fingerulnar

Fingerulnar is a descriptive term used in some anatomical and biomechanical writings to denote the functional and anatomical relationship between the fingers and the ulna of the forearm. It is not a standardized medical diagnosis, but a way to discuss how structures on the ulnar side of the forearm and hand—such as the distal ulna, ulnar-sided carpal joints, and related tendons and ligaments—contribute to finger movement and grip.

Anatomically, the ulna runs parallel to the radius in the forearm, with the distal ulna participating in the distal radioulnar joint and in the ulnocarpal articulation that supports the little and ring fingers. The ulnar side of the hand involves the joints and soft tissues that influence finger alignment and force transmission during hand movements.

Functionally, fingerulnar considerations emphasize how finger flexors and extrinsic tendons interact with ulna-related structures, and how forearm rotation or ulnar deviation can influence grip strength, precision, and finger alignment. The concept highlights the integrated nature of hand mechanics rather than viewing the fingers in isolation.

Clinically, the term may arise in discussions of ulnar-sided wrist pain, distal radioulnar joint instability, TFCC injuries, or tendon disorders, where the relationship between the fingers and ulna affects diagnosis, rehabilitation, or surgical planning. It is not a distinct condition, but awareness of fingerulnar mechanics can aid clinicians and researchers in understanding hand function and in guiding therapeutic interventions.
