Abstract

Six surgical corrections were performed with techniques of bone and soft tissue reconstruction, according to the individual presentation of each patient, in four Toy breed dogs, which had grades III and IV luxation, two of them bilaterally operated. During the recovery excessive medial tension associated to the Sartorius muscle was detected, which motivated its release at the iliac insertion. The animals had a functional recovery of the limb after 15 days, and complications or loss of function related to the release of the Sartorius muscle were not observed even after six months. It is believed that the proximal disinsertion of this muscle can be necessary and effective in some patients as a complementary technique to release medial tension in dogs with grades III and IV medial patellar luxation.

Highlights

Apesar de Wangdee et al (2006) citar que a alteração do músculo sartório é acompanhada de hipertrofia de fibras individuais, diferentes tamanhos de fibras musculares, degeneração de Zenker, infiltração com fibras de colágeno e espessamento da bainha conjuntiva, não foi realizado exame por biópsia destes pacientes, por tratar-se de casos clínicos em que se tinha o objetivo de causar o menor trauma possível, mas a tensão existente no músculo, mesmo já tendo sido efetuados todos os outros procedimentos cirúrgicos de liberação da patela, era palpável e correspondia às observações clínicas citadas por esses autores

Summary

Introduction

Desinserção proximal do músculo sartório na correção da luxação patelar medial graus III e IV, em cães O objetivo deste relato foi descrever uma nova técnica complementar, baseada na desinserção proximal do músculo sartório, para reduzir a tensão patelar medial em cães com luxação de graus III e IV.
