Neer Series II total shoulder arthroplasty provides excellent pain relief and improved range of motion (ROM). Outcomes may depend on the underlying disease and rotator cuff status.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Total shoulder arthroplasty is a common procedure for debilitating shoulder conditions.
  • The Neer Series II prosthesis is a widely used implant for shoulder replacement.

Purpose of the Study:

  • To evaluate the outcomes of Neer Series II total shoulder arthroplasty.
  • To assess pain relief, range of motion, and complications associated with the procedure.

Main Methods:

  • Seventy Neer Series II total shoulder arthroplasties were performed in 65 patients.
  • Average follow-up was 40 months.
  • Patients diagnosed with rheumatoid arthritis or osteoarthritis were included.

Main Results:

  • Excellent pain relief was achieved in all patients.

  • Average increase in range of motion was 60 degrees active forward elevation and 18 degrees external rotation.
  • Two glenoid components required revision due to progressive radiolucency, both in rheumatoid arthritis patients.

    • Conclusions:

    • Neer Series II total shoulder arthroplasty offers significant pain relief and functional improvement.
    • Osteoarthritis patients showed a statistically significant improvement in range of motion compared to rheumatoid arthritis patients.
    • Etiology and rotator cuff status may influence long-term outcomes.
