Clinical Clues

  1. A young large-breed dog develops a persistent forelimb lameness that worsens after exercise.
  2. The owner reports a stiff gait when the dog first gets up from rest.
  3. Pain is localised to the proximal forelimb joint and the dog resents full flexion and extension.
  4. Mild periarticular effusion is present around the affected joint.
  5. Imaging reveals chronic degenerative change involving the medial compartment of the joint.
  6. Developmental disease of the canine elbow commonly causes forelimb lameness in young large-breed dogs.

Diagnosis

Canine Elbow Dysplasia

This case is most consistent with Canine Elbow Dysplasia because the dog has a young large-breed signalment, elbow pain, joint effusion, and degenerative elbow changes on imaging. The most important clues are the forelimb lameness and elbow-focused examination findings, which make a shoulder problem less likely.
