Category: Bunion Introduction/Purpose: Hallux valgus deformity is recently a common disease involved in the foot and ankle and many procedures are recommended globally. However it is controversial about the operative treatment for severe hallux valgus. Many authors have reported the technical difficulties and various complications. We performed rotated insertion metatarsal osteotomy with the distal soft tissue procedure for severe hallux valgus deformity since January 2008. The purpose of this study is to evaluate the medium-term outcome of this procedure. Methods: Two hundred thirty-two feet in 173 patients were enrolled in this study and followed them up for a mean of 44.5 months. The mean age at the operation was 64.5 years. Hallux valgus angle(HVA) and intermetatarsal angle(IMA) were measured. This procedure consists of the rotated insertion metatarsal osteotomy and the distal soft tissue procedure. This diaphysial longitudinal metatarsal oblique osteotomy was performed from proximally- medial site of the first metatarsal directed to distally- lateral site through the dorsal exposure. The tip of osteotomized proximal metatarsal was formed at the dorso-distal site to insert in the central intramedullary aspect of osteotomized distal metatarsal. The second triangular cut of one third of dorso-plantar thick was made about 10 to 15 mm length from the lateral tip of osteomized proximal metatarsal. The internal fixation was performed with locking plate with screws. As a result, osteotomized sites were locked each other such as a puzzle. Results: The mean preoperative HVA and IMA were 43.8 degrees and 20.1 degrees. The mean postoperative HVA and IMA were decreased to 9.0 degrees and 6.1 degrees. AOFAS scores improved from 49.3 to 89.7. All cases were obtained complete union. Postoperative displacement was in 12 feet (5.2%) and followed under-correction (or recurrence). Overcorrection (hallux varus) occurred in 10 feet (4.7%). Wound healing was delayed in 21 feet (9.1%). In general, we found no severe complication and unsatisfactory result. Conclusion: This procedure provided satisfactory result for severe hallux valgus deformity. Especially the rigid fixation at the site of metatarsal osteotomy was much stronger because of the insertion and locking plate. However the further more outcomes in detail are essential for longer term follow-up.

Background/Aim. Despite bunion surgery having been performed for more than 100 years, there has yet to be a technique considered as the ?Gold Standard?. The aim of the study was to compare postoperative results of Mitchell vs. Golden methods of treating moderate hallux valgus deformity. Methods.This observational case control study included 49 patients (81 feet) who had the Mitchell distal metatarsal osteotomy performed, and 49 patients (77 feet) that had the Golden proximal metatarsal osteotomy performed. The results of treatment were evaluated using Hellal?s modification of the Bonney and McNab classification and the Hallux Metatarsophalangeal Interphalangeal Score (HMIS). The statistical analysis of the results was done, thus the values p < 0.05 were considered statistically significant. Results. Both operative procedures showed successful and statistically significant postoperative results compared to the preoperative status (p < 0.001). Comparative analysis of the results from the Mitchell and Golden procedures, according to the Hellal?s modification of Bonney and McNab classification, proved that there was a high statistically significant difference in favor of the Mitchell method (p < 0.001), whereas the comparison based on the HMIS showed no statistically significant difference (p = 0.123) between the two methods. The estimated results analysis of both procedures, based on the values of hallux valgus angle, intermetatarsal angle, sesamoid position, length of immobilization, treatment duration and complications demonstrated that there was a highly significant difference in favor of the Mitchell method (p < 0.001), whereas the value of the shortening of the first metatarsal bone indicated that the shortening was greater in the Mitchell method (p < 0.001), which goes in favor of the Golden method. Regarding the flexion of the thumb of the feet operated on, there was no statistically significant difference (p = 0.723). Conclusion. The examinations performed indicated that both methods showed good postoperative results, but applying the Mitchell method they were better.
