Clinico-radiological Results of Distal Chevron Osteotomy without Lateral Soft Tissue Release in Mild to Moderate Hallux Valgus Deformity.

Abstract

The study was done to evaluate short term clinico-radiological results of distal chevron oste-otomy without lateral soft tissue release in mild to moderate hallux valgus. This was a prospective study consisting of a total of 35 cases with mild to moderate hallux valgus deformity. All these patients were treated by distal chevron osteotomy without lateral soft tissue release. In our study, the average value of hallux angle preoperatively was 32° (range, 24°-40°) and at final follow-up it was 14° (range, 8°-31°). The average reduction was 18°. The average intermetatarsal angle showed mean reduction of 5.3° at the final follow-up. Average range of motion of the first metatarsophalyngeal joint preoperatively and at final follow-up showed a small reduction of 5 degrees. The average preoperative AOFAS score was 49, which improved by 35 points to 84 at the final follow-up. 11.42% of the patients in the study group had a recurrence. 1. Based on our experience with distal chevron osteotomy without lateral soft tissue release, we found the procedure easy to perform with good procedural outcomes. 2. The possible complications of lateral soft tissue release are avoided.
