【摘要】 目的探讨下肢长骨干骨折成角愈合发生原因和对策。方法分析12例股骨、胫腓骨干骨折成角愈合程度,设计截骨平面及截骨角度,恢复膝关节力线防治创伤性膝关节病。结果12例平均随访5年6个月术肢恢复正常负重力线,跛行改善,膝关节疼痛缓解,关节病发生和发展明显延缓。结论下肢长骨干骨折后成角愈合超过生理负重线基本条件后应手术治疗为好。成角矫正后可延缓膝关节骨关节炎的发生发展,矫正成角、恢复力线也是治疗膝关节病的方法。更多还原

【Abstract】 Objective To discuss the causes and treatment of angulated healing of long bone shaft fracture at lower limbs. Methods 12 cases of patients with the angulated healing of femoral and tibiofibular fractures were treated surgically in our hospital. In the operation, the plane and angle of the osteotomy were designed according to the specific angulation to restore the normal vertical alignment of the knee joint so that traumatic arthropathy of the knee could be treated or prevented. Results All the patients were followed up for 6 months to 12 years (averaging 66 months). Their lameness was greatly improved, the pain at their knee joints was relieved, and the occurrence or development of the arthropathy were obviously delayed. Conclusions When the angulation of healed long bone shaft fracture at lower limbs exceeds the physical weight bearing line, the condition should be treated surgically. The corrected angulation can delay the occurrence and development of arthritis at the knee. Moreover, corrected angulation and restored alignment is a good method to treat arthropathy of the knee joint.更多还原
