Fifth Metatarsal Jones Fracture Fixation with a 4.5-mm Cannulated Stainless Steel Screw in the Competitive and Recreational Athlete

Abstract

BackgroundFifth metatarsal Jones fractures are common in the athletic population. Optimal screw selection for operative treatment has not been determined.HypothesisA 4.5-mm cannulated screw used for fixation of the fifth metatarsal Jones fractures in athletes is an effective treatment approach.Study DesignCase series; Level of evidence, 4.MethodsThe authors studied 23 consecutive athletes (24 feet) who were treated surgically with a 4.5-mm cannulated screw for fifth metatarsal fractures (Jones fracture) with clinical and radiographic assessments.ResultsThere have been no refractures to date. Clinical healing was 100%. The mean percentage healing as shown on radiographs was 98.9%, with a range of 90% to 100%. All athletes returned to sport at a mean time of 7.5 weeks (range, 10 days to 12 weeks). Two athletes experienced a “reinjury” without need for operative treatment. All athletes were recommended to wear orthoses until their competitive careers were completed.ConclusionFixation with a stainless steel 4.5-mm cannulated screw gives 100% clinical healing and near-100% healing as shown on radiographs.Clinical RelevanceThe 4.5-mm cannulated screws can yield reliable and effective healing as evidenced by clinical assessment and radiographs of fifth metatarsal Jones fractures in athletes.
