摘要： A fusionless method of treating spinal deformities in the spine of a child or young adult involves attaching a tether to vertebral bodies on the convex side of the spine. Deformities are treated by using the tether to selectively constrain growth in a portion of the convex side of the spine. One device for tethering the spine is a combination of a strand threaded through channels defined in a set of blocks attached to the vertebral bodies on the convex side of the spine. Another device useful in the method is to attach spinal staples, preferably made of a shape memory alloy, to vertebral bodies, the staples spanning the intervertebral disc space.

摘要： A device for supporting weak bony structures comprises an elongated tubular body having first and second ends configured for contacting adjacent bony structures. A tubular body is formed by a plurality of intersecting elongate bars with a first group of bars having their longitudinal axes arranged perpendicular to the axis of the tubular body, and a second group of bars having their axes arranged at non-perpendicular angles relative to the body axis. The tubular body also includes a plurality of joints formed by the intersection of two perpendicular bars and four angled bars. The ends of the tubular body are defined only by the intersection of angled bars. The ends include a plurality of substantially flat end surfaces that have a surface area greater than the combined cross-sectional areas of the intersecting angled bars forming the joints at the end of the body. In a preferred embodiment, the end surfaces have an undercut between the surfaces and the intersecting angled bars. The tubular body can assume various shapes when viewed from an end, such as circular and non-circular shapes including at least one flat side.

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： A multi-axial bone screw assembly includes a bone screw having a partially spherical head. The bone screw head is truncated at an upper surface in which a tool receiving recess is defined. The assembly includes a receiver member including a central bore that defines a tapered recess to receive a contracting collet carrying the head of the bone screw. The bore of the receiver member also defines a channel communicating with the recess and configured to receive a spinal rod therein. A portion of the channel is threaded to receive a set screw above the rod. The assembly also includes a contracting collet disposed between the rod and the head of the bone screw. The collet defines a partially spherical recess to receive the head of the bone screw, and includes deflectable fingers that substantially surround the screw head. As the set screw is tightened into the receiver member, the set screw compresses the rod against the collet, which presses the collet into the tapered recess of the receiver member, thereby deflecting the fingers of the collet against the bone screw head.

摘要： This invention relates to orthopedic implants 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： Devices, methods and systems for stabilizing at least a portion of the spinal column are provided. Devices include anchors and coupling members for engaging an elongate member. Systems include an elongate member sized to span a distance between at least two vertebral bodies and being at least partially formed of a flexible material. A number of anchors and coupling members are used to secure the elongate member to each of the vertebral bodies. The anchors can be compressed towards one another and the elongate member secured thereto and/or the elongate member can be tensioned to provide corrective forces to the spine.

摘要： The treatment and correction of spinal deformities, such as scoliosis, is accomplished without the need for fusion of the intervertebral disc space. A surgical technique is provided in which opening and closing osteotomies are created in the affected vertebrae. Correction devices are provided which hold the osteotomies in either their closed or open orientations. The correction devices include bone-piercing anchors, some in the form of staples, holding the vertebral body on opposite sides of the body to retain the osteotomies in their desired orientation. In the opening osteotomies, the correction devices include a wedge member that is disposed within the opened wedge osteotomy and in contact with the vertebral body. The correction devices also include connection members which can be used to engage the devices to an elongated member spanning the spine, such as a spinal rod or a metal or non-metal cable or tether. Once bone union has occurred in the instrumented vertebrae, the spinal rod or cable or tether can be disconnected from the correction devices and removed from the patient. In another aspect of the invention, curvature deformities in two planes can be corrected using the same techniques and devices.
