Hard-tissue implants are provided that include a bulk implant, a face, pillars, slots, and at least one support member. The pillars are for contacting a hard tissue. The slots are to be occupied by the hard tissue. The at least one support member is for contacting the hard tissue. The hard-tissue implant has a Young's modulus of elasticity of at least 3 GPa, and has a ratio of the sum of (i) the volumes of the slots to (ii) the sum of the volumes of the pillars and the volumes of the slots of 0.40:1 to 0.90:1. Methods of making and using hard-tissue implants are also provided.

Spinal interbody cages are provided that include a bulk interbody cage, a top face, a bottom face, pillars, and slots. The pillars are for contacting vertebral bodies. The slots are to be occupied by bone of the vertebral bodies and/or by bone of a bone graft. The spinal interbody cage has a Young's modulus of elasticity of at least 3 GPa, and has a ratio of the sum of (i) the volumes of the slots to (ii) the sum of the volumes of the pillars and the volumes of the slots of 0.40:1 to 0.90:1.

Spinal interbody cages are provided that include a bulk interbody cage, a top face, a bottom face, a top mesh structure, a bottom mesh structure, pillars, and slots. The top and bottom faces are exterior surfaces of the bulk interbody cage having a top central opening and a bottom central opening, respectively. The top and bottom mesh structures extend from the bulk interbody cage across the top central opening and the bottom central opening, respectively. The pillars are for contacting vertebral bodies. The slots are to be occupied by bone of the vertebral bodies and/or by bone of a bone graft. The spinal interbody cage has a Young's modulus of elasticity of at least 3 GPa, and has a ratio of the sum of (i) the volumes of the slots to (ii) the sum of the volumes of the pillars and the volumes of the slots of 0.40:1 to 0.90:1.

An implant for attaching a tendon or ligament to a hard tissue is provided. The implant includes a shaft, a convex first surface, a flat or concave second surface, first pillars for contacting a hard tissue, first slots to be occupied by the hard tissue, second pillars for contacting a tendon or ligament, and second slots to be occupied by the tendon or ligament. The implant has a first surface ratio of the sum of the volumes of the first slots to the sum of the volumes of the first pillars and the volumes of the first slots of 0.40:1 to 0.90:1, and a second surface ratio of the sum of the volumes of the second slots to the sum of the volumes of the second pillars and the volumes of the second slots of 0.60:1 to 0.98:1. The second surface ratio is greater than the first surface ratio.

Implant comprising first and second sets of pillars for attaching a tendon or a ligament to a hard tissue

This invention provides a calcaneal plate implanted using a sinus tarsi approach and comprises an anterior section having two locking screw holes, an s-shaped posterior facet section having a four locking holes and which rounds toward the bone at both the inferior and superior edges and is reinforced at the superior edge, and a blade shaped posterior portion having three linearly aligned locking holes and terminating in a tapered portion. There is also, a drill guide assembly having a drill guide column inserted through a hole in a targeting guide and locking to one of the locking holes in the plate, and cannulated drill guide sleeves that lock into holes in the targeting guide in a spaced relation whereby when the targeting guide is locked into the plate, the targeting guide can be used as a handle and wherein locking screws can be implanted percutaneously.

Contoured calcaneal plate and a percutaneous drill guide for use therewith

The invention comprises an implant having a first end section and a second end section, where the first end has a cancellous thread for implantation in a first section of bone and the second end includes expansion slots and barbs or wings, that that resist movement out of a second section of bone. These anchors expand outwardly when a rigid wire, such as a k-wire is fed through a central cannulation in the implant and either the wire expands in diameter or the cannulation decreases in diameter. The implant also includes a collar intermediate to the first and second section which includes one or more surfaces to allow the first section to be screwed into a first bone section.

An orthopedic plate is designed for opening osteotomies and includes a contoured double tabbed or butterfly shaped plate portion which can accommodate selective fixation including locking, variable locking and non-locking. The plate also includes a centrally located osteotomy support that maintains the opening between bone segments at a spaced relationship. The support can be integral to the plate, or can be modular, i.e. a separate and adjustable segment which can be changed to accommodate the desired geometry of the osteotomy site.
