Purpose: This study was designed to compare the clinical and radiological results of intramedullary fixation to those of extramedullary fixation in patients with reverse oblique or transverse intertrochanteric femoral fractures.
Materials and Methods: We retrospectively reviewed 39 cases of reverse oblique or transverse intertrochanteric femoral fractures between September 2001 and December 2010. There were 20 cases treated with intramedullary fixation (Group I) and 19 cases treated with extramedullary fixation (Group II). The operative time, intraoperative blood loss, amount of blood transfused, hospital day, and time to bone union were compared between the two groups. Radiologically, the osition and sliding length of the lag screw or blade, change of femoral neck-shaft angle, and medialization of distal fragment were compared. Also, complications were assessed.
Results: The mean operative time was 87.8 minutes with Group I and 153.8 minutes with Group II. The mean intraoperative blood loss was 375.0 ml with Group I and 1,015.8 ml with Group II. The mean amount of transfusion was 555.5 ml with Group I and 801.6 ml with Group II. The mean time to bone union was 12.1 weeks with Group I and 18.1 weeks with Group II. There were no statistical differences in other parameters between the two groups.
Conclusion: The intramedullary fixation group revealed better results in the aspects of invasiveness and time to bone union in comparison with the extramedullary fixation group for the treatment of reverse oblique or transverse intertrochanteric femoral fractures.
