A build plate includes a surface that defines at least one opening configured for disposal of a proximal portion of a screw shaft. The proximal portion is formed by a first manufacturing method and defines a distal face. The proximal portion is connected with the surface in a configuration to orient the distal face for forming a distal portion of the screw shaft thereon by a second manufacturing method that includes an additive manufacturing apparatus. In some embodiments, systems, spinal constructs, surgical instruments and methods are disclosed.

Disclosed are system and methods that use at least one non-threaded anchor and an implant with at least one aperture to join boney structures, where the interaction of the head of the anchor with the implant aperture causes the anchor to move transversely with respect to an initial trajectory. This movement causes compression or distraction of the boney structures which are coupled to the anchors.

Compression devices for joining tissue and methods for using and fabricating the same.

A surgical fastener for use in posterior surgeries that require fusion between the occiput and pelvis. Among other things, the surgical fastener includes a cutter for cutting bone or other 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 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.

Implant assemblies, systems, and methods for stabilizing a joint between a superior vertebra and an inferior vertebra may include a plate member coupled to an interbody spacer with at least one fastener that extends superiorly or inferiorly from the implant assembly to anchor within a vertebral body and stabilize the joint. Inserters and methods of insertion may also be included to facilitate fixation of various implant assemblies within the intervertebral space of the joint between the superior vertebra and the inferior vertebra.

Bone implants, including methods of use and assembly. The bone implants, which are optionally composite implants, generally include a distal anchoring region and a growth region that is proximal to the distal anchoring region. The distal anchoring region can have one or more distal surface features that adapt the distal anchoring region for anchoring into iliac bone. The growth region can have one or more growth features that adapt the growth region to facilitate at least one of bony on-growth, in-growth, or through-growth. The implants may be positioned along a posterior sacral alar-iliac (“SAI”) trajectory. The implants may be coupled to one or more bone stabilizing constructs, such as rod elements thereof.

The cannulated compression device creates fixation and compression across its tang housing, thus stabilizing and closing a bone fracture during placement. After insertion of the cannulated compression device, tangs are extended outward from the tang housing, locking the tang housing with respect to both rotational and axial movement. A compression nut is then threaded onto the proximal end of the tang housing. The nut has two sets of threads: a first set of threads interfaces with the tang housing, a second set of threads interfaces with the bone. By using different pitches, the amount of linear movement for the first set of threads and second set of threads is different.

An osseous anchoring implant with optimized expansion, having a tubular body and a rod whose external profile of the rod and internal profile of the tubular body are complementary. The implant being expandable between a rest configuration in which an abutment mechanism interlocks the tubular body and the rod thanks to the reversal of their two respective screw pitches, so that they provide in an expanded configuration radially: a proximal bearing point, a distal bearing point, a “central” bearing point located between these two bearing points, formed by the cooperation between the outer diameter of the rod and the inner diameter of the tubular body which induce an outer diameter of the tubular body at the “central” level greater than the outer diameter of the tubular body at the proximal bearing point.
