Introduction: The aim of this study was to analyze the radiological results of a roof (Chevron) osteotomy with a minimally invasive surgery technique of the first metatarsal in a uniform population of patients with moderate hallux valgus. Methods: Between October 2013 and November 2014, the hallux valgus was treated with a roof (Chevron) osteotomy using a minimally invasive technique of the first metatarsal in 24 feet of 21patients. All had a diagnosis of moderate hallux valgus. Results: The mean preoperative intermetatarsal angle between M1 and M2 was 12.46° (range: 11-15°, SD 1.03). Postoperatively, the mean intermetatarsal angle was 8.13° (range: 5-10°; SD 1.16), with an average angular correction of 4.33°. The mean hallux valgus angle was 33.96° (range: 20-40°; SD 4.93) before surgery and the average postoperative metatarsal-phalangeal angle was 8.16° (range: 3-15°, SD 2.86), thus improving an average of 25.86°. Conclusions: Radiological results with the minimally invasive technique (Chevron osteotomy) confirm that this procedure is safe and effective for the treatment of moderate hallux valgus, with mid-term satisfactory angular correction. This method reliably mimics the open Chevron surgical technique retaining all its known benefits. To our knowledge, no equivalent study was found in the literature.
