The invention comprises a medical implant system with implant having a fastener hole for a fastener and further including a fusion screw, positioned to avoid interference with the implant fastener. The medical implant system also includes a guide that is mounted in the fastener hole and from an edge of the implant which provides for defined adjustability for angulation, and optionally depth, to allow for placement of the fusion screw so as to avoid impingement with the implant and the fasteners that secure it in place. The invention also relates to a method of surgery using the system.

Devices, systems, and methods for bone stabilization, especially proximal humeral stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion. The stabilization system may include an intramedullary nail having an upper portion and a lower portion extending from the upper portion, the upper portion and the lower portion including a plurality of holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and/or one or more of the plurality of holes in the intramedullary nail and into the bone. The plate and nail may each be used alone or in combination together to stabilize a fracture in a long bone, such as a humerus.

A tether assembly may be attached to a bone to correct a rotational deformity. The bone may have a growth plate that separates a first section of the bone from a second section of the bone. The tether assembly may have a tether member with a first end, a second end, and a central portion extending between the first end and the second end. The first end may have a closed outer wall that defines and fully bounds a first aperture. The second end may have an open outer wall that defines and partially bounds a second aperture. The open outer wall may define a slot in communication with the second aperture. The first and second ends may be securable to the first and second sections of the bone via coupling members inserted through the first and second apertures and anchored in the first and second sections, respectively.

A bone plate incorporating a length adjusting elongate hole formed in a shaft portion thereof, along with corresponding methods of use. In one embodiment, the length adjusting elongate hole is configured to receive one or more bone fixation devices (e.g., bone screws). In use, the bone fixation device positioned within the length adjusting elongate hole may be partially loosened, without removal, to enable the patient's bone to be adjusted (e.g., loosening the bone fixation device within the length adjusting elongate hole allows the surgeon to adjust the position of the patient's bone, and hence the bone fixation device coupled thereto, relative to the bone plate). Once properly adjusted, the bone fixation device positioned within the length adjusting elongate hole may be retightened. In various embodiments, the length adjusting elongate hole is configured so that, in use, each of the plurality of bone fixation openings remains available to a surgeon.

An orthopedic instrument for manipulating (e.g., compressing or distracting) one or more patient's bone fragments is disclosed. In one embodiment, the orthopedic instrument includes forceps having first and second arms and first and second handles, respectively. Each arm including a coupling mechanism for selectively engaging removable tips or bell housings. Each tip or bell housing including a first end arranged and configured to mate with a fastener hole or opening formed in a bone plate, a second end arranged and configured to receive a head portion of a bone fastener, and an intermediate portion arranged and configured to couple to the coupling mechanism of the first and second arms. In addition, the orthopedic instrument may include a force sensing mechanism or gauge arranged and configured to measure an amount of force being applied across the bone fracture.

Devices, systems, and methods of bone stabilization. The bone stabilization system includes a bone plate having an upper surface and a lower surface configured to be in contact with bone, the bone plate having an opening extending from the upper surface to the lower surface. The opening is configured to receive a fastener, which may be either a locking fastener or a compression fastener. The locking fastener has a threaded head portion configured to engage and lock to the bone plate, and the compression fastener is configured to dynamically compress the bone.

Devices, systems, and methods for bone stabilization, especially proximal humeral stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion. The stabilization system may include an intramedullary nail having an upper portion and a lower portion extending from the upper portion, the upper portion and the lower portion including a plurality of holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and/or one or more of the plurality of holes in the intramedullary nail and into the bone. The plate and nail may each be used alone or in combination together to stabilize a fracture in a long bone, such as a humerus.

Bone plates for engaging bone members are described herein. The bone plates can receive one or more screws to secure the bone plates to an underlying bone member. The one or more screws can be inserted into bone plate holes that can be considered locking or non-locking. The bone plates described herein can have particular combinations of locking and/or non-locking holes. The bone plates can include features that accommodate the underlying anatomy of different types of bone, such as the condylar region of a femur.

Disclosed is an osteosynthesis device including at least one fixation pin suitable for being implanted in a bone material so as to ensure an at least partial reduction of a bone fracture, which osteosynthesis device includes a locking unit designed to lock in position the fixation pin implanted in the bone material. The locking unit can include: a support structure provided with a unit that enables its fixing on the bone material, and including a locking aperture suitable for being passed through by the fixation pin; and a clamping designed to be fitted in the locking aperture and to come into abutment against a part of the fixation pin in order to ensure its locking in position.

A method for stabilizing a cervical spine segment includes inserting a respective uncinate joint stabilizer into each uncinate joint along a medial-to-lateral direction starting from intervertebral disc space of the cervical spine segment, and securing each uncinate joint stabilizer to the respective uncinate joint. A system for stabilizing a cervical spine segment includes a pair of uncinate joint stabilizers, each (a) elongated along a lengthwise dimension and configured for placement in the respective uncinate joint with the lengthwise dimension substantially oriented along an anterior-to-posterior direction of the cervical spine segment, (b) having height configured to define spacing of the respective uncinate joint, (c) and including a tapered portion for interfacing with superior and inferior surfaces of the respective uncinate joint and to enable insertion of the uncinate joint stabilizer into the respective uncinate joint from intervertebral disc space of the cervical spine segment.
