Table 6.
Postoperative complications for both types of shoulder replacements. Acromioclavicular joint (ACJ) pain is common among aTSR and rTSR, and can be resolved by injections or arthroscopic excision of the distal clavicle (EDC). The main complications for rTSR are stress fractures (#) of the acromion or the scapular spine. The category “Other” reports one case with an avulsion fracture of the triceps. Percentages (%) are based on total number of patients available at 2-year follow-up (aTSR n = 44; rTSR n =43).
