BACKGROUND: Recently, various femoral @entity135 ( @entity135 ) for @entity173 have become available. However, there are some cases in which femoral @entity717 with excessive sliding of the HFD is observed and it is often followed by cutout. The purpose of this study is to compare the ability of the three types of @entity135 to prevent femoral @entity717 . METHODS: Between July 2005 and December 2009, 206 @entity1 aged over 60 years with @entity173 who had undergone surgical treatment using a short femoral nail in our institution were enrolled into the study. We used the gamma 3 nail (GMN) as the screw-type HFD in 66 cases, the gliding nail (GLN) as a non-cylindrical blade in 76 cases, and the proximal femoral nail antirotation (PFNA) as a cylindrical blade in 64 cases. The sliding length of @entity135 and the occurrence of femoral @entity717 were evaluated by assessing radiographs as the main outcome, and the results were compared among these devices. RESULTS: A comparison of the degree of sliding in the GMN group showed that femoral @entity717 was observed significantly more frequently in cases with rotation. Further, it appeared that femoral @entity717 occurred more frequently in comminuted @entity174 . However, no significant differences between the sliding lengths of the different @entity135 were observed among three groups. @entity717 was observed in 15 cases of GMN (22.7%), 0 case of GLN, and 5 case of PFNA (7.8%). Significant differences with regard to the occurrence of femoral @entity717 were observed among the three groups. Furthermore, significant differences were also observed between GLN and PFNA with respect to the occurrence of femoral @entity717 . CONCLUSIONS: The ability to stabilize femoral head appears to be greater with blade-type materials than with screw-type materials. Furthermore, we believe that a non-cylindrical blade is preferable to a cylindrical blade for the surgical treatment of comminuted, unstable @entity173 in order to prevent femoral @entity717 and cut-out.
