A surgical system includes a sleeve defining a passageway. An adapter is removably coupled to the sleeve. The adapter defines a channel. A delivery device includes a distal end positioned in a channel of the adapter. A bone fastener includes a head and a shank defining a cannula. A distal portion of the adapter is positioned in the shank such that the channel is in communication with a cannula of the shank. A plunger is movably disposed in a lumen of the delivery device. The plunger is configured to move a material through the lumen and the channel and into the cannula. Methods and kits are disclosed.

Pedicle-based intradiscal fixation devices, systems, instruments, and methods thereof. An implant for stabilizing an inferior vertebra and a superior vertebra may include a first member and a second member moveably connected to the first member. The implant may have a first, initial insertion orientation and a second, final implantation orientation different from the first, initial insertion orientation. The first member may be configured to be inserted through a pedicle of the inferior vertebra and the second member may be configured to engage bone of the superior vertebra in the second, final implantation orientation.

Pedicle-based intradiscal fixation devices, systems, instruments, and methods thereof. The implant or a portion thereof may be composed of a shape-memory material, which has a curved shape-memory orientation and a temporarily straight orientation. The implant may be configured to be inserted into a pedicle of an inferior vertebra, through the vertebral body of the inferior vertebra, and into the vertebral body of the superior vertebra to thereby stabilize the inferior and superior vertebrae.

A medical that is implantable into a human or animal body or being an augmentation device for strengthening human or animal hard tissue for subsequent implantation of a separate implant. The device includes a sheath element suitable of being brought into contact, during a surgical operation, with live hard tissue and/or with hard tissue replacement material. The sheath element has a, for example, generally elongate shape and a longitudinal bore defining a longitudinal opening reaching from a proximal end of the sheath element into a distal direction, and a plurality of holes in a wall of the opening. Further, the device includes a liquefiable element that is insertable or inserted in the longitudinal opening and at least partly liquefiable by the impact of energy impinging from the proximal side.

A bone anchoring element comprising a shaft (2) for anchoring in a bone, with a plurality of barb elements (7) arranged in at least one helical line around the shaft axis (M) is described, wherein said barb elements are elastically movable relative to the shaft. The bone anchoring element (1) is easy to press into a core hole bore in a bone. The barb elements (7) act in a similar manner as do the threads on a conventional bone screw and thus provide for depth positioning. Moreover, the barb elements at the same time secure the bone anchoring element and prevent it from sliding-out.

An expandable support device for tissue repair is disclosed. The device can be used to repair hard or soft tissue, such as bone or vertebral discs. A method of repairing tissue is also disclosed. The device and method can be used to treat compression fractures. The compression fractures can be in the spine. The device can be deployed by compressing the device longitudinally resulting in radial expansion.

The invention relates a system for implanting an implantable device in bone tissue, a processing unit for such system, a method of implanting an implantable device and a method of providing information for an implanting of an implantable device. In view of the finding that a fat content in cancellous bone is higher than a fat content in compact bone, the lipids fraction, which can be determined by optical means, e.g. spectroscopy, can be used to determine correct screw placement in healthy bone.

The present invention discloses a blade structure, a hip screw and a femur fracture treatment device. The blade structure's body has a centrally radially symmetrical cross section. The centrally radially symmetrical cross section has a plurality of centrally radially symmetrical sections, on each of the section at least a cutting slot and two blades formed at corresponding top ends of two sides of the cutting slot respectively are defined, and a projection of a top end of each blade is located on a bottom wall of an interior of the cutting slot.

A method and system for promoting the union of a bone fracture and/or fusion of bones across a joint space at a target region of a subject which may be accomplished by: inserting a surgical implant device at the target region; providing a guide member in the surgical implant device bore; sealing the surgical implant device bore distal opening and/or the surgical implant device bore proximal opening with the guide member; and positioning the guide member relative to the surgical implant device to provide for the guide member to be partially absent from the surgical implant device bore to allow the biomaterial and/or biologically active agents to extrude or diffuse from the activated apertures to the target region of the subject.
