| [Objective] To discuss a reasonable treatment for intertrochanter fracture of femur by comparison of Effects and Biomechanical study between DHS and LCP fixation, to provide a theoretical basis for guiding clinical treatment with this type of fracture. [Method] Take the method of analysing biomechanical study and clinical case. Totally 65 intertrochanteric hip fractures in our department,s patients with complete clinical data were retrospectively analyzed, who were treated with DHS or LCP fixation from January. 2006 to December. 2008. The two groups both are given more than one year of follow-up respectively. 39 were treated with DHS, 26 were treated with LCP fixation. All of them had excluded pathological fractures and severe multiple trauma.χ2 test and t test was used in comparing between the two treated groups in terms of the operative time, the blood lost, during or after surgery time for bed rest postoperative, postoperative complications and St. Michael hip score one year after surgery. Meanwhile, to test fractures internal fixation stability under axial compression in universal mechanics test instrument. [Result] Compared with the group of DHS, the group of LCP fixation experienced longer time for bed rest postoperatively(P<0.05), Whereas the differences in the operative time, the blood lost during or after surgery, and the postoperative implant complications, St. Michael hip score one year after surgery between two groups had of no statistical significance (P >0. 05). LCP fixation model is superior to the DHS internal fixation model. [Conclusion]Both of the two methods are reasonable treatment for intertrochanteric hip fractures in patients. |
