Summary
Bilateral shoulder arthroplasty using both total shoulder arthroplasty and reverse shoulder arthroplasty provides good outcomes. While total shoulder arthroplasty offers better range of motion, both procedures yield similar patient satisfaction and functional scores.
Area of Science:
- Orthopedic Surgery
- Arthroplasty
- Shoulder Reconstruction
Background:
- Anatomic total shoulder arthroplasty (aTSA) and reverse shoulder arthroplasty (RSA) outcomes are typically reported independently.
- Some patients require aTSA on one shoulder and RSA on the contralateral shoulder due to differing indications.
Purpose of the Study:
- To evaluate functional outcomes and patient satisfaction in patients undergoing sequential bilateral shoulder arthroplasty with a combination of aTSA and RSA.
Main Methods:
- A cohort of twelve patients who received sequential bilateral primary shoulder arthroplasty (aTSA on one side, RSA on the other) between 1992 and 2009 was analyzed.
- Postoperative outcomes were assessed at a minimum of 1 year using Constant score, American Shoulder and Elbow Surgeons (ASES) score, subjective shoulder value, and patient satisfaction.
Main Results:
- Mean Constant scores were 77 for aTSA and 73 for RSA (P=.2488).
- Mean ASES scores were 89.6 for aTSA and 82.4 for RSA (P=.0125).
- Greater external rotation (43° vs 12°) and internal rotation (T8 vs L1) were noted after aTSA (P<.0001 for both).
- Patient satisfaction was high (92%) for both types of arthroplasty, with similar subjective shoulder values (85.4% vs 82.5%; P=.6333).
Conclusions:
- Sequential bilateral shoulder arthroplasty combining aTSA and RSA can achieve favorable functional results and high patient satisfaction.
- While aTSA demonstrates superior range of motion, overall functional scores and patient-reported outcomes are comparable between the two procedures in this bilateral context.
