Técnica para fixação da tuberosidade tibial com fio metálico, após osteotomia e transposição

Abstract

The current technique sought to implement improvements in the method of attachment of the tibial tuberosity to its receptor bed, generating minor postoperative complications secondary to the procedure of reduction of patellar dislocation with transposition of the tibial crest. The objective of this study is to describe and validate an alternative for this technique, based on clinical results obtained with the prospective evaluation of the patients. The applied technique consists of the lateral or medial transposition of the tibial tuberosity, fixed with cerclage wire, through the creation of holes, both in the tibial tuberosity and in the receptor bed. Surgical wires were applied and fixed using isolated colchoeiro pattern. The technique was used in six dogs diagnosed with grade III or IV patellar dislocation, uni or bilaterally, with angular alterations in the involved pelvic limb. Eight procedures were totalized, animals were evaluated previously and at 10, 45 and 90 days after the surgical procedure. Among the 6 dogs submitted to the procedure, only 1 (16.6%) presented recurrence of patellar dislocation. The stabilization method was effective, providing bone consolidation at 45 days visible to the x-ray and showed no complication rates with the implant.
