A wedge osteotomy method inserts a first wire into a first bone of the foot, distal from tissue to be removed. A second wire is inserted into a second bone, so the tissue to be removed is distal from the second wire. A cut guide is pivoted about the first wire, until a first axis of the cut guide is parallel with a longitudinal axis of the first metatarsal. The cut guide has a slot perpendicular to the first axis for guiding a cutter to cut bone, while the first axis is aligned with the longitudinal axis of the first metatarsal. The cut guide is then pivoted about the second wire, until the first axis is aligned with the longitudinal axis of the talus, and bone is cut through the slot, to form a second planar cut into or through bone material.

The invention relates to a surgical guide for receiving and guiding a surgical instrument performing a bone osteotomy, the guide including a body, at least one cutting channel extending in length along the first body face and extending through the body, the cutting channel having a discrete length such that the channel is bounded by the first and second body faces through which it extends, two or more apertures adapted to receive a fixation device, the guide including one or more elongate arms or arm assemblies directly or indirectly connected to and extending from one side wall of the body. The guide may be used in canine tibial plateau levelling osteotomy and other orthopedic or surgical procedures. Also described are methods for use of the guide.

A bone positioning guide may include a main body member, a shaft, and a bone engagement member. The shaft can be movably connected to the main body member and have the bone engagement member rotatably coupled to its distal end. The bone engagement member can have a surface configured to engage a bone. The main body member can also include a tip opposite the bone engagement member for engaging a second bone. In use, the bone engagement member may be positioned in contact with a medial side of a first metatarsal while the tip is positioned in contact with a lateral side of a different metatarsal, such as a second metatarsal. The shaft can then be moved to advance the bone engagement member toward the tip, causing realignment of the first metatarsal.

A surgical guide includes a first guide arm extending from a first end to a second end on a first longitudinal axis. The first guide arm defines a first plurality of openings sized and configured to receive a first guide element therethrough. A second guide arm extends from a first end to a second end on a second longitudinal axis. The second guide arm defines a second plurality of openings sized and configured to receive a second guide element therethrough. A pivot element couples the first end of the first guide arm to the first end of the second guide arm such that an angular distance between the first guide arm and the second guide arm can be adjusted in a first plane.

A guide for placing a landmark(s) in a patient tissue comprises a central portion defining at least one guiding bore configured to receive and guide a tool for placing the at least one landmark in the patient tissue. Extended portions project away from the central portion, each of the extended portions having respective lower base surfaces contoured to mate with the patient tissue, at least the respective lower base surfaces being customized as a function of preoperative imaging of the patient tissue, whereby the guide is specific to the patient.

Methods for temporarily fixing an orientation of a bone or bones. Methods of correcting a bunion deformity. Bone positioning devices. Methods of using a bone positioning device. Bone preparation guides. Methods of using a bone preparation guide.

A patient tissue includes a primary patient tissue area and an anatomically differentiated bordering secondary patient tissue area. An apparatus is at least partially customized responsive to preoperative imaging of the patient tissue. Means are provided for mating with the primary patient tissue area in a preselected relative orientation. Means are provided for fixing a first landmark to the primary patient tissue area in at least one of a predetermined marking location and a predetermined marking trajectory. Means are provided for fixing a second landmark to the secondary patient tissue area in at least one of a predetermined marking location and a predetermined marking trajectory. A method of associating a plurality of landmarks with a patient tissue is also provided.

The invention relates to a fibula bone-material removal and transfer template (1) having a main part (4) designed for application to a bone region (3), wherein at least one bone separation-tool guide portion (8) can be or is removably attached to the main part (4), and wherein a receiving pocket (10a, 10b, 11a, 11b) designed to receive an implant (9) is formed in the main part (4). The invention also relates to an assembly kit comprising the fibula bone-material removal and transfer template (1) and an implant (9).

The disclosure relates to an implant system for promoting an osteosynthetic process at a gap between two bone fragments at a bone of an endoskeleton, in particular of a human mammal. In order to have available an implant system of this kind which allows patient-specific bone reconstruction of a bone, in particular an ulna and radius, wherein the gap between the two bone fragments created during the correction can be supplied with a patient-specific, accurately fitting artificial graft, a graft is provided, which can be inserted into the gap between the two bone fragments; an osteosynthesis plate is provided, which can be fastened to the bone and to the graft ; and a connection device is provided for connecting the graft and the osteosynthesis plate.

A fixation plate for securing together adjacent first and second bone sections of a bone with a bone cut extending thereinbetween, the fixation plate comprising: a first fixation portion having a bone interface side superposable against the first bone section and a second fixation portion extending away from the first fixation portion, the second fixation portion including a holding portion shaped to conform to an outer surface of the second bone section when superposed thereto and when the first and second bone sections are at a predetermined angular orientation relative to each other such that a snug fit of the second bone section with the holding portion provides an indication that the first and second bone sections are at the predetermined angular orientation relative to each other.
