Rocking horse loosening of a hybrid glenoid component

A patient presented one year after a total shoulder using a hybrid glenoid component

for glenohumeral arthritis

The postoperative films are shown below.

Over the next months the shoulder became weak, painful and anteriorly unstable, along with rocking horse loosening of the glenoid component.

Revision of this failed arthroplasty will be complicated by the glenoid bone deficiency, the need to remove the bone-ingrowth humeral component, and the fixed anterosuperior contracture.
