title: Reversed shoulder arthroplasty in cuff tear arthritis, fracture sequelae, and revision arthroplasty.
abstract: OBJECTIVE
  Reversed shoulder arthroplasty may be used for severe arthropathy where conventional prostheses cannot restore the function sufficiently. We analyzed the medium-term results and potential complications of the reversed prostheses, and also the influence of etiology on the result. METHODS; 52 women and 7 men, average age 70 (60-82) years, were followed for mean 4 (2-7) years. The indications were cuff tear arthropathy (CTA) (23), fracture sequelae (20), and revision of a failed conventional arthroplasty (16).
  
  
  RESULTS
  The average Constant score improved from 18 (2-55) points to 59 (17-96) points. It rose from 26 to 74 points in patients with CTA, from 12 to 48 in those with fracture sequelae, and from 10 to 54 points in revision arthroplasty. We also found an overall improvement in active forward flexion from 47 degrees to 105 degrees , and in active abduction from 46 degrees to 93 degrees . Scapular notching was seen in 51 shoulders. Radiolucent lines below the base-plate were present in 2 cases. There were no instances of loosening. Revisions were necessary in 15 patients: 5 with infections (all had had prior surgery), 5 with hematoma, 3 with dislocations, and 2 with disconnections of the shaft components.
  
  
  CONCLUSIONS
  Reversed prosthetic replacement is a suitable method for restoring function and attaining pain relief in severe arthropathies. The results in revision arthroplasty are less predictable, with complications and revision rates higher than those in CTA patients. The reversed prosthesis should therefore only be used when conventional methods have failed.
