Abstract:
Objective To investigate the clinical efficacy of induced membrane technique for reconstruction of large tibia bone defects in adults.Methods From February 2010 to February 2014,28 cases with tibia bone defect (16 cases caused by traumatic,9 cases caused by chronic osteomyrlitis,and 3 cases caused by tumor resrction)were treated in our deparment.There were 21 males and 7 females,with a mean age of 36.7 years old.The mean bone loss after final debridement and tumor resrction was (6.2 ±2.6)cm,and the maximum length of bone loss was 16 cm in this series.All the patients were treated by induced membrane technique,and the healing rate,occurrence of complications and limb function were recorded.The bone union was assessed by Paley scores.Results The average duration of follow-up ranged from 12 to 37 months,averagely (23.4 ±4.7)months.The healing rate was 85.7% at a mean time of 5.2 months.According to the Paley scores,there were 20 cases of excellent,6 cases of good,2 cases of moderate.There were 2 patients with pin site infection,2 patients with deep infection re-quiring operative debridement,1 patient with superficial iliac incision infection,1 patient with nonunions of one ends of the bone gap,and 1 patient suffered the implant failure due to fullweight-bearing early.Conclusion The induced membrane technique is a valid option for the management of large tibia bone defects in adults caused by traumatic,tumor resection and removal of chronic osteomyelitis lesions,which sig-nificantly shorten treatment cycle,provide satisfactory results with minimal complications,and promote good recovery of limb function.
