Abstract: An apparatus for locating a curvilinear cut in a bone comprises a jig body and a first arm, a top end of which is rotatably coupleable to a first portion of the jig body in combination with a second arm, a top end of which is rotatably coupleable to a second portion of the jig body separated from the first portion and a saw guide rotatably coupleable to the first arm, the saw guide including a bottom surface extending along a curve corresponding to a desired path through which a bone is to be cut, the saw guide including a locking feature receiving a bone fixation element which, in an operative configuration, is mounted in the bone to align the saw guide relative to the arm so that an operator may precisely align a desired axis of the saw guide with a longitudinal axis of the first arm.

Abstract: An improved tibial plateau leveling osteotomy plate is disclosed. The plate is contoured in its proximal head portion to more closely resemble the structure of the tibial bone segment that is cut and rotated during the procedure. The plate also preferably has screw holes in the proximal head portion that are machined through the pre-contoured proximal head portion and are designed to angle the screw in a targeted screw path with respect to the osteotomy.

Abstract: A bone plate is configured for pancarpal arthrodesis. The bone plate can include a plurality of apertures that can be aligned with the metacarpal bones. The apertures can include a first portion and second portion that is longitudinally and laterally offset with respect to the first portion.

Abstract: Various methods and apparatus for cranially advancing the tuberosity and patellar tendon of a quadruped are disclosed. The patellar tendon can be advanced directly or indirectly by performing an osteotomy on the tuberosity, and subsequently advancing the tuberosity cranially to an advanced position. Implants are further disclosed for maintaining the patellar tendon, and in some embodiments also the tuberosity, in the advanced position.

Abstract: An external fixation system for connecting one or more bone segments together to facilitate healing of bone. The system may include one or more rings and/or ring segments. One or more linear distractors and/or angular distractors may connect the rings to each other so as to allow for distraction and/or reduction/compression of a bone. Linear distractors may enable an operator to move the rings towards and away from each other, while angular distractors may enable an operator to angle the rings relative to each other. In an embodiment using angular distractors, one or more angular separation assemblies may be positioned between the rings. These separation assemblies may have joints which may two portions which may be angled relative to each other and connected directly or indirectly to the rings. Various fasteners (e.g., nuts) and/or tightening members may configured for quick movement along and selective tightening to various components.
