Abstract:
Objective To evaluated the result of modified Mitchell operation for treatment of hallux valgus. Methods From March 1998 to October 2001, 39 feet of 20 patients were treated with modified Mitchell procedure. Before operation, HVA averaged 29.5? and IMA averaged 12.5? were measured on standing AP radiographs. The lateral displacement of the capital fragment was depended on the amount of IMA and the capital fragment shifted plantarly 2-3 mm. Fixation was achieved with an absorbable screw. The lateral spike on the distal fragment was not preserved in this operation. Results After follow-up of 11-38 months, patients rated as excellent or good in 97.4%. The average postoperative HVA was 14.5? and IMA was 8.5?, the average HAV correction was 15? and 4? for the IMA. Conclusion The modified Mitchell procedure provides satisfactory deformity correction. The transverse arch of metatarsals is reconstructed since distal part of the first metatarsal is shifted plantarly in this operation.
