摘要： Screw and rod systems include polyaxial and hinge joints which provide independent first and second ranges of motion. The first and second ranges of motion are additive in a direction along the rod, so that the screw has greater angulation relative to the rod along the rod than transverse to the rod.

摘要： Interbody spacers are expandable horizontally and vertically by an application of axial force, and lockable in an expanded configuration. The spacers include support members interconnected to end bodies by pivotable link members. The spacers are introduced between vertebral bodies in a compressed configuration and expanded to fill the intervertebral space and provide support and selective lordotic correction. Graft material may be introduced into the expanded spacer. Provisional and/or supplementary locking means lock the spacers in the expanded configuration. Embodiments of the spacers include symmetrically and asymmetrically configured spacers. Methods of expansion include symmetric expansion or asymmetric expansion along each of two directions.

摘要： Systems and methods for joint preparation and fusion are disclosed. The system includes a cutting device having a handle, and rigid blade member. The blade member may include cutting edges on first and second sides, and may be curved in one or more planes. The blade member may be deployed to project outside of an outer tube, and the cutting device may be rotated to create a circular cavity. In a method of use, a cannula provides access to a procedure site such as a joint. A pathway to the joint is created, and the cutting device is inserted and deployed to undercut a cavity in the joint. A fusion device may be implanted across the joint to provide compression and fuse the joint. The system may also include instrumentation for creating access to a joint, bone graft insertion and implant insertion.

摘要： An implant for fusing a joint between first and second bone portions. The implant includes a screw member, and a washer polyaxially rotatable relative to the screw member. The screw member includes a head, a lag zone, and a threaded engagement zone. The implant includes a fusion zone for joint compression, extending from the washer to the proximal end of the engagement zone. Fenestrations may be present in the fusion zone. The length of the fusion zone ranges from about 10 mm to about 37 mm. Different surface finishes including roughened and non-roughened may be applied selectively to selected portions of the implant. In an embodiment, the joint is a sacro-iliac joint, and upon implantation the implant extends from the exterior of the ilium, across the joint and into the sacral vertebral body. Instrumentation and methods for preparing the joint and implanting the implant are disclosed.

摘要： A system for single tunnel, double bundle anterior cruciate ligament reconstruction includes implant constructs and instruments. The implant constructs provide a combination of cortical fixation and bone tunnel aperture fixation. The implant constructs separate a graft into distinct bundles. The instruments are used to prepare shaped bone tunnels to receive the implant constructs and graft bundles. Methods for reconstructing the antero-medial and postero-lateral bundles of the anterior cruciate ligament may rely on single femoral and tibial tunnels and a single strand of graft.

摘要： Fasteners and instruments with fastener retention mechanisms are disclosed. The fastener retention mechanisms may be independent of fastener deployment forces, such as torque. The fastener retention mechanisms may include spring elements of the instruments, whose flexion is limited by other features of the instruments so that the springs function only in their elastic zones and are prevented from experiencing yielding, plastic deformation, bending, cracking, or breaking.
