RESUMO
BACKGROUND: Fifth metatarsal Jones fractures are common in the athletic population. Optimal screw selection for operative treatment has not been determined. HYPOTHESIS: A 4.5-mm cannulated screw used for fixation of the fifth metatarsal Jones fractures in athletes is an effective treatment approach. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The 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. RESULTS: There 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. CONCLUSION: Fixation with a stainless steel 4.5-mm cannulated screw gives 100% clinical healing and near-100% healing as shown on radiographs. CLINICAL RELEVANCE: The 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.
