针对膜诱导技术治疗下肢股骨与胫骨骨缺损的临床安全性分析

Objective To study and analyze the clinical efficacy and safety of membrane induction technique in treating lower limb femoral and tibial bone defects. Methods From January 2022 to December 2024, 20 cases of femoral bone defects and 25 cases of tibial bone defects were treated. All patients were treated with membrane induction technique, and the treatment effect was analyzed. Results Comparison of postoperative complication incidence between the two groups showed no significant difference(P>0.05). Evaluation of lower limb motor function of patients, except for joint range of motion, there were significant differences in motor, sensory, balance, and pain scores between the two groups(P<0.05). There were no significant differences in lower limb motor function evaluation between the two groups at 1 month and 3 months after surgery(P>0.05). Comparison of long-term efficacy among groups showed no significant difference in the long-term efficacy of patients with lower limb femoral and tibial bone defects(P>0.05). Conclusion The implementation of membrane induction technique has therapeutic efficacy for lower limb femoral and tibial bone defects, and the safety and prognosis of the affected limb's motor function recovery are good. Among them, the short-term recovery during the treatment of tibial bone defect with this technique is slightly superior.
