Revision total elbow replacement

Area of Science:

• Orthopedic Surgery
• Reconstructive Surgery
• Arthroplasty

Background:

• Total elbow replacement (TER) is indicated for complex distal humeral fractures, post-traumatic arthropathy, and inflammatory arthritis.
• Revision total elbow replacement (RTER) patients often have comorbidities and existing musculoskeletal dysfunction.
• Challenges in RTER include compromised soft tissue envelopes, making infection difficult to eradicate, especially in immunocompromised patients.

Purpose of the Study:

• To outline the specific challenges and considerations for revision total elbow replacement.
• To highlight the importance of managing bone stock, extensor mechanism, and ulnar nerve integrity.
• To emphasize the need for specialized surgical skills and individualized rehabilitation protocols.

Main Methods:

• Review of general and specific adverse events in total elbow arthroplasty.
• Analysis of challenges in RTER: bone stock loss, extensor mechanism insufficiency, and ulnar nerve management.
• Consideration of patient factors: comorbidities, previous surgeries, and soft tissue condition.

Main Results:

• RTER faces unique difficulties due to loss of humeral and ulnar bone stock.
• Restoring extensor mechanism continuity and function is critical for elbow motion strength.
• Ulnar nerve management is a frequent concern, particularly in revisions for fractures or post-traumatic conditions.

Conclusions:

• Revision total elbow replacement is a complex procedure demanding extensive surgical experience.
• Successful RTER requires proficiency in bone stock restoration, prosthetic implantation, and soft tissue management.
• Individualized rehabilitation is essential for optimizing functional recovery after revision total elbow replacement.
