摘要： A fusion implant apparatus for facilitating fusion of adjacent bone structures includes a threadless implant member which is positioned between adjacent opposed bone structures. The implant member defines a longitudinal axis and first and second longitudinal ends and has an outer wall which is dimensioned to engage the opposed bone structures upon positioning therebetween in supporting relation therewith. The outer wall defines an internal cavity for the reception of bone growth inducing substances and includes a plurality of apertures which extend therethrough in communication with the internal cavity to permit fusion of vertebral bone tissue. The implant member also includes an intermediate portion which defines a cross-sectional dimension transverse to the longitudinal axis which is greater than the respective cross-sectional dimensions of the first and second longitudinal ends of the implant member.

摘要： An apparatus for facilitating fusion of adjacent bony structures includes an implant body dimensioned for positioning between adjacent bone structures to maintain the bone structures in desired spaced relation during interbody fusion. The implant body defines a longitudinal axis and has an outer wall extending along the longitudinal axis. The outer wall includes a plurality of annular serrated portions spaced along the longitudinal axis. The annular serrated portions are dimensioned and configured to engage the adjacent bone structures to facilitate retention of the implant member therewithin. The implant member further include at least one concave surface at least partially extending along the longitudinal axis, whereby the transverse cross-sectional dimension along a first transverse axis inclusive of the concave surface is less than the transverse cross-sectional dimension along a second transverse axis. The concave surface extends substantially along the length of the implant member. Preferably, the implant body includes a pair of diametrically opposed concave wall surfaces.

摘要： A simple and flexible artificial ligament which easily conforms to a patient's anatomy and can be used independently or in combination with an intervertebral graft, implant or prosthesis to return stability to the spine subsequent to a surgical spinal procedure is disclosed. In one preferred embodiment, the artificial ligament (100) is in the form of a flexible conformable plate (102) dimensioned to span adjacent vertebrae and having openings (108) for reception of bone screws, fasteners (110), etc. to mount the plate to the vertebrae. The biomechanical supporting characteristics of the plate approximate the characteristics of the ligament (e.g., anterior spinal) which it replaces thereby providing appropriate support to the spine in extension which also permitting normal spine mobility. A method of supporting adjacent vertebrae with the artificial ligament is also disclosed.

摘要： A bone fixation apparatus (10) is disclosed which includes an elongated plate member (12) with at least two pairs of circular openings (24, 26) and a series of circular openings (62) positioned along the plate member (12). The circular openings each form a cavity (30) with walls (31) extending between the upper and lower plate member surfaces (16, 18), the cavities having smaller diameter portions (32) at the plate member surfaces (16, 18) and a larger diameter portion (34) therebetween. The cavities are configured in the shape of two inverted cones (31a, 31b) with matching base circles (31c) for allowing angulation of an implanted bone screw (14). A plurality of bone screws (14) are provided, each having a threaded first end portion (36) and an ellipsoid-shaped enlarged second end portion (40). A locking member (48) is also provided which connects to the second end portion (40) of each bone screw (14) for expanding the second end portion (40) so as to grip the cavity wall (31) of the plate member (12).

摘要： An intervertebral prosthesis includes a disc member dimensioned for insertion within an intervertebral space between adjacent vertebrae to replace at least a portion of an intervertebral disc removed therefrom. The disc member has sufficient rigidity to support the adjacent vertebrae in spaced relation, and defines a longitudinal axis extending the height of the disc member and a lateral axis transverse to the longitudinal axis. The disc member includes an exterior wall which has a slit defined therein. The slit defines a longitudinal component of direction and a lateral component of direction. Preferably, the exterior wall includes a plurality of helical slits, adjacent slits being disposed in at least partial overlapping relation to define an overlapping region. Upon insertion of the disc member within the intervertebral space with the support surfaces in contacting engagement with respective vertebral portions of the adjacent vertebrae, forces exerted by the vertebral portions on the support surfaces are transferred along the exterior wall through the overlapping region.
