ABSTRACT
OBJECTIVE:
The objective of this study was to compare two four-strand techniques the traditional Strickland and cruciate techniques.METHODS:
Thirty-eight Achilles tendons were removed from 19 rabbits and were assigned to two groups based on suture technique (Group 1, Strickland suture; Group 2, cruciate repair). The sutured tendons were subjected to constant progressive distraction using a universal testing machine (Kratos®). Based on data from the instrument, which were synchronized with the visualized gap at the suture site and at the time of suture rupture, the following data were obtained maximum load to rupture, maximum deformation or gap, time elapsed until failure, and stiffness.RESULTS:
In the statistical analysis, the data were parametric and unpaired, and by Kolmogorov-Smirnov test, the sample distribution was normal. By Student's t-test, there was no significant difference in any of the data the cruciate repair sutures had slightly better mean stiffness, and the Strickland sutures had longer time-elapsed suture ruptures and higher average maximum deformation.CONCLUSIONS:
The cruciate and Strickland techniques for flexor tendon sutures have similar mechanical characteristics in vitro. .Palavras-chave
