摘要： This invention relates to orthopedic implants (10, 50, 100, 140, 190, 250, 280, 300, 320, 340, 360, 370, 380, 400 and 440) and to methods of treating bone defects. More specifically, but not exclusively, the present invention is directed to non-metallic implants and to methods for intra-operative assembly and fixation of orthopedic implants to facilitate medical treatment. The non-metallic implant assembly can be secured to underlying tissue by a fastener, such as a bone screw, that is capable of swelling on contact with fluid in the underlying tissue. Alternatively, the non-metallic implant assembly can be assembled intra-operatively using a fastener that is adhesively bonded to a bone plate or the bone plate can be deformed using heat, force or solvents to inhibit withdrawal of the fastener. In preferred embodiments, both the fastener and the bone plate are formed of biodegradable material.

摘要： In one embodiment, a spinal fixation assembly includes an elongated member, such as a spinal rod, configured for placement adjacent the spine and a bone engaging fastener, such as a bone screw having a lower portion configured for engaging a vertebra and a head that is at least partially spherical. The assembly further includes a receiver member defining a bore therethrough from a top end to a bottom end, a recess for receiving the head of the bone screwing fastener therein, and a lower opening at said bottom end of the receiver member through which the bone screw extends. The recess is configured to at permit pivoting of the bone screw within the receiver member until the head is fixed within the recess. The receiver member also includes a channel communicating with the bore and having an upper opening at the top end of the receiver member for insertion of the spinal rod into the channel. In one embodiment, two compression members are provided, each being formed of a temperature responsive material and having a first configuration at a first temperature and a different second configuration at a different second temperature in which the compression member contracts about a portion of the receiver member to thereby compress the receiver member about both the head of the bone screw within the recess and the spinal rod within the channel.

摘要： Apparatus for the fixation of bone fractures, limb lengthening, and the correction of deformities comprises an improved composite plastic carbon fibre ring that is formed in a mould, or machined with a stepped end portion that allows half rings to be assembled in a common plane. In the manufacture of the apparatus a mould may be used wherein multiple rings can be formed by stacking the rings with, eg. a polytetrafluoroethylene layer therebetween and Wherein circumferential braid reinforcement of carbon fibre adds strength at the circumferential inner and outer curved surfaces of the rings and half rings.

摘要： Apparatus for the fixation of bone fractures and the correction of congenital deformities uses an improved adjustment device that allows selective rotation or lateral translation of one external fixation ring with respect to other external fixation rings. The adjustment devices attaches to a pair of first and second tie rod sections and shifts the first tie rod section with respect to the second tie rod section during adjustment. The adjustment device has a lateral slot that defines the path of movement for one of the translation rod sections. A travelling block connected to the moving tie section tracks the slot during use.

摘要： A method of augmenting an intervertebral disc by injecting particles of collagen-based material into the disc. The particles may be dehydrated before implantation, and rehydrated after implantation, or they may be implanted in a "wet" state - such as a slurry or gel. Radiocontrast materials may be included to enhance imaging of the injected material. Other additives may include analgesics, antibiotics, proteoglycans, growth factors, and/or other cells effective to promote healing and/or proper disc function.

摘要： An improved apparatus is provided to allow for an adjustable length tether (10) for use in the spine and other parts of the body. The tether (10) comprises an artificial strand (11) with an eyelet (23) formed in one end (13), the other end (15) being looped through the eyelet (23). The other end (15) is then secured with respect to the eyelet (23) by a crimp (50), the excess length being cut off after the length of the tether (10) has been given an appropriate tension. Alternatively, the eyelet end (13) may be formed around a grommet (123). The crimp (50) may be separate from the grommet (123) or a part of the grommet (123). The mechanism by which the length is adjusted in some cases will take advantage of the shape memory properties of alloys such as nickel-titanium.
