A comparison between Chevron and Mitchell osteotomies for hallux valgus
Foot & Ankle
|March 1, 1984
Summary
The Mitchell and Chevron osteotomies offer similar outcomes for hallux valgus correction. While the Mitchell procedure better corrects metatarsal angles, neither surgical technique demonstrated clinical superiority or improved patient satisfaction.
Area of Science:
- Orthopedic Surgery
- Podiatric Medicine
Background:
- Hallux valgus is a common foot deformity.
- Surgical correction aims to improve foot function and aesthetics.
Purpose of the Study:
- To compare the efficacy of Mitchell and Chevron osteotomies for hallux valgus correction.
- To evaluate patient satisfaction, clinical outcomes, and radiographic measurements.
Main Methods:
- Retrospective study of 15 Mitchell and 15 Chevron osteotomies.
- Follow-up periods: 21 ± 5 months (Chevron) and 34 ± 8 months (Mitchell).
- Evaluation included patient satisfaction, clinical findings, and radiographic measurements.
Main Results:
- Mitchell osteotomy showed better correction of the first-second metatarsal angle (2.3 vs 5.5 degrees).
- Chevron osteotomy demonstrated a tendency for immediate postoperative correction loss.
- No significant difference in clinical superiority or patient satisfaction between the two techniques.
Conclusions:
- Mitchell and Chevron osteotomies yield essentially equivalent results for hallux valgus.
- Despite satisfactory outcomes, metatarsalgia in lateral rays affects nearly 40% of patients.
- Careful consideration of foot load distribution is crucial in surgical planning.
