head and proximal phalanx mechanically blocks dorsiflexion, leading to impingement and pain. This impingement occurs at approximately 15-20 degrees of dorsiflexion in early stages, progressively worsening. The restricted motion alters the biomechanics of the entire foot, often leading to compensatory pronation, transfer metatarsalgia, and altered gait patterns. The concept of "functional hallux limitus" describes a condition where dorsiflexion is restricted only under weight-bearing conditions, suggesting dynamic instability or malalignment contributing to the impingement phenomenon. Understanding these intricate relationships is crucial for precise surgical planning and execution of procedures like cheilectomy, which aim to restore functional dorsiflexion by removing the osseous obstruction.

Indications and Contraindications

Cheilectomy for hallux rigidus is primarily indicated for patients with early to moderate stages of the disease, aiming to alleviate pain and restore functional dorsiflexion by removing the dorsal osteophytic impingement. Careful patient selection is critical for optimizing outcomes.

Non Operative Management Strategies

Initial management of hallux rigidus is typically conservative, particularly for Grade 0 to Grade 2 disease. These strategies focus on pain reduction and optimizing joint mechanics.
* Footwear Modification: Shoes with a stiff sole, rocker bottom design, or a wide, deep toe box can reduce motion at the first MTP joint and minimize dorsal impingement.
* Orthotics: Custom or off-the-shelf orthoses may be prescribed to provide support, reduce pronation, and improve alignment. A Morton's extension can be used to redistribute forces.
* Activity Modification: Avoiding activities that exacerbate pain, such as running, jumping, or prolonged standing on uneven surfaces.
* Pharmacotherapy: Non-steroidal anti-inflammatory drugs (NSAIDs) can help manage pain and inflammation.
* Injections: Corticosteroid injections into the joint may provide temporary pain relief, particularly in cases with an inflammatory component, but their long-term efficacy is limited, and repeated injections carry risks of cartilage damage.
* Physical Therapy: Exercises to maintain or improve existing range of motion, strengthen intrinsic foot muscles, and improve gait mechanics.

Operative Indications for Cheilectomy

Cheilectomy is considered when non-operative measures fail to provide adequate pain relief and functional improvement. It is most effective for Grade 1 and Grade 2 hallux rigidus, where significant joint space narrowing is absent, and the primary pathology is dorsal osteophyte impingement.
* Persistent pain: Unrelieved by at least 3-6 months of comprehensive non-operative management.
* Dorsal impingement: Clinical and radiographic evidence of significant dorsal osteophytes mechanically blocking dorsiflexion.
* Preserved joint space: Minimal to moderate joint space narrowing on weight-bearing radiographs.
* Good quality articular cartilage: Intact or minimally degenerated cartilage on the central and plantar aspects of the metatarsal head and proximal phalanx.
* Adequate passive range of motion: Ability to achieve at least 50% of normal dorsiflexion passively once the dorsal osteophyte block is overcome (e.g., using a "push-off" test).
* Patient expectation: Realistic expectations regarding pain relief and functional improvement.

Contraindications for Cheilectomy

While cheilectomy is a reliable procedure for appropriate cases, several factors constitute relative or absolute contraindications:
* Advanced Hallux Rigidus (Grade 3-4): Significant global arthrosis, severe joint space narrowing, extensive subchondral sclerosis, or cyst formation throughout the joint. In these stages, cheilectomy alone is unlikely to provide adequate relief, and alternative procedures like arthrodesis or arthroplasty are typically more appropriate.
* Severe MTP Instability: Ligamentous laxity or significant instability of the first MTP joint.
* Active Infection: Absolute contraindication to elective surgery.
* Poor Vascularity or Neuropathy: Compromised peripheral circulation or severe diabetic neuropathy increases surgical risks and impairs healing.
* Uncontrolled Inflammatory Arthropathy: Systemic conditions like rheumatoid arthritis or psoriatic arthritis should be adequately managed medically before considering surgery.
* Unrealistic Patient Expectations: Patients expecting complete restoration of pain-free, full range of motion may be disappointed.
* Lack of Patient Compliance: Inability or unwillingness to comply with postoperative rehabilitation protocols.

Pre Operative Planning and Patient Positioning

Thorough preoperative planning is crucial to ensure patient safety, optimize surgical outcomes, and anticipate potential challenges. This involves a detailed clinical assessment, comprehensive radiographic evaluation, and meticulous surgical setup.

