A system for performing surgical repair of the spine includes a distractor and a permanently implanted bone plate system. A surgical repair methodology is also disclosed that employs an implanted bone plate system with a substantially void internal volume which is attached to adjacent vertebrae subsequent to the distraction and adjustment of curvature of the vertebrae and prior to the excision of disc and/or end plate tissue through the bone plate. The device further facilitates the subsequent delivery of an interbody repair device for the purpose of either fusion or dynamic stabilization, such as by disc arthroplasty. The plate may be permanently implanted, such as when a fusion between the attached vertebral bodies is desired, but it need not be permanently implanted.

The present invention relates to an internal fixator device (1) of the bone plate type to be used as synthesis means in anatomical regions or epiphyses/metaphyses with poor coating of soft tissue, of the type comprising a two-lobe or eight-shaped bone plate (2) comprising a pair of lobed portions (23, 24) which are linked by a central linking portion (15) and in each of which at least one through-hole (3, 4) is formed to receive a corresponding bone fixation screw (5). Advantageously, each of the pair of lobed portions (23, 24) of the bone plate (2) has an upper surface (7) inclined relative to a reference plane (X) coinciding with a second upper surface of the linking central portion (15) of the bone plate (2), and a lower surface (6) configured for contact with the bone and inclined relative to the same reference plane (X) with a smaller inclination.

Surgical plating systems, devices, and related methods for stabilizing and immobilizing portions of a body for surgical procedures, e.g., spinal surgery, are disclosed herein. The plating systems can have narrow profiles that minimize trauma to the patient. An exemplary bone plating system can include a bone plate having one or more holes for receiving attachment members to couple the bone plate to a bony structure. The plating system can provide multipoint fixation to anatomical structures of the patient to prevent unwanted migration of the bone plate and/or unintentional back-out of the attachment members. In some embodiments, the attachment members can be disposed at various trajectories and angles relative to plating structures and can include a mesh construct and/or additional locking features. In some embodiments, the plating system can be introduced into the patient via an access tube to further limit the invasiveness of the procedure.

Systems for the minimally invasive repair, stabilization and/or fixation of a fractured bone, such as a rib, are disclosed. The systems include one or more rods/support members that are designed to extend along a dimension of a bone being repaired and secure the fractured bone. The support members can be photodynamic and are formed using an expandable member that is filled with a light-sensitive liquid that is cured to form the rigid support member. Two or more clamps are used to secure the support member(s) to the rib or other bone. Minimally invasive surgical methods for securing the systems to a fractured bone are also disclosed.

A load sharing bone plate has a plurality of directional apertures configured to effectively support and share the load with a fractured bone to promote healing. A load sharing bone plate may have a body portion that is thinner and be configured to be secured with smaller fasteners than conventional bone plates. A load sharing bone plate has a plurality of directional apertures, configured to direct a fastener is a specific orientation, such as in an oblique angle to the length and/or in an oblique angle to the width of the bone plate. A load sharing bone plate may be configured with a load sharing extension on at least one end that is configured to reduce stress concentration at the end of the bone plate. A load sharing extension may have a tapered thickness and/or width from the body portion to the extended end.

According to an aspect, a spacing element for spacing a fixation plate away from a bone to which the fixation plate is secured is provided. The spacing element has a body with a bone interface side and a plate interface side and sidewalls extending thereinbetween, said bone interface side having a bone contacting surface having contours conforming to surface contours of the bone. A corresponding fixation plate, fixation plate kit, and method for designing a patient-specific spacing element are also provided.

According to an aspect, a preoperative planning method for a high-tibial knee osteotomy procedure is provided. The method includes: a) constructing a 3D model of a patient's bones; b) analyzing the 3D model to select a desired correction angle to apply to the patient's tibia bone to adjust a mechanical axis thereof; c) determining surgical steps required to apply the desired correction angle to the patient's tibia bone; d) designing a patient-specific guide to guide generic surgical tools in performing the surgical steps, the patient-specific guide being designed to conform to the anatomy of the patient's bones based on the 3D model; and e) manufacturing the patient-specific guide designed in step d). A corresponding kit, system and computer readable medium for performing the method are also provided.

A bone plate can be used to fixate one or more bones. In some examples, the bone plate defines an elongated body having a plurality of fixation holes arrayed at different points along the length of the body. For example, the bone plate may have opposed fixation holes separated by a bridge. The bone plate may be bent or shaped along a central longitudinal axis extending through the elongated body and also twisted around the central longitudinal axis. The bending and twisting can position each fixation hole of the elongated body in a different plane in three-dimensional space.
