Synthes cable system for periprosthetic femoral fractures after total hip replacement / 中国组织工程研究

ABSTRACT

BACKGROUND:Recently, periprosthetic femoral fractures have been a common complication after total hip replacement. Vancouver type B1 periprosthetic femoral fractures commonly received internal fixation due to stable femoral prosthesis and less bone defects. OBJECTIVE:To evaluate the effect of the application of Synthes cable system in the treatment of Vancouver type B1 periprosthetic femoral fractures after total hip replacement. METHODS:From May 2009 to October 2012, 18 patients with Vancouver type B1 periprosthetic femoral fractures were treated with Synthes cable system in the Department of Orthopedics, Nantong First People’s Hospital. There were 8 males and 10 females with an average age of (62.67±8.67) years ranging 45 to 80 years. They received a further consultation at 1, 3 and 6 months after treatment. The function of hip joint was evaluated by Harrris evaluation standardful marks, 100 points, ≥ 90 points, excellent;80-89 points, better;70-79 points, good; RESULTS AND CONCLUSION:Al 18 patients were fol owed up for 6 to 43 months. Mean healing period was (19.06±4.04) weeks. Harris score was (22.3±3.6) points before treatment in 18 cases. Harris score was higher significantly at 1, 3 and 6 months after treatment compared with that before treatment (P<0.01), and the recovery of hip function was good. Results indicated that Synthes cable system could help to restore the normal anatomic structure of femur in the greatest extent, showing simple operation, little injury, high stability and high safety. It is an ideal method for treating Vancouver type B1 periprosthetic femoral fractures.
