Positioning Dorsal recumbency Use sandbags/foam wedges or a cradle under the hips/pelvis to keep dog straight Turn head away from affected limb Extend limb cranially and tie Centre over the shoulder joint Collimate to show proximal 1/3rd humerus and include the scapula Ensure L/R marker in primary beam
What to look for Humeral head should be central in relationship to the supraglenoid tubercle Shoulder joint should not overlie the ribs
Top tips If measuring humerus ensure it is parallel to the X-ray cassette, and ensure your calibration tool is at the same distance from the cassette as the bone.
