Abstract

Reverse total shoulder arthroplasty is one of the methods of surgical treatment for cuff tear arthropathy. Reverse total shoulder arthroplasty is increasingly being performed, but various complications have been reported. We experienced a case of acromion fracture after reverse total shoulder arthroplasty, which is quite a rare complication. So we report on this case along with reviewing the relevant literature.

Keywords: acromion, acromion fracture, stress fracture, reverse total shoulder arthroplasty

Figures and Tables

Figure 1

(A) The anteroposterior radiograph of the right shoulder shows degerative change and collapse of the humeral head. (B) MR-arthrogram of the patient shows massive full thickness rotator cuff tear of supraspinatus tendon and infraspinatus tendon.

Figure 2

Immediate post-operative radiograph.

Figure 3

The radiograph taken 4 months after surgery shows acromial fatigue fracture.

Figure 4

The anteroposterior radiograph taken 9 months after surgery shows bony union but acromial fragment is tilted inferiorly.
