Abstract
The purpose of the present study is to report a new method for treating unstable intertrochanteric fractures using DHS (dynamic hip screw), TP (trochanter stabilizing plate), CCS (cannulated cancellous screw), and β-TCP (β-tricalcium phosphate). We particularly report the effectiveness of β-TCP for medial bone defects at the femoral neck.Twenty-five subjects were treated by the new method from May 2004 to December 2004 and compared with twenty-one subjects, treated by the conventional method without β-TCP, from April 2003 to April 2004.The average neck shortening was 6.0 mm in the new method group, compared with 9.6 mm in the conventional method group.The results of the investigation suggest that β-TCP prevents neck shortening in unstable intertrochanteric fractures.
