Correction of angular deformities caused by osteochondrosis using a tension band plate in a Siberian husky

Abstract

A 4-month-old intact male, Siberian husky dog, weighing 14.6 kg, was initially presented to the Gyeongsang National University Animal Medical Center (GAMC) with a history of bilateral forelimb lameness and angular deformity. Physical examination revealed forelimb lameness and valgus deformities. Radiography showed a conical shaped, radiolucent, thickened and irregular marginated distal growth plate in both distal ulnar physis. Thickening of distal growth plate also was evident at both the distal radial physis, and the presence of osteophytes was observed. A diagnosis of angular deformity was made on the basis of a shortened ulna associated with osteochondrosis. Temporary hemiepiphysiodesis was implemented by surgical insertion of tension band plate. The plates were implanted for 6 weeks. Pre- and post-operative radiographs of both forelimbs were evaluated to determine the angle of frontal plane alignment (FPA) and sagittal plane alignment (SPA) over a 8-week period. FPA was corrected into the normal range in the right forelimb, and SPA was close to the reference range in the both forelimbs. Furthemore, a reduction in osteochondrosis was revealed by radiography. This case report establishes that temporary hemiepiphysiodesis with a tension band plate should be option in dogs with angular deformities during a growing period and is minimally invasive with a lower morbidity than traditional osteotomy. Moreover, this treatment facilitates the resolution of osteochondrosis lesions.
