title: [Treatment of conmminuted patellar fractures with internal Ni-Ti patellar concentrator and tension bind wire fixation].
abstract: OBJECTIVE
  To study the clinical efficacy of the treatment of comminuted patellar fractures with internal NiTi-Patellar concentrator and tension bind wire fixation.
  
  
  METHODS
  From March 2004 to June 2007, 38 cases of fresh comminuted patellar fractures were treated with internal NiTi-Patellar concentrator and tension bind wire fixation. There were 25 males and 13 females,ranging from 21 to 64 years (mean 42.5 years). All were comminuted fractures with displacement, 16 cases were 3 fragments, 14 cases were 4 fragments, 8 cases were 5 fragments. There were other fractures in 8 cases. During followed-up, knee function and complications were evaluated.
  
  
  RESULTS
  All patients were followed up for 8 to 24 months (mean 15 months) and obtained complete bone union. No case of implant was loosening and fragment displacement, traumatic arthritis occured in 2 cases. Under Lysholm & Gillquist score, the results were excellent in 17 cases, good in 19, fair in 2.
  
  
  CONCLUSIONS
  Internal Ni-Ti-Patellar concentrator and tension bind wire fixation is one of the ideal methods for the treatment of comminuted patellar fracture, which could provide satisfied reduction, reliable fixation and good functional recovery.
