The triceps-preserving approach for semiconstrained total elbow arthroplasty

Area of Science:

• Orthopedic Surgery
• Reconstructive Surgery
• Biomechanics

Background:

• Total elbow arthroplasty (TEA) effectively manages elbow pain and dysfunction.
• Common indications include inflammatory arthropathies and complex distal humeral fractures.
• Triceps insufficiency is a significant complication following TEA.

Purpose of the Study:

• To present a new surgical technique for TEA aimed at reducing triceps insufficiency.
• To describe a modified posterior approach that preserves triceps tendon integrity.
• To evaluate the potential benefits of this novel approach for elbow joint replacement.

Main Methods:

• A novel posterior surgical approach for TEA is detailed.
• The triceps brachii muscle is dissected solely from the medial aspect.
• The olecranon insertion of the triceps and lateral soft tissues are intentionally left undisturbed.

Main Results:

• The described technique aims to prevent triceps insufficiency by preserving its anatomical attachments.
• This approach may lead to improved postoperative elbow strength and function.
• The method allows for unimpeded access to the elbow joint while protecting critical structures.

Conclusions:

• The described medial-only triceps dissection represents a potentially safer technique for TEA.
• This approach may mitigate the risk of triceps insufficiency, a known complication of TEA.
• Further clinical studies are warranted to validate the efficacy and long-term outcomes of this technique.
