Lateralized glenospheres in reverse shoulder arthroplasty (RSA) did not improve pain or range of motion, but significantly reduced scapular notching. This study evaluated the isolated effect of glenosphere lateralization in RSA.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Musculoskeletal Research

Background:

  • Lateralization of the glenohumeral center of rotation in reverse shoulder arthroplasty (RSA) may improve rotator cuff tension and reduce impingement.
  • Few studies have isolated the clinical effect of glenoid lateralization in RSA.

Purpose of the Study:

  • To evaluate if isolated glenosphere lateralization in RSA impacts clinical outcomes using a single implant design.
  • To compare outcomes between RSA with a lateralized glenosphere and standard glenospheres.

Main Methods:

  • Retrospective review of 204 primary RSAs (2011-2018) using a single implant system.
  • Comparison of 102 cases with a +4mm lateralized glenosphere to 102 matched controls with standard glenospheres.
  • Analysis of range of motion (ROM), patient-reported outcome scores (ASESS, Constant, UCLA, SST, SPADI), and VAS pain scores with a minimum two-year follow-up.

Main Results:

  • Both groups showed significant improvements in ROM and outcome scores exceeding the minimal clinically important difference (MCID) and substantial clinical benefit (SCB).
  • No significant differences were found in postoperative pain, ROM, or overall outcome scores between the lateralized and standard glenosphere groups.
  • The lateralized glenosphere group had significantly lower rates of scapular notching (2% vs. 9%, p=0.03).

Conclusions:

  • Isolated +4mm glenosphere lateralization in RSA did not offer significant advantages in postoperative pain, ROM, or functional outcome scores.
  • Lateralized glenospheres in RSA demonstrated a significant reduction in scapular notching compared to standard glenospheres.
  • Further research may explore optimal glenosphere positioning for improved RSA outcomes.
