| Summary: | Background
The aim of this study was to analyze the radiological results of a roof (“Chevron”) osteotomy with MIS (Minimally invasive surgery) technique of the first metatarsal in a uniform population of patients with moderate hallux valgus.
Methods
Surgical treatment of hallux valgus was performed between October 2013 and November 2014, by a roof ("Chevron") osteotomy with MIS technique of the first metatarsal in 24 feet of 21 patients. All patients had a diagnosis of moderate hallux valgus.
Results
The mean preoperative intermetatarsal angle between M1-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 angular correction of 4.33° in average. The mean preoperative hallux valgus angle was 33.96° (range: 20-40°; SD 4.93) and postoperatively, the metatarsal-phalangeal angle was 8.16° in average, (range: 3-15°, SD 2.86), thus improving in 25.86° in average.
Conclusions
Radiological results obtained from the minimally invasive technique (Chevron osteotomy), confirm a safe and effective procedure for the treatment of moderate hallux valgus, with mid-term satisfactory angular correction. This method faithfully mimics the open Chevron surgical technique retaining all its known virtues. To our knowledge, no equivalent study was found in the literature. |
