Key points
-
Three main types of shoulder arthroplasty may be encountered, each corresponding to specific clinical situations: reverse shoulder arthroplasty, total shoulder arthroplasty, and partial shoulder joint replacement.
-
Shared complications by all types of shoulder prosthesis are fortunately rare but must imperatively be recognized early to initiate prompt and specific treatment.
-
Glenoid component loosening is the most frequent complication of total shoulder arthroplasty.
-
The most common complication after reverse shoulder arthroplasty is instability, ordinarily in an anterosuperior direction.
-
Progressive wear of the native glenoid is the sole complication of partial shoulder joint replacement.