Clinical Assessment and Evaluation

A comprehensive history should include the duration and character of pain, aggravating and alleviating factors, previous treatments, and the patient's functional limitations. Special attention should be given to activity levels, footwear preferences, and vocational demands.
Physical examination focuses on the first MTP joint. Inspect for swelling, erythema, and the presence of dorsal exostoses. Palpate the joint line for tenderness, particularly dorsally. Assess passive and active range of motion (ROM) of the first MTP joint, noting the degree of dorsiflexion and plantarflexion. Crucially, assess the "push-off" test or forced dorsiflexion test to determine if the limitation is purely mechanical due to osteophyte impingement or if global arthrosis is present. With the foot pronated to unlock the midfoot, a significant increase in dorsiflexion after overcoming the dorsal block suggests intact central cartilage and suitability for cheilectomy. Also, evaluate the stability of the joint, alignment of the hallux, and the presence of any concomitant deformities such as hallux valgus or metatarsus primus elevatus. Neurovascular status of the foot should be thoroughly documented.

Radiographic Imaging Protocol

Standard weight-bearing radiographs are essential for assessing the severity of hallux rigidus and guiding surgical planning.
* Weight-bearing Anteroposterior (AP) View: Evaluates joint space narrowing, metatarsophalangeal angle, hallux interphalangeal angle, and identifies medial and lateral osteophytes.
* Weight-bearing Lateral View: Crucial for assessing the size and location of dorsal osteophytes, degree of joint space narrowing, and presence of metatarsus primus elevatus. This view best demonstrates the extent of dorsal impingement.
* Oblique View: Helps visualize the articular surface and presence of osteophytes that may be obscured on other views.
The Coughlin and Shurnas classification system (Grades 0-4) provides a framework for interpreting radiographic findings and correlating them with clinical severity. Advanced imaging such as CT or MRI is generally not required for routine cheilectomy unless there is suspicion of other pathologies (e.g., osteochondral lesions, stress fractures, or soft tissue masses) or for detailed preoperative planning in complex cases.

Anesthesia and Patient Positioning

• Anesthesia: A regional ankle block (typically a combination of deep peroneal, superficial fibular, saphenous, sural, and posterior tibial nerves) with sedation is often preferred due to its excellent postoperative analgesia. General anesthesia is an alternative, especially if the patient prefers it or if a more extensive procedure is anticipated.
• Patient Positioning: The patient is positioned supine on the operating table.
• Tourniquet: A thigh or ankle tourniquet is applied to provide a bloodless field, which is critical for precise dissection and osteophyte resection.
• Sterile Prep and Drape: The entire foot and ankle are prepped with an antiseptic solution and draped in a sterile fashion, ensuring adequate exposure of the first MTP joint while maintaining sterility. A sterile stockinette is often used to isolate the foot. The ipsilateral hip may be externally rotated slightly to facilitate dorsal access to the MTP joint.

Detailed Surgical Approach and Technique

Cheilectomy involves the removal of dorsal and dorsomedial osteophytes from the first metatarsal head and, if present, from the base of the proximal phalanx, with the primary goal of increasing dorsiflexion and relieving pain. The specific technique can be adapted based on surgeon preference and the extent of the osteophytes.

Incision and Dissection

The procedure is typically performed under tourniquet control.
* Incision: A dorsal longitudinal incision, approximately 4-6 cm in length, centered over the first MTP joint and extending distally onto the proximal phalanx and proximally onto the first metatarsal shaft. Alternatively, a dorsomedial incision can be used, following the course of the EHL tendon to improve exposure of the medial joint capsule. The dorsomedial approach is generally preferred as it is less likely to injure the medial dorsal cutaneous nerve and provides better access to the medial aspect of the joint and the medial collateral ligament.

* Superficial Dissection: The incision is carried through the skin and subcutaneous tissue. Meticulous care must be taken to identify and protect the branches of the medial dorsal cutaneous nerve and the superficial veins. The medial dorsal cutaneous nerve typically lies dorsomedially to the EHL tendon.
* Deep Dissection: The extensor hallucis longus (EHL) tendon sheath is identified. The EHL tendon is carefully retracted either medially or laterally, usually laterally for a better view of the medial aspect of the joint. The dorsal joint capsule is then exposed.

