TI  - Radiologic Comparison of Humeral Position according to the Implant Designs 
      Following Reverse Shoulder Arthroplasty: Analysis between Medial Glenoid/Medial 
      Humerus, Lateral Glenoid/Medial Humerus, and Medial Glenoid/Lateral Humerus 
      Designs.

AB  - BACKGROUND: The currently available reverse shoulder arthroplasty (RSA) designs 
      can be classified into medial glenoid/medial humerus (MGMH), lateral 
      glenoid/medial humerus (LGMH), and medial glenoid/lateral humerus (MGLH) 
      prosthesis designs. The purpose of this study was to radiologically analyze the 
      effect of different RSA designs on humeral position following RSA. METHODS: A 
      total of 50 patients who underwent primary RSA were retrospectively analyzed. 
      Among 50 patients, 33 patients (group A: MGMH) underwent RSA with Aequalis system 
      (Wright, Inc, Bloomington, MN, USA), 6 (group B: LGMH) with Aequalis system using 
      bony increased offset, and 11 (group C: MGLH) with Aequalis Ascend Flex system. 
      The acromiohumeral distance, acromioepiphyseal distance (AED), lateral humeral 
      offset (LHO), LHO from the center of rotation (LHO(COR)), and deltoid length were 
      radiologically measured to quantify the distalization and lateralization of the 
      humerus. RESULTS: The increment in postoperative AED was 19.92 +/- 3.93 mm in group 
      A, 24.52 +/- 5.25 mm in group B, and 25.97 +/- 5.29 mm in group C, respectively 
      (p=0.001). The increment in postoperative LHO was 0.13 +/- 6.30 mm, 8.00 +/- 12.14 
      mm, and 7.42 +/- 6.88 mm, respectively (p=0.005). The increment in postoperative 
      LHO(COR) was 20.76 +/- 6.06 mm, 22.04 +/- 5.15 mm, and 28.11 +/- 4.14 mm, respectively 
      (p=0.002). CONCLUSIONS: The radiologic analysis of the effect of different RSA 
      designs on humeral position following RSA showed significant differences in the 
      increment in postoperative AED, LHO, and LHO(COR) between the 3 groups. 
      Therefore, MGLH design seems to be more effective for humeral distalization and 
      lateralization compared to original Grammont design.
