Temporary transarticular stabilization with locking compression plate for the treatment of traumatic glenohumeral luxation in 10 dogs.

OBJECTIVE

The aim of this study was to describe the surgical technique, and the short to medium clinical outcome of dogs treated with temporary glenohumeral joint (GHJ) stabilization following traumatic luxation.

STUDY

DESIGN

Short case series.

METHODS

Medical records of dogs presented with GHJ luxation and treated with a temporary transarticular locking compression plate and screws were reviewed. Signalment, clinical signs, direction and duration of the luxation, diagnostic imaging, operative technique, complications and clinical outcome were reviewed. Liverpool Osteoarthritis in Dogs (LOAD) and Canine Orthopedic Index (COI) questionnaires were completed by the owners at 6 months after implant removal.

RESULTS

Clinical and radiographic findings were documented for 10 client-owned dogs at a mean follow-up of 42.5 days when implants were removed through a minimally invasive procedure. Two dogs exhibited minor complications identified through radiographs performed at the follow-up appointment consisting of screw loosening or breakage. These did not affect the clinical outcome. Temporary GHJ stabilization resulted in return stability and range of motion for all dogs. At 6 months 9/10 dogs returned to complete function while one died for other causes. In one case, luxation recurred 8 months postoperatively for which the dog underwent glenohumeral joint arthrodesis.

CONCLUSION

Temporary transarticular GHJ stabilization is a possible treatment option in cases of traumatic glenohumeral joint luxation. Further studies are required to determine the minimum immobilization time necessary to achieve joint stability, to assess the long-term complication rate and the possible risks associated with this technique in a controlled population.
