Scapular luxation in a ferret (Mustela putorius furo)

Background

Scapular luxation is a rare condition observed in dogs and cats. It occurs following disruption of the muscles attaching the scapula to the thoracic wall (trapezius, rhomboideus, and serratus ventralis muscles) leading to dorsal displacement of the scapula. Surgical stabilization requires reattachment of the affected muscle and fixation of the scapula to the thoracic wall. Sutures are passed around a rib and through holes made on the dorsal margin of the scapula to secure the scapula on the thoracic wall. This technique is reported to result in a good to excellent outcome.

Case description

A scapular luxation was diagnosed in a ferret (Mustela putorius furo) presenting with a 180° internal rotation of the right scapula and associated forelimb following rupture of the serratus ventralis muscle. The scapula was not dorsally displaced on the thoracic wall. Following orthopaedic reduction, the luxation was surgically stabilized as described in the dog and cat. The functional result was excellent with persistent resolution of lameness during the 5-month follow-up period.

Conclusions

Surgical correction of a scapular luxation in a ferret led to an excellent outcome.

Significant relevance

Scapular luxation should be included in the differential diagnosis of forelimb lameness in the ferret. Surgical correction is feasible and may result in an excellent long-term outcome.
