A method of preparing a tarsometatarsal joint can include imaging a tarsometatarsal joint of a patient between a metatarsal and a cuneiform to determine a size and/or angle of a wedge-shaped bone portion to be cut at the tarsometatarsal joint. The method can include obtaining a bone preparation guide that includes a first guide surface positionable over the metatarsal and a second guide surface positionable over the cuneiform, where an angle of the first guide surface relative to the second guide surface is selected corresponding to the size and/or angle of the wedge-shaped bone portion to be cut as determined via imaging of the tarsometatarsal joint. The method can include positioning the guide surfaces over the metatarsal and cuneiform and guiding a tissue removing instrument with the guide surfaces to cut an end of the metatarsal and to cut an end of the cuneiform.

Disclosed herein is a toe implant for replacing a portion of a human toe joint, as well as a related kit, surgical method, and method of manufacturing. Specifically, the toe implant may include a bearing member having a curved interface surface and a fixation member coupled to the bearing member. The fixation member may include a first portion having a non-porous barrier, and a tapered second portion.

A system for providing fixation of first and second bones includes a drill guide that receives a drill bit to create first and second holes in the first and second bones, respectively. Guide pins can be driven into the first and second holes. The guide pins are received by a surgical saw to guide the surgical saw toward a joint between the first and second bones, thereby creating a third hole in each of the bones across the joint. The guide pins are then removed, and an implant can be inserted into the bones, such that a first leg of the implant is disposed in the first hole, a second leg of the implant is disposed in the second hole, and a keel of the implant is disposed in the third hole.

This disclosure relates to surgical planning systems, instrumentation and methods for repairing bone defects. The planning systems and instrumentation disclosed herein may be utilized to establish trajectories of surgical devices and may be utilized to establish resection surfaces for fusion of adjacent bone surfaces.

Apparatus and methods are disclosed for correcting deformities in a patient's foot. In one example, a metatarsus adductus is addressed using a pin placement guide that is angulated to be placed in alignment with a cuneiform and a metatarsal, such that the TMT joint can be subsequently cut, and the metatarsal moved into proper alignment. Th pin placement guide can be a variable angle guide, or a kit of fixed-angle pin placement guides can be provided.

A compressor-distractor device may be used during a surgical procedure, such as a surgical procedure to correct a bunion deformity. In some examples, the compressor-distractor includes first and second engagement arms having first and second pin-receiving holes, respectively. The first and second pin-receiving holes may be angled relative to each other. The compressor-distractor may also include an actuator operatively coupled to the first and second engagement arms. In some example uses, a clinician may pin a first surgical device to a patient's bones use a pair of parallel pins. After removing the surgical device over the parallel pins, the clinician may thread the parallel pins through the angled first and second pin-receiving holes of the compressor-distractor, causing the bones to move relative to each other. Thereafter, the clinician may actuate the actuator on the compressor-distractor to move the bones towards and/or away from each other.

A patient-specific instrument is disclosed for performing an osteotomy. The patient-specific instrument includes a body that includes a proximal side, a distal side, a medial side, a lateral side, and an inferior side having a bone engagement surface shaped to match at least one of a first surface of a first bone, a second surface of a second bone, a third surface of a third bone, and a fourth surface of a fourth bone of adjacent joints. The instrument also includes a superior side having one or more guide features that are positioned to guide resection of at least one of the first bone, the second bone, the third bone, and the fourth bone. The body is configured to seat transverse to the adjacent joints with the bone engagement surface engaging at least one of the first surface, the second surface, the third surface, and the fourth surface.

Systems and methods for performing an osteotomy are presented. Examples include forming a fusion osteotomy at a metatarsocuneiform joint of the first ray of a human foot.

A surgical device includes an body extending from a proximal end to a distal end. The distal end of the body defines a notch sized and configured to receive a reamer. A coupling assembly is supported by the body and includes a reamer guide body disposed at the distal end of the body. The reamer guide body configured to move between a first position and a second position in which the reaming guide body extends at least partially across the notch. A locking assembly is supported by the body and is configured to releasably engage the coupling assembly to maintain the reamer guide body in the second position.

In various embodiments, a surgical instrument, systems including the surgical instrument, and methods of use of the surgical instrument are disclosed. The surgical instrument includes a handle body extending from a proximal end to a distal end substantially along a longitudinal axis. The handle body defines a first channel sized and configured to receive a guide element therein. A plurality of indicators are formed on the handle body. Each of the plurality of indicators correspond to a size of one of a plurality of fixation elements sized and configured for insertion into a bone. A countersink element is coupled to a distal end of the body. The countersink element defines a second channel sized and configured to receive the guide element therethrough that is circumferentially located with and coupled to the first channel. The countersink element includes a head sized and configured to form a countersink in the bone.
