Abstract
We discussed the clinical results of trochanteric fractures which were treated with Intramedullary Hip Screw (IMHS) and Compression Hip Screw (CHS). In a total of 69 cases (19 males, 50 females), the fracture type was assessed by the Evans' classifcation system. 24 cases (2 stable and 22 unstable types) were treated with IMHS from February 1994 to July 1995. 45 cases (9 stable and 36 unstable types) were treated with CHS from May 1992 to January 1994.
Considering mean surgicaly time, mean intraoperative blood loss, and mean post operative transfusion, IMHS seemed to show more operative disadvantages for the patients than CHS.
In stable fractures, the postoperative mean sliding amount of the lag screws was about the same in both groups. However in unstable fractures, the amount was obviously less in the case of IMHS than in that of CHS. Because of the rigid fixation, IMHS allowed for early weight-bearing, short periods of bed-rest, and an expected good post operative result. The clinical results were better in the IMHS group than in the CHS group.
