  • Patent number: 10729417
    Abstract: A method for imparting tension across a human knee joint which includes a femur bone, a tibia bone, a patella bone, a patellar tendon, and ligaments, wherein the ligaments and patellar tendon are under anatomical tension to connect the femur and tibia together, creating a load-bearing articulating joint. The method includes: providing a tensioning device, including: a baseplate; a top plate; and a linkage interconnecting the baseplate and the top plate and operable to move the tensioning device between retracted and extended positions, wherein the top plate is pivotally connected to the linkage so as to be able to freely pivot about a pivot axis; positioning the tensioning device between the femur and the tibia; applying an actuating force to the linkage to move the tensioning device towards the extended position, so as to impart a controlled separating force driving the femur and tibia apart to extend the ligaments.

  • Patent number: 10675059
    Abstract: The present disclosure provides dynamic cranial fixation devices and related methods for attaching a resected bone portion(s), or a bone flap, to the skull in such a manner that allows for brain swelling to occur with minimal constraint following a craniotomy or craniectomy. The present disclosure provides dynamic cranial fixation devices and related methods that provide outward movement of the bone flap as the brain swells underneath the bone flap to prevent or reduce a rise in the intracranial pressure. Once the brain swelling resolves, the dynamic cranial fixation devices and related methods of the present disclosure allow the bone flap to return to its original position (before resection) without further surgery, implantation or the like. Once the bone flap return to its original position (or substantially similar position), the bone flap may fuse with the neighboring bone(s), potentially with the assistance of one or more fusion aid.

    Abstract: The present disclosure provides a provisional tibial prosthesis system for a set of prosthetic knee joints for implantation in a natural knee, the provisional tibial prosthesis system including a bearing component and a bearing support, the spacing of the bearing component from the bearing support is adjustable to allow for representation of a variety of different sized final tibial prostheses. In this system, only one provisional bearing component corresponding to each level of constraint is needed and shims are used to adjust the spacing of the bearing component from the beating support. The shims are slidably insertable between the bearing component and the bearing support in an anterior/posterior direction to allow for adjustment of the spacing of the bearing component from the bearing support. The number of provisional components needed during knee surgery is reduced and adjustment of the system only requires the knee joint to be distracted by a distance equal to the height of a particular shim.

    Abstract: Embodiments of the invention include a system and method for coupling a graft to a bone. A graft preparation tool may be used to place one or more holes in a graft and an offset measurement tool may be used to determine the distance of the one or more holes from an edge of the graft to be aligned with a portion of the bone. One or more complementary holes may then be created in the bone and fasteners applied through the holes to couple the graft to the bone.

  • Patent number: 10130375
    Abstract: Methods and instruments for performing a kinematically-aligned total knee arthroplasty (TKA) are disclosed. Goals of the kinematically-aligned TKA can include restoration of (1) the femoral and tibial joint lines to the patient's natural joint line, (2) the patient's Hip-Knee-Ankle alignment to their constitutional alignment prior to developing osteoarthritis and (3) restoration of the patient's natural soft tissue laxity and envelope. A shim block assembly can be used in resecting the distal medial and lateral condyles to account for cartilage wear on the distal condyles from osteoarthritis. The shim block assembly can include a plurality of shims, and each shim can be attachable to or integral with a reference block. At least one of the plurality of shims can have a medial portion with a thickness different from a thickness of a lateral portion of the shim. The shims need not be joined together as a single medial/lateral component but may be independent of one another.

  • Patent number: 10105242
    Abstract: An adjustable spacer instrument, kit of parts and surgical methods of use in a knee arthroplasty procedure are described. The adjustable spacer comprises a first member having a substantially planar upper surface and a second member having a substantially planar lower surface. An angular adjustment mechanism is interposed between the first member and the second member, and is operable to adjust the degree of tilt between the upper surface and the lower surface. A releasable lock is provided which can maintain the degree of tilt. The spacer instrument can be used with the knee in extension or flexion to allow various cuts or re-cuts to be made to the tibia or femur while the ligaments are in balance or to balance the ligaments.

  • Patent number: 10028800
    Abstract: A thickness gage including a transparent measurement tube configured to receive and be slidingly engaged over a tubular shaft of a retrograde reamer. The tubular shaft has linear graduation marks on its surface for identifying linear measures for use in measuring a thickness of a bridge bone gap. The linear graduation marks are located on the tubular shaft surface such that at least some of the linear graduation marks can be observed through the transparent measurement tube. Each linear graduation mark, when aligned with a proximal end of the measurement tube, provides a linear measure of the distance between a distal end of the measurement tube and a cutting member of the retrograde reamer positioned so that its central axis is disposed at a non-zero angle relative to a longitudinal axis of the tubular shaft. Such a distance corresponds to the thickness of the bridge bone gap.

  • Patent number: 9962200
    Abstract: A prosthetic joint is secured to the bones forming the original joint by utilizing strictly mechanical fasteners, for example, a threaded rod engaging a tapped intramedullary canal. Cross locking members may be provided. The need for bone cement is avoided. The prosthetic joint may be used to replace one end of one bone forming the joint, utilizing the naturally occurring end of the other bone. Alternatively, both bone ends may be replaced with prosthetic joint portions. The decision to replace one or both bone ends may be made mid-surgery. The prosthetic joint portions are secured together utilizing ligament reconstruction members made from portions of the patient's tendons or allograft tendons. A bearing forming the interface between the two joint portions is designed to wear in order to protect the remaining components from wear, and to be easily replaced in relatively simple future surgeries.
