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.

A method of ankle replacement includes forming an anterior cut in a bone and forming a stem hole in a distal end of the bone. The stem hole is formed using a plurality of broaches positioned against the distal end of the bone through the anterior cut. A first portion and a second portion of a stem implant are inserted into the stem hole through the anterior cut in the bone. The first portion is coupled to the second portion using a coupling device inserted through the anterior cut in the bone. The stem implant is impacted into the stem hole using an offset impactor.

Devices and techniques for adjusting an alignment for a first metatarsal may include making a plurality of cuts along the length of the first metatarsal. In different applications of the technique, a plurality of transverse cuts may or may not be made intersecting the longitudinal cuts. In either case, the cuts can separate the first metatarsal into two individual portions and release a removable wedge of bone. The different portions of the metatarsal can be moved relative to each other to adjust an anatomical alignment of one portion relative to another portion, for example in multiple planes. After suitably adjusting the alignment of the different bone portions, the portions can be fixed together.

A guidance system comprises a first guide configured to be detachably mounted to a first portion of a bone. The first guide has a first axis for alignment with a longitudinal axis of the first portion of the bone. A second guide is mountable on the first guide. The second guide is slidably translatable in a transverse direction relative to the first axis. A third guide is mountable on the second guide. The third guide is selectively positionable along a curved path extending at least part way around the longitudinal axis.

A technique for correcting a bone deformity, such as a bunion, may be performed using a fulcrum. In some examples, the technique involves inserting a fulcrum between a first metatarsal that is anatomically misaligned with respect to a second metatarsal. The technique further includes preparing an end of the first metatarsal and preparing an end of a medial cuneiform opposing the end of the first metatarsal. In addition, a distal portion of the first metatarsal is moved toward the second metatarsal in a transverse plane, thereby pivoting a proximal portion of the first metatarsal about the fulcrum and reducing an intermetatarsal angle between the first metatarsal and the second metatarsal.

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.

An oscillating decorticating burr assembly for decortication of the articular surfaces of joints of the human body is disclosed. The oscillating decorticating burr assembly comprises a burr, a burr-support post, and a handle. Power is imparted to the assembly by way of a user input on the handle causing oscillation of the burr.

A resection guide includes a first body portion and a second body portion. The first body portion has a first bone engagement structure and defines a first plurality of holes. The second body portion has a second bone engagement structure and defines a second plurality of holes. The first body portion and the second body portion are operable to separate a first anatomical structure of a patient and a second anatomical structure of the patient. A cutting guide defines at least one guide aperture that is operable for guiding a cutting tool for use in resecting a portion of the second anatomical structure of the patient. The cutting guide is positionable relative to the first body portion.

The present application relates to repair systems, and more particularly to fifth metatarsal repair systems and methods of use. The repair systems described herein can include a fixation device with a threaded section. The repair systems described herein can include one or more grippers designed to be deflected outward to grip the sidewalls of an intramedullary canal of the fifth metatarsal. The repair systems described herein can include an end cap. The end cap can include a fastener including thread designed to engage the threaded section of the fixation device. The end cap can include a cap designed to move relative to the fastener.

An orthopaedic surgical instrument, in particular a milling cutter, including: an inner rod extended along an own longitudinal axis and provided with an attachment end to a motorized member; a tubular envelope wrapping the inner rod; an operating head at a rod end which is opposite said attachment end; a gimbal joint between the rod end and a tool of said operating head such that said tool is extended along an angled axis with respect to the longitudinal axis. The milling cutter according to the invention improves the precision of execution of the positions of the holes in any surgical operation with anatomy which is difficult to get access to, such as in knee, pelvis and ankle.
