A medical device that may include a main body and a plurality of hooks. The main body includes a length extending along an axis between first and second ends. The main body may be deformable such that the axis forms an arch shape corresponding to a shape of a mandibular jaw or a maxillary jaw. The main body may include a plurality of sections each having first and second edges defining a first width and a plurality of openings disposed between the first and second edges and extending through a thickness of the main body. The main body may include a plurality of recessed portions defining a second width disposed between adjacent ones of the sections. Each of the hooks may extend from a corresponding one of the sections.

A bone stabilizing plate includes two plate portions, each affixable to bones of a patient, the plate portions telescoping together with mating rails and grooves. A limiter associated with one of the plate portions sliding engages one a catch associated with the other of the plate portions, when the plate portions are telescoped together, and resists stops telescoping when the plate portions are telescoped a predetermined distance apart. Once the limiter and catch are engaged, the plate portions enable imposition of a minimum compressive force between bones connected to the plates. The limiter is resiliently positioned to deflect into a relief formed in its respective plate portion. A groove positioned proximate the catch enables free telescoping motion limited by the engagement of the catch and limiter, whereby the minimum compressive force between bones is maintained, and Wolfe's Law may apply.

One aspect of the disclosure relates to an extramedullary distraction and compression system. The extramedullary distraction system includes: a housing configured to be attached to a bone at a first location, the housing having a magnet and a lead screw positioned therein, wherein the lead screw is coupled to the magnet such that rotation of the magnet causes rotation of the lead screw, at least one retainer clip disposed around the lead screw; a rod configured to be attached to the bone at a second location and configured to interact with the lead screw such that, upon rotation of the lead screw, the rod distracts or contracts relative to the housing.

A device for positioning an orthopaedic fixation device includes: a compression attachment mechanism; a fastener guide coupled to the compression attachment mechanism; and a spring member disposed in the fastener guide.

A connectable locking plate assembly comprises a locking plate unit, a connection unit, and a locking component. The locking plate unit comprises multiple interconnecting fixing parts. The connection unit comprises multiple interconnecting positioning parts, and at least one of the positioning parts has an assembly recess. One of the fixing parts is inserted into the assembly recess. The locking component is mounted through the screw connecting hole on the connection unit and is screwed into the screw setting hole of the locking plate unit. Therefore, the connectable locking plate assembly can be assembled into an appropriate structure by assembling the locking plate unit, the connection unit, and the locking component to meet the sizes and outer shapes of the bones at the fracture site. Therefore, the assembly can increase the fitting and fixing effect to the bones, and can enhance convenience during assembling.

An implantable fixation device for rejoining opposed portions of a separated bone. The device including two corresponding plates that are configured to be aligned and coupled to a bone, such as a sternum, pre-resection of the bone or prior to cutting/separating the bone. The placement of the corresponding plates provides a gap between the edges of the plates that face one another allowing for and guiding a cutting tool for separating the bone. After the bone has been cut and the desired surgical procedure performed, the plates also assist in realigning and fixation of the bone portions. At least one plate includes a ratchet mechanism that is configured to tighten a locking element and draw the two plates together and into alignment with one another.

Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a plate that is seated between the receiver member and the rod and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a hook that extends out from the receiver member to hook onto an anatomical structure or another implant to augment the fixation of the assembly's primary bone anchor. Surgical methods using the bone anchor assemblies described herein are also disclosed.

Implants, systems and related methods for correcting bunions are disclosed. The implants, systems and methods may include a first bone engaging implant configured to couple to a first bone, and a second bone engaging implant configured to couple to a second bone that is adjacent the first bone. The implants, systems and methods may further include a flexible cable member extending between the first and second implants that allows motion between the first and second implants but for movement of the first and second implants away from each other. The length of the cable member may draw the first bone towards the second bone and decrease an angle formed between therebetween. The cable member may be rigidly or slidably coupled to the first and second implants.

A method of changing a bone angle includes creating an osteotomy between a first portion and a second portion of a tibia of a patient; creating a cavity in the tibia by removing bone material along an axis extending in a substantially longitudinal direction from a first point at the tibial plateau to a second point; placing a non-invasively adjustable implant into the cavity, the non-invasively adjustable implant comprising an adjustable actuator having an outer housing and an inner shaft, telescopically disposed in the outer housing, and a driving element configured to be remotely operable to telescopically displace the inner shaft in relation to the outer housing; coupling one of the outer housing or the inner shaft to the first portion of the tibia; coupling the other of the outer housing or the inner shaft to the second portion of the tibia; and remotely operating the driving element to telescopically displace the inner shaft in relation to the outer housing, thus changing an angle between the first portion and second portion of the tibia.

The present inventions relate to a system and method for altering growth of bones. More precisely, the system is an orthopedic apparatus for correcting rotational deformities and limb length discrepancies. A system of cable-couplings with linking members is used, the linking members being posts or screws traversing bones. Due to the flexibility and adaptability of the system and its components, the cable-coupling members may be installed at varying angles and locations while allowing for growth arrest or rotational corrections of said bones. A method to limit growth using cable-couplings systems is also provided.
