title: [Analysis of complication factor after treatment of intertrochanteric fractures with gamma nail].
abstract: OBJECTIVE
  To analyse the factors of complications after treatment of intertrochanteric fractures with Gamma nail.
  
  
  METHODS
  From January 1998 to May 2004, 50 patients were treated with Gamma nail, including 18 males and 32 females and ageing from 47 to 82 years. The locations were the left side in 16 cases and the right in 34 cases. According to Evans classification, there were 4 cases of type I, 2 cases of type II, 23 cases of type III, 10 cases of type IV and 11 cases of type V.
  
  
  RESULTS
  Fifty patients were followed up 4-29 months. According to the Harris criterion for evaluation, the results were excellent and good in 35 cases, showing sthenic weight loading walking and normal range of motion of the hip joint. The postoperative complications appeared in 15 cases: 5 cases of coxa vara or coxa valga, 3 cases of rotation deformity of lower limb, 2 cases of tension screw protrusions and lower shorten, 1 case of failure of internal fixation, 1 case of femoral fracture, 2 cases of coxalgia and 1 case of pain in knee joint and stiff knee joint.
  
  
  CONCLUSIONS
  The reason of complications was various, mainly lies in insufficient comprehension and analysis of the types of fractures, unfamiliarity with the characteristics and usage of the instruments and neglected rehabilitation instruction, inappropriate functional training and too early weight loading after operation.
