Summary
Cementless stem reverse shoulder arthroplasty (RSA) shows improved mid-term functional outcomes for degenerative shoulder conditions. While stress-shielding was noted, it did not negatively impact clinical results.
Area of Science:
- Orthopedic Surgery
- Biomaterials Engineering
Background:
- Reverse shoulder arthroplasty (RSA) is a key treatment for degenerative shoulder conditions.
- Cementless stems are increasingly utilized in RSA procedures.
Purpose of the Study:
- To evaluate the mid-term functional outcomes of cementless stems in RSA.
- To assess complication rates associated with cementless stem RSA.
Main Methods:
- Retrospective review of 40 cementless RSA cases from January 2016 to December 2020.
- Clinical outcomes assessed via VAS, UCLA, Constant scores, and Range of Motion (ROM).
- Radiographic analysis included calcar and canal filling ratios.
Main Results:
- Significant improvements in VAS, UCLA, and Constant scores at 39-month follow-up (p<0.014).
- Enhanced ROM, including active anterior elevation (80° to 141.2°), abduction (71° to 132.2°), and external rotation (5.8° to 19.7°).
- Overall complication rate was 22.5%, with stress-shielding observed but without clinical impact.
Conclusions:
- Cementless stems provide favorable mid-term functional outcomes in RSA for degenerative conditions.
- Stems demonstrated appropriate alignment and canal filling ratios.
- Observed stress-shielding did not compromise clinical results.
