Zusammenfassung

Magnetic Resonance Image (MRI) is recently reasonable widespread in veterinary medicine and veterinarians are increasing its use in canine shoulder disease. The objective of this job is to study shoulder joint of dogs through arthroscopy and Magnetic Resonance Image. In order to screen canine shoulder disease a protocol of Magnetic resonance was performed and proved in healthy dogs and dogs with shoulder disease. Magnetic resonance image were compared with arthroscopic findings. The 91.67% of dogs were 2-7 years, medium and large breed including crossbreed, German Sheppard, Retrievers, Great Dane, Boxer and water dogs. More frequently RMI diagnostic were 45.83% Supraspinatus Tendinopathy (ST), 20.83% Instability joint disease (IJD), 12.5% Bicipital Tenosynovitis (TSB) and Osteochondrosis Dissecans (OCD) of humeral head, and 4.16% Incomplete ossifications or caudal center of Glenoid Cavity (IOCCGC) and Infraspinatus muscle contracture (FIMC). More frequently diseases by arthroscopy were 41.66% IJD, 25% TSB and OCD and 4.16% IOCCGC and FIMC. Concordance between both techniques was 85.4%. Regarding to disease like Osteochondritis Dissecans and Incomplete Ossification of Caudal Glenoid cavity concordance was 100%, with regard to Shoulder Joint Instability was an 80% and Tenosynovitis of Biceps Tendon was a 66.66%. Inflammatory degree was overestimate in 14.6% of cases compared with arthroscopic findings. IRM revealed intra and extra articular disease, subcondral bone lesions and joint effusion. Arthroscopy allowed best assessment of synovial membrane and joint cartilage and to perform dynamic functional test. The affected tissues consistence was determined by palpation with arthroscopy instrumentation. Moreover arthroscopy allowed surgery treatment at the same time. MRI is a noninvasive technique that allowed a comprehensive assessment of the shoulder joint and is the best choice to diagnose canine shoulder diseases.
