Abstract: A spinal screw or hook has a slotted head to receive a support rod. A two-piece rod retainer is provided with an outer ring-like collar locked into the interior of the slotted head and a fastener extending through the collar to contact a support rod in the bottom of the slot.

Abstract: Surgical forceps have connecting members onto which working ends are attached in offset fashion, so that they can work together outside the plane of the forceps. One of the working ends is tubular and the other has an angled, U-shaped cross section which receives a portion of the tubular working end. With the tubular working end slipped over a pedicle screw attached to a vertebrae and the other end attached to a support rod, the vertebra can be brought to the support simply and expeditiously.

Abstract: This hook serves to treat vertebral column deformities. It is comprised of a shaft portion (2) with a longitudinal axis (1) to which a longitudinal support rod (5) can be attached transversely to the longitudinal axis (1), as well as a hook body (3) with a convex posterior side (34) and a concave anterior side (35) bent away from the longitudinal axis (1) connecting to the shaft portion (2). It is provided with a penetrating drill hole (36) extending from the convex posterior side (34) to the concave anterior side (35), to accept a screw (4).

Abstract: The osteosynthetic fixation element (10) in the form of a pedicular screw or a vertebral column hook has a lower section (2) that can be anchored into a bone and an upper section (3) connected in the direction of its longitudinal axis (1), that is completely penetrated transversely by a penetration channel (8) running transversely to the longitudinal axis (1) for acceptance of a longitudinal support (40). The upper section (3) is provided with an internal threading (5) and an external threading (9) to accept a locking part (30; 50) locking the longitudinal support (40). The upper section (3) is provided at its upper end (6) or at the inserted lock part (30; 50) with a rotationally-stable, releasable connecting mechanism (4, 5, 7; 11, 12) for positive and non-positive temporary acceptance of a manipulation device (20).

Abstract: An osteosynthetic fastening device, preferably in the form of a pedicle screw or a spinal column hook, has a channel in its upper section for receiving a support rod and a retaining element which clamps the rod in the socket through a spherical contact element.

Abstract: An osteosynthetic fixation device consists of a fixation element 1 which has a conical head section 11 and an anchoring element 12 abutting it which is for attachment into the bone. The fixation device also consists of a spherically formed, layered, slotted clamping piece 2 which has a conical borehole 21 for installation of the conical head section 11, and which is meant for locking within a connecting piece 3 equipped with a spherically shaped layered borehole 31. Fixation piece 1 has an axially arrayed tension element 4, permitting axial displacement and wedging of conical head section 11 in the borehole 21 that corresponds with it. The fixation device is appropriate for use as a plate/screw system, an internal or external fixator, and in particular for spinal column fixation.

Abstract: A clamp connection serves to connect two construction components, in particular for an osteo-synthetic fixation device in a structure in which the construction components are off-set from the force axis of the loading force that retains them.

Abstract: The connection device (20) for adjustable connection of a first with a second structural element (12, 13), particularly tubes or rods, for a setting device has an external component (21) with a cylindrical hole and two internal components (22) inserted into the hole so that they can be slid axially and rotatably, each of which said internal components (22) has through openings (24, 25) crossways to the axial direction of the components to hold a structural element (12, 13). By means of loading means (23, 29), designed as a nut/screw connection, the internal component (2) is pushed axially to the external component (21) and thereby grips the inserted structural elements (12, 13).

Abstract: A pedicle hook for use in treatment of the spine has a bifurcated blade in which one of the legs formed by the bifurcation is longer than the other.

Abstract: A pedicle screw or hook has a slotted head for receiving a support rod. A support element in the head transverse to the slot provides limited pivotal movement for the support rod.
