A method for implantation of a locking member in a hip joint of a patient is disclosed. The method comprises; performing an operation in a hip joint surgically or arthroscopically, placing an artificial hollow caput femur surface mounted onto caput femur, placing a locking member for assisting in the fixation of the artificial caput femur surface with at least one extending portion adapted to clasp a portion of the caput and/or collum femur. The locking member comprises an element locking the artificial caput femur surface such that the caput femur remains clasped and restrained in said artificial caput femur surface.

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 creating a 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.

A method of treating a hip joint of a human is provided. The method comprises a step of dissecting an area of the pelvic bone, comprising at least one of the following: dissecting an area between peritoneum and the pelvic bone, dissecting an area between the pelvic bone and the surrounding tissue, dissecting an area of the pelvic region, and dissecting an area of the inguinal region, or, the method comprises at least two of the following steps: dissecting an area of the abdominal cavity, penetrating the hip joint capsule, dissecting an area between peritoneum and the pelvic bone, dissecting an area of the pelvic bone which comprises: dissecting an area between the pelvic bone and the surrounding tissue, or dissecting an area of the pelvic region, or dissecting an area of the inguinal region, and removing or penetrating the tissue surrounding the pelvic bone in the area opposite to acetabulum.

A knee arthroplasty system may have a femoral joint prosthesis with a femoral bone engagement surface with an anterior portion, a posterior portion, and a distal portion that connects the anterior portion to the posterior portion. A first femoral anchoring member may protrude from the distal portion, and may be connected to the anterior portion with a primary femoral web. A tibial resection guide may have a base member and a guide member with a slot that guides a cutting blade to resect the tibial plateau. The guide member may slide along an arcuate path relative to the base member.
摘要:
Some embodiments of the invention provide an apparatus that (1) delivers a fusion member between two vertebral bodies after at least a portion of the fibrocartilaginous disc between the vertebral bodies has been removed, and (2) affixes the fusion member to the vertebral bodies. In some embodiments, the apparatus includes (1) a fusion member that is delivered and positioned between the vertebral bodies, (2) a delivery mechanism that delivers and positions the fusion member between the vertebral bodies, and (3) an anchoring member that affixes the fusion member to the vertebral bodies.

A vertebral body replacement device includes a body member and a central rod member having two threaded portions and configured to be operatively associated with the body member. The device also includes a first end member and a second end member with the end members configured to threadingly engage the threaded portions of the central rod member. The body member and the two end members are further constructed to inhibit rotational movement of the two end members when the device is positioned within a space within a spine as the two end members will engage the adjacent respective vertebral bodies following rotational actuation of the central rod member causing the end members to move in an axial direction relative to the body member, thereby allowing the two end members to apply a force to the two vertebral bodies. A surgical instrument and method for using the device are also disclosed.
摘要:
A flexible space holder made of at least one biocompatible, rigid material having a tube-like body, with one or more flexible areas is described. The flexible space holder can be temporarily or permanently inserted into a human or animal. Furthermore, the flexible space holder can be surrounded by an elastomeric sleeve. Alternatively, an elastic core can be inserted into the center of the flexible space holder.
摘要:
Tissue spacer implants and surgical methods for inserting the implants are disclosed. The implants may include a first cylindrical body with an outer surface, an axially extending hole, and a first end, a second cylindrical body with an outer surface and an axially extending hole, and an adjustment member with an outer surface, an axial hole, and at least one helical slot. The adjustment member axial hole may be adapted to receive the first cylindrical body and the adjustment member may be configured to be inserted into the axially extending hole of second cylindrical body. The implants may also include a travel mechanism for engaging the first cylindrical body, adjustment member, and second cylindrical body along the at least one helical slot to maintain a space between two bodies of tissue.

摘要:
Intervertebral implant for mutual situating of adjacent vertebrae contains a cover (1) in a shape close to the rectangle, in which is fixed a driving mechanism. In a lateral wall (2) of the cover (1) a manipulative hole (3) is made. The cover (1) is equipped with one open seat (4). The driving mechanism composes situated in the seat 4 and anchoring in one of displaced vertebrae one rotational element (5) with an axis 6 mounted for an axial movement in lateral walls (2) of the cover (1) perpendicularly to the direction of the displacement of vertebrae against each other, cooperating with the connecting element (7). The rotational element (5) is equipped with anchoring latches 8 projecting over the height of cover's (1) walls (2) from the side contacting with one of displaced vertebrae and anchoring in this vertebrae. Anchoring latches (8) have got a form of paddles of equal dimensions and shapes. The connecting element (7), situated within the diameter of the manipulative hole (3) of the cover (1), cooperates with not visible on the figure separate driving tool. The connecting element (7) constitutes one shaped end of the axis (6) of the rotational element (5). The implant is equipped with two blockades of the rotation of the driving element. One of blockades of the driving mechanism has got a form of a pin (9a) situated within the diameter of the manipulative hole (3) of the cover (1) and cooperating with not visible on this figure recess in the axis (6) of the rotational element (5), whereas the second blockade of the rotation constitutes a latch 9b fixed to the cover (1) on the opposite side than the pin (9a), cooperating with the rotational element (5). The lower surface of one of lateral walls (2) of the cover (1) is equipped with anchoring latches (10) in a form of paddles, anchoring in the second of displaced vertebrae.
