To evaluate the clinical and radiological results of a subcapital osteotomy of the first metatarsal using a percutaneous technique in the treatment of mild-to-moderate hallux valgus deformity.
We performed a retrospective study of 70 osteotomies using a modified B枚sch technique for the treatment of the painful hallux valgus, in 50 patients, all women, with an average follow-up of 7.5 years. We assessed the pre- and postoperative clinical outcome according to the American Orthopaedic Foot and Ankle Society (AOFAS) scale and radiological outcome by measuring the intermetatarsal (IMA) and the hallux valgus (HVA) angles.
According to the AOFAS scale, we obtained a global preoperative score of 42.09 and postoperative of 87.81 points. The postoperative radiological findings showed an average IMA of 7.3掳 and HVA of 13.7掳. There were two cases of deep infection satisfactorily treated with antibiotics and 3 cases of wire intolerance.
The percutaneous technique is a minimally invasive procedure has that is useful for the correct execution of a distal linear osteotomy of the first metatarsal for the correction of the painful hallux valgus. The clinical results appear to be comparable with those obtained by traditional open techniques, with substantially shorter operating times, and reduced risk of surgery-related complications.
