Background: The purpose of this study was to observe short term results of distal chevron osteotomy in mild to moderate hallux valgus deformity with respect to deformity correction, radiographic and functional outcomes and record of complications. Methods: The study was a prospective study and consisted of a total of 35 cases who were admitted in the Bone and Joint Surgery Hospital from September 2017 to March 2020. All the patients were treated by distal chevron osteotomy. Results: In our study, the average value of hallux angle preoperative was 32° (range, 24°-40°) and at final followup it was 14° (range, 8°-31°). The average reduction was 18°. The average intermetatarsal angle showed mean reduction of 2.7° at the final follow-up. Average range of motion of the first metatarsophalyngeal joint preoperative and at final follow-up showed small reduction of 5 degrees. The average preoperative AOFAS score was 49, which improved by 35 points to 84 at the final follow-up.  11.4% of the patients in the study group recurrence. Conclusions: Based on our experience with distal chevron osteotomy, we found the procedure easy to perform with good procedural outcomes. However, the patient or the parents should be counselled before the procedure of possible complications, particularly recurrence.
