Transverse Sliding of the Median Nerve Beneath the Flexor RetinaculumFrom the Department of Orthopaedic Surgery, Torano-mon Hospital, Tokyo, Japan Correspondence: Ken-ichi Nakamichi, M.D., Department of Orthopaedic Surgery, Torano-mon Hospital, 2-2-2 Toranomon Minato-ku, Tokyo 105, Japan. Transverse sliding of the median nerve beneath the flexor retinaculum during active-resistant flexion of the fingers was sonographically demonstrated. Although it is a physiological phenomenon, it may cause mechanical nerve deformation in addition to longitudinal sliding when the nerve is subject to compression against the flexor retinaculum by tensed overlying flexor tendons.
