An implant inserter is adapted to secure and facilitate insertion of a surgical implant. The implant has an inserter attachment interface having a narrow external opening at a surface thereof and a broader internal opening. The implant inserter includes a handle and an inserter shaft. The implant inserter also includes a pair of flexible tabs extending from a distal end of the inserter shaft with laterally extending protrusions adapted to extend into the broader internal opening and an expansion shaft adapted to selectively extend between the flexible tabs whereby the expansion shaft prevents flexion of the flexible tabs such that the laterally extending protrusions secure the surgical implant, and whereby when the expansion shaft does not extend between the flexible tabs, the flexible tabs can be flexed inwardly to cause the laterally extending protrusions to have a narrower profile that is able to be passed through the narrow external opening.

An orthopedic implant with an inferior portion having a tibia contact surface configured to extend over a tibia; a superior portion opposite to the inferior portion having a tendon contact surface configured to change a position of a patellar tendon by lifting or tilting the patellar tendon when the curved surface of the first portion is engaged with the tibia; and a fixation mechanism adapted to attach the orthopedic implant to the tibia, the orthopedic implant being further configured to change shape from a first configuration to a second configuration in response to a load applied between the tendon contact surface and the tibia contact surface. The invention also addresses corresponding methods.

A method of treating a hip joint of a human patient using a pelvic drill comprising a driving member, a bone contacting and an operating device for operating said driving member. The method comprise the steps of cutting the skin of the human patient, dissecting an area of the pelvic bone on the opposite side from the acetabulum, creating a hole in said dissected area using said pelvic drill, said hole passing through the pelvic bone and into the hip joint of the human patient, and providing at least one hip joint surface to the hip joint, through said hole in the pelvic bone of the human patient. In one embodiment the method includes inserting a needle or tube like instrument into the patient's body for filling a part of the patient's body with gas and thereby expanding a cavity within the body.

Disclosed herein are methods and devices for distracting adjacent vertebrae during surgical procedures for implanting spinal prostheses. In an exemplary embodiment, a distractor is disclosed that maintains the empty space between adjacent vertebrae following a discectomy, and that can removably mate with other surgical instruments, such as, for example, a filler bar, an implanting tool, or a funnel. In other embodiments of the present invention a distractor is disclosed having various features to assist in implanting a spinal prosthesis, such as, for example, an angled distal end and/or an expandable paddle. In another embodiment of the present invention, an articulating inserter is disclosed. Moreover, various implants and funnels are also disclosed herein.

Expandable spinal implants and drivers connected by a bendable joint are disclosed. The flexible connector allows the implant and driver to move to different angular orientations with respect to each other, and to apply rotational force or torque from the driver to the implant and its expansion mechanism. During insertion of an implant into the desired position, the driver may be oriented in the same or different direction than the long axis of the implant. After the spinal implant is placed in the desired position, the driver is used to expand the implant in selected dimensions.

A surgical instrument for operating hip joint osteoarthritis in a human patient is provided. The hip joint comprises an acetabulum, being a part of the pelvic bone, and a caput femur, being the proximal part of the femoral bone. The surgical instrument is adapted to assist in the operating of the hip joint osteoarthritis from the abdominal side of the pelvic bone of said human patient.

A hip prosthesis device including a femoral stem, the femoral stem including an elongate stem sleeve having a blind hole extending in a longitudinal direction and a hole opening at an upper frontal end of the stem sleeve; a stem core having an elongate stem shaft inserted in the blind hole and slidable in the longitudinal direction, a neck having a lower neck portion and an upper neck portion, a lower end of a lower neck portion attached to an upper end of the stem shaft, the upper neck portion attachable to a femoral head; a shock absorber mechanism operatively provided between the stem shaft and the stem sleeve to act against a downwardly directed longitudinal sliding motion of the stem shaft relative to the stem sleeve; and a closure cap positioned to close the hole opening with a through hole which the neck extends with its lower neck portion.

The present disclosure includes prosthetic devices, including implants for joints and external prosthetics. The prosthetic devices allow for full articulation of the joint, while absorbing impact of the components during normal use that will reduce wear on the device components and prolong life. The device may include a bone implantable component and a bearing component having an articulation surface that is sized and shaped to substantially mate with at least a portion of the bone implantable component and a damping mechanism that includes a contact member disposed at least primarily inside a cavity; a biasing member biasing the contact member toward an upper aperture of the cavity and means for capturing the contact member within the cavity.
