Summary

This study on Dana unconstrained total shoulder arthroplasty found significant improvements in pain and function for patients with various shoulder conditions. While most patients benefited, some experienced complications requiring revision surgery.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Total shoulder arthroplasty (TSA) is a common procedure for debilitating shoulder conditions.
  • Unconstrained TSA designs aim to restore shoulder function and alleviate pain.
  • The Dana unconstrained TSA is one such implant used for diverse etiologies.

Purpose of the Study:

  • To evaluate the clinical outcomes and complication rates of the Dana unconstrained total shoulder arthroplasty.
  • To assess the efficacy of a hooded glenoid component in rotator cuff-deficient shoulders.

Main Methods:

  • Retrospective follow-up of 56 Dana unconstrained total shoulder arthroplasties in 47 patients.
  • Minimum two-year follow-up period.
  • Preoperative and postoperative assessment of pain, function, and range of motion.

Main Results:

  • Significant improvements in average pain (3 to 8) and function (3 to 7) ratings postoperatively.
  • Substantial gains in abduction and external rotation for osteoarthritis, rheumatoid arthritis, and osteonecrosis.
  • Hooded glenoid component improved pain and function in rotator cuff-deficient shoulders, but not range of motion.
  • Complication requiring revision occurred in 7 shoulders (5 regular, 2 hooded).
  • Radiolucency at the bone-cement interface was common (53 shoulders), but loosening was infrequent (2 revisions).

Conclusions:

  • The Dana unconstrained total shoulder arthroplasty demonstrates favorable outcomes in pain relief and functional improvement for a range of shoulder pathologies.
  • The hooded glenoid component offers a potential benefit for rotator cuff-deficient shoulders.
  • While radiolucency is common, it does not consistently lead to component loosening or revision surgery.
