Summary
For hallux valgus surgery, releasing the lateral joint capsule and adductor hallucis tendon significantly corrects the hallux valgus angle. Disconnecting the transverse metatarsal ligament offers no additional benefit.
Area of Science:
- Orthopedic Surgery
- Foot and Ankle Anatomy
Context:
- Lateral release is a key part of distal soft tissue procedures for hallux valgus.
- The optimal extent of lateral release remains debated in surgical practice.
Purpose:
- To anatomically evaluate the impact of sequentially releasing lateral soft tissue structures on hallux valgus correction.
- To determine the contribution of specific structures (capsule, adductor hallucis tendon, transverse metatarsal ligament) to toe alignment.
Summary:
- Sequential release of lateral structures was performed on 8 anatomical specimens under lateral pull.
- Significant hallux valgus angle improvement was achieved by capsule splitting and adductor hallucis tenotomy.
- No significant correction of the intermetatarsal angle was observed.
Impact:
- Capsular splitting is the primary effective component of distal soft tissue procedures for hallux valgus.
- Transverse metatarsal ligament release does not contribute to further correction and can be omitted.
