自身增强可吸收螺钉在松质骨部位骨折固定的效果评价

Evaluation on absorbable self-reinforced screws in the internal fixation of fractured cancellous bone

目的:评价自身增强可吸收螺钉在松质骨部位骨折内固定中的应用价值。方法:解放军第四五四医院骨科于1998-06/2005-05采用自身增强可吸收螺钉、棒为37例松质骨部位骨折患者行内固定术(自身增强聚乙交酯、聚丙交酯螺钉:螺纹径3.5～4.5mm,杆径2.0～3.2mm,长度25～70mm;自身增强聚乙交酯、聚丙交酯棒:直径2.0～3.2mm,长度30～70mm)。术后以肢体局部功能恢复和不同时期X线片检查结果综合判断疗效。结果:术后平均随访18个月,无一例发生感染、无菌性炎症反应、骨溶解现象。疗效:优27例,良5例,可4例,差1例,优良率86.48%。结论:自身增强可吸收聚乙交酯、聚丙交酯螺钉是非承重的松质骨骨折、关节内骨折的理想内固定物,其明显的优点在于避免了再次手术,减少了感染机会,使用简便,不干扰放射影像,不影响关节内骨折的愈合。

AIM： To evaluate the application of absorbable self-reinforced screws in the intemal fixation of cancellous bone fracture. METHODS： From June 1998 to May 2005, the absorbable self-reinforced screws and sticks were used for 37 fracture intemal fixation patients in Department of Orthopaedics, the 454 Hospital of Chinese PLA. （The absorbable self-reinforced polyglycolide and polylactide materials were adopted： the diameter of screw thread was 3.5-4.5 mm, the diameter of bolt was 2.0-3.2 mm, the length was 25-70 mm; The diameter of the stick was 2.0-3.2 mm, the length was 30-70 mm）. The curative effect was judged comprehensively by the functional recovery of local limbs and X-ray checks at different stages. RESULTS： All patients were followed up for average 18 months without infection, aseptic inflammation or osteolysis. The curative effect was evaluated as： excellent in 27 patients, good in 5 patients, fair in 4 patients, and poor in 1 patient, the general percentage of fineness was up to 86.48%. CONCLUSION： The absorbable self-reinforced polyglycolide and polylactide screw is a rational option in fracture intemal fixation of cancellous bone and inside joint, The evident forte of the absorbable self-reinforcad screw is the ineffective healing of fracture, avoiding second operation, decreasing infection, applying conveniently and no interference on X-ray check.
