Abstract

Double osteotomy of the first metatarsal is an option in treatment of severe hallux valgus deformity. Good short-term results have been reported with percutaneous surgery in hallux valgus with moderate deformity. We report short-term results with percutaneous double osteotomy of the first metatarsal in severe deformities. This is a prospective study of 6 patients with severe hallux valgus deformity who were treated with percutaneous double osteotomy of the first metatarsal (proximal closing wedge and distal chevron osteotomy) in 2008. They were assessed preoperatively and one year and two years after surgery, with clinical and radiological AOFAS MTP-IP score. All patients were satisfied. The AOFAS score improved from 34 to 84. The postoperative radiological assessment showed significant improvement, compared with preoperative values of the intermetatarsal and hallux valgus angles. No complications were encountered. Post-operative stiffness of the first MT joint was observed but resolved after physiotherapy. This preliminary study showed that correction of severe hallux valgus deformity by percutaneous double osteotomy can achieve good clinical and radiological results. A larger number of cases with a longer follow-up is needed to firmly demonstrate the advantages of this technique compared with classical open surgical techniques in the treatment of severe hallux valgus deformities.
