The invention relates to a longitudinal bone implant with a substantially circular cross-sectional profile, comprising a front section having a front end and a shaft section having a rear end, wherein the front section comprises at least three longitudinal groove-like cut-outs extending in the axial direction of the front section and opening towards the front end of the implant, circumferentially alternating with at least three longitudinal, radially protruding ribs extending in an axial direction, wherein the ribs have an increased cross-sectional width in the section radially more distant to the central longitudinal axis of the implant as compared to the width in a section radially closer to the central longitudinal axis of the implant. Furthermore, the invention relates to uses of the implant and methods that employ the implant.

This invention relates to a coupling for an orthopaedic device. Also disclosed in an orthopaedic device comprising a coupling of the invention and method for the use of the orthopaedic device. The orthopaedic device finds utility as a bolt apparatus for fixation of bones such as fractures of the femur, although it may be used in any suitable bone.

A method of joint replacement including forming one or more arthroscopy portals adjacent a hip joint that includes, a femur with a femoral head and a pelvis with an acetabulum socket, inserting a hemiarthroplasty cup, having a cup inner surface and a cup outer surface, between a femoral head outer surface of the femoral head and an acetabulum outer surface of the acetabulum socket, wherein at least one of the femoral head outer surface and the acetabulum outer surface are unreamed.

The present invention relates to orthopaedic implants having a fenestrated hollow shell and a biologic core. These design features provide an improved interface between the implant and the surrounding tissue, aiding fixation, and provide a vehicle for applying new bone healing and enhancing modalities, such as gene therapy, tissue engineering, and growth factors.

The current invention features a rod screw for medical application that can be configured and used to fixate fracture of bones varying in shape and dimension, and treating maladies such as scoliosis, and securing an implanted device, to tissue such as bone. This is achieved by designing a flexible rod screw with a mechanism to lock the configuration in a rigid state. In an embodiment, a bone-fracture fixation device, such as a rod screw, includes a flexible body, a plurality of flexible members, and first and second interfaces. The flexible members are disposed longitudinally within the flexible body, such that the flexible body is rigid when the flexible members are fixed into position. And the first and second interfaces are respectively coupled to the flexible body, each of at least one of the first and second interfaces including a respective at least one hole each configured to receive a respective attachment member configured to engage a bone.

A bone implant includes a rod having an aperture extending entirely through the rod. The aperture is to receive a fastener to couple the rod to a bone of a patient. The bone implant also includes a light source disposed on the rod. The light source is to emit light onto a portion of the bone adjacent the rod to at least one of stimulate bone growth or reduce bone loss.

Disclosed is a bone fixation device of the type useful for connecting two or more bones or bone fragments together or connecting soft tissue or tendon to bone. The device comprises an elongate body having a distal anchor thereon. An axially moveable proximal anchor is carried by the proximal end of the fixation device, to accommodate different bone dimensions and permit appropriate tensioning of the fixation device. A sleeve can surround at least a portion of the bone fixation device to promote bone in-growth with or at the bone joint or fracture to facilitate fusion of the bone segment.

A system and method for forming a hip implant offering minimal invasiveness is described. The system comprises means for positioning the implant under optical and X-ray control, an implant and an applicator for screwing and expanding the implant. The implant includes an insert body and an expansion tube with cut-outs and slits defining legs. The legs expand radially through windows in the insert body when the expansion tube is pushed against the sloped distal portion of the insert body. The expansion process may be ensured by using an anti-rotation device to prevent the insertion tube from rotating within the insert body. Applicator and implant are provided with means preventing cold welding during the implantation process.

The invention features bone drill guides, sleeves, and methods of use thereof in inserting hardware into bones, in particular to repair bone defects. The bone drill guides are designed to seat firmly against bone while allowing translational, rotational, and angular movement during an operation. The bone drill guides also allow for insertion of multiple devices, such as guide wires, into bone at defined and constrained relative position.
