FRCS Prep: Mastering Radial Head Fractures - Case Guide

Key Takeaway
We review everything you need to understand about FRCS Prep: Mastering Radial Head Fractures - Case Guide. Managing minimally displaced fractures of the radial head involves a complete history, examination, pain relief, and immobilization with a collar and cuff. Early movement and physiotherapy are crucial, with a 2-week follow-up. Surgical intervention for fractures of the radial is considered for complex elbow fracture dislocations where joint stability is compromised.
You are presented with a patient who has a highly comminuted, intra-articular radial head fracture. During surgery, you have performed a comprehensive arthroscopic assessment. Describe the technique for managing these comminuted fragments, and specifically, what is the role of arthroscopic-assisted fixation versus open reduction?

Candidate: I would evaluate the number of fragments and the degree of articular involvement. If reconstructible, I prefer ORIF using the Kocher interval. If the fracture is highly comminuted and non-reconstructible, particularly if there is an associated instability like a 'terrible triad' or Essex-Lopresti, I would proceed to radial head replacement. Arthroscopic assistance is useful for debridement or percutaneous pinning of smaller fragments.
Candidates often fail to discuss the 'Safe Zone' for hardware placement. They may suggest fixation for any fracture regardless of comminution, or fail to mention the absolute necessity of restoring radial length in the setting of longitudinal forearm instability (Essex-Lopresti).
A high-scoring answer structures the response by: 1. Classification: Utilizing the Mason-Johnston system. 2. Management Algorithm: Reconstruct if <3 fragments; replace if >3 fragments or non-reconstructible. 3. Surgical Technicality: Emphasize the 'Safe Zone' (posterolateral, 110-degree arc) to avoid hardware impingement. 4. Ligamentous Priority: Explicitly state that if longitudinal stability is compromised (Essex-Lopresti), radial head replacement is mandatory to restore length, regardless of the patient's age or activity level.
