A young man present with incapacitating pain in his left shoulder.
His plan films and MRI show a small central area of avascular necrosis. No risk factors for AVN were identified.
At surgery the glenoid articular cartilage was intact. A central defect in the humeral head was seen
with a loose flap of cartilage
An anatomic hemiarthroplasty was performed under general anesthesia without a brachial plexus block using a canal-sparing smooth stemmed humeral component inserted with impaction autografting.
On the evening of surgery he had excellent comfortable range of motion.
Comment: While other options were considered, a robust anatomic hemiarthroplasty was selected to provide a durable return to high levels of activity.
