摘要： Anatomic points within the body are projected outside the body through the use of extenders (180, 182, 188). The projected points may then be used for measurement, or to facilitate the selection or configuration of an implant that is positioned proximate the anatomic points using a slotted cannula (143). Such an implant may be a rod (270) for a posterior spinal fusion system. Pedicle screws (140, 142, 148) may be implanted into pedicles of the spine, and may then serve as anchors for the extenders. The extenders (180, 182, 188) may have rod interfaces (214, 216, 218) that receive the rod (270) in a manner that mimics the geometry of the pedicle screws (140, 142, 148) so that the selected or configured contoured rod (270) will properly fit into engagement with the pedicle screws (140, 142, 148).

摘要： A system and method for treating a defect. The system may comprise a first expandable barrier insertable into a defect interior space in a compact state and then expanded once positioned inside the defect. The first expandable barrier is expanded to be positioned against the inner surface of the defect. The system may also comprise a second barrier which may be expandable, positioned against the outer surface of the defect. Each of the first and second barriers may expand laterally to a greater extent than axially. The first and second barriers may be in communication through a connection member which couples the two barriers together. The barriers each obliterate the defect and can prevent subsequent CSF or other fluid leaks. Fibrin glue may be introduced into the defect to seal and secure the barriers to the defect. Each barrier may comprise a mesh, a basket, an umbrella or a balloon.

摘要： A knee prosthesis including femoral and tibial implants, a tibial insert and a cam post assembly. The femoral implant is secured to a femur and has a cam feature and condyles. The tibial implant is secured to a tibia. The tibial insert has articulating surfaces that match the contours of the condyles of the femoral implant, and may have a medial boss that aligns with the tibial implant to provide rotation about a medially displaced rotation axis. A cam post is secured to the tibial implant and passes through a channel of the tibial insert. A motion limiting structure provides limits to motion between the tibial insert and the tibial baseplate. The cam post assembly interacts with the femoral implant cam feature and allows more anatomically correct rollback and femoral external rotation during knee flexion, and varus/valgus support to the femur.

摘要： An implantable fixation system for fusing a joint between a first bone and a second bone. The system may include an anchor, standoff, bolt, and cortical washer. The system may be implanted across the joint along a single trajectory, the length of the system adjustable to provide compressive force between the anchor and the cortical washer. The system may be implanted across a tibiotalar joint with the anchor positioned in the sinus tarsi. A spacing member may be inserted between the two bones and the fixation system implanted to extend through an opening in the spacing member. The spacing member may be anatomically shaped and/or provide deformity correction. An ankle arthroplasty system may include a tibial plate, a talar plate, and a bearing insert. The plates may be anchored to the tibia and talus along a single trajectory. The ankle arthroplasty system may be revisable to a fusion system.

摘要： A compression and distraction shaft assembly applies compression and distraction to bones including vertebrae. Shaft A assembly and shaft B assembly are attached together via a polyaxial fulcrum. The polyaxial fulcrum allows all rotational degrees of freedom between shaft A assembly and shaft B assembly. Such fulcrum, during compression and distraction, does not impart ancillary stresses or motion to vertebrae. An hourglass-shaped bore for engaging pliers is formed in approximately middle of both the shaft A assembly and the shaft B assembly. Distraction pliers having cylindrical tips are used to apply distraction to vertebrae. Once handles are pressed to impart an appropriate amount of distraction to the vertebrae, they are locked in this position. Compression pliers having cylindrical tips are used to apply compression to vertebrae. Once handles are pressed to impart an appropriate amount of compression to the vertebrae, they are locked in this position.

摘要： Disclosed herein are systems and methods for filling bone voids which may be present at the time of surgery. The systems disclosed herein generally include a baseplate component, a spacer component, and void filler component. The spacer component is generally assembled to the baseplate component with a taper or press-fit, for example, in one of a plurality of selected axial positions. The void filler component is then generally assembled to the spacer component in one of a plurality of selected axial positions. The void filler component preferably has an outer surface with portions having varying diameters such that the outer surface thereof can be received within a canal of a bone and contact the bone forming the canal at different locations in order to aid in stabilizing the assembled components in the canal.

摘要： An implantable bone anchor assembly for fixing an elongated member such as a spinal rod may include a bone anchor, a coupling head configured to receive the bone anchor and the elongated member, and a locking mechanism. The locking mechanism may provide compressive force to simultaneously fix the position of the elongated member and lock out polyaxial rotation of the bone anchor relative to the coupling head. The locking mechanism may include an engagement member with an oblique surface configured to slide along an oblique surface of the coupling head into engagement with the elongated member. The bone anchor may comprise a head portion and a threaded portion which may be coupled with the coupling head and joined together during manufacture. The assembly may further include a pin and/or a collar to retain the bone anchor. The bone anchor may be side-loaded into the coupling head.
