A rotary mill is disclosed comprising a body portion (4) having a milling surface (10) and a central bore (20) extending along an axis of rotation (18) of the body portion (4); and a guide portion (6) having a guide body (22) and a guide peg (24) extending from the guide body (22), the guide peg (24) operable to be received in the central bore (20) of the body portion (4), the guide body (22) having at least one alignment feature (28, 30) which is the same as that of a prosthesis component. A method of implanting a unicondylar femoral component is also disclosed, the method comprising, a) reaming the femoral condylar surface to accept the unicondylar femoral component; b) drilling peg holes for affixing the unicondylar femoral component; c) affixing a guide portion of a rotary mill onto the prepared condylar surface using the drilled peg holes; d) reaming a portion of bone anterior to the affixed guide portion; e) removing the guide portion from the bone; and f) affixing a unicondylar femoral component to the prepared condylar surface.

A tool for scrubbing, removing tissue from the medullary cavity or joint cavity of a bone or removing cartilage and/or cortical bone from a joint cavity has a proximal end, a distal end, and a cannula extending therethrough. The distal end includes at least one scraping surface and/or cutting surface to soften marrow in the medullary cavity or joint cavity as the scraping and/or cutting surface(s) are rotated or otherwise moved relative to the medullary cavity or joint cavity. When used, the tool may be attached to a drill and the cannula receives a K-wire previously inserted into the medullary or joint cavity. The drill rotates the tool around the K-wire and pushes the tool over the K-wire into the medullary cavity or joint cavity.

This disclosure relates to reaming assemblies and methods for repairing bone defects. The reaming assemblies disclosed herein may be utilized for removing bone prior to positioning a graft and/or implant at a surgical site.

The disclosure provides a fixation device for internal fixation of an osteotomy below the tibial tuberosity. The fixation plate including a top-end portion including three pinholes, three screw holes, and a first Combi hole; a bottom-end portion including a second Combi hole, two screw holes, and one pinhole; and a connection portion connecting the top-end portion to the bottom-end portion. The top-end portion is capable of fixating the portion of the tibia above a cut of the osteotomy, and the bottom-end portion is capable of fixating the portion of the tibia below the cut.

A flip cutter and drill instrument and method of antegrade drilling and retrograde cutting using such an instrument. The flip cutter and drill instrument is provided with a drill which has a multi-blade configuration and which engages an inner tube or inner member of the instrument to articulate between at least a first “straight” position (for example, about parallel to the longitudinal axis of the instrument) when the instrument is in the drilling mode, and at least a second “flip” position (for example, a non-parallel position relative to the longitudinal axis of the instrument) when the instrument is in the cutting mode.

Methods and devices for consistently and accurately controlling the depth of the graft tunnel. A sheath is inserted into the bone until a stop member on the sheath contacts the bone. A cutting member is then deployed to drill a larger bore in the tunnel until making contact with the distal end of the sheath. The cutting member may be drawn retrograde within the tunnel, or driven antegrade from an opening opposite the opening in which the sheath resides. The drill and the sheath can then be removed, leaving the tunnel that includes a tunnel portion sized to fit a graft so that the graft fits tightly within the tunnel portion and is flush with the opening of the tunnel.

A tibial plateau leveling osteotomy (TPLO) system is provided for surgical correction of a stifle joint of an animal. The system includes a bone plate, fixed angle locking screw, compression screw, and a K-wire. The bone plate includes first surface and a second surfaces having common structure such that each can be positioned against the bone. The plate has a first shaft portion with a dynamic compression screw hole having a major length both extending along a first axis, and second shaft portion with a second axis and K-wire slot defining a major axis angled relative to the second axis but parallel to the first axis. The locking screw has double lead threads and the threaded holes in the plate have quad-lead threads.

A reamer device is used in the preparation of the fibula prior to the placement of an intramedullary nail. The reamer device features one or more indicating grooves on its cutting edges. These grooves can be visualized radiographically during reaming to confirm depth for the placement of syndesmotic implants through the intramedullary nail.

An osteotomy surgical apparatus according to the present invention includes a bone cutting blade used for cutting bone tissue and a guard disposed so as to overlap the bone cutting blade in a side view of the bone cutting blade. A distal end of the guard is disposed at a position retracted rearward relative to a blade edge of the bone cutting blade.

A system includes a first spacer sized and configured to be received within a resected bone space of a first bone and a second spacer sized and configured to be coupled to a second bone. The first spacer and the second spacer each include a body extending between a bone contacting surface and a coupling surface. At least one shim is positioned between the first and second spacers. The shim includes a body extending between a first coupling surface and a second coupling surface. The first spacer, the second spacer, and the at least one shim position the first and second bones in a predetermined alignment. An adjustable guide including a guide adapter and a guide body is configured to couple to the first spacer and is adjustable on a first axis.
