Humeral resurfacing and glenoiditis

Case contributed by Dr Domenico Nicoletti

Presentation

Pain and functional limitation with previous right humeral resurfacing for osteoarthritis.

Patient Data

Age: 60 years
Gender: Male
X-ray

Post-operative - 10 years prior to presentation

Humeral head resurfacing and biological resurfacing of the glenoid by meniscal allograft. Normal subacromial space and joint space between glenoid and humeral head.

X-ray

At presentation

Glenoid erosion with sclerosis of the glenoid surface.

Glenoid erosion with central sclerosis of the glenoid surface. There is a modest posterior subluxation of the humeral head due to insufficiency of the infraspinatus. Increase in the glenoid depth between postoperative radiography and final follow-up at 10 years.

Case Discussion

The humeral head surfacing prosthesis, devised by Copeland, allows maximum conservation of the bone stock and, with it, the morphological indices of the native proximal humerus.

Glenoiditis is the most frequent complication of cephalic implants with a stem and is characterized by an erosive process of glenoid cartilage. The clinical presentation is nonspecific, defined by pain and progressive joint limitation.

Cartilaginous wear in young patients is quite rapid, probably related to joint stress. The determining cause of glenoiditis is the increase of joint stress.
