A humeral guide is provided that has a first portion or member configured to be positioned on a portion of a proximal humerus. The first portion or member can be configured to rest in a complementary manner on the portion of the proximal humerus. The humeral guide can be configured with apertures defining trajectories through bone, the pin trajectories being diverging in some case and in some cases being selected to enhanced support. A second portion or member and a third portion or member of the humeral guide are configured to be positioned on first and second lateral portions of the humerus distal to a location intended for resection, e.g., between an anatomical neck and a distal end of the humerus. The second and third portions or members or portions are configured to rest in a complementary manner on the first and second lateral portions of the humerus. The humeral guide can be configured to avoid soft tissue between a bone facing side and the humerus. The humeral guide can have a removeable jig portion.

Implant assemblies, systems, kits, and methods for replacing a knee joint may include a universal femoral trial component for preparing and trialing a femoral bone of a patient to receive a plurality of different femoral implant types. The universal femoral trial component may be configured to receive any of a plurality of femoral bone preparation attachments and any of a plurality of femoral trial attachments in order to facilitate the preparation and trialing of the femoral bone to receive the plurality of different femoral implant types.

An osteotome guide is provided. The osteotome guide includes a handle, a shaft within the handle and slidable to a selected longitudinal position with respect to the handle, a tool coupler attached to a distal end of the shaft for receiving a working tool, and a lock assembly to lock the shaft into the selected longitudinal position with respect to the handle.

A minimally invasive method of correcting a bunion includes performing an osteotomy to divide the metatarsal into first and second portions, creating a pocket in the first portion implanting a nail in the pocket, securing a suture to the joint capsule, tensioning the suture to align the great toe with the metatarsal, attaching the suture to the nail, and fastening the nail to the second portion. The nail includes an anchor portion for anchoring in the first portion, a head for attachment to a second portion, a passage for attachment of the suture, a first aperture for a fastener to attach the head with the first portion, and a second aperture for a fastener to attach the head with the second portion.

A medical screw surgical device includes: a surgical device main body shaped like a bar and internally formed with an insertion passage; an extension member provided in a lower portion of the surgical device main body and internally formed with a guide hole; a guide member movably provided in the guide hole of the extension member; and a firing member provided in the insertion passage of the surgical device main body and controlling the guide member to move up and down. A surgical robot having a robot arm with the medical screw surgical device includes: a support arm provided in the robot arm; a surgical device holding member provided in the support arm; and the medical screw surgical device provided in the surgical device holding member.

A separable surgical guide instrument is configured to be inserted minimally invasively into a patient's soft tissue, and includes a guide body and a guide aperture that extends through the guide body. The guide body has a distal end that includes a first distal end portion and a second distal end portion that are arranged such that at least one of the first and second distal end portions is movable with respect to the other of the first and second distal end portions between 1) a closed position whereby the first and second distal end portions are concurrently insertable into a bone fixation aperture of a bone plate, and 2) an open position whereby the first distal end portion is spaced from the second distal end portion a sufficient distance such that the first and second distal end portions are not concurrently insertable into the bone fixation aperture.

A method of inserting an intervertebral disc implant into a disc space includes accessing a spinal segment having a first vertebral body, a second vertebral body and a disc space between the first and second vertebral bodies. The method includes securing a first pin to the first vertebral body and a second pin to the second vertebral body, using the first and second pins for distracting the disc space, and providing an inserter holding the intervertebral disc implant. The method also desirably includes engaging the inserter with the first and second pins, and advancing the inserter toward the disc space for inserting the intervertebral disc implant into the disc space, whereby the first and second pins align and guide the inserter toward the disc space.

A tulip rasp comprising a body, a handle adjacent a proximal end of the body, a head adjacent a distal end of the body, the head having at least one extension, each of which has a cutting edge, and a receiving space defined by the at least one extension.

Devices and systems can be configured to guide an instrument to a target region. The guide system may include an imaging guide including a first segment, the first segment including a guide region and imaging coils surrounding the guide region; and a platform. The platform may include a first rail, a second rail disposed parallel to the first rail, and a positioning member disposed between the first rail and the second rail. The positioning member may include a positioning frame having an entry region. The positioning frame may be movably disposed with respect to the first and second rails in a first direction and a second direction that is perpendicular to the first direction. The platform may be disposed with respect to the imaging guide so that a position of the entry region is within the guide region.

A method of inserting an intervertebral disc implant into a disc space includes accessing a spinal segment having a first vertebral body, a second vertebral body and a disc space between the first and second vertebral bodies. The method includes securing a first pin to the first vertebral body and a second pin to the second vertebral body, using the first and second pins for distracting the disc space, and providing an inserter holding the intervertebral disc implant. The method also desirably includes engaging the inserter with the first and second pins, and advancing the inserter toward the disc space for inserting the intervertebral disc implant into the disc space, whereby the first and second pins align and guide the inserter toward the disc space.
