Thermographic and histological analysis of rabbit different tenorrhaphies techniques (4 and 6 strands) after early active mobilization

Análise termográfica e histológica de diferentes técnicas de tenorrafias (4 e 6 passadas) em coelhos após a mobilização ativa precoce

Introduction

This research is based on the results of the surgeries of tenorraphy, which have been improved due to the association between strong and not voluminous sutures and physiotherapic protocols, which preconize the early active motion to the postoperative period.

Objective

To evaluate the healing process in vivo in different types of tenorraphies.

Methods

Thirty-six rabbits that underwent early active motion after tenorraphy. The sample was constituted of 3 groups of 12, in accordance with the 3 different types of suture (Brasil, Indiana and Tsai).

Results

On the 15^th and 30^th days after the surgery, thermographic and histological analyses revealed similar results that all groups showed similar behaviors in the same time of surgical repair, just differentiating between the periods. On the 30^th day analysis were observed that collagen fibers being more exuberant thickening, thus being able to offer higher tensile strength to the tendon.

Conclusion

That suggests early active motion may be increased gradually to around the 30^th day taking this as clinical relevance.
