Following pseudoarthrosis of a 4-part fracture of the surgical neck of the humerus, a 60-year-old woman had been operated with a Neer II hemiarthroplasty through a deltopectoral approach. At 66 years old, she was referred to the senior author (AHK) because of consistent pain and limited range of motion (ROM) of her right shoulder. The radiographs revealed erosion of the posterior part of the glenoid, but there was no obvious misalignment of the prosthesis, nor any signs of loosening (Figure 1). Poor external rotation (–40°) and limited flexion/abduction (30°) led to the suspicion of poor soft-tissue balancing, with contracture and tightening of the anterior capsule and shortening of the subscapular tendon. To correct this, revision with a total arthroplasty was planned. The problem turned out to be of a different kind.
