Abstract: | The skeletal architecture of the DRUJ provides minimal inherent stability, as the sigmoid notch is shallow and its radius
of curvature is 50% greater than that of the ulnar head Af Ekenstam F, Hagert CG. Anatomical studies on the geometry and
stability of the distal radio ulnar joint. Scand J Plast Reconstr Surg 1985;19(1):17–25]. Due to its incongruent articulation,
the DRUJ relies strongly on the surrounding soft tissues for stability. The triangular fibrocartilage complex (TFCC) is generally
accepted as the major soft tissue stabilizer of the DRUJ of which the volar and dorsal radioulnar ligaments are the primary
components. Restoration of the radioulnar ligaments offers the best possibility to restore the normal DRUJ primary constraints
and kinematics. This article presents an update of the procedure developed by the senior author that anatomically reconstructs
the palmar and dorsal radioulnar ligaments at their anatomic origins and insertions. |
