[目的]探讨120°儿童髋锁定加压钢板(120°Locking compression paediatric hip plate,120°LCP PHP)治疗儿童股骨转子下骨折的临床疗效。[方法]2010年10月~2014年5月采用120°LCP PHP治疗儿童股骨转子下骨折16例。[结果]本组患儿术后随访24~36个月,平均(27.3±3.2)个月。无1例发生神经血管损伤、骨折端再移位、再骨折、髋内翻、骨髓炎、股骨头坏死及骨骺发育异常。骨折骨性愈合时间为8~13周,平均(10.1±1.4)周,无骨不愈合。于术后18~32周取出内固定物,平均(25.3±3.4)周。早期Beaty评分及远期Theologis评分皆为满意,术后2年Sanders髋关节评分为57~60分,平均(58.7±2.1)分,都为优,优良率为100%。[结论]120°LCP PHP治疗儿童股骨转子下骨折,具有符合儿童股骨转子下解剖及生物力学特点、固定牢固、避免损伤骨骺、骨折愈合快、并发症少、适应证广、可早期功能锻炼等优点。但存在需要切开复位、损伤相对较大、出血较多、二次手术切开取出内固定物、费用较高、切口瘢痕影响美观等缺点。
[Objective] To investigate the clinical effect of 120 ° Locking Compression Pediatric hip plate (120 ° LCP PHP) on subtrochanteric fractures in children. [Method] From October 2010 to May 2014, 16 cases of subtrochanteric femoral fractures were treated with 120 ° LCP PHP. [Results] This group of children were followed up for 24 to 36 months, with an average of (27.3 ± 3.2) months. None of the cases occurred neurovascular injury, fracture displacement, then fracture, hip varus, osteomyelitis, osteonecrosis and epiphyseal dysplasia. Bone fracture healing time was 8 to 13 weeks, with an average of (10.1 ± 1.4) weeks, bone nonunion. The internal fixation was removed 18 to 32 weeks after operation, with an average of (25.3 ± 3.4) weeks. Both the early Beaty score and the long-term Theologis score were satisfactory. The Sanders hip score was 57-60 in two years after operation, with an average of (58.7 ± 2.1) points. Both were excellent and the excellent and good rate was 100%. [Conclusion] 120 ° LCP PHP treatment of children under the femoral subtrochanteric fractures, in line with the anatomy and biomechanics of children femoral trochanter, fixed firmly, to avoid damage to the epiphyseal, rapid fracture healing, fewer complications, indications, and early functional exercise advantage. But there is a need to open reduction, injury is relatively large, more bleeding, the second surgical incision and removal of the fixture, the higher the cost, the impact of incision scar and other shortcomings.
