Flexor carpi ulnaris (humeral head) muscle flap for reconstruction of distal forelimb injuries in two dogs.

Objective: To describe the use of the humeral head of the flexor carpi ulnaris muscle as a rotational flap for reconstruction of distal antebrachial, carpal, and metacarpal injuries in two dogs.

Study Design: Description of clinical cases.

Results: Local rotation of the humeral head of the flexor carpi ulnaris muscle provided coverage of the carpal and carpometacarpal bones and joint structures exposed by soft tissue avulsion.

Conclusions: The distal portion of the humeral head of the flexor carpi ulnaris muscle can be used as a local muscle flap.

Clinical Relevance: Early soft tissue coverage of large wounds to the carpal and metacarpal regions can be accomplished without resorting to a more technically difficult procedure, such as a free vascularized flap transfer.
