An anchoring system for the implantation of at least one anchoring device in at least one preferably bone tissue, the system is disclosed, with some embodiments comprising: at least one anchoring device comprising a curved body extending between an anterior end intended to penetrate without any deformation in the bone tissue and a posterior end intended to remain turned outward of the bone tissue, at least one guide extending along a longitudinal axis between a posterior end and an anterior end and comprising at least one guiding surface, substantially along the longitudinal axis, able to guide at least one anchoring device.

A surgical apparatus generates energy that is input onto an appliance. The appliance is one of an implant to be implanted in human or animal bone tissue by the input of the energy, and of a tool being an ultrasonic bone cutting and/or punching tool for cutting and/or punching living human or animal bone tissue by input of energy onto the implant in a surgical operation. The apparatus includes a control device and at least one handpiece, the handpiece being equipped to be held by a surgeon during the operation and to couple the energy into the appliance. The apparatus further includes a reading device equipped to read out, from an appliance data carrier, appliance data dedicated to the appliance. The control device checks, depending on the appliance data, whether the handpiece is suitable for the appliance and chooses operating parameters depending on the appliance data.

The present disclosure provides for improved bone implantation and stabilization assemblies, and improved systems/methods for deploying and/or undeploying such bone implantation and stabilization assemblies. More particularly, the present disclosure provides for improved devices, systems and methods for stabilizing bones and/or bone segments. In exemplary embodiments, the present disclosure provides for improved devices, systems and methods for deploying bone implantation and stabilization assemblies into bone tissue (e g., spinal structure, vertebrae, cancellous bone, cortical bone, etc.) in order to stabilize bones and/or bone segments.

A compression screw for applying compression at a bone joint. The compression screw includes an axial screw body extending from a distal end to a proximal end with the distal end including a series of bone engaging threads configured to be self-drilling and self-tapping and the proximal end including a head which defines a radially extending shoulder. At least one proximal rotary cutting structure is defined proximally of the bone engaging threads. The at least one proximal rotary cutting structure is configured to be self-drilling such that a proximal portion of the axial screw body cuts into and advances within a bone of the bone joint as the axial screw body is advanced. A method of inserting the compression screw is also provided.

The invention relates to an orthopedic locking screw, an orthopedic locking system, and a method for manufacturing an orthopedic locking screw. The orthopedic locking screw may be used for locking an intramedullary nail. The orthopedic locking screw comprises a screw shaft. The screw shaft comprises a recess. The recess extends at least partially along a longitudinal axis of the screw shaft. The recess extends at least partially along a chord of a cross section of the screw shaft. A surface of a circular segment comprising the chord is at least partially provided with a threaded portion.

Apparatus and methods for bone fracture repair. The apparatus may include a structural support for positioning a first bone segment relative to a second bone segment. The apparatus may include an anchoring substrate. The anchoring substrate may be configured to compress the first bone segment to the second bone segment. The anchoring substrate may transmit tension from a distal bone segment anchor in the first bone segment to a proximal bone segment anchor in the second bone segment. The apparatus may be configured to be deployed percutaneously in an inner cavity of a bone. The apparatus may be installed in an open fracture. The apparatus may be expanded, self-expanding or configured for mechanically actuation. Some embodiments of the apparatus may include a central axis member that may be used in conjunction with expansion of one or both of the structural support and the anchoring substrate to configure the apparatus.

A dual-start fastener is disclosed having two threads helically wound about its shaft. The thread tooth profile (in section) constitutes substantially parallel upper and lower facets on each thread flank. A first thread has a crest diameter greater than a second thread. A distal end of the fastener includes self-tapping cutters formed on the threads which force shards of bone to advance into shallow troughs adjacent the cutters for subsequent resorption by adjacent osseous tissue.

The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region is generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.

A fusion device includes a screw having a head and a shaft. A hollow bone dowel is disposed about the shaft of the screw. The bone dowel is formed from a bone-like, biocompatible, or allograft material.

A spinal interbody cage implant includes a cage, an endplate, and flexible barbs. The endplate is separately attached to the cage and is configured to receive, hold and direct a flexible barb into an upper vertebral surface and a flexible barb into a lower adjacent vertebral surface. Each proximal leg of the cage is configured to receive the endplate, and has a lateral bore that receives a pin which retains the endplate. The endplate directs a first flexible barb upwardly toward an upper vertebral surface, and directs a second flexible barb downwardly toward a lower vertebral surface. Each flexible barb has a proximal head, a shaft extending from the head with a bore extending from the head to its distal end. Teeth are provided along the exterior surface of the shaft with two flats disposed on opposite sides thereof with a slit extending from the distal end towards the head.