Capsulotomy and Joint Exposure

• Capsulotomy: A longitudinal capsulotomy is performed directly over the dorsal aspect of the metatarsal head, extending distally onto the proximal phalanx. Some surgeons prefer an inverted 'L' or 'T' capsulotomy to allow for broader exposure and later capsule repair. The capsulotomy allows visualization of the dorsal osteophytes and the articular cartilage.

Dorsal Osteophyte Resection Cheilectomy

• Identification of Osteophytes: Dorsal osteophytes on both the first metatarsal head and the base of the proximal phalanx are clearly identified. The critical osteophyte is typically located on the dorsal aspect of the metatarsal head, mechanically blocking dorsiflexion.
• Resection Technique: Using a small osteotome, a sagittal saw, or a high-speed burr, the dorsal osteophyte is carefully resected. The resection should extend proximally along the metatarsal neck to ensure adequate bone removal. Approximately 20-30% of the dorsal metatarsal head should be resected to achieve sufficient dorsiflexion clearance, typically 5-7 mm of bone.
  • Metatarsal Head: The resection should be flush with the articular cartilage of the metatarsal head, avoiding damage to the healthy cartilage. It's crucial to remove enough bone to eliminate impingement without destabilizing the joint. The goal is to create a "shelf" that allows the base of the proximal phalanx to dorsiflex without impinging.
  • Proximal Phalanx: Any osteophytes present on the dorsal base of the proximal phalanx should also be excised.

• Assessment of Dorsiflexion: After initial osteophyte resection, the first MTP joint is manually dorsiflexed to assess the improvement in range of motion. The goal is to achieve at least 70-90 degrees of pain-free passive dorsiflexion. If impingement persists, further bone removal may be necessary, extending slightly more proximally or laterally on the metatarsal head.

Addressing Lateral Osteophytes and Synovectomy

• Lateral Osteophytes: If present, lateral osteophytes on the metatarsal head can also cause impingement and should be resected. This may require additional soft tissue dissection laterally or slight repositioning of the EHL tendon.
• Synovectomy: Any inflamed or hypertrophic synovium within the joint should be debrided, particularly dorsally, to reduce postoperative inflammation and pain.
• Chondroplasty: If chondral lesions are identified, particularly on the dorsal articular surface, debridement or microfracture may be considered, though this is not a primary component of cheilectomy.

Optional Concomitant Procedures

In some cases, cheilectomy may be combined with other procedures to address related deformities or improve outcomes.
* Moberg Osteotomy (Proximal Phalanx Dorsiflexion Osteotomy): This is a dorsal closing wedge osteotomy of the proximal phalanx, which tilts the articular surface dorsally. It can be performed in conjunction with cheilectomy to further improve dorsiflexion in patients with more advanced joint space narrowing or insufficient dorsiflexion post-cheilectomy. It effectively moves the articulation more proximally on the metatarsal head, providing more cartilage contact area during dorsiflexion.

* Hallux Valgus Correction: If a concomitant mild hallux valgus deformity is present, a distal metatarsal osteotomy (e.g., Chevron or Weil) may be considered, though careful assessment of potential impact on first MTP joint mechanics is necessary.

Closure

• Capsule Closure: The joint capsule is typically closed with absorbable sutures. Careful closure helps restore joint stability and minimize synovial herniation.
• Subcutaneous Layer: The subcutaneous tissues are reapproximated with absorbable sutures.
• Skin Closure: The skin is closed with non-absorbable sutures or staples.
• Dressing: A sterile, soft dressing is applied, often incorporating a compressive wrap and a splint or surgical shoe to protect the repair and maintain the neutral position of the hallux. The tourniquet is then deflated.

Complications and Management

While cheilectomy is generally considered a safe and effective procedure, like any surgical intervention, it carries potential risks and complications. Understanding these complications, their incidence, and appropriate management strategies is crucial for orthopedic surgeons.

Intraoperative Complications

• Neurovascular Injury: Injury to the medial dorsal cutaneous nerve (a branch of the superficial fibular nerve) is the most common iatrogenic nerve injury due to its proximity to the dorsal incision. This can result in permanent numbness or painful neuroma. Prevention involves careful blunt dissection, clear identification, and retraction of nerve branches.
• Articular Cartilage Damage: Accidental damage to the healthy articular cartilage of the metatarsal head or proximal phalanx during osteophyte resection, particularly with power tools, can lead to accelerated arthrosis. Prevention requires meticulous technique and precise bone removal.
• Inadequate Resection: Insufficient removal of dorsal osteophytes can result in persistent impingement and continued limited dorsiflexion, leading to ongoing pain and patient dissatisfaction. This often necessitates revision surgery.
• Over Resection: Excessive removal of the metatarsal head can lead to instability of the first MTP joint, joint stiffness, or avascular necrosis, although this is rare.

