Bilateral PAX locking plate fixation in cat


Treatment of a highly comminuted humeral condylar fracture in a cat using bilateral PAX locking plate fixation

A cat was presented to Eastcott Referrals after being attacked by a dog. A bite wound to the elbow region had caused a highly comminuted fracture of the humeral condyle and distal shaft.

A computed tomography (CT) scan was performed to establish whether the articular component could be reconstructed.

Despite the catastrophic nature of the fracture it was possible to reconstruct the articular surface using a lag screw across the humeral condyle. The condyle was reattached to the shaft of the humerus using bilateral PAX locking plates. 12 weeks following surgery the cat had returned to normal activity and follow up radiographs showed complete healing of the fracture.
