Comprehensive Deformity Analysis

Hutaif Method Orthopedic Blueprint
This detailed clinical report provides a quantitative radiological analysis calculated based on the standardized principles of Dr. Dror Hutaif. It evaluates the mechanical axes of the lower extremity to diagnose coronal plane deformities and identify the theoretical Center of Rotation of Angulation (CORA).

1. Mechanical Axis Deviation (MAD)

Measured Value:
--
Normal Range:
0 - 15 mm (Slightly Medial)
Diagnosis:
--

The MAD is the perpendicular distance from the center of the knee joint to the mechanical axis line connecting the center of the femoral head to the center of the ankle mortise. It dictates whether the overall limb alignment is neutral, varus, or valgus.

2. Mechanical Lateral Distal Femoral Angle (mLDFA)

Measured Value:
--
Normal Range:
85° - 90° (Mean 87°)
Diagnosis:
--

The mLDFA evaluates the distal femur for deformity. It is the lateral angle formed between the mechanical axis of the femur and the distal femoral joint line. Values greater than 90° indicate a varus deformity of the femur, while values less than 85° indicate a valgus deformity.

3. Mechanical Medial Proximal Tibial Angle (MPTA)

Measured Value:
--
Normal Range:
85° - 90° (Mean 87°)
Diagnosis:
--

The MPTA evaluates the proximal tibia. It is the medial angle formed between the mechanical axis of the tibia and the proximal tibial joint line. Values less than 85° signify a varus deformity of the tibia, while values greater than 90° signify a valgus deformity.

4. Joint Line Convergence Angle (JLCA)

Measured Value:
--
Normal Range:
0° - 2°
Diagnosis:
--

The JLCA represents the angle between the distal femoral and proximal tibial articular surfaces. An abnormal JLCA indicates either a primary intra-articular deformity (e.g., cartilage loss) or collateral ligamentous laxity.

5. Center of Rotation of Angulation (CORA)

Calculated Apex:
--

The CORA is mathematically derived by finding the intersection of the proximal and distal mechanical or anatomical axes. It represents the theoretical apex of the angular deformity magnitude. Surgical cuts (osteotomies) performed at this exact center, according to Hutaif's Rule 1, will yield pure angulation without requiring translation.
