An implant is provided for use in an ankle joint between reconditioned end surfaces established on a distal end of an upper tibia bone and an opposing lower talus bone. The implant comprises a substantially porous rigid component adapted to be anchored against the upper tibia reconditioned end surface and the lower talus reconditioned end surface. The component defining an opening therethrough. An intramedullary nail is configured to pass through the opening in the component when the nail is driven through the talus and into the tibia.

An apparatus and method for aligning an acetabular cup. The apparatus may include an acetabular cup (150, 10) and/or a protractor (30) and/or a depth gauge tool (90) and may be provided in the form of a surgical kit. Components of the apparatus may allow an angle of rotation of an acetabular cup about an axis (111) of the cup relative to an anatomical feature of a patient to be determined when the acetabular cup implant is placed in the acetabulum of the patient. Components of the apparatus may allow an amount of overhang between a rim (12, 162) of an acetabular cup and an edge of the acetabulum to be determined. The acetabular cup may be an acetabular trial cup (10) or and acetabular cup implant (150). Embodiments of the invention may allow both the angle of rotation about the cup axis and the amount of overhang between the rim and the acetabulum edge to be determined.

The invention provides a method of making a biological disc graft. In one embodiment, the biological disc graft is useful for treating back or neck pain. In one embodiment, the biological disc graft is useful for treating any joint pain. The invention also provides a method of implanting said biological disc graft in a way that is minimally invasive and less dangerous.

An implant includes a component for fixed attachment to a bone. An underpass layer of a porous material is disposed on a first side of the component for fixed attachment. At least one strut is provided on the underpass layer. The at least one strut has a first surface contacting the underpass layer and a second surface opposite the first surface. The at least one strut comprises a non-porous material. An additional layer of the porous material fills a respective volume adjacent the at least one strut. The additional layer extends from a first side of the underpass layer to a predetermined height at or above the second surface of the at least one strut.

Various surgical devices and methods are disclosed herein. Also disclosed is multi-component prosthesis, which can be used as an ankle prosthesis. One of the disclosed surgical alignment systems includes a guide arm, a ratchet arm frame configured to be coupled slidably to the guide arm, a ratchet arm configured to be coupled to the ratchet arm frame, and a sagittal sizing guide body configured to be coupled to the ratchet arm. The sagittal sizing guide body includes a first radiopaque object disposed at a first position and a second radiopaque object disposed at a second position that is spaced apart from the first position.

The present invention relates to a device and system for surgical fixation of small bones, small bone fragments, and osteotomies and more particularly to compression screw having an elongated and spiked tapered threaded leading portion which is joined to a section that is free from threads and a threaded trailing portion and more sharply tapered head which has threads that continue from the threads of the leading portion.

A position adjustment device having a tool holder is locked to at least two pins projecting from respective anterior facing locations near a distal end of a tibia of a patient. The position adjustment device is adjusted. The position adjustment device is locked with the tool holder at first coordinates in the proximal-distal and medial-lateral directions. The distal end of the tibia is resectioned with a tool positioned on the tool holder, while the tool holder is in the first coordinates in the proximal-distal and medial-lateral directions. The tool is removed from the tool holder. A tibia trial is placed on the resectioned tibia using the tool holder, while the tool holder is in the first coordinates in the proximal-distal and medial-lateral directions. The tibia trial has a size and shape of a tibial tray of an ankle replacement system.

A total ankle replacement prosthesis may comprise a tibial implant, a talar implant, and an intermediate implant. The intermediate implant may fixedly attach to the tibial implant and may articulate with respect to the talar implant. The intermediate implant may have unequal front and back angular extent, so as to discourage a particular direction of subluxation, and a kit may be provided containing various such intermediate implants. Various features may be provided in regard to dovetails, fins, recesses, the placement of fins and pegs, and the shape of the perimeter of the tibial implant. Recesses may allow a surgical blade to slice a latch off of an already-installed intermediate implant, in order to allow its removal from the tibial implant.

Resection guides include a body a plurality of alignment pin through-holes and a plurality of guide through-holes so that the pattern of guide through-holes is operable for receiving a drill for use in resecting the at least a portion of the anatomical structure of the patient. Sweeping reamers include a body having a plurality of alignment pin through-holes and an elongated opening, and a reamer extendable through the elongated opening of the body. Decoupled resection guides include a first body having a plurality of alignment pin through-holes and a second body having a plurality of fixation pin through-holes and at least one guide aperture operable for guiding a cutting tool for use in resecting a portion of the second anatomical structure of the patient. Methods employing the same are disclosed and operable in, for example, total ankle replacement.
