Summary
Distal chevron fifth metatarsal osteotomy effectively treats painful bunionette, significantly improving forefoot scores and angles. This surgical procedure offers good outcomes with minimal complications in long-term follow-up.
Area of Science:
- Orthopedic Surgery
- Podiatric Medicine
- Foot and Ankle Surgery
Background:
- Bunionette, or tailor's bunion, is a common foot deformity causing pain.
- Surgical correction is often necessary for symptomatic cases.
- Distal chevron osteotomy is a technique used for correction.
Purpose of the Study:
- To evaluate the effectiveness of distal chevron fifth metatarsal osteotomy.
- To assess long-term outcomes and complications of this procedure for bunionette.
Main Methods:
- Nineteen distal chevron metatarsal osteotomies were performed on 13 patients.
- Follow-up averaged 7.1 years.
- Forefoot scores, intermetatarsal angles, and forefoot width were measured.
Main Results:
- Mean forefoot score improved significantly from 35.8 to 73.9 (out of 75).
- Intermetatarsal 4-5 angle, metatarsophalangeal 5 angle, and forefoot width showed significant improvement.
- Good results were observed in 17 feet, fair in 2; no failures occurred.
Conclusions:
- Distal chevron fifth metatarsal osteotomy is an effective treatment for symptomatic bunionette.
- The procedure yields significant functional and radiographic improvements.
- Complications, including transfer metatarsalgia and wound infection, were infrequent.
