Abstract

PURPOSE: To evaluate between DHS and ITST nail (2nd generation) on the treatment of unstable femur intertrochanteric fracture in patients over 70 years old.
MATERIALS AND METHODS
61 cases of unstable intertrochanteric fracture (grouped 37 patients with DHS and 24 patients with ITST) who were taken the operation from Mar. 2003 to Sep. 2007 were analysed regarding to union time, sliding length of lag screws, operation time, blood loss, postoperative complications and functional recovery score by Skovron.
RESULTS
The mean union time was 14.7 weeks in study group (ITST). The mean union time was 16.2 weeks in control group (DHS). The lag screw slidings were 7.2 mm in study group and 8.7 mm in control group. The operation times were 57.9 min in study group and 76.9 min in control group. The amount of blood loss were 67.7 ml in study group and 227.4 ml in control group. The complications were 4 cases in study group and 4 cases in control group. The Skovron recovery scores were 76.5% in study group and 73.7% in control group.
CONCLUSION
From a practical point of short operation time, less amount of bleeding and less complication, author think that the ITST nail is useful implant for treatment of unstable femur intertrochanteric fracture in patient of old age.

(B, C) Immediate postoperative radiograph of internal fixation with DHS and TSP. (D, E) Postoperative 14 months radiograph shows complete union of fracture site, 3 mm slippage of lag screw and 3 degree change of neck-shaft angle without lateral displacement of greater trochanter.

(C, D) Immediate postoperative radiograph shows that fixation was done with ITST, lag screw was placed in center. (E, F) Postoperative 8 months radiograph shows complete union of fracture site, 2 mm slippage of lag screw.
