Internet-based survey on diagnosis and treatment recommendations for medial shoulder syndrome and instability in dogs.

OBJECTIVE

The aim of this study was to document perceived frequency of medial shoulder syndrome and instability (MSS/MSI) among dogs, and preferred diagnostic and treatment options related to the condition, among American or European Colleges of Veterinary Surgeons (ACVS/ECVS) diplomates, American College of Veterinary Sports Medicine and Rehabilitation (ACVSMR) diplomates, and dual diplomates of ACVS/ECVS and ACVSMR (double-Boarded diplomates).

PROCEDURE

An invitation to complete an online survey was sent to diplomates email listservs.

RESULTS

The known response rate for the survey was 15.8% (160 of 1014 email addresses). There was a difference ( = 0.006) among groups in number of cases of MSS/MSI seen, with ACVS/ECVS diplomates and double-Boarded diplomates seeing 0 to 5 cases per year (80.7 and 72.7%, respectively) and ACVSMR diplomates (32% of total respondents) seeing 11 to 26+ cases annually. The majority of all respondents (56.4%) felt the likely cause of MSS/MSI to be chronic/repetitive strain. Diagnostically, most respondents (78%) relied on shoulder abduction angles; however, most felt it was a questionable or somewhat accurate diagnostic test. The ACVSMR diplomates (88%) relied on musculoskeletal ultrasound as their preferred diagnostic modality, compared to only 35% of ACVS/ECVS diplomates and 45% of double-Boarded diplomates. Preferred treatment was rehabilitation with surgery for unresponsive cases, as reported by 86.9% of all respondents. Preferred surgical treatment was prosthetic ligament reconstruction (62.7%).

CONCLUSION

Despite the low known response rate of this survey, there were significant differences among specialties regarding frequency of MSS/MSI cases seen per year and preferred diagnostic modalities. However, there were no differences among specialties regarding the suspected underlying causes of MSS/MSI and initial treatment strategies.
