Abstract
A 10-year-old intact female Chihuahua weighing 2 kg was presented for complaint of forelimb lameness with non-weight bearing posture. Greater tubercle was palpated medial to its normal location on palpation and crepitation was intermittent with manipulation. On radiographic examination, left medial scapulohumeral joint luxation was found. Bilateral medial patellar luxations also were found and evaluated as grade III. Surgically, the medial scapulohumeral joint luxation was reduced with transposition of the tendon of the biceps brachii muscle. The patient's gait became normal and non-weight bearing posture was resolved at 6 weeks postoperatively.
10살령의 2 kg의 암컷 치와와가 다리를 딛지 못하는 전지파행으로 내원하였다. 촉진시 대결절은 정상 위치 보다 내측에서 촉진되었고 염발음이 간헐적으로 들렸다. 방사선학적 검사에서 좌측 내측 견갑상완 관절 탈구로 진단되었다. 또한, 양측성으로 3기의 내측 슬개골 탈구도 관찰되었다. 외과적으로, 내측 견관절 탈구를 상완이두건 전위술로 정복하였다. 환견은 수술 6주째 정상 보행이었고 다리를 딛게 되었다.
