  • Patent number: 10806497
    Abstract: Bone compression systems for internal fixation of bone portions include one or more spring washers having ultra high load capacity and ultra low displacement to close diminution gaps that develop in a discontinuity between the bone portions after fixation. The spring washers, individually or in stacks of up to four, provide installation loads between 1500 N and 4000 N. After closing diminution gaps, the spring washers or stacks provide sustained loads between 1000 N and 3000 N which stabilize the bone portions sufficiently to permit early load bearing. The sustained loads correspond to sustained average local bone stress just below the bone growth trigger threshold stress. The additional loads of early load bearing will create average local bone stress above the bone growth trigger threshold. By bone stress repeatedly passing through the bone growth trigger threshold stress, bone healing is optimized.

  • Patent number: 10806472
    Abstract: Embodiments of the present disclosure are directed to instrumentation that facilitate coracoid-glenoid fixation in Latarjet procedures. For example, a single instrument, a coracoid resection tool, may be provided/utilized to prepare a coracoid bone graft for size, flatness, and hole drilling. A glenoid drill guide may further be provided/utilized that uses sized offsets for placement of the coracoid graft flush with the glenoid. Further embodiments of the disclosure are directed to corresponding methods that employ this instrumentation. For example, a surgeon may employs the coracoid resection tool as a guide to plane the inferior coracoid surface that will serve as the coracoid graft surface. The coracoid resection tool may further guide the placement of coracoid holes along the length of the coracoid and orient the holes approximately perpendicular to the planed coracoid graft surface. For example a proximal coracoid hole may be positioned towards the proximal end (i.e.

  • Patent number: 10786360
    Abstract: A prosthesis for implantation in a de-nucleated intervertebral disc includes a fiber ring-like layer which encloses a polymeric layer to create an annular space. The annular space is inflatable with an in-situ curable liquid polymer and forms an interior cavity. The annular space may be expanded uniformly or differentially to be tailored to the needs of a particular vertebral segment and to achieve optimal disc space width and angle, thereby stabilizing the segment while preserving normal motion of the vertebral segment. The interior cavity provides a void that allows inward deformation of the implant during weight bearing activities and bending. The prosthesis can be elastically deformed through axial elongation to a reduced profile to load into a delivery cannula using pulling techniques.

  • Patent number: 10765457
    Abstract: An orthopedic connection assembly is described that comprises a housing member for receiving an implant that is operably connected to a receiving member for receiving an anchor member. The connection assembly is configured to have a locking mechanism that secures and fixes the relative orientation between the implant and the anchor member. The connection assembly can comprise a plate member receivable within the housing member. When a securing member such as a set screw is introduced downwardly into the housing member to secure the implant, the securing member applies a lateral force to the plate member, which presses against an interference member within the receiving member. The interference member presses against the anchor member, such that the anchor member is fixed in a position relative to the implant.

  • Patent number: 10765465
    Abstract: A bone plate system for securing a plurality of bones is provided including a plate member, a locking device of the bone plate, and a surgical cable having a trailing end for being connected to the bone plate and a leading end for being advanced around the bones and into the locking device. The surgical cable may be tensioned to approximate the bones, urge the bones together, and seat the bone plate against the bones. The locking device may be reconfigured to a locked configuration to fix the bone plate to the surgical cable. The bone plate further includes a plurality of throughbores for receiving bone anchors that rigidly fix the bone plate to the bones. The bone plate system utilizes the tensile strength of the surgical cable and the rigid fixation between the bone anchors and the bone plate to resist relative movement of the bones.

  • Patent number: 10751099
    Abstract: A bone plate has a through-hole that extends from an upper side to a bone-side underside of the bone plate. A lip is formed in the through-hole, which lip projects from the lateral surface of the through-hole and extends in the circumferential direction of the through-hole. The lip extends over part of the circumference of the through-hole. In a circumferential section of at least 120° that lies opposite the lip, the lateral surface is free of a lip. Material is reshaped only to a lesser extent compared to a lip that extends over the entire circumference of the through-hole. The risk of complications occurring due to deposited particles is reduced.
