为探索一种骨髓炎病理性骨折处理不当所致小儿股骨中下段骨不连接的治疗方法,采用自行研制的半圆形动态交锁髓内钉(SemicircularDynamicLockedIntramedularyNail,SDLIN)治疗15例。它由内外侧钉组成,分别自骺线上1.5cm处股骨内外侧进钉,钉尾上横栓。各病例均作自体髂骨植骨。随访3~27月,平均16.3月。骨折全部愈合,平均愈合时间4.8月,优良率86.7%。SDLIN具有力学结构合理、方法简单、效果可靠及不需在透视下操作等特点,且不伤及骨骺,不因骨折处骨质缺损、邻近骨骨质疏松而影响固定效果。
In order to explore a method for the treatment of osteonecrosis in the middle and distal femur in children with osteomyelitis due to improper handling of pathological fractures, 15 cases were treated with self-developed Semicircular Dynamic LockedIntramedulary Nail (SDLIN). It consists of a nail inside and outside, respectively, from the epiphyseal line 1.5cm at the femur into the nail inside and outside, nail tail on the lateral bolt. All cases were autologous iliac bone graft. Follow-up 3 to 27 months, an average of 16.3 months. All fractures healed, the average healing time of 4.8 months, the excellent rate of 86.7%. SDLIN has the advantages of reasonable mechanical structure, simple method, reliable effect, and no need to operate under fluoroscopy. It does not hurt the epiphysis and does not affect the fixation effect due to the bone defect at the fracture site and the adjacent osteoporosis.
