The invention relates to the intramedullar nail fixation (13) of the femoral bone that is used in the field of orthopedics and traumatology, in particular, in the pediatric orthopedics field; Its features include the follows; Removal of many negativities in the treatments of femoral proximal area fractures seen in the child age group, young and old bone rotation surgeries, malunion, nonunion and deformities, and in order to make positive contribution to the healing processes of patients, the proximal femoral de-rotation nail (13), by which location can be fixed by turning in an angular way, and by which the operator can perform rotation as much as necessary by fixing rotation angle, and which is formed with the proximal component (1) and the distal component (2), which can perform rotational movement on each other and can fix its location, was developed.

The present invention includes a tibio-talar device for providing stabilizing support between a tibia and a talus including: a bone nail adapted to traverse the tibia and the talus, wherein the bone nail is curved such that it traverses the tibia and enters the talus at an angle, wherein the bone nail is angled from lateral to medial, wherein the bone nail is configured to provide for intra medullary fusion of the ankle without obstructing the subtalar joint, wherein the bone nail has openings are positioned along the length of the bone nail, and wherein the screw engages the bone nail to lock its rotation in relation to the tibia and talus and optionally for compression of two or more bones selected from tibia to talus, fibula to tibia, or fibula to talus,

The invention concerns a distal radius fracture fixation device for securing at least two fractured bone segments together. The device comprises: a body portion comprising at least two insertion channels each extending through the body portion and each being configured for receiving a bone fixation element therethrough; and an insertion device connection portion connected to the body portion, and for coupling a separate insertion device to the fracture fixation device. The insertion device connection portion is arranged to be decoupled from the body portion.

An intramedullary nail implant for positioning in a bone having a head and a shaft defining an intramedullary canal. The implant includes a distal portion having a shaft extending along a central axis and configured for positioning within the intramedullary canal. A proximal portion extends proximally from the distal portion. The proximal portion defines a contact surface which extends at least in part medially of the central axis such that it is configured to extend within a medial portion of the bone head. A method of implanting the nail is also provided.

An implant system for use in orthopaedic surgery for fixation of bone includes an intramedullary nail and a coupling member. The intramedullary nail includes a proximal portion defining a longitudinal axis. The proximal portion includes an axial bore defining an axis substantially parallel to the longitudinal axis of the proximal portion and a transverse bore configured to receive a bone fastener. The coupling member includes a through hole and is movably arranged within the axial bore of the proximal portion. Further, the coupling member includes a drive portion and a bone fastener engagement portion. The drive portion is in one variant non-rotatably coupled to the bone fastener engagement portion. The bone fastener engagement portion is configured to engage the bone fastener penetrating the transverse bore. In one variant the engagement is realized via an extended contact region.

The invention relates to nails used for ankle deformities and joint disorders characterized in that it comprises, in order to form an ankle arthrodesis nail (1) acting as a fixing nail passing through inside the canals of calcaneus, talus and tibia bones (19, 18, 17), providing a more rapid recovery and reducing the infection risk, at least three and at least two screw holes in lockable structure in its distal part and in its proximal part, respectively, arthrodesis nail (1) providing the closure of the inter-bone gap and an easier fusion by means of the compression effect during being fastened upon the bones, protrusions (15) extending from its proximal to its distal, and slit (12) or slits (12) at the proximal tip of the arthrodesis nail (1) to decrease the stress cracks that might occur due to the tip of the arthrodesis nail (1).

The present invention relates, in some embodiments thereof, to orthopedic implantable devices for treatment of periprosthetic bone fractures, the devices include an elongated cylindrical shaft extending between a distal end and a proximal end, wherein a proximal portion extends from the proximal end, the proximal portion sized and shaped to allow for an engagement with a distal tip of a preexisting bone implant, the proximal portion comprising at least one longitudinal slot extending from the proximal end and providing a relatively flexible proximal portion configured to mate with various sizes and shapes of preexisting bone implants.

A guide sleeve for use in anchoring a fixation member to an intramedullary nail and to bone includes a sleeve body that is elongate along a central axis and has an internal surface that defines a bore extending along the central axis to a distal end of the sleeve body. The sleeve body also defines a plurality of guide channels that are each recessed radially outwardly from the internal surface and each include a helical proximal portion and a linear distal portion that extends from the helical proximal portion toward the distal end. The linear distal portion is parallel with the central axis. The guide channels are configured to receive respective complimentary followers of an instrument for driving the fixation member through the bore and subsequently through the intramedullary nail and into the bone.

A spinal fixation device is provided including a modular head assembly and a bone screw. The modular had assembly includes a housing, an anvil, an insert, and a snap ring. The housing defines a proximal surface and an opposite, distal surface, and the proximal and distal surfaces define a throughbore therethrough. The anvil is configured to be slidably received within a portion of the throughbore. The insert defines a proximal surface and an opposite, distal surface, and the distal surface defines a first counterbore therein that terminates at a first annular surface. The first annular surface defines a second counterbore that terminates at a second annular surface. The snap ring is configured to be disposed within the first counterbore of the insert when in a first configuration, and within the second counterbore of the insert when in a second configuration.