Postoperative Complications

• Infection: Superficial wound infection or, less commonly, deep joint infection. Incidence is low but requires prompt antibiotic treatment and potentially surgical debridement.
• Persistent Pain/Stiffness: This is the most common reason for patient dissatisfaction. It can result from inadequate osteophyte removal, progression of underlying arthrosis, formation of new osteophytes, or scar tissue formation within the joint.
• Recurrence of Osteophytes: Over time, particularly if the underlying biomechanical factors are not addressed or if significant subchondral bone was left exposed, new dorsal osteophytes can form, leading to a recurrence of symptoms.
• Complex Regional Pain Syndrome CRPS: A rare but debilitating complication characterized by disproportionate pain, swelling, and autonomic dysfunction. Early diagnosis and aggressive multimodal treatment are crucial.
• Metatarsalgia/Transfer Metatarsalgia: Altered weight-bearing patterns after first MTP joint surgery can lead to increased pressure under the lesser metatarsal heads, causing pain. This can be exacerbated if the first ray is shortened or elevated.
• Hallux Hammertoe or MTP Joint Instability: Although rare, aggressive capsular resection or over-resection of bone can lead to hallux deformities or instability.
• Scar Sensitivity/Adhesions: Scar tissue can be sensitive or restrict tendon gliding, leading to discomfort or limited motion.

Post Operative Rehabilitation Protocols

A structured and progressive postoperative rehabilitation protocol is vital after cheilectomy to facilitate healing, restore range of motion, minimize stiffness, and optimize functional recovery. The specific timeline and emphasis may vary based on the extent of surgery and individual patient factors, but the general principles remain consistent.

Immediate Postoperative Period (Days 0-14)

• Weight Bearing: Patients are typically permitted immediate weight-bearing in a stiff-soled surgical shoe, or post-operative boot, for the first 2-4 weeks. Crutches may be used for balance and comfort, especially in the first few days.
• Pain Management: Oral analgesics, including NSAIDs (if not contraindicated) and acetaminophen, are prescribed. Regional anesthesia (ankle block) can provide excellent initial pain control.
• Edema Control: Elevation of the foot, ice application, and compression dressings are encouraged to minimize swelling.
• Wound Care: The dressing is typically changed by the surgeon or nursing staff within 2-7 days. Meticulous wound care is essential until sutures are removed, usually at 10-14 days. Patients are instructed to keep the incision dry.
• Early Range of Motion: Gentle active and passive range of motion exercises for the first MTP joint are initiated as tolerated, often starting within 24-48 hours post-surgery. The focus is on encouraging plantarflexion and gentle dorsiflexion within the limits of pain. Manual self-mobilization by the patient, as demonstrated by the surgeon or therapist, is beneficial.

Early Mobilization and Strengthening (Weeks 2-6)

• Removal of Sutures/Staples: Typically at 10-14 days.
• Transition to Regular Footwear: Once swelling subsides and wound healing is satisfactory, patients can transition from the surgical shoe to a wide, comfortable, supportive shoe with a stiff sole or rocker bottom. High heels or shoes with narrow toe boxes should be avoided.
• Physical Therapy Referral: Formal physical therapy is often initiated at this stage, focusing on:
  • Continued Range of Motion: Aggressive but controlled range of motion exercises, especially dorsiflexion, to prevent stiffness. Manual mobilization techniques by the therapist can be beneficial.
  • Strengthening: Gradual strengthening of intrinsic foot muscles, and extrinsic muscles (e.g., toe curls, towel scrunches).
  • Gait Training: Re-education on normal gait mechanics, particularly the toe-off phase, to avoid compensatory patterns.
• Modalities: Therapeutic modalities such as ultrasound, electrical stimulation, or cold compression may be used to manage pain and swelling.

