Objective— To report clinical findings and outcome in dogs diagnosed with medial shoulder instability (MSI) treated with radiofrequency-induced thermal capsulorrhaphy (RITC).
Study Design— Retrospective study.
Animals— Dogs (n=43) with MSI.
Methods— Medical records from consecutive cases with MSI based on orthopedic examination, palpation of shoulder abduction angles, and arthroscopic findings were used to determine clinical findings and long-term (≥1 year) outcome of RITC.
Results— Forty-three dogs met the criteria for inclusion; 2 dogs had bilateral MSI. The most common clinical findings were chronic unilateral weight-bearing lameness, large (>45°) shoulder abduction angles, and spinatus muscle atrophy in the affected limb. Mean preoperative abduction angle (50.7°±4.8°) in affected shoulders was significantly larger than in the unaffected shoulders (32.5°±2.1°). Mean postoperative abduction angle in affected shoulders was not significantly different from unaffected shoulders when measured immediately, 8, 16–20 weeks, and ∼1 year after surgery. Follow-up evaluation ranged from 1 to 6.2 years. RITC treatment resulted in improved clinical function in 40 cases (93%) with 34 cases (79%) considered excellent; 3 cases (7%) were considered failures.
Conclusions— RITC was a safe and effective method of treatment of MSI in most dogs studied.
Clinical Relevance— RITC can be considered as a viable option for surgical treatment of selected cases of MSI in dogs.
