title: Fifth metatarsal Jones fracture fixation with a 4.5-mm cannulated stainless steel screw in the competitive and recreational athlete: a clinical and radiographic evaluation.
abstract: BACKGROUND
  Fifth metatarsal Jones fractures are common in the athletic population. Optimal screw selection for operative treatment has not been determined.
  
  
  OBJECTIVE
  A 4.5-mm cannulated screw used for fixation of the fifth metatarsal Jones fractures in athletes is an effective treatment approach.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  Fixation with a stainless steel 4.5-mm cannulated screw gives 100% clinical healing and near-100% healing as shown on radiographs.
  
  
  CONCLUSIONS
  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.
