The triceps muscle flap for axillary contracture release

Area of Science:

• Orthopedic Surgery
• Plastic and Reconstructive Surgery

Background:

• The triceps muscle flap was previously an overlooked surgical technique.
• Reconstruction of the axilla often presents challenges, particularly after burn contractures.

Observation:

• The long head of the triceps muscle possesses a distinct proximal neurovascular supply.
• This allows for a rotational axis at the teres major muscle level.

Findings:

• A valid triceps muscle flap can be created using only the long head.
• This flap allows for anterior or posterior transposition as a local muscle flap.
• Necessary functional preservation can be achieved with this approach.

Implications:

• The triceps muscle flap serves a useful, albeit secondary, role in axillary reconstruction.
• This technique is particularly relevant for managing sequelae of burn contractures.
• It offers a new option for functional and aesthetic restoration in complex cases.
