ABSTRACT
The extensor carpi radialis longus (ECRL) and brevis (ECRB) muscles play a fundamental role in the extension and abduction of the wrist. Although isolated anatomical deviations are documented, the literature currently lacks a cohesive classification system and a comprehensive analysis of the collective clinical significance of these variations. A precise anatomical dissection was conducted on the right upper extremity of a cadaveric specimen. The study focused on identifying the morphological and tendinous arrangements of the radial extensor group. Investigations uncovered a rare structural anomaly consisting of a distinct inter-tendinous bridge linking the ECRL and ECRB tendons. Reporting these inter-tendinous connections is vital for medical literature. Identifying such anatomical diversity is essential for clinicians to ensure diagnostic precision, optimize preoperative planning, and improve surgical results in orthopaedic and musculoskeletal interventions.
