摘要： The present invention relates to a bone fixation assembly for securing a fixation device (10), such as a bone plate, to bone. The assembly includes the fixation device (10), a bushing (14), a fastening screw (32), and a locking screw (34). The bushing (14) is seated within a through hole (12) in the fixation device (10) and can rotate within the through hole (12) and has a sidewall (20) with a bore (24). The sidewall (20) has at least one slot (28; 28a) for allowing outward expansion of the sidewall (20) against the through hole (12) to thereby lock the bushing (14) at a selected angle relative to the axis of the through hole (12). The fastening screw (32) has a threaded shaft (36) for insertion through the bore (24) of the bushing (14) and threads into bone to secure the bushing (14) and fixation device (10) to bone. The head (38) of the fastening screw (32) fits in the bushing (14) and includes a radial wall (44) and open end defining a recess (50). The radial side wall (44) has at least one slit (46) for allowing outward expansion of the radial wall (44) thereby outwardly expanding the sidewall (20) of the bushing (14). The locking screw (34) has a body that threads in the head (38) of the fastening screw (32) to thereby outwardly expand the radial wall (44) of the fastening screw (32).

摘要： A cranial spring clip (10) for attaching a bone flap (16) to a skull (22) is disclosed. The clip (10) includes a substantially flat flap clipping portion (12), a substantially flat skull clipping portion (18), an extension (24) disposed between, connecting, and substantially perpendicular to the flap clipping portion (12) and the skull clipping portion (18), at least one burr (32) attached to the extension (24). When the clip (10) is implanted, the topography of the flap clipping portion (12) and skull clipping portion (18), the only parts of the clip (10) above the outer table of the skull (22), provides the clip (10) with a low profile. At least a portion of the extension (24) is resilient in nature so that the resilient portion flexes inward upon insertion in the saw gap and then flexes back to fix the clip (10) in place. The burr (32) penetrates the skull (22) to also fix the clip (10) in place. As the extension (24) has a length that is shorter than the thickness of the skull (22) and the bone flap (16), there is minimal possibility of accidental injury to the brain. A fastening element can be located on the extension (24) so that it is substantially perpendicular to the extension (24) when implanted. Alternatively, a fastening element can be located on the flap clipping portion (12) so that it is substantially perpendicular to the flap clipping portion (12). The extension (24) can be either substantially flat or U-shaped.

摘要： The method for the determination of reduction parameters comprises: A) measuring points on the surfaces of the corresponding bones of interest at the patient's left and right side of the body; B) establishing a plane of symmetry containing an anterior-posterior axis and a proximal-distal axis; C) a mirror image of the patient's non-fractured bone is generated symmetrically to the plane of symmetry; and D) the reduction parameters are then determined by comparison of the coordinates of the points at the fractured bone with the coordinates of the points within the mirror image. The device according to the invention comprises: A) a cylindric or prismatic reference bar; B) clamps displaceable on and fastenable to the reference bar; C) screws or pins screwable into the bone transversely to the reference bar within the clamps; and D) an adjustable clamp to fasten a pin capable of being set with its tip to desired points on the surface of the bone.

摘要： A variable angle spinal fixation system is disclosed. The system includes a longitudinal member positionable along a spinal column, a fastener (14) having a threaded end for engaging a vertebra, and a connector member (12) for connecting the fastener (14) and the longitudinal member. The connector member (12) has a channel (26) extending through side surfaces of the connector member (12) for receiving the longitudinal member, an opening (32) laterally displaced from the channel (26) and extending through top and bottom surfaces of the connector member (12) for receiving the fastener (14), and a fastener clamping element for securing the fastener (14) in the opening (32) at a surgeon selected angle relative to the connector member (12) and longitudinal member. The system according to the present invention allows angulation of the fastener (14) to accommodate complex pathologies.

摘要： The invention relates to a device for use in osteosynthesis, in particular for drilling, cutting threads or inserting implants. Said device comprises a drill bushing (1) with a longitudinal axis (2), a rear end (6), into which an instrument or implant can be introduced, a front end (5) that can be placed on an implant or a bone and a hollow chamber (11) lying coaxially to the longitudinal axis, a supporting handle (9) that can be connected to the drill bushing (1) and a coolant connection (10), through which a coolant can be conducted directly into the hollow chamber (11) of the drill bushing (1). Said drill bushing (1) is divided into two parts along the longitudinal axis (2). The drill bushing (1) can thus be used to tighten screws with a larger diameter screw head. Once the screw has been tightened, the half-shells (3; 4) of the drill bushing (1) are pushed apart and the drill bushing (1) is removed from the screw, without being hindered by the larger diameter screw head.