Progressive Strengthening and Return to Activity (Weeks 6-12 and Beyond)

• Advanced Strengthening: Progress to more demanding strengthening exercises for the foot and ankle, including calf raises, balance exercises, and proprioceptive training.
• Activity Progression: Gradual return to low-impact activities, such as cycling or swimming, typically by 6-8 weeks. Running and jumping activities are introduced incrementally, usually after 10-12 weeks, provided pain-free range of motion has been achieved and strength has significantly recovered.
• Sport-Specific Training: For athletes, sport-specific drills are incorporated to prepare for full return to play, typically at 3-6 months, depending on the sport and individual progress.
• Long-Term Considerations: Patients are advised on continued footwear selection, orthotic use (if indicated), and maintenance exercises to prevent recurrence of stiffness or symptoms. Full recovery and maximum improvement in range of motion and pain relief can continue for up to 6-12 months post-surgery. Regular follow-up with the surgeon is essential to monitor progress and address any concerns.

Summary of Key Literature and Guidelines

Cheilectomy has a long and established history as a foundational surgical treatment for early and moderate stages of hallux rigidus. The literature consistently supports its efficacy in reducing pain and improving function in carefully selected patients.

Landmark Studies and Efficacy

Early descriptions of osteophyte excision for hallux rigidus date back to the early 20th century. McKeever (1952) is often credited with popularizing the modern cheilectomy, demonstrating favorable results in a large series of patients. Subsequent studies have largely validated its role.
* Retrospective Series: Numerous retrospective studies have reported good to excellent results with cheilectomy, with patient satisfaction rates typically ranging from 70% to 90%. Pain relief is a consistent finding, and functional improvements are observed in activities of daily living.
* Long-term Outcomes: Long-term follow-up studies, some extending beyond 10 years, indicate that the benefits of cheilectomy are durable in a significant proportion of patients. However, a subset of patients may experience symptom recurrence or progression of arthrosis, sometimes requiring further intervention. Van Gils et al. (2014) published a systematic review highlighting the overall positive outcomes but also identified varying success rates based on radiographic staging.
* Comparison with Other Procedures: Cheilectomy is often compared to other joint-sparing procedures like the Moberg osteotomy or various metatarsal osteotomies (e.g., dorsal closing wedge osteotomy of the metatarsal) for hallux rigidus. While cheilectomy primarily addresses dorsal impingement, Moberg osteotomy aims to increase functional dorsiflexion by changing the orientation of the proximal phalanx articular surface. Studies suggest that combining cheilectomy with a Moberg osteotomy may yield superior results in terms of dorsiflexion and patient satisfaction, especially in Grade 2-3 cases where cheilectomy alone may be insufficient. Roukis (2009) emphasized the role of combined procedures for optimal outcomes.

Current Consensus and Guidelines

• Indications: Current guidelines strongly recommend cheilectomy for Grade 1 and Grade 2 hallux rigidus. For Grade 3 disease, cheilectomy may be considered, often in conjunction with a Moberg osteotomy, provided the central articular cartilage remains relatively well-preserved. For Grade 4 disease, where global arthrosis is predominant, arthrodesis (fusion) remains the gold standard, offering reliable pain relief and stability, albeit at the cost of motion. Arthroplasty options (interpositional arthroplasty, implant arthroplasty) are also available but carry different sets of risks and long-term considerations.
• Role of Arthroscopy: Arthroscopic cheilectomy is a minimally invasive alternative that has gained traction. While it offers potential benefits such as smaller incisions, reduced soft tissue dissection, and possibly faster recovery, it requires specific technical expertise and has a steeper learning curve. Outcomes appear comparable to open cheilectomy in selected cases, particularly for milder disease.
• Patient Selection: Emphasis is placed on meticulous patient selection. Key factors include the extent of articular cartilage degeneration, the primary location of pain and mechanical block (dorsal impingement vs. global arthrosis), and patient expectations.
• Postoperative Management: Early mobilization and structured physical therapy are universally recommended across guidelines to maximize functional recovery and prevent stiffness.

Future Directions

Research continues to explore advanced imaging techniques for earlier diagnosis and more precise grading of cartilage damage. Biologic adjuncts, such as platelet-rich plasma (PRP) or mesenchymal stem cells, are being investigated for their potential to enhance cartilage repair or regeneration following cheilectomy, though their role remains experimental and unproven in routine clinical practice for hallux rigidus. The ongoing development of less invasive surgical techniques and refined rehabilitation protocols aims to further improve patient outcomes and minimize recovery times for this prevalent and often debilitating condition. Cheilectomy remains a cornerstone of surgical management for appropriate stages of hallux rigidus, representing a joint-preserving procedure that provides significant clinical benefit.
