A tether assembly may be attached to a bone to correct a rotational deformity. The bone may have a growth plate that separates a first section of the bone from a second section of the bone. The tether assembly may have a tether member with a first end, a second end, and a central portion extending between the first end and the second end. The first end may have a closed outer wall that defines and fully bounds a first aperture. The second end may have an open outer wall that defines and partially bounds a second aperture. The open outer wall may define a slot in communication with the second aperture. The first and second ends may be securable to the first and second sections of the bone via coupling members inserted through the first and second apertures and anchored in the first and second sections, respectively.

A metatarsal correction procedure may be performed so as to minimize the length of the surgical incision created during the procedure. A variety of different instruments and/or techniques and facilitate the minimal incision procedure. In some examples, a technique involves making a comparatively small surgical incision to access a tarsometatarsal joint. A metatarsal and a cuneiform separated by the tarsometatarsal joint can be prepared. In addition, the metatarsal can be moved relative to the cuneiform using a bone positioning device having a metatarsal engagement member positioned in contact with the skin of the patient on a medial side of the metatarsal. After moving the metatarsal, a fixation device can be installed across the tarsometatarsal joint to cause fusion. In some examples, a plate holder is attached to a U-shaped bone plate to facilitate plating across the joint through the comparatively small incision.

Surgical instruments and methods for performing an osteotomy are disclosed herein. A surgical instrument includes a body with a distal end, a proximal end, a first surface, and a second surface. The surgical instrument can include cutting burrs positioned on the first surface and/or the second surface. The surgical instrument can include cutting burrs positioned on the first surface and cutting blades positioned on the second surface.

Systems, devices, and methods for performing Lapidus bunionectomy procedures are disclosed. An example method includes inserting a plurality of metatarsal pins into the first metatarsal at a first predetermined spacing relative to the first tarsometatarsal (TMT) joint, excising the first TMT joint by cutting the bases of the first metatarsal and the first cuneiform proximate the first TMT joint, inserting a plurality of cuneiform pins into the first cuneiform at a second predetermined spacing relative to the first TMT joint, compressing the first TMT joint using a compressor block such that a cut face of the first metatarsal contacts a cut face of the first cuneiform, and fixing the first TMT joint using a bone plate and a plurality of bone screws. At least one of the plurality of bone screws may be a cross screw extending at an angle of less than 90 degrees relative to the bone plate and may anchor the resected first TMT joint to the second metatarsal or the second cuneiform to prevent recurrence of the bunion.

Spinal correction surgical techniques and methodologies for correction of scoliosis using non fusion anterior scoliosis correction, including soft tissue releases, unique correction techniques such as de-rotation, and unique single and dual anchor screw/cord applications.

A bone positioning guide may be used as part of a bunion correction procedure. The bone positioning guide can include a bone engagement member configured to be positioned on a medial side of a first metatarsal of a foot and a tip separated from the bone engagement member by a distance effective to position the tip on a lateral side of a second metatarsal and in an intermetatarsal space between the second metatarsal and a third metatarsal. The bone positioning guide can also include a mechanism operable to reduce the distance between the bone engagement member and the tip, thereby causing the first metatarsal to move in at least a transverse plane to reduce an intermetatarsal angle between the first metatarsal and the second metatarsal.

Instruments, implants, bone plates, systems and methods for correcting bone deformities and fractures in the lower extremity are disclosed. Specifically, targeting instruments, implants, bone plates, systems and methods used for correcting bone deformities and/or fractures in the foot are disclosed.
