Shoulder synovectomy

Area of Science:

• Orthopedic Surgery
• Rheumatology
• Medical Technology

Background:

• Rheumatoid arthritis commonly affects the shoulder joint, causing significant pain and functional limitation.
• Synovectomy, a surgical procedure to remove the inflamed synovial membrane, has been utilized to manage shoulder joint involvement in rheumatoid arthritis.
• Evaluating the long-term efficacy of shoulder synovectomy is crucial for treatment planning.

Purpose of the Study:

• To describe the technique and evaluate the long-term results of shoulder joint synovectomy in patients with rheumatoid arthritis.
• To compare the outcomes of an original surgical approach with a modified, simpler technique.

Main Methods:

• The study describes an original synovectomy technique involving acromion resection and rotator cuff splitting.
• A modified Neer approach, without acromion resection, was adopted in 1981 for both synovectomy and prosthetic replacement.
• Follow-up data was collected over a mean period of 5.3 years (range: 1-16 years) for 54 shoulders.

Main Results:

• The modified Neer approach resulted in easier postoperative management with equally good outcomes compared to the original method.
• Only 6 out of 54 shoulders required a total replacement prosthesis later, indicating the durable efficacy of synovectomy.
• The best results were observed in patients who underwent the procedure in the early stages of the disease.

Conclusions:

• Shoulder synovectomy is a valuable treatment for rheumatoid arthritis, providing lasting relief and preserving joint function.
• The simpler Neer approach offers advantages in postoperative management without compromising results.
• Clinical findings, rather than radiographic changes, should guide the indication for synovectomy, emphasizing the need for specialized training.
