| Objective To observe the clinical effect of PFNA and Intertan system in the treatment of femoral intertrochanteric fractures in senile osteoporotic patients by analyzing the selection of intramedullary fixation. Methods From November 2010 to April 2011, 61 patients with femoral intertrochanteric fractures were treated in our hospital. Among them, 37 patients were treated with PFNA, and 24 patients were treated with Intertan. The average operation time, interaoperative bleeding, mean healing time, partial-weightbearing time, entire-weightbearing time, postoperative complications, numbers of failed internal fixations, and Harris hip score in both groups were compared. Results All the patients were foliowed-up for 6-24 months, with an average of 13. 3 months. Harris hip score acquired at the last follow-up was recorded. Comparing to patients in Intertan group, patients in PFNA group had shorter operative time and less blood loss ( P < 0. 05 ) . Comparing the length of incision, mean healing time, partial-weightbearing time, entire- weightbearing time, postoperative complications, numbers of failed internal fixationsy and Harris hip score between both groups, no significant differences were observed ( P > 0. 05 ) . Conclusion The design of both PFNA and Intertan system is reasonable. Both have good fixation effect in the treatment of femoral intertrochanteric fractures in senile osteoporotic patients and can achieve clinical cure. |
