      for Favard Type-E1, E2, and E3 Glenoids.

AB  - BACKGROUND: Uncorrected superior glenoid wear in patients managed with reverse 
      total shoulder arthroplasty (rTSA) can result in increased complications, 
      including baseplate failure. The present study quantifies the clinical and 
      radiographic outcomes of patients with Favard type-E1, E2, and E3 glenoid 
      deformity who were managed with rTSA with use of a superior or superior/posterior 
      augmented glenoid baseplate. METHODS: We retrospectively reviewed the records for 
      68 patients with shoulder arthritis and Favard type-E1, E2, or E3 glenoid 
      deformity who were managed with primary rTSA and a 10 degrees  superior augmented or 10 degrees  
      superior/8 degrees  posterior augmented baseplate. The mean duration of follow-up was 40 
      months (range, 24 to 85 months). Outcomes were assessed preoperatively and at the 
      latest follow-up with shoulder range of motion and use of outcome scores 
      including the Simple Shoulder Test (SST), University of California Los Angeles 
      (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, Constant score, 
      and Shoulder Pain and Disability Index (SPADI) score. Radiographs were evaluated 
      preoperatively and at the time of the latest follow-up. Differences in 
      preoperative and postoperative range of motion and outcome metrics were assessed 
      with use of a 2-tailed Student t test. RESULTS: The majority of patients 
      experienced clinically meaningful improvements in terms of pain and function 
      following rTSA with a superior or superior/posterior augment, with 94% of 
      patients rating themselves as "much better" (73.5%) or "better" (20.5%) at the 
      time of the latest follow-up. At least 88% of the patients exceeded the minimum 
      clinically important difference (MCID) threshold, and 75% of patients exceeded 
      the substantial clinical benefit (SCB) threshold, for each of the clinical 
      outcome metrics and range of motion. Five complications were reported 
      (prevalence, 7.4%), including acromial stress fracture (2 patients), 
      posttraumatic scapular neck fracture (1 patient), chronic shoulder pain (1 
      patient), and aseptic glenoid loosening (1 patient). CONCLUSIONS: The present 
      short-term clinical and radiographic study demonstrated that shoulder arthropathy 
      with superior glenoid wear patterns (Favard types E1, E2, and E3) can be 
      successfully treated with rTSA with a superior or superior/posterior augmented 
      baseplate. Longer-term clinical and radiographic follow-up is necessary to 
      confirm that these promising short-term results are durable. LEVEL OF EVIDENCE: 
      Therapeutic Level IV. See Instructions for Authors for a complete description of 
      levels of evidence.
