Arthroscopic-assisted stabilization of medial shoulder instability in a Miniature Poodle

Abstract

A 12-year old female miniature Poodle was presented because of a 4/4 right fore-limb lameness. The orthopedic examination demonstrated pain at palpation of the right shoulder and an abduction angle of 55 °. MRI examination confirmed injuries consistent with a traumatic medial shoulder instability with no evidence of shoulder dysplasia. A partial rupture of the subscapularis tendon and complete detachment of the cranial gleno- humeral ligament were confirmed with arthroscopy. The joint was successfully stabilized using an arthroscopic assisted prosthetic suture.

Medial Shoulder Instability: Prevalence and Treatment Outcomes in 17 Poodles and 31 Dogs of Other Breeds

“…Current described treatment options include both nonsurgical and surgical management (see ►Table 1). 6,7, 14,15,[17][18][19][20][21][22][23][24] Surgery aims to reconstruct medial stability via tendon augmentation or prosthesis implantation. There are variations in MGHL reconstruction techniques and implants, with the consistent aim to reconstruct the medial support for the glenohumeral joint, 14,15,[19][20][21][22]25 maintaining joint alignment and normal biomechanics.…”

Biceps and supraspinatus tendon transpositions have independently been shown to provide improved medial stability.…”
