文题释义:
锁定钢板:是一种带有螺纹孔的骨折固定装置,这些孔在带有螺纹头的螺钉拧入后,钢板就成为一种(螺钉)角度固定装置。可同时具有锁定和非锁定孔,以供不同螺钉拧入。任何能够拧入角度固定(稳定)的螺钉、栓的钢板实质上都是锁定钢板。钢板的固定是不依靠骨摩擦力来实现连接,而是完全依靠钢板自身的交锁结构来实现。钢板与骨头表面可以留有一定间隙,消除了钢板与骨重压接触的不良作用,极大改善了血运和骨膜的生长和恢复。与传统钢板的主要生物力学差异是后者依赖于骨-钢板界面的摩擦力来完成钢板对骨的加压。
锁定螺钉:为自攻螺钉,可以不用攻丝或骨钻;钢板与骨皮质间无加压力,对骨膜不产生压力,从而保护骨膜的血运;在手术技术上可以满足微创操作的要求,可以很好地保护骨折局部的血运,进而不需要植骨操作;内固定支架弹性固定,在载荷存在的情况下,骨折块间有应力刺激,这种刺激有利于骨痂形成,有利于骨折愈合。
 
摘要
背景:跟骨关节内粉碎性骨折的处理相当棘手,治疗不当常遗留足跟痛、创伤性关节炎及扁平足等后遗症,严重影响患肢功能。
目的:比较锁定钢板和普通钢板治疗跟骨关节内骨折的临床疗效。
方法:跟骨关节内骨折并接受切开复位钢板内固定手术患者76例,94足,根据钢板类型分为普通钢板内固定组和跟骨锁定钢板内固定组。比较2组观察骨折愈合时间、AOFAS评分、疼痛目测类比评分、Bohler角丢失角度及不良反应;并对2组骨质疏松患者bohler角丢失度数进行比较。
结果与结论:①两组患者内固定后骨折愈合时间、AOFAS评分、目测类比评分以差异均无显著性意义(P > 0.05);②跟骨影像学指标(Bohler角)的比较差异也无显著性意义(P > 0.05);③相对于普通钢板组,锁定钢板组骨质疏松患者的Bohler角丢失度数较小;④结果提示,锁定钢板与普通钢板治疗跟骨关节内骨折的各项临床指标和影像学指标没有显著差异。对于骨质疏松患者,锁定钢板在预防关节复位丢失方面具有一定优势,但是仍需要大样本的深入研究。

Abstract:

BACKGROUND: Comminuted intra-articular fractures of the calcaneus are difficult to treat, and inappropriate treatment will lead to some sequelae such as talalgia, traumatic arthritis and flatfoot, which do harm to functional recovery.

OBJECTIVE: To compare the clinical efficacy of locking and traditional plates for intra-articular calcaneal fractures
METHODS: Seventy-six patients (94 feet) with intra-articular calcaneal fractures were enrolled, and received open reduction and plate internal fixation. All patients were allotted to two groups based on the fixation materials, including locking plate and traditional plate groups. The healing time, AOFAS scores, Visual Analogue Scale scores, loss of Bohler angle and adverse events were compared between groups. In addition, the loss of Bohler angle of osteoporotic patients was compared between groups.
RESULTS AND CONCLUSION: There were no significant differences in the healing time, AOFAS scores, Visual Analogue Scale scores and Bohler angle between two groups after surgery (P > 0.05). But for osteoporotic patients, compared with the traditional plate group, the loss of Bohler angle was smaller in the locking plate group. These results suggest that the various clinical and radiographic indicators of locking plate and traditional plate for intra-articular calcaneal fractures show no significant differences. For osteoporotic patients, locking plate has certain advantages in preventing loss of joint reduction, but large-size trials are needed.
