文题释义:
生物可吸收材料:在体内强度保持时间为10周-6个月,这正是松质骨愈合的时间,克服了AO内固定出现的应力遮挡的缺点,有利于骨折的愈合及踝关节的功能锻炼,避免了创伤性关节炎的发生,骨折愈合后生物可吸收材料在人体内降解为CO2与H2O,参与体内正常的新陈代谢,对机体无毒性反应,对骨折断端无明显影响。可吸收接骨螺钉在失去其强度的同时,应力逐渐转移至愈合的骨组织上,有利骨密度增加,不会导致位于内固定物下方的骨皮质弱化,减少了骨质疏松危险。
可吸收螺钉修复骨折的优点:①患者不需要做第二次金属内固定物去除手术。②可解决应力遮挡问题,避免骨质疏松。③无金属刺激及腐蚀反应。④允许骨折局部产生微动。⑤创面感染率低。⑥不干扰CT及MR的影像结果。
 
摘要
背景:传统踝关节骨折内固定修复中使用的材料多为金属螺钉或克氏针等,虽然可达到坚强内固定的目的,但均需二次手术取出。近年来,由于生物降解可吸收螺钉的弹性模量与松质骨相当,已作为金属螺钉替代物被广泛应用于临床。
目的比较可吸收螺钉与金属螺钉置入内固定修复踝关节骨折的生物相容性及踝关节功能恢复情况。
方法:选择踝关节骨折患者100例,其中男70例,女30例,年龄19-55岁,其中50例采用可吸收螺钉进行内固定修复,50例采用金属螺钉进行内固定修复。修复后随访观察两组临床疗效、踝关节Kofoed评分、骨折愈合时间及不良事件发生情况。
结果与结论:两组均随访6个月以上,骨痂生长良好,骨折端对位对线良好,未见骨延迟愈合或骨不愈合,可吸收螺钉组、金属螺钉组临床疗效优良率分别为96%、94%,组间比较差异无显著性意义;两组踝关节Kofoed评分、骨折愈合时间及不良事件发生率比较差异均无显著性意义(P > 0.05)。结果表明,可吸收螺钉置入内固定修复踝关节骨折的生物相容性良好,可有效恢复踝关节功能,其疗效与传统金属螺钉相似。

Abstract:

BACKGROUND: Previous ankle fracture surgery mainly uses the internal fixation materials such as metal screws or Kirschner wire, which can achieve a strong internal fixation, but all need to be taken out in the secondary surgery. In recent years, elastic modulus of biodegradable absorbable screw is identical to that of cancellous bone, and has been widely used in clinic. 

OBJECTIVE: To compare the biocompatibility and functional recovery of ankle joint in the repair of ankle fractures with absorbable screws and metal screws.
METHODS: 100 patients with ankle fractures were selected, including 70 males and 30 females, at the age of 19 to 55 years old. Fifty patients were repaired with absorbable screws and fifty patients were repaired with metal screws. Clinical efficacy, Kofoed score, fracture healing time and adverse events were observed between the two groups after repair.
RESULTS AND CONCLUSION: Patients were followed up for over 6 months in both groups, showing good bony callus, good contraposition and alignment at the fracture end. No delayed union or nonunion occurred. The excellent and good rate of clinical effect was 96% and 94% in the absorbable screw group and metal screw group, respectively, showing no significant difference. There was no significant difference in ankle Kofoed score, fracture healing time and incidence of adverse events between the two groups (P > 0.05). These results suggest that absorbable screw fixation for ankle fractures had good biocompatibility and could effectively restore ankle function; its effects are similar to that of traditional metal screws.
