可吸收内固定材料修复髌骨横断性骨折

摘要

BACKGROUND: In recent years, al kinds of absorbable internal fixation materials have been used in the clinical treatment of patel ar transverse fractures. OBJECTIVE: To investigate the repairing effect of absorbable internal fixation materials on patel ar transverse fractures. METHODS: Total y 102 cases of fresh patel ar transverse fractures were included 62 males and 40 females cases, with a mean age of (41.85±11.15) years, and according to treatment methods, they were divided into two groups: observation group (n=52) using absorbable screws for reconstruction and control group (n=50) using Kirschner wire repair. At 12 months after repair, Lysholm knee function score were measured and evaluated, and the occurrence of adverse events was recorded. RESULTS AND CONCLUSION: The knee function score and excel ent rate of the observation group were significantly higher than those of the control group (both P < 0.05). In the observation group, there were four cases of fracture displacement, but no skin irritation and other adverse events occurred; in the control group, there were two cases of nonunion and five cases of skin irritation or internal fixation loosening and slippage. Therefore, there was a higher incidence of adverse events in the control group compared with the observation group (P < 0.05). These experimental results show that the use of absorbable screws in the repair of patel ar transverse fracture can promote the functional recovery of the knee joint, with good biocompatibility.%背景：近几年来，各种可吸收内固定材料开始被积极应用于各种髌骨横断性骨折的临床治疗中。目的：探讨可吸收内固定材料修复髌骨横断性骨折的效果。方法：纳入102例新鲜髌骨横断性骨折患者，其中男62例，女40例，年龄(41.85±11.15)岁，按治疗方法分为2组，观察组(n=52)采用可吸收螺钉修复，对照组(n=50)采用改良张力带钢丝内固定修复。修复后12个月，进行 Lysholm 膝关节功能评分与评估，记录不良事件的发生情况。结果与结论：修复后12个月，观察组膝关节功能评分与优良率均高于对照组(P 均<0.05)，观察组有4例出现骨折移位，未出现内固定物对皮肤产生刺激等不良事件；对照组有2例出现骨折移位，5例出现内固定物对皮肤产生刺激或者内固定滑脱松动，对照组不良事件发生率高于观察组(P <0.05)。结果表明，利用可吸收螺钉修复髌骨横断性骨折，可促进膝关节功能恢复，并具有良好的生物相容性。
