Abstract: A method and apparatus for remote alignment of a cut guide. The cut guide may be positioned on a base which is remote from a surgical site and positioned on a docking station. An alignment jig is removably positioned on a bone and is used to provide alignment information to the docking station. The docking station remotely aligns the cut guide relative to the base. Thereafter, the cut guide and base are removed from the docking station and positioned on the bone in place of the alignment jig. A surgical procedure using the cut guide may then be completed.

The orthopaedic implant comprises an open porous metal component, having pores for promoting bone regeneration, and a resorbable bone growth promoting component which is resorbed into new bone. The orthopaedic implant and methods of the present disclosure provide structural support for the bone as well as osteoconductive and/or osteoinductive matrix for promoting bone re-growth within bone void. Advantageously, the orthopaedic implants and methods disclosed herein are useful in filling critically sized bone voids.

Abstract: An orthopaedic implant for filling a bone void and a method of using the same. The orthopaedic implant comprises an open porous metal portion and a bone cement portion. At a first surface region, the open porous metal portion facilitates bone and/or soft tissue ingrowth into the pores of the first surface region of the open porous metal. At a second surface region, the open porous metal facilitates reception of the bone cement into the pores of the second surface region of the open porous metal. The open porous metal portion of the orthopaedic implant may also be formed of a plurality of porous metal fragments aggregated together with the cement portion of the orthopaedic implant. Additionally, the orthopaedic implant may be pliable and thereby capable of being molded to the shape of a void in a bone.

An implant comprises cartilage or chondrocytes and a subchondral base comprising trabecular metal. An implant can comprise a geometric shape such as a cylinder or an anatomical shape such as a condyle, and can be used in conjunction with a positioning structure.

Abstract: A stop is used for limiting the drill depth of an osteotomy drill bit within a bore in bone. This stop may have a generally tubular body for being releasably mounted on the drill bit and have a cam slot disposed at the body and used for defining a plurality of axial positions. The cam slot is configured for releasably securing a cam follower associated with a drill assembly that extends radially relative to a longitudinal axis of the drill bit assembly to axially secure the stop to the drill bit assembly. Additionally, the stop includes an apical end section that is configured to engage bone adjacent to the bore and limit the apical motion of the drill bit.

Abstract: A hip spacer mold forming a spacer with a spacer stem connected to a spacer head has a stem portion for forming a spacer stem. The hip spacer mold also has a plurality of interchangeable head modules configured for alternatively forming spacer heads of a plurality of different predetermined sizes. The head modules are configured to be disposed adjacent the stem portion.

Abstract: Embodiments of the present invention provide a spinal implant system and method. One embodiment of the present invention includes a spinal implant comprising, a first implant plate, a second implant plate, a spacer member coupled between the first implant plate and the second implant plate and an end plate coupled to the spacer member, the end plate configured to couple to adjacent vertebrae. The implant plates can include spacer channels that receive the spacer member and insertion tool channels that receive an insertion tool. Preferably, on each implant plate, the spacer channel is near the center of the plate and the insertion tool channels are on either side of the spacer channel. The spacer channels and insertion tool channels can be dovetailed or otherwise shaped to capture a portion of the spacer member and insertion tool. Mating connectors can prevent removal of the spacer member from the spacer channels.

Abstract: A joint alignment method comprises using imaging data of at least a portion of a leg to create a leg model, wherein the leg model includes a femur having medial and lateral condyles and a tibia having tibial plateaus that are configured to engage the medial and lateral condyles at a knee joint, displaying an image of the leg model for manipulation by a user, locating a pivot point within one of the medial or lateral condyles, and rotating, in the displayed image, the tibia with respect to the femur, about the pivot point, to obtain a desired knee joint articulation in a specified plane.

Abstract: A composite interbody vertebral implant for facilitating fusion of adjacent vertebrae. The implant includes a first endplate of a porous metal material and a second endplate of a porous metal material which are configured to allow bone in-growth. The implant also includes a polymeric body positioned between and bonded to the first and second endplates such that polymeric material of the polymeric body is impregnated into pores of the first and second endplates to bond the components together. The implant may include a cavity extending through the composite implant configured to receive bone growth material to facilitate fusion between a first vertebra and a second vertebra.

Abstract: The present invention generally provides implantable articles and methods of forming implantable articles from a crosslinked ultrahigh molecular weight polyethylene (“UHMWPE”) blend stabilized with Vitamin E. The crosslinked UHMWPE blend may be prepared by combining the UHMWPE material and vitamin E prior to irradiating the UHMWPE blend with electron beam radiation at a sufficient radiation dose rate to induce crosslinking. The crosslinked UHMWPE blend may be incorporated into a variety of implants, and in particular, into endoprosthetic joint replacements.

Abstract: Tools or other instruments can be used by a surgeon to complete an orthopedic procedure. One tool can include a resection tower and a valgus guide. The resection tower can include a cutting block and a dial coupled with the cutting block. The resection tower can be configured such that rotational movement of the dial, about an axis, effectuates movement of the cutting block along a plane substantially parallel with the axis. The dial, when rotated in a first direction, can move between a first position, which corresponds to a minimum cutting depth of the cutting block, and a second position, which corresponds to a maximum cutting depth of the cutting block. The valgus guide can be coupled with the resection tower and includes a rotatable member. The rotatable member can include an angular surface with one or more variable depth splines providing varus/valgus angle adjustment of the cutting block.

Abstract: A system for installing a vertebral stabilization system. The system includes an installation tool including a handle portion and a shaft extending distally from the handle portion. The shaft includes a conduit and a staple mechanism. The system also includes a flexible implant member extending along the conduit configured to be advanced out from a distal end of the shaft, and a staple housed in the staple mechanism. The staple is configured to secure the flexible implant member to a vertebra. The handle portion is configured to selectively advance the flexible implant member from the shaft and to selectively actuate the staple mechanism.

Abstract: A surgical tool for tensioning a flexible member of a vertebral device, the flexible member having at least one end portion to which tension is applied. The surgical tool includes a longitudinal member having a longitudinal axis, a first end provided with an element for securing in rotation at least one end portion of the flexible member with the first end of the longitudinal member, and a second end provided with a handling element. The surgical tool also includes a guiding structure comprising a first end adapted to be applied against the body of the vertebral device, and at least one guiding element for guiding in rotation the longitudinal member about the longitudinal axis. The guiding structure maintains the longitudinal axis of the longitudinal member with respect to the body, whereby the rotation of the longitudinal member with the handling element produces the tensioning of the flexible member.
