We evaluated tendon holding capacities of suture materials that are commonly used in repair of Achilles tendon ruptures.
Achilles tendons of 60 sheep were removed by incisions 2-cm proximal to the calcaneal insertion and 1-cm distal to the musculotendinous junction. The tendons were randomly divided into six groups and sutures were placed with the Kessler technique at the distal end of the tendons using one of the following suture materials: 2 polydioxanone (PDS), 1 PDS, 2 Vicryl, 1 Vicryl, 2 Ethibond, and 1 Prolene. The distal end of the suture material was left free. Each specimen was mounted in an Instron machine, with the tendon being placed proximally and the suture material distally. The system was loaded with a displacement rate of 20 mm/min.
Failure of all the specimens was due to pull-out of the suture material through the tendon. There were no failures due to suture breakage. The highest and the lowest tendon holding capacities were found with 2 PDS and 2 Ethibond sutures, respectively.
Following Achilles tendon repair, the healing period, in particular the first three weeks, is precarious for pull-out of the suture material through the tendon. Thus, tendon holding capacity of the suture material is an important factor for the strength of the repair. Among the tested suture materials, 2 PDS was found to have the highest tendon holding capacity.
我们评估了常用于跟腱断裂修复的缝合材料的肌腱固定能力。
通过在跟骨附着点近端2厘米和肌腱结合部远端1厘米处做切口,切除60只绵羊的跟腱。将肌腱随机分为六组,使用以下缝合材料之一,采用凯斯勒技术在肌腱远端进行缝合:2号聚二氧六环酮(PDS)、1号PDS、2号薇乔、1号薇乔、2号爱惜邦和1号普理灵。缝合材料的远端保持游离。每个标本安装在一台英斯特朗材料试验机上,肌腱近端放置,缝合材料远端放置。系统以20毫米/分钟的位移速率加载。
所有标本的失效均是由于缝合材料从肌腱中拔出。没有因缝合线断裂而导致的失效情况。分别发现2号PDS和2号爱惜邦缝合线的肌腱固定能力最高和最低。
跟腱修复后,尤其是前三周,愈合期对于缝合材料从肌腱中拔出来说很不稳定。因此,缝合材料的肌腱固定能力是修复强度的一个重要因素。在所测试的缝合材料中,发现2号PDS具有最高的肌腱固定能力。
