A refresher on directional terminology for the hand: anterior = palmar, posterior = dorsal, medial = ulnar, lateral = radial. Bony projections from the pisiform (i), hamate (i), scaphoid (m), and trapezium (m) stick out ventrally on the palm (2 medial, 2 lateral) Between these projections extends a ligamentous band, the flexor retinaculum. This (cid:271)a(cid:374)d retai(cid:374)s the ha(cid:374)d"s e(cid:454)tri(cid:374)si(cid:272) fle(cid:454)or te(cid:374)do(cid:374)s agai(cid:374)st the (cid:449)rist: preventing them from popping out like taut bowstrings when the wrist is flexed. Together, the flexor retinaculum and carpal bones enclose a passageway the carpal tunnel.
