Corrective Realignment Arthrodesis of the First Tarsometatarsal Joint Without Wedge Resection.

Abstract

Moderate to severe hallux valgus (HV) has traditionally been treated with a corrective osteotomy or a tarsometatarsal arthrodesis. Tarsometatarsal arthrodesis can be performed as a planar wedge resection or using a joint curettage technique. Little is known about whether adequate correction can be obtained with purely a joint curettage technique. The purpose of this study is to evaluate the corrective power of a first tarsometatarsal joint (TMTJ) arthrodesis using a nonplanar wedge curettage technique. A retrospective radiograph and chart review was performed on 99 consecutive patients (110 feet) who underwent a first TMTJ arthrodesis for primary HV correction utilizing a curettage technique. The radiographic measurements collected were the first intermetatarsal angle, HV angle, and tibial sesamoid position and were obtained at the following intervals: preoperative, immediate postoperative, and 6 months postoperative. In all, 91 patients (100 feet) qualified for statistical analysis. There was a significant decrease in all 3 measurements from the preoperative throughout the entire postoperative time period (P < .001). The authors demonstrate the ability to achieve significant angular correction with a joint curettage method for a tarsometatarsal arthrodesis. Therapeutic, Level IV: Case series.
