Abstract:
Objective To assesses the value of the Pipkin fracture classification on the treatment and prognosis of Pipkin fracture. Methods A total of 71 patients with Pipkin fractures treated from January 2002 to January 2007 were followed up and the detailed information of 63 patients were obtained. The clinical and radiographic evaluation criteria of Thompson was employed to evaluate the outcome, analyze the results and discuss the correlation between Pipkin fracture type and prognosis and hence propose the significance of Pipkin classification on the prognosis. Results There was no statistical difference in aspect of the outcome between type Pipkin Ⅰ , Ⅱ injury and type Pipkin Ⅳ injury (types Pipkin Ⅰ and Ⅱ injury combined with minimum fracture, with fragment ＜ 1 cm,P＞0. 05). There showed statistical difference in outcome between types Pipkin Ⅰ , Ⅱ injury and type Pipkin Ⅳ injury (types Pipkin Ⅰ and Ⅱ injury combined with acetabular rim fracture, P ＜0. 05). Conclusions Pipkin fracture classification system needs a further improvement. The type Pipkin Ⅳ injury that is combined with types Pipkin Ⅰ , Ⅱ , Ⅲ injuries with minimum fracture (fragment ＜ 1 cm) of the acetabular rim should be incorporated into types Pipkin Ⅰ ,Ⅱ , Ⅲ injury. Type Pipkin Ⅳ injury refers to types Pipkin Ⅰ ,Ⅱ , Ⅲ injuries, with major fracture of the acetabular rim and the hip joint instability. In addition, the Pipkin fracture type involving the fracture line, femoral neck and intertrochanteric region is hard to treat clinically and has poor prognosis, suggesting that this type of injury should be considered as special type Pipkin Ⅲ injury.
