A perforated sheath is anchored in a tissue opening with the aid of a tool, wherein the anchorage is achieved with the aid of mechanical vibration and a material which is liquefiable by the vibration. The tool includes a vibrating element and a counter element. Distal portions of both elements are introduced into the sheath to be in contact with each other at an interface. The vibrating element is connected to a vibration source and the vibrating element and the counter element are held against each other for effecting liquefaction of the liquefiable material at the interface. Under the effect of the force applied to the vibrating and counter element for holding them against each other, the liquefied material flows from the interface through the sheath perforation and penetrates the tissue.

Devices, systems, and methods for bone stabilization, especially volar distal radius stabilization. The stabilization system may include a bone plate having an elongated portion, an enlarged head portion, and a transition region connecting the elongated portion to the enlarged head portion, and the plate including a plurality of through holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and into the bone. The plate may be used to stabilize a fracture in a long bone, such as a radius.

The present invention is directed to devices for inserting bone staples into segments of bone. More specifically, embodiments of the present invention are adapted for accurately, selectively and simply providing for decompression of compression staples through application of a decompression force thereon, for placement of the legs of the decompressed compression staple in provided leg holes in adjacent bone segments while the compression staple remain decompressed, and for selective removal of the decompression force. In this respect, a staple inserter configured in accordance with an embodiment of the present invention is beneficial and useful in surgical procedure requiring bone tissue to join or rejoin with adjacent bone segments.

A vertebral fixation plate assembly for securing adjacent vertebral bodies is provided that is configured to distract or extend along its length, as well as provide multiple degrees of freedom between the fixation points and the vertebral fixation plate in order to accommodate different installation locations, as well as different surgical approaches. Methods of using the vertebral fixation plate assembly are also provided.

A bone plate assembly may include a bone plate with an obverse side, a reverse side, a fastener hole formed through the bone plate from the obverse side to the reverse side, a first draw hole formed through the bone plate from the obverse side to the reverse side, with a wire engagement surface, a fastener insertable through the fastener hole and into tissue, and a first wire insertable into the first draw hole, with a distal end anchorable in the tissue and a proximal end with a retention portion that is retainable in the first draw hole. The wire engagement surface may be oriented obliquely relative to a pilot hole formed in the tissue to receive the wire such that motion of the first wire through the first draw hole exerts a compressive force against the tissue.

The invention discloses an improved wedging cage within the sacroiliac (SI) joint and fixation screw(s). The wedging cage is adapted to be positioned between the sacrum and the lilac bone (e.g., the sacroiliac joint), and the wedging cage is effective to receive one or more fixation or axial screws to fasten the wedging cage and secure the wedging cage to the adjacent pelvic bones to provide a combination effect of fusion and/or fixation. Accordingly, the improved fixation screw assemblies promote flexibility and adaptability due to the adjustable head being movable to a locked and unlocked position relative to the screw body when implanted onto a substrate.

The present disclosure provides devices, systems and methods of bone fixation. The disclosed devices, systems and methods facilitate secure fixation of first and second bone segments, such as to promote fusion thereof. The devices may include at least one bone engagement projection extending from an engagement surface of a plate portion for implantation into the first bone segment. A portion of the plate portion spaced from the at least one bone engagement projection may include at least one bone fixation aperture. The least one bone fixation aperture may allow for a one bone engagement projection to be inserted therethrough and into the second bone segment to affix the plate portion to the second bone segment. In some embodiments, the at least one bone fixation aperture may be a compression slot.

Disclosed are laminoplasty devices and systems, kits that include such laminoplasty devices or systems or components thereof; and methods of assembling and using such laminoplasty devices and systems. In particular, articulating laminoplasty devices are provided that allow lamina plates to be adjusted angularly and transitionally with respect to a cage connecting the lamina plates. Also provided are laminoplasty plates that are configured so as to be assembled with a bone graft housing, and which provide an opening configured to facilitate bone graft insertion into the housing. Further provided are expandable laminoplasty fixation systems that include a lateral mass plate, a lamina plate and a set screw that when screwed and unscrewed, allows one to contract and expand the plates with respect to one another.

An orthopedic device for repairing a portion of a body comprises an orthopedic plate and a tissue protector. The orthopedic plate is configured to attach to at least one bone. The tissue protector is securely attached to the orthopedic plate and configured to at least partially detach from the orthopedic plate after a force is applied to the tissue protector. The tissue protector includes a thinned region at a portion of the tissue protector proximate to the orthopedic plate. A method of repairing parts of a body with an orthopedic device having an orthopedic plate and a tissue protector securely attached to the orthopedic plate comprises placing the orthopedic plate on at least one bone; fastening a fastener into the tissue protector and then the orthopedic plate; and detaching the tissue protector from the orthopedic plate after the fastener is completely fastened into the tissue protector and the orthopedic plate.

A calcaneum translation plate having two end portions, i.e. a proximal anchoring portion and a distal fixing portion, oriented in opposing directions and arranged in spaced parallel planes, the proximal and distal portions connecting to an intermediate portion having a square general profile and having two perpendicular bearing surfaces, the proximal anchoring portion extending from one of the surfaces and perpendicular thereto, whereas the distal fixing portion extends in the extension of the other bearing surface.
