Abstract:
Eleven patients with small or comminuted displaced tibial avulsion fractures of posterior cruciate ligament admitted in the Department of Orthopaedics,Second Affiliated Hospital,Fujian Medical University between January 2003 and January 2008 were selected.With diameter of 4.0 mm,the length of 35 mm or 40 mm cancellous bone screw,and internal diameter of 4.0 mm spiked washer was implanted for fixation.For cases of large comminuted facture,two cancellous bone screws and spiked washer were used.Postoperatively,the limb was immobilizated in a cast plaster at a 30 degrees flexion for 2-4 weeks,followed by active exercise rehabilitation.All 11 patients were followed up with an average of 18 months(ranged 7 to 36 months).No electrolysis,corrosion reaction to metal material,or allergic response to the spiked washer were detected in patients.At 2 months,all patients achieved bony union,no fragment redisplacement,no knee laxity or instability was detected,and the affected knees regained full range of motion.The knee function was significantly improved.
