ABSTRACT: To investigate the results and indication of differently internal fixation for intertrochanteric fracture and prevent for complication.
One hundred and two patients of intertrochanteric fracture of femur from January 1997 to December 2007 were reviewed and analysed. There were 46 males and 56 females, with an average age of 76.5 years ranging from 60 to 93 years. There were 34 cases of stability fractures and 68 of instability fractures. The methods of internal fixation included dynamic hip screw in 82 cases, proximal interlocking nail in 5, multi-screw fixation in 9, dynamic codylar screw in 6.
These patients were followed up for 6 to 72 months (36 months in average). The time of fracture healing was from 8 to 12 weeks. According to evaluation criterion of effect, the results were excellent in 72 cases, good in 20, fair in 10. After operation, there were 3 cases of coax vara, 2 cases of lag screws cutting out, 1 case of breakage of screw, 2 cases of avascular necrosis of the femoral head, 1 case of postoperative infection, 1 case of delayed union.
Suitable implant selection according the type of fracture, health condition is an important factor to reduce the incidence of complication for unstable fracture in aged patients. DHS is a main treatment of intertrochanteric fracture. PFN is recommended for serious osteoporosis or unstable intertrochanteric fracture. Compression screws is a choice for the fixation of type I and type II fracture of bad health condition.
