Treatment of Jones fracture nonunion with isolated intramedullary screw fixation.

Abstract

Although the treatment of acute Jones fractures is well described in published studies, the Jones fracture nonunion is more controversial with regard to treatment. Although nonoperative treatment is an option, surgery is the usual course. We conducted a retrospective case series of 7 patients (1 man and 6 women; age range 39 to 54 years), who were initially treated nonoperatively for acute Jones fractures. They went on to develop nonunions and were treated with intramedullary screw fixation. All patients had healed radiographically by 11 weeks postoperatively. One screw (14.29%) required removal because of irritation. None of the patients to date have experienced a new fracture. Our results indicate that intramedullary screw fixation alone without bone grafting is a viable option for Jones fracture nonunions.
