  • Title: Prediction of disturbed healing in femoral neck fracture. Radiographic analysis of 149 cases.
    Author: Alho A, Benterud JG, Rønningen H, Høiseth A.
    Journal: Acta Orthop Scand; 1992 Dec; 63(6):639-44. PubMed ID: 1471513.
    Abstract:
    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.
