Abstract

PURPOSE: To evaluate the difference between dynamic hip screw and cannulated screw for stability, complication and patient s functional recovery in intracapsular fracture of femoral neck.
MATERIALS AND METHODS
Eight-four patients were randomly assigned into dynamic hip screw fixation and cannulated screw fixation groups. Clinical information included age and sex distribution, operation time, total blood loss, interval from injury to operation, etiology of fracture, associated fracture, and functional outcome. Preoperative X-ray information included fracture type by Garden stage, Singh index, and posterior comminution. Postoperative information included quality of reduction, pin and screw position, Garden alignment index, evidence of union, complication and failure.
RESULTS
No difference was noted between the two fixation methods regarding gender, initial fracture displacement, postoperative reduction or position of the fixation device, functional outcome using Robinson's method, and complication. In operation time and total blood loss, however, cannulated screw fixation group was significantly lower (P<0.05).
CONCLUSIONS
Therefore, to decrease operation time and blood loss, cannulated screw fixation was considered to be more useful as a fixation method in a intracapsular fracture of femoral neck.
