Abstract

PURPOSE: To prepare the appropriate guideline in choosing the internal fixatives for the intertrochanteric fractures of the femur in the elderly.
MATERIALS AND METHODS
We reviewed 95 cases of intertrochanteric fractures of the femur from January, 1999 to December, 2003. We fixed the fracture with Proximal Femoral Nail in 37 cases (PFN group), Dynamic Hip Screw in 56 (DHS group), Dynamic Condylar Screw in 2 cases (DHS group). We reviewed operation time, blood loss during operation, changes in neck-shaft angle and sliding of lag screw.
RESULTS
There were no significant differences in the parameters between the 2 groups in stable fracture. In unstable fractures, operation time in PFN group and DHS group revealed 103.9 and 128.2 minutes respectively; mean amount of blood loss during operation revealed 523.2 and 573.1 ml respectively. Mean changes in the neck-shaft angle at final follow-up in PFN group and DHS group revealed 4.6 degrees and 4.1 degrees; sliding of lag screw averaged 3.4 and 6.5 mm respectively. Among the DHS group, cases of additional fixation with trochanteric supporting plate revealed 3.1 degrees of changes in neck-shaft angle and 4.2 mm of lag screw sliding.
CONCLUSION
In cases of stable fractures, any fixative might suffice. In cases of unstable fractures, there were no significant differences in results of treatment between these two groups, however, PFN group revealed shoter operation time and less blood loss during operation. It seemed to be necessary to apply additional fixation with trochanteric supporting plate when using DHS in unstable cases.
