| Popis: | Category: Bunion Introduction/Purpose: Minimally Invasive Chevron Akin (MICA) can be used to treat hallux valgus (HV) associated with a hypermobility of the first metatarsal-cuneiform joint (1MTCJ). The aim of this study was to perform a radiographic analysis of the MICA, focused on evaluating the 1MTCJ. Methods: Forty patients (50 feet) with moderate to severe HV underwent a MICA procedure. Radiographic analysis included hallux valgus angle (HVA), intermetatarsal angles between the first and second rays (IMA), the intermetatarsal angle between the proximal fragment of the osteotomy and the second ray (IAPF) and the distance between a point 3 cm distal from the base of the second metatarsal and a point located at the same height for the first metatarsal base (Dist 1-2). The IAPF was compared with the preoperative IMA and the other parameters were compared pre and post-operatively. The radiographic complications were also recorded Results: The majority of patients were female (92%). The mean age was 50.4 years (SD =16.1) and the mean follow-up was 16.1 months (SD = 3.5). The average HVA improved from 32.5 to 7.3 degrees and the average IMA from 14.2 to 4.2 degrees. The IAPF and Dist1-2 values showed an increase of 4.8 and 3.2mm respectively. There were no radiographic complications Conclusion: Minimally Invasive Chevron Akin: Locking the Metatarsal-Cuneiform Joint. |
