Abstract

PURPOSE: To investigate the relationship between the complications of intracapsular femoral neck fractures treated by multiple pinning and several affecting factors.
MATERIALS AND METHODS
Sixty-eight patients with intracapsular femoral neck fractures were treated by multiple pinning from March 1993 to January 2000 and followed at more than one year. Relationship between the complications such as failure of union, collapse of femoral head due to osteonecrosis of femoral head and several affecting factors including displacement of fracture according to Garden stage, state of reduction, position of screws, time interval from injury to operation, and fracture level were analyzed. The Fisher exact test, chi-square test, and multivariate logistic regression analysis were used to find the relevant factors influencing incidence of complications. Statistical significance was set at p < 0.05.
RESULTS
Position of screw was the most important single factor affecting the results of treatment of intracapsular femoral neck fracture (p=0.046). Moreover, the Garden stage and position of screw were revealed affecting the incidence of complications together with other factors (each p value was 0.028 and 0.027).
CONCLUSION
We considered that satisfactory position of screw was important to reduce complications after multiple pinning for intracapsular femoral neck fracture. And the results of operation also seemed to closely relate with multiple factors including Garden stage and status of reduction.
