A device comprises a base. A support is attached to the base. The support is shaped to receive a calf of a person and adapted to receive a wire or pin for securing a tibia of a person. A foot plate is attachable to the base. The foot plate has a plurality of attached members. The members are configured for receiving at least a first wire or pin to fix a foot of the person relative to the foot plate while the foot plate is oriented normal to a superior-inferior direction of the foot. The foot plate is rotatable relative to the base while the foot plate is attached to the base.

System for connecting a connection device to a bone with a bone pin, wherein the connection device is provided with an opening for receiving the bone pin, wherein the system comprises: said connection device; a guiding tube arranged to guide the bone pin from the connection device to the bone for connecting the bone pin to the bone, wherein the inner diameter of the guiding tube corresponds to the outer diameter of the bone pin and wherein the guiding tube can be slidably received in the opening, the guiding tube being slidable with respect to the connection device along an axis parallel to a longitudinal axis of the opening; a locking device arranged to be received in the opening of the connection device and arranged to engage the bone pin for locking the bone pin with respect to the connection device, wherein the guiding tube is movable with respect to the connection device and bone pin such that the guiding tube is removable from the combination of the bone pin and the connection device and wherein the locking device is arranged to lock the bone pin after removal of the guiding tube.

A device includes a plurality of rings. Each ring has a first face, a second face, and at least one slot defined by first and second interior edges of the ring on opposing sides of the slot. The at least one slot penetrates from the first face to the second face. The first face of each ring has a first recess adjacent the slot on the first edge and a second recess adjacent the slot on the second edge. A plurality of posts join each one of the plurality of rings to an adjacent one of the plurality of rings.

A system for performing a total joint arthroplasty procedure on a patient's damaged bone region. A CT image or other suitable image is formed of the damaged bone surfaces, and location coordinate values (x.sub.n,y.sub.n,z.sub.n) are determined for a selected sequence of bone surface locations using the CT image data. A mathematical model z=f(x,y) of a surface that accurately matches the bone surface coordinates at the selected bone slice locations, or matches surface normal vector components at selected bone surface locations, is determined. The model provides a production file from which a cutting jig and an implant device (optional), each patient-specific and having controllable alignment, are fabricated for the damaged bone by automated processing.

A percutaneous metatarsal fixation guide, including methods of use, is provided. The percutaneous metatarsal fixation guide includes a means for aligning a drill guide bearing a drill sleeve with the central longitudinal axis of a fractured metatarsal, metacarpal, or similar bone. Precise radiographic alignment of the drill sleeve with the long axis of the fractured bone facilitates accurate placement of fixation hardware across the fracture site, allowing for healing in alignment. The fixation bearing two corresponding index wheels is rigidly mounted to a tarsal bone via a temporary threaded K-wire, wherein an index marking on a second index wheel coupled to a drill sleeve may be positioned to correspond with an index marking on first index wheel coupled to an alignment guide, such that the drill sleeve is aligned with the fractured metatarsal. This allows precise placement of fixation hardware, compared to using a conventional free-hand technique.

A system includes a cutting guide having a base body configured to be fixed to a first bone of a patient and a cutting slot block configured to provide a guide for cutting at least one of the first bone and a second bone of the patient. The cutting slot block is rotationally coupled to the base body. The cutting slot block is configured to rotate in a first rotational direction. The cutting guide comprises a distal portion and a proximal portion.
