<p>Apparatus for measuring bone depth for determining the length of fastener to be employed in medical treatment of the bone includes an elongated inner bone probe having a bone-engaging portion and a plurality of first manually-engageable elements secured thereto. An outer sleeve overlies at least a portion of the inner bone probe and is movable with respect thereto. A second manually-engageabl? element is secured to the outer sleeve. The first and second manually-engageable elements may be generally ring-shaped, so as to facilitate insertion of a user's fingers. The apparatus permits the bone-engaging portion of the inner bone probe to pass through an opening in the bone and engage the distal exterior surface in intimate contact as a result of the first manually-engageable elements being engaged and urged away from the bone.</p> |
