Osteosynthesis for Femoral Neck Fractures with Compression Hip Screw and Cannulated Cancellous Screw

We treated 48 cases of femoral neck fractures between March 1998 and April 2000. The patients, consisting of 10 males and 38 females with a mean age of 72 years, were treated using compression hip screw (CHS) and cannulated cancellous screw (CCS). The purpose of this study was to investigate their clinical results. The bony union rate was 89% in Garden stages I and II and 72% in stages III and IV. There was a significant difference between bony union and alignment index (P<0.05) value. The most important factor was the quality of reduction.
