Abstrakt: Background and Objective: Through percutaneous approaches, hallux valgus corrections can be performed with minimal soft tissue injury, less postoperative pain and good cosmetic results. Bosch osteotomy and MICA (Minimally Invasive Chevron Akin) have shown to be effective techniques for the correction of hallux valgus, although there are currently no publications comparing each other. The aim of this study is to compare the radiological and functional results of both techniques.
Materials and Methods: A retrospective, comparative study was carried out on patients with moderate hallux valgus. They were divided into two groups according to the percutaneous technique performed: Chevron osteotomy and Bosch osteotomy with screw fixation. The metatarsophalangeal, intermetatarsal, and distal articular veneer declination angles of the first metatarsal and the bone consolidation time were evaluated radiologically. The American Orthopaedic Foot and Ankle Surgery (AOFAS) score was used for functional assessment. Complications were registered during the first year.
Results: Thirty-eight patients in each group were included for the study. In each of the groups, the radiological angles were compared preoperatively and at final follow-up, showing statistically significant changes in the three variables considered; but no differences were obtained by comparing them with each other. The time of consolidation was also similar in both groups. As for the AOFAS scale, an improvement was obtained with both techniques, but the difference was not significant when comparing them.
Conclusions: Both Bosch and MICA techniques showed comparable results at the end of the follow-up. Further work is needed to determine the advantages of each in the immediate postoperative time.
