Abstract

An orthopaedic device is disclosed for secure mechanical coupling to an elongated surgical rod. The device consists of a T-shaped member having a short, hollow, cylindrical sleeve portion and a threaded rod portion extending perpendicularly midway between the ends of the hollow sleeve portion. The hollow sleeve portion is adapted for slidable positioning over the cylindrical surface of the surgical rod. A narrow slot is provided through the center of the threaded rod portion, bisecting this rod portion, and through the wall of the hollow sleeve portion. The device further includes a block-shaped member having a central cylindrical bore extending between upper and lower surface and at least one U-shaped cutout extending from the middle of one side through the block into the central bore. A longitudinal slot extends between the upper and lower surfaces and from the front surface through the block into the central bore. The T-shaped member, with inserted surgical rod, is adapted for slidable engagement and capture within the cylindrical bore of the block-shaped member. A locking nut, threadably engaged with the bisected, threaded rod portion, applies a force upon the slotted sleeve member to clamp the cylindrical surface of the surgical rod while holding the T-shaped member and clamped surgical rod in a secure, locked position within the block-shaped member.
