In dogs with medial shoulder instability, what treatment option results in the best patient outcomes medical vs. surgical management?
Clinical bottom line
Category of research question
The number and type of study designs reviewed
10 papers were critically reviewed. Whilst one study was prospective in nature, it was performed in research dogs that were then euthanised to evaluate outcome of various surgical procedures. Of the remaining nine papers reviewed, six were retrospective studies, two were case reports, and one was a combination of a cadaveric project with case report
Strength of evidence
Surgical and medical treatment of medial shoulder instability can be successful. There is no strong evidence to support one surgical treatment over another
Dogs diagnosed with medial shoulder instability may be treated successfully with either medical or surgical management
The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
