Prediction of disturbed healing in femoral neck fracture. Radiographic analysis of 149 cases.
To determine factors predictive of early healing disturbances after fixation of femoral neck fracture, the radiographic and clinical data of 149 patients were subjected to a logistic regression analysis comparing them with the results 3 months postoperatively. As in previous studies, fracture reduction distinguished between fractures with or without healing disturbances. The following signs in the preoperative radiographs were predictive of unfavorable outcome: small head fragment, comminution of the calcar femorale, and varus angulation of the head. Fractures with negative predictive signs may be selected for primary arthroplasty.
