当科における大腿骨転子部骨折の手術成績―ＣＨＳとγ‐ｎａｉｌの比較―

Abstract

Between April 1999 and September 2004, 58 cases of femoral trochanteric fractures were treated with a CHS (compression hip screw), and 25 cases with a Gamma nail. We evaluated the multivariate studies and the post-operative walking ability between two groups. There were significant differences in the duration of admission, fracture types, post-operative walking ability in unstable fracture type, and complications. Because of the operative-technique, complications in the Gamma group were more than the CHS group. In the unstable fractures type, 88 percent of the patients in the Gamma group regained pre-injury walking ability, but only 40 percent in the CHS group regained the ability. In the decreased factors of walking ability, there were significant differences in unstable fractures type and dementia of the CHS group. We conclude that the Gamma nail is a more useful device than CHS in unstable fractures type and dementia.
