title: [Surgical treatment of internal fixation failure after clavicular fracture operation].
abstract: OBJECTIVE
  To investigate the surgical treatment results of implant failure after clavicular fracture open reduction and internal fixation (ORIF).
  
  
  METHODS
  Fifteen cases from Jan. 2005 to Jan. 2013 were treated surgically according to fracture classification, time of implant failure and implant type. The fracture union, shoulder function and pain were evaluated postoperatively.
  
  
  RESULTS
  All the patients had full follow-up for 5 to 101 months (mean: 43.8 months). All the fractures were united well. The constant scores to assess the shoulder function were 82 to 100 (mean: 93.3 in the fracture side) and were 85 to 100 (mean: 96.7 in the uninjured side); statistically significant difference of the constant scores between the two sides was found (P=0.02). Eight cases did not have shoulder pain in the fracture side, while the other 7 cases had mild pain, The visual analogue scale (VAS) scores to evaluate shoulder pain were 1 to 3 in the fracture side, which were statistically different from those in the uninjured side (P=0.03).
  
  
  CONCLUSIONS
  Implant instability causes early implant failure after clavicular fracture ORIF and re-fixation with stable implant is effective. Fracture nonunion leads to late implant failure, and bridging fixation using locking plate associated with bony autograft with iliac crest is a successful method to treat atrophy clavicular nonunion. Surgical treatment can bring good results.
