Summary
Scarf osteotomy effectively treats severe hallux valgus (bunion) deformity, significantly improving foot alignment and patient function. Midterm results show substantial correction of the hallux valgus angle and intermetatarsal angle, leading to better AOFAS scores.
Area of Science:
- Orthopedics
- Podiatry
- Surgical Innovation
Background:
- Hallux valgus, commonly known as a bunion, is a prevalent foot deformity.
- Severe cases often involve significant intermetatarsal (IM) angles, posing treatment challenges.
Purpose of the Study:
- To evaluate the midterm efficacy of scarf osteotomy for correcting severe hallux valgus deformity.
- To assess the radiographic and functional outcomes following this surgical procedure.
Main Methods:
- A retrospective review of 33 patients (45 feet) who underwent scarf osteotomy for hallux valgus with IM angle ≥ 16 degrees.
- Analysis of radiographic measurements (hallux valgus angle, IM 1-2 angle) and American Orthopedic Foot and Ankle Society (AOFAS) scores at an average follow-up of 26 months.
Main Results:
- Significant improvement in the hallux valgus angle (average 21.1 degrees correction).
- Significant improvement in the IM 1-2 angle (average 9.9 degrees correction).
- Substantial increase in AOFAS scores, from a preoperative average of 35.7 to 89.8 postoperatively.
Conclusions:
- Scarf osteotomy is an effective surgical technique for correcting severe hallux valgus deformity.
- The procedure yields significant radiographic and functional improvements at midterm follow-up.
- This method offers a viable solution for patients with challenging bunion deformities.
