Abstract: A bolt for clamping abutting parts includes a bolt-like part insertable into openings of the abutting parts and including an external thread on a portion of an outer side of the bolt-like part. The bolt-like part includes a bolt component without external thread so that the bolt extends in each of the abutting parts at least partially with the bolt component without external thread. A threaded sleeve projects radially outwardly beyond the bolt-like part and is positionally adjustable by engaging an internal thread of the threaded sleeve in the external thread of the bolt-like part. A clamping element is provided inside the bolt-like part at an end of the bolt-like part in opposition to the threaded sleeve and is movable beyond an outer circumference of the bolt-like part through a bore of the bolt-like part. An actuator acts on the clamping element in order to clamp the abutting parts.

Abstract: A bunion correction device is disclosed which secures a plate to a metatarsal head before an osteotomy is performed to allow for control of the metatarsal head during the bunion correction procedure. The device comprises a body component having two opposing portions positioned orthogonally to one another with a plurality of screw apertures positioned on both portions of the implant. Bone screws or fasteners are driven laterally through the apertures of the first portion into the metatarsal head, securing the first portion or base to the metatarsal head. An osteotomy is performed just proximal to the plate and the metatarsal head is translated to correct the bunion. Bone screws are then placed in the second portion apertures to fix the correction and provide compression of the osteotomy.

Abstract: A graft-harvesting instrument and MTP fusion device are disclosed to allow for easy and safe removal of a section of the calcaneus to be used as autograft in the fusion of the MTP joint.

The MTP fusion device allows for the exact placement of the autograft into the MTP joint. The graft-harvesting instrument allows for a very consistent piece of autograft to be harvested. The graft-retaining sleeve component of the MTP fusion device positions that autograft in place for optimum fusion of the MTP joint.

Abstract: A modular head compression screw system is disclosed and has a cannulated compression screw component with a modular head. The compression screw component includes a tubular body and penetrating tip having a first and second end, and an exterior thread on the tubular body which extends to the second end of the tubular body or penetrating tip. A second exterior thread is positioned around the diameter of the first end to create a posted compression screw. Further, a modular head is removably secured at the first end via the second exterior thread and configured to engage with a driver to advance the compression screw in to the bone. Each modular head component may have a threaded head component which removably secures to the first end of the tubular body, and a fixation component which acts to engage tendons and/or bones.

Abstract: A multiple drive interference screw device with a head having multiple insertion features. The screw component has a tubular body with a first end and a closed second end, and the head is positioned at the first end and configured to engage with a driver to advance the screw into the bone A penetrating tip is positioned at the second end. The head of the screw component has at least three insertion features, such as a hex shaped insertion feature around the major diameter of the head and a hexalobe shaped insertion feature within the hex shaped insertion feature, and a sprocket shaped insertion feature positioned exterior to the hex shaped insertion feature.

Abstract: An MTP joint fusion device is disclosed which stabilizes the fusion site without the use of a fusion plate. Further, the MTP joint fusion device comprises an MTP head replacement component placed over the distal end of the first metatarsal. This portion of the device contains the bone ingrowth matrix. An intramedullary screw is driven through the distal central portion of the device into the base of the proximal phalanx of the hallux. At least two metatarsal screws are driven radially through the device into the metatarsal neck area. This secures the MTP head replacement component to the metatarsal at a specifically determined angle. Thus, the MTP joint fusion device provides for a more secure fusion environment, increased capacity for bone ingrowth, less potential for irritation from retained hardware, and earlier weight bearing as compared to traditional methods.

Abstract: A stand-alone ALIF implant that comprises a cage and a rotatable plate attached to an anterior portion of the cage by a fastener mechanism. The plate may also be integrally formed with the cage, and both are typically manufactured using additive manufacturing techniques. Support material may be added during the additive manufacturing process to lend support to the implant, and may be positioned around the fastener mechanism during manufacturing of the implant. Once formed, the support material may be dissolved away, thereby allowing the plate to rotate independently from the cage, but still remain movably attached via the fastener mechanism. The cage may further comprise webbing thereon to promote bone growth.

Abstract: A posterior lumbar interbody fusion (PLIF) implant that comprises a body with substantially parallel posterior and anterior sidewalls, and a pair of superior and inferior faces. The implant is inserted via an insertion tool within a depression in the sidewalls of the implant. The insertion tool is secured to the side walls of the implant to prevent any bending or breaking of the implant or the inserter during implantation. Once inserted, the implant may be rotated approximately 90 degrees within the disc space. Because of the shape and size of the implant, the effective height of the implant within a patient's disc space is increased upon rotation.

Abstract: A structurally encoded implant comprising a pair of endplates movably secured at the posterior end via a slip joint and a wedge component. The wedge component is inserted between the pair of endplates to increase implant height and change the lordotic angle. The pair of endplates may be manufactured together as one integral component using additive manufacturing techniques. During this additive manufacturing process, water-soluble support material may be positioned around the slip joint. Once the pair of endplates is formed, the support material may be dissolved away, allowing the pair of endplates to move independently from one another, but to still remain movably attached via the slip joint, such that the pair of endplates allow for height expansion and lordotic angle change.
