A T-shaped plate for osteosynthesis, has at least three first attachment holes (124) and second attachment holes (113) including a curved linkage area (13). The epiphysis portion has a recess (34) with a curved profile from one end to the other of the T-bar when viewed from the top, and a curved profile when viewed from the side, and the diaphysis portion is straight and rigid. The plate is non-deformable at normal temperatures. The leg of the T has a rounded inner surface (56). The linkage area (13) has an S-shaped longitudinal cross-section, the ends (132, 133) of which that are adjoined with the bar and leg of the T, respectively, are substantially parallel to one another.

The present disclosure relates to a system comprising a dynamic locking bone plate and screw that provide a plate and screw complex for fracture fixation. The plate comprises a plurality of screw holes, each screw hole adapted to receive a screw. The screw threads allow for insertion into bone with compression of the plate to bone and the four male components on the screw head allow for the screws to be locked into place in the plate once they interact with the female components of the plate. The screw locking heads will come in two form, one plush fit to the locking plate and the other offset to allow some movement in the screw plate complex. On the under surface of the plate, the plate comprises a raised area or protrusion defining the bone to plate contact surface. The area between adjacent screw holes is adapted to allow for customisation by the surgeon intra-operatively for optimal fracture fixation. The screw head comprises a tapered shoulder to allow for compression at the fracture site if placed in an eccentric position.

According to an aspect, a preoperative planning method for a high-tibial knee osteotomy procedure is provided. The method includes: a) constructing a 3D model of a patient's bones; b) analyzing the 3D model to select a desired correction angle to apply to the patient's tibia bone to adjust a mechanical axis thereof; c) determining surgical steps required to apply the desired correction angle to the patient's tibia bone; d) designing a patient-specific guide to guide generic surgical tools in performing the surgical steps, the patient-specific guide being designed to conform to the anatomy of the patient's bones based on the 3D model; and e) manufacturing the patient-specific guide designed in step d). A corresponding kit, system and computer readable medium for performing the method are also provided.

The present disclosure discloses a fracture repair device realizing transition from mechanical fixation (association of osteosynthesis, AO) to biological fixation (biological osteosynthesis, BO), including: a bone repair instrument, wherein auxiliary components are arranged at positions, close to a repaired bone surface, of the bone repair instrument, and each auxiliary component is made of a degradable metal material or a composite material thereof or a degradable polymeric material. The device of the present disclosure only has the advantages of AO rigid mechanical fixation, but also can effectively improve the defects of bone disconnection, fixed segment osteoporosis, re-fracture after defixation, etc., frequently occurring under AO rigid mechanical fixation, realizing transition from mechanical fixation (association of osteosynthesis, AO) to biological fixation (biological osteosynthesis, BO) during bone fixation or repair.

A plate for securing two bone segments in a tibial plateau levelling osteotomy procedure having a body with an elongate distal portion and a proximal portion extending laterally and a plurality of apertures for receiving fixing means wherein at least two of the apertures are adapted to receive fixing means and at least one of the said apertures is adapted to receive a removable plug which extends proud of the bone-facing surface. One of the apertures has a camming surface configured such that upon insertion of the fixing means the bone fragments are urged together thereby promoting healing without deleterious compression of the surface of the bone.

A fastener for use with a bone plate having a spring loaded fastener locking clip includes a cylindrical head portion having an outer periphery and defining a longitudinal axis, a threaded body portion configured for insertion through a fastener receiving aperture of the bone plate, an annular shoulder formed between the cylindrical head portion and the threaded body portion, the annular shoulder having an outer periphery, and at least one anti-rotation flange extending between the outer periphery of the cylindrical head portion and the outer periphery of the annular shoulder.

An orthopaedic implant includes a bone screw having a surface with a plurality of threads extending from the surface and a plurality of holes formed through the surface and located between the threads. The bone screw defines an inner chamber that is in communication with the holes. A fixation material is placed in the inner chamber and configured to chemoattract tissue surrounding the bone screw following implantation to fill in at least some of the holes.

An orthopedic spacer assembly can include a bone plate and a spacer. The bone plate can include a first end portion and a second end portion, the second end portion defining a plurality of anchor openings. The spacer can have a c-shaped body and can include a central bore extending through a thickness of the spacer. The spacer can be disposed between the bone plate and a subject's bone such that the central bore of the spacer aligns with an anchor opening of the plurality of anchor openings.

Implants, systems, and methods of reverse dynamization. The implants, such as expandable spinal implants, bone plates, and intramedullary nails, are securable to bone. The implant may have a moveable component creating a semi-rigid configuration to allow for micro-motion of the bone for a period of time. The moveable component is changeable, for example, based on material properties, change of state, or mechanical or electrical operation, to a static condition creating a rigid configuration to prevent subsequent movement of the bone. The reverse dynamization implants may be used to accelerate bone healing and obtain superior bone fracture healing.

A bone plate includes a pair of lobed portions and a central linking portion extending between the pair of lobed portions. The pair of lobed portions each include a through-hole extending from an upper surface to a lower surface and configured to receive a fastener. Each of the lobed portions has a cross-sectional thickness, in a plane extending along a longitudinal length of the bone plate and between the upper and lower surfaces, that continuously decreases in a direction extending away from the central linking portion to a respective end of each lobed portion. The bone plate has a maximum thickness where each lobed portion joins the central linking portion, the maximum thickness being approximately 1.5-2.3mm. A minimum thickness of the central linking portion is approximately 1.3-1.7mm.
