A minimally invasive intervertebral implant includes a circuitous body defining a luminal axis extending longitudinally therethrough. The circuitous body includes proximal and distal ends oppositely disposed along a lateral axis of the circuitous body. Each of the proximal and distal ends includes an aperture disposed therethrough such that the circuitous body includes a first configuration wherein the proximal and distal ends are at a maximum separation and a second configuration wherein the proximal and distal ends are closer together than in the first configuration.

A method of, and apparatus for, directing an elongate flexible component with a length through a part of a human body. The method includes the steps of: obtaining an apparatus having an elongate body with a length between axially spaced leading and trailing ends and a notch through a peripheral surface of the elongate body; directing a midlength part of the elongate flexible component into the notch to place the elongate flexible component into an operative position on the apparatus; and with the elongate flexible component in the operative position, advancing the elongate body through the part of the human body and thereby causing a portion of the elongate flexible component to be drawn by a drawing surface on the elongate body through the part of the human body.

The invention relates to a bone anchor for triangular iliosacral osteosynthesis. The bone anchor includes an ilium screw having a first longitudinal direction and an iliosacral screw having a second longitudinal direction. The ilium screw, in a thread-free portion, has a preferably elongated-hole-like through-opening transversely to the first longitudinal direction, and the iliosacral screw has such a smaller outer diameter in relation to the ilium screw that the iliosacral screw can be guided through the through-opening and can be screwed proceeding from the ilium into the sacrum, through the ilium screw.

A bone fastener includes a shaft. The shaft includes a wall that defines a longitudinal cavity and a plurality of openings in communication therewith. The openings are disposed in axial alignment along the shaft and the wall is closed exclusive of the openings. In some embodiments, systems, spinal constructs, surgical instruments and methods are disclosed.

One aspect relates to a bone cement applicator having a cartridge with an interior, a cartridge head with a delivery opening, a mixing member which is movable in the interior with a mixing rod. A delivery plunger is arranged in the cartridge and is mounted in the interior and is pressable in the direction of the delivery opening. The delivery plunger rests with an outer cylindrical circumferential surface against an inner wall of the cartridge. A clamping element is arranged on the inner wall of the cartridge in the region of a back side of the interior. The clamping element projects out of the inner wall of the cartridge. The cylindrical circumferential surface of the delivery plunger is resiliently deformable by the clamping element in the direction of a central cylinder axis, such that the delivery plunger is clampable in place with the at least one clamping element on the back side of the cartridge.

A gap gauge is disclosed for facilitating an arthroplasty procedure on a first bone and a second bone of a patient. The gap gauge may include a first plate positionable in contact with the first bone, a second plate positionable in contact with the second bone. The second plate may be displaced from the first plate by a displacement. The gap gauge may further include a balance indicator configured to indicate a balance status between the first plate and the second plate and a pin guide. The pin guide is configured to couple to one of the first plate and second plate and includes a pin hole that is configured to guide a pin for insertion into the second bone. The pin can be used to couple a cutting guide to the second bone to resect the second bone to adjust the balance status.

A method is provided for determining the shape of a surgical linking device that is to be attached to a bony body structure such as the spinal column based on digitized locations of a plurality of attachment elements engaged to the bony structure. The method is implemented by a computer system through a GUI to generate an initial bend curve to mate with the plurality of attachment elements. The initial bend curve may be simplified based on user input to the GUI to reduce the number of bends necessary to produce a well-fitting linking device and may be altered to help obtain the goals of surgery.

Disclosed are bone screw drill targeting guides and methods for using such targeting guides that are useful in surgical procedures for correcting hallux valgus deformity.

A device for tensioning a surgical thread comprising: an elongated body having a tip portion adapted to be arranged in contact with a knot of a surgical thread wound about a patient's bone and a maneuvering member connected to the elongated body by a screw and nut mechanism configured to adjust the distance between said elongated body and said maneuvering member, said maneuvering member having respective coupling portions for coupling opposite ends of the surgical thread wound and knotted about the bone. The opposite ends of the surgical thread reversibly constrainable to the respective coupling portions in a use configuration of the device. The distance between the elongated body and the maneuvering member can be increased along a movement axis to tension the opposite ends so as to tighten the surgical thread about the bone. The tip portion has a groove shaped to receive at least partially the knot.

A bone material dispensing system is provided. The bone material dispensing system comprises a funnel having a proximal portion, the proximal portion comprising a top end and a bottom end, the top end opposite the bottom end, the top end comprising a surface having a protrusion configured to receive a locking member of a bone material dispensing device and the bottom end comprising a connector configured to secure the funnel to the bone material dispensing device. A bone material dispensing system comprises a pusher and a holder is provided. A method of dispensing bone material with the bone material dispensing system is also provided.
