A spinal construct comprises at least one member that defines a first implant cavity and a second implant cavity oriented transverse to the first implant cavity. The at least one member has a surface that includes a lock disposed with the first implant cavity. Systems, implants, surgical instruments and methods of use are disclosed.

A technique is presented for computer-assisted planning of fastener placement in vertebrae that are to be stabilized by a pre-formed spinal rod, wherein two or more fasteners are to couple the rod to the vertebrae. At least one of a target shape of the spine and a shape of the pre-formed rod is defined in patient-specific shape data, a bone density of at least one of the vertebrae is defined in patient-specific bone density data, and patient-specific anatomical data are provided. A force distribution along a length of the rod may be calculated based on the shape data and the anatomical data. A planning result for fastener placement may be generated based on the bone density data of a given vertebra and the calculated force distribution.

A fracture treatment system can include a pair of implants cross-pinned into the medullary canal of a bone, guided by at least one guide wire with at least two diameters. The system allows for more accurate sizing of the length of implants needed to achieve bicortical purchase for enhanced stability, as well as anti-rotation of the fracture site. The more accurate sizing and placement of the cross-pinned implants additionally allow both ends of the implants to recess beneath or be flush with the outer surface of the bone, which can reduce the risk of infection. The guide wire can allow the implants to be inserted using a cannulated technique for easier surgical procedure and better outcome, with the implants having sufficient wall thickness for the desired length to achieve bicortical purchase while keeping the shaft outer diameter of the implant to be similar to a diameter of the guide wire.

Disclosed are devices, systems and methods for modifying, cutting and/or shaping surgical fixation components of various configurations, including spinal fixation rods and related components.

A two-piece suspension pedicle anchor and its system and component-set is disclosed. The two-piece suspension pedicle anchor comprises a proximal piece and a distal piece that can rotate relatively. An external thread is arranged on the outer surface of the proximal piece, and a transverse through hole for an artificial ligament to pass through is arranged at the distal piece. As the two-piece suspension pedicle anchor is rotated and gradually locked into the bone, only the proximal piece is rotated, and the distal piece with the artificial ligament is pushed down but not rotated; in addition, the artificial ligament will be brought into the bone along with the distal piece and sandwiched between the outer surface of the proximal piece and the bone, that is, the artificial ligament will be sandwiched and fixed between the anchor-bone interface without wrapping around the outer surface of the proximal piece.

Anatomic points within the body are projected outside the body through the use of extenders. The projected points may then be used for measurement, or to facilitate the selection or configuration of an implant that is to be positioned proximate the anatomic points. Such an implant may be a rod for a posterior spinal fusion system. Pedicle screws may be implanted into pedicles of the spine, and may then serve as anchors for the extenders. The extenders may have rod interfaces that receive the rod in a manner that mimics the geometry of the pedicle screws so that the selected or configured contoured rod will properly fit into engagement with the pedicle screws.

A system and a method are provided for a surgical bending instrument for bending surgical implants. The surgical bending instrument comprises a body including a center lever comprising a wheel and a cam. A distal force applicator comprises a driver centered between a first grip and a second grip. In some embodiments, the distal force applicator is configured to retain a surgical staple, such that the surgical staple may be changed to a distracted configuration suitable for implantation at a bone fixation or fusion site of a patient. In some embodiments, the distal force applicator is configured to bend a bone fusion plate so as to tailor the plate to specific anatomy of the patient's bone.

The various embodiments disclosed herein relate to bone fixation or fusion devices, including intramedullary fixation or fusion devices that are implanted around the target bone. Certain device embodiments relates to devices that can be bent or otherwise deformed to replicate the natural or desired curve of the bone or joint being treated. In addition, other embodiments relate to implantation devices that can be used to implant or position the bone fixation or fusion devices.

Systems and methods are disclosed in which changes in the position and/or orientation of an anatomical structure or of a surgical tool can be measured quantitatively during surgery. In some embodiments, the systems and methods disclosed herein can make use of inertial motion sensors to determine a position or orientation of an instrument or anatomy at different times and to calculate changes between different positions or orientations. In other embodiments, such sensors can be utilized in conjunction with imaging devices to correlate sensor position with anatomical landmarks, thereby permitting determination of absolute angular orientation of a landmark. Such systems and methods can facilitate real-time tracking of progress during a variety of procedures, including, e.g., spinal deformity correction, etc.

A bone material dispensing apparatus for preparing, mixing, and dispensing bone material into a foldable container is provided. In some embodiments, the dispensing apparatus comprises a tray and a foldable container. The tray includes a mixing surface, a dispensing surface and a means to measure the amount of material to be dispensed. A kit including a tray, a foldable container, and a spatula are also provided. A method of using the dispensing apparatus to deliver the bone material to a bone detect is also provided.
