title: [Application of Ni-Ti patellar concentrator combined with Herbert screw and wirerope for the treatment of comminuted patellar inferior pole fractures].
abstract: OBJECTIVE
  To evaluate the surgical techniques and clinical effect of Ni-Ti patellar concentrator combined with Herbert screw and wirerope in treating comminuted patellar inferior pole fractures.
  
  
  METHODS
  From March 2008 to June 2010,34 patients with comminuted patellar inferior pole fracture were treated with Ni-Ti patellar concentrator combined with Herbert screw and wirerope. Of them, there were 19 males and 15 females with an average age of 38.6 years old(ranged from 22 to 75). Early functional exercise was guided postoperatively and the patients were regularly followed up and their outcomes were assessed.
  
  
  RESULTS
  All patients were followed up with an average of 13.5 months (ranged,7 to 20). All fractures healed. According to Böstman Clinical Rating System, the average score was 28.43 +/- 2.34,and excellent results in 21 cases,good in 13 cases and no poor case.
  
  
  CONCLUSIONS
  Ni Ti patellar concentrator combined with Herbert screw and wirerope for the treatment of comminuted patellar inferior pole fracture is an effective method and of great value to clinical application.
