A locking instrument assembly (10, 200, 400, 500) for use in conjunction with an intramedullary device (100) is disclosed. The locking instrument assembly (10, 200, 400, 500) includes an inner collet (12, 70, 212, 412, 512), an outer body (30, 80, 230, 430, 530), and a knob (60, 90, 260, 460, 560). The inner collet (12, 70, 212, 412, 512) has a collar (20, 79, 220, 420, 520) and a fastener member (22, 222, 422). The knob (60, 90, 260, 460, 560) engages the fastener member (22, 222, 422) to press the outer body (30, 80, 230, 430, 530) against the collar (20, 79, 220, 420, 520). As the knob (60, 90, 260, 460, 560) mates with the fastener member (22, 222, 422), the collar (20, 79, 220, 420, 520) applies a clamping force to the intramedullary device (100).

Instrument de verrouillage (10, 200, 400, 500) destiné à être utilisé conjointement avec un dispositif intra-médullaire (100). L'instrument de verrouillage (10, 200, 400, 500) comprend un collet intérieur (12, 70, 212, 412, 512), un corps extérieur (30, 80, 230, 430, 530), et un bouton (60, 90, 260, 460, 560). Le collet intérieur (12, 70, 212, 412, 512) a un collier (20, 79, 220, 420, 520) et un organe d~attache (22, 222, 422). Le bouton (60, 90, 260, 460, 560) engage l'organe d~attache (22, 222, 422) pour appuyer le corps extérieur (30, 80, 230, 430, 530) contre le collier (20, 79, 220, 420, 520). Quand le bouton (60, 90, 260, 460, 560) vient s'accoupler avec l'organe d~attache (22, 222, 422), le collier (20, 79, 220, 420, 520) exerce une force de serrage sur le dispositif intra-médullaire (100).
