41-year-old male. Pain. Evaluate left shoulder/Dr Shi protocol. Four views of the left shoulder show moderate to severe osteoarthritis of the glenohumeral joint. There is slight posterior subluxation of the humeral head relative to the glenoid on the axillary view. Of note, the posterior glenoid appeared hypoplastic on the prior MRI. Mild to moderate osteoarthritis affects the acromioclavicular joint.
Osteoarthritis, as above.
