可吸收螺钉在近关节端松质骨骨折中的应用

目的：评价可吸收螺钉在近关节端松质骨骨折临床应用效果。方法：本组32例，平均年龄35岁。使用65枚可吸收螺钉治疗四肢关节端松质骨骨折，术前、手术当天及术后定期摄X线片，并观察局部及全身反应情况。结果：术后平均随访12个月（6个月～3年），所有病例骨折对位良好，达骨性愈合。肢体功能和关节活动无明显异常，无非特异性炎症反应表现。结论：可吸收螺钉是近关节端松质骨骨折的理想内固定物，固定效果确切，生物相容性好，对人体无不良反应，不影响关节内骨折的愈合，免除二次手术取内固定物的痛苦。

Application of absorbable screws in treatment of fractures of spongy bone near joints

Objective： To evaluate the clinical effects of absorbable screws in treatment of fractures of spongy bone near joints. Methods： 32 patients with fractures of spongy bone near limb joints were treated with 65 absorbable screws. Their average age was 35 years old. They took regular X-ray examinations preoperatively, on the day of operation and postoperatively to observe their loca/and systemic reactions. Results： All the cases were followed up for 6 months to 3 years, with an average of 12 months. Good apposition and bony union were achieved in all fhe cases. Their functions of joint were normal and no nonspecific inflammatory reactions were observed. Conclusion： The absorbable screw is an ideal internal fixation device in the treatment of fractures of spongy bone near joints, because it has a definite effect of fixation but no barmful effects on fracture healing or human body, and good bioeompatibility which can spare the patients the pain saused by the operation to remove the implants.
