A bone joint spacer has two endplates which have a bone engaging surface on one side, and ramps extending from an opposite side. A shaft has a threaded end, and another end which has ramp followers which mate with the endplate ramps of both endplates. A collar slides over the threaded end of the shaft, and also has ramp followers which mate with the endplate ramps of both endplates. A nut threads onto the end of the shaft and pushes the collar towards the ramp followers of the shaft. This movement causes the ramp followers to slide the ramp followers of the collar and the shaft against the endplate ramps, pushing the endplates apart. Two of these spacers can be combined by a link plate so that the spacers can be aligned or curved into a U-shape to be inserted into the body and positioned between bony surfaces, respectively.

A prosthetic intervertebral disc joint assembly for replacing at least a portion of an intervertebral disc between first and second adjacent vertebrae. A first component has an intervertebral portion insertable between adjacent vertebrae, with a bone-engaging side and a convex articulating inner side opposite the bone-engaging side. A second component engages the second vertebra and has a concave articulating surface. The first and second components each include a fixation portion for securing the component to the anterior side of the respective vertebra.

An apparatus for the treatment of canine or other animal hip pathologies, the apparatus (200) comprising a buffer (210) adapted to be disposed between a femur (10) and a hip socket (25), and a fixing means (250) adapted to fix the buffer to the femur.

A link (1) for connecting two loops of a flexible tension-carrying construct (2, 2a). It solves the problem of providing effective means to connect two anchor points (7, 7a), typically on bones articulating at a joint by the flexible tension-carrying construct.

An implantable orthopedic wedge can include a main body having a base portion and an apical portion, the apical portion including a first end. The main body can have a thickness that tapers along a perimeter of the main body from a first thickness at the base portion to a second thickness at the apical portion. The implantable orthopedic wedge can also include a fixation member coupled to the main body and configured to receive one or more anchoring elements to anchor the wedge to an implantation site.

A surgical guidance system (SGS) for performing a cruciate pivot osteotomy in canines to treat cranial cruciate ligament disease. The SGS comprises a guide, a jig, and a plate. The guide is first placed over the tibia until it interacts with specific anatomical features of the tibia, thereby marking the proper position for the jig to be placed. After the jig has been secured, a blade defines an osteotomy within a proximal portion of the tibia. A portion of the jig is then cranially rotated providing a rotational correction of the proximal tibia. A compressive force is then applied to the osteotomy by the jig. Next the multiplane locking plate is placed over the osteotomy as dictated by the features of the jig. After initially securing the plate into its correct position, the jig is removed and the plate is then secured to the cranial surface of the tibia.

A proposed treatment of arthrosis/osteoarthritis in a joint of a mammal or human patient involves deposing a liquid material on at least one damaged surface of the joint. To accomplish this, a reservoir (110) is provided, which holds a volume of a biocompatible material in liquid form outside of a body containing the joint (J) to be treated. A proximal end (P) of a tub e-shaped instrument (120) is connected to the reservoir (110), and a distal end (D) of the instrument (120) is inserted into the joint (J). The liquid material is fed through the instrument (120) to the distal end (D) for deposition on the at least one damaged joint surface.

The material is configured to assume a solid form under predefined conditions (e.g. when cooling off, or being exposed to a specific type of radiation). When the material has the solid form, it has a resistance to wear adapted to replace a worn out joint surface.

The present disclosure relates to a customized medical implant for attachment to and at least partly covering the natural femoral head of a hip joint of a subject. The medical implant includes a dome shaped shell having a height h, an inner equatorial shell radius r.sub.s, an orifice radius r.sub.o, a thickness t.sub.s at the equatorial line, and a thickness t.sub.t at the top of the dome. The implant is constructed such that one or more of the thickness t.sub.s, the thickness t.sub.t, the equatorial shell radius r.sub.s, the orifice radius r.sub.o and the shell height h are customized to the hip joint of the subject based on at least one 3D computed tomography image showing substantially the entirety of the natural femoral head and the acetabulum of said hip joint.

A novel and improved elbow prosthesis and method of implanting same including a novel aggregate prosthesis having a retaining system in conjunction with a set plate.

A low profile intervertebral implant for implantation in an intervertebral disc space between adjacent vertebral bodies of a quadruped. The intervertebral implant includes a plate and a spacer that extends from the plate. The intervertebral implant can define geometries that nest with complementary geometries of the vertebral bodies. Further, the plate can include fixation holes that extend along trajectories such that screws inserted through the fixation holes and driven into the respective vertebral bodies can purchase with dense cortical bone.
