摘要
目的:探讨自身增强型可吸收内固定系统,治疗颌面部骨折的可行性。方法:应用自身增强型可吸收内固定系统治疗43例各型颌面部骨折,观察术中、术后固位情况,术后并发症及术后吸收情况。结果:43例中,1例发生术后感染,1例发生后期非特异性炎性反应;所有病例骨折愈合良好,无骨愈合延迟或骨断端明显移位。术后吸收时间为1.5～3a不等,部分患者颧眶区未能完全吸收。结论:自身增强型可吸收内固定系统能为颌面部骨折提供良好的内固定,并有其自身的优点;其缺点是螺钉易折断,不同的个体其降解时间不一致,部分病例不能完全降解。
PURPOES: The purpose of this study was to evaluate the effectiveness of self-reinforced P(L/D)LA internal fixation system for oral maxillofacial fractures. METHODS: The system was used in 43 patients. The reduction situation during and after operation, postoperative complications and degradation time were recorded. RESULTS: The postoperative complications were one case with postoperative infection and one case with late noninfectious inflammatory tissue response, but these were controlled by routine treatment. Bone healing was satisfactory in all cases, without delay of bone union or obvious displacement of fracture segments after surgery. The degradation time ranged from one and half years to three years, the system remained in orbital and zygomatic areas and cannot be degraded completely. CONCLUSIONS: The SR-P(L/D)LA system provided effective and stable fixation for maxillofacial fractures. The system has some defaults: the screws are broken easily, different degradation time in different individuals and incomplete degradation in some patients exist.
