A surgical system and procedure are provided for correcting a deformity between first and second bones using an alignment guide based on a correction factor. The alignment guide is used to insert one or more k-wires into each of the first and second bones in a deformed configuration. A correction guide is passed along the k-wires to rotate and/or translate the first bone relative to the second bone into the corrected configuration. An auxiliary correction guide can be passed along the k-wires to further rotate and/or translate the first bone relative to the second bone from the corrected configuration to an adjusted configuration.

An instrument for use in entering bone, comprising a blade having at least two prongs and a center cannulation to accommodate a guide wire, wherein the center-cannulated guide wire allows for precise placement of the instrument within the proximal femoral neck of an individual in the treatment of certain orthopedic conditions, including those related to the surgical correction of specific deformities, particular in children and adolescents, namely, proximal femoral deformities.

An orthopedic milling machine includes an orthopedic guide pin including a bone engaging end and a burr including a hub, the burr being configured for rotation about an axis of the hub, the hub including a bore adapted to receive the orthopedic guide pin, and the burr can be moved laterally toward the guide pin at any location along the length of the guide pin until the guide pin is positioned in the bore.

A surgical guidance device is cannulated for passage of a guidewire or pin and includes a hand grip and differential control assembly for driving the guidewire or pin and differentially driving a screw, such as but not limited to a pedicle screw, into bone. The differential control assembly resides in a housing, and includes a differential control assembly for gripping and locking or releasing the guidewire or pin and effecting directional movement (relative to the user holding the surgical guidance device) either distally into the bone or proximally away from bone to thereby drive or retract the guidewire. The differential control assembly also allows distal or proximal drive of a screw, such that one or both the guidewire and screw can be passed proximally or distally alone or together.

Provided herein are methods and compositions for treating bone osteonecrosis comprising: at least one of a Gelatin tyramine (GT), a gelatin-heparin tyramine (GHT), a gelatin methacryloyl (GelMa), a gelatin acryloyl (GelAC), collagen, or a hydrogel-forming peptide that can be formed ex vivo or in situ for the treatment of bone osteonecrosis; at least one bone growth promoting agent or a macrophage depletion reagent; and optionally one or more pharmaceutically acceptable carriers.

The present invention relates generally to implants used in medical procedures such as bone fixation or fusion. More specifically, this application relates to fenestrated implants used in bone fixation or fusion.

Instruments, systems and methods for using the same for correcting bone deformities in the lower extremity are disclosed. An implant insertion and removal system, including an insertion instrument that has a body portion with a handle portion at a first end of the body portion and a coupling member extending away from the handle portion to a second end of the body portion, and an engagement member rotatably coupled to the coupling member of the body portion. Specifically, instruments and systems used for hammertoe procedures are disclosed.

An improved surgical system and procedure for correcting a deformity between first and second bones using an alignment guide based on a correction factor. The correction factor can be based on a virtual model of the first and second bones in a deformed configuration and a corrected configuration. In the virtual corrected configuration, first and second virtual axes can be fixed in the respective first and second bones. When reverted to the virtual deformed configuration, the orientation of the first and second axes can be used to determine the correction factor. The alignment guide is used to insert one or more k-wires into each of the first and second bones in a deformed configuration. A correction guide is passed along the k-wires to rotate and/or translate the first bone relative to the second bone into the corrected configuration.
