摘要： Bone screws and bone plates are provided that offer the surgeon the ability to either assemble the screws to the plate, or the plate to the screws, depending on the surgeon's preference and the patient's circumstances. The bone screws and bone plates of the present invention include a combination of geometric configurations that allow the screws and plates to fit together from different assembly directions. Additionally, the bone screws and bone plates can include material resilience features to allow expansion/contraction during assembly to allow bidirectional attachment to one another.

摘要： A dilator retractor and the dilators that are used for minimally invasive spinal surgery or other surgery are configured to accommodate the anatomical structure of the patient as by configuring the cross sectional area in an elliptical shape, or by forming a funnel configuration with the wider end at the proximate end. In some embodiments the distal end is contoured to also accommodate the anatomical structure of the patient so that a cylindrically shaped, funnel shaped, ovoid shaped dilator retractor can be sloped or tunneled to accommodate the bone structure of the patient or provide access for implants. The dilator retractor is made with different lengths to accommodate the depth of the cavity formed by the dilators.

摘要： Methods and devices are provided for retracting tissue. In one exemplary embodiment, a retractor is provided that includes a base, a plurality of blades extending from the base, and an actuator coupled to the base and operatively connected to the blades. The actuator can be configured to be actuated to move the blades relative to the base, thereby allowing the blades to retract tissue. The actuator can be self-locking so as to allow the blades to be freely movable within their entire range of motion relative to the base through actuation of the actuator without using another mechanism to lock the blades in a fixed position and to unlock the blades from the fixed position. The retractor can be formed from one or more radiolucent materials.

摘要： A bone plate system including a bone plate and a bone screw with an integrated locking mechanism is disclosed. The bone screw includes an elongate member having a threaded shank and a bone screw head that is radially deformable. The integrated locking mechanism sits within the bone screw head and can rotate between a locked condition and an unlocked condition. When the bone screw head is seated within an aperture in the bone plate, rotating the integrated locking mechanism into the locked condition helps to prevent bone screw backout.

摘要： Multiple, small, staple-like supports are inserted through a small tube into the disc space then rotated into position on the edge of the vertebral bodies. The tooth-like geometry of the proximal and distal faces of these staples mates with the outer edge of the vertebral body, extending past the front of the endplate anteriorly. The staples have teeth that dig into the endplate on the inside of the rim as well.

摘要： A guide device is provided for use with a spinal fixation element that has at least one pair of thru bores formed therein. The guide device generally includes an elongate shaft having a proximal end and a distal end. A guide member is coupled to the distal end of the elongate shaft and it includes at least one pathway extending therethrough, and at least one alignment element that is positioned distal of the guide member. Each alignment element(s) is adapted to interact with a spinal fixation element to position the guide member with respect to the spinal fixation element such that the each pathway in the guide member is aligned with a corresponding thru bore formed in the spinal fixation element. The guide member can then be used to guide tools, devices, and/or implants through each pathway in the spinal fixation element and into bone.

摘要： Devices and methods are provided for treatment of the cervical spine. The devices and methods allow for treatment to be delivered from a lateral or posterior-lateral location of a subject, proximate to the cervical region of the spine. One exemplary embodiment of a spinal implant includes an elongate cage member and a plate member appended to a proximal end of the cage member. The plate member can be oriented in a manner such that it is asymmetric with respect to a long axis of the cage member. In another exemplary embodiment, an implant includes a cage member having a distal end that has an asymmetrical, bulleted shape such that the distal end is biased towards a superior or cranial direction. In a third exemplary embodiment, an implant includes a spinal fixation element and at least two mounting eyelets formed thereon. Exemplary methods related to implanting spinal implants from a lateral or posterior-lateral location are also provided.

摘要： Various bone screws and methods for accommodating stiffness regions in bone are provided. The bone screw provided generally includes a receiver member configured to receive a fixation element and an elongate shank having different stiffness regions. In one embodiment, the elongate shank can include at least one slot for increasing the flexibility of the slotted portion of the elongate shank. In another embodiment, the elongate shank can be manufactured from materials selected to alter the stiffness of the shank. The different stiffness regions allow the bone screw to mimic the flexibility of bone, reducing the risk of fracture of the bone and/or loosening of the bone screw.
