Objective To explore the therapeutic efficacy of percutaneous compression plate internal fixation in the treatment for elder-ly patients with interchanteric fractures. Methods All 17 patients with interchanteric fractures from March 2012 to January 2013 were trea-ted with percutaneous compression plate internal fixation(Fracture classification:type A1. 2 with 3cases,A1. 3 with 4cases,A2. 1 with 6 ca-ses,A2. 2 with 3 cases,A2. 3 with 1 case). After operation,the patients did functional exercises at the early stage. Then the efficacy were e-valuated and analyzed. Results Operation time was 30~80 min,with average time 50 min, blood loss was (40~100) mL,with average volume 60 mL,time of X-ray exposure was 12~22 s,with average time 20 s. All 17 patients were followed up for 3~18 months. Postoperative function were evaluated according to Harris Hip Score,15 cases were excellent,and 2 cases were good,the excellent and good rate was 100%. Conclusion Percutaneous compression plate internal fixation is suitable for the elderly patients of interchanteric fractures,with shorter oper-ation time,less blood loss,reliable fixation and less complications.
