Osteomyelitis after cranial cruciate ligament rupture osteotomies in dogs / Infecção óssea após osteotomia para tratamento da ruptura de ligamento cruzado em cães

ABSTRACT

Background: Nowadays, many different techniques have been used to treat cranial cruciate ligament rupture (CrCL) in dogs, being the most common ones the tibial tuberosity advancement (TTA) and the tibial plateau leveling osteotomy (TPLO). These procedures promote dynamic stabilization. In other words, they try to stabilize the knee while supporting the limb, decreasing the cranial tibial impulse, which anticipates the functions return. Among the complications observed in these kind of osteotomy, stand out the osteomyelitis, with 7,3% requency in TPLO and 6,6% in TTA. In these cases, it is necessary to remove all the implants. Most bone infections are from bacterial source, mostly caused by Staphylococcus genus. The aim of this study was to describe 14 cases of osteomyelitis in dogs after CrCL rupture corrective osteotomy. Materials, Methods & Results: This retrospective study evaluated 89 dogs (104 knees) that had undergone any of the CCLR corrective osteotomy during the period of January 2006 to November 2012. These patients were divided in TTA (n = 56), TPLO (n = 36) or CWO (closing wedge osteotomy) (n = 12). Among the 104 knees, 14 developed osteomyelitis as postoperative complication, requiring the removal of the implants. The clinical signs observed in these patients were claudication (different degrees), pain in the area of the implants, swelling and local temperatur

RESUMO

Diversas técnicas de osteotomia têm sido empregadas para tratamento da ruptura de ligamento cruzado cranial (RLCCr) em cães, sendo as mais utilizadas, atualmente, TTA (tibial tuberosity advancement - avanço da tuberosidade tibial) e TPLO (tibial plateau leveling osteotomy - osteotomia de nivelamento do platô tibial). Estes procedimentos promovem estabilização dinâmica, ou seja, estabilizam o joelho durante o apoio do membro diminuindo o impulso tibial cranial e permitindo retorno precoce à função. [...]
