可吸收材料在骨折内固定中的临床应用

Clinical application of absorbable materials in the fracture fixation

背景:骨折治疗时选择合适的内固定物相当重要,否则极易导致治疗失败。临床上治疗骨折的内固定物以金属材料为主,在人体内易出现腐蚀和应力遮挡引起皮质骨疏松;另外骨折愈合后需二次手术拆除,可致再次骨折。目的:分析可吸收材料的生物特性及治疗骨折的适应症,并比较可吸收材料在骨折内固定中的特点。方法:收集不同可吸收材料治疗骨折的相关文献,找出治疗对象相似、疗效评价标准相同的病例进行分析。结果与结论:采用可吸收材料治疗骨折具有显著优越性,可吸收材料不需要二次手术取出,对关节周围组织及关节本身损伤小,组织相容性好,并发症少,是骨折内固定治疗的发展方向之一。

BACKGROUND： It is important to select the suitable fixity for the treatment of fractures, otherwise, it is easy to lead to the treatment failure. In clinic, the fixity used for the treatment of fractures is mainly the metal materials, but the metal materials are prone to corrosion and stress shielding cause cortical bone osteoporosis in human body; in addition, second surgery is needed to remove the materials after fracture healing which can cause the secondary fracture.OBJECTIVE： To analyze the biological properties of the absorbing material and the indications of fracture treatment, and to compare the characteristics of absorbable materials in the fracture internal fixation.METHODS： The articles related to the absorbable materials for the treatment of fractures were selected to find out the cases with the similar treatment objects and the same curative effect evaluation criteria for the comparative study.RESULTS AND CONCLUSION： The absorbable materials for the treatment of fractures have significant advantages, removed without second surgery, little injury to the surrounding tissues of the joint and joint itself, good histocompatibility and fewer complications, and it has become one of the development directions for the internal fixation of fractures.
