Embodiments of the present disclosure includes method and devices for minimally invasive spinal fusion surgery. A method for minimally invasive spinal fusion surgery can include accessing a spinal column through a working channel device, wherein the working channel has a proximal end and a distal end, advancing the working channel so that the distal end pierces an outer layer of a vertebral disc, inserting a disc extractor through the working channel device and into the vertebral disc to cut the vertebral disc into pieces, inserting a disc blade through the working channel device and into the vertebral disc to cut the vertebral disc into pieces, using a disc rake to remove the pieces of the vertebral disc, inserting a disc shaver to clean a number of surfaces of vertebra adjacent to the vertebral disc, and inserting and implanting a disc implant in a space from where the vertebral disc was removed

Threaded sacro-iliac joint stabilization (e.g., fusion, fixation) implants and methods of implantation and manufacture. Some implants include a threaded distal region, an optionally threaded central region, and an optionally threaded proximal region. The distal, central, and proximal regions have lengths such that when the implant is laterally implanted across a SI joint, the distal region can be positioned in a sacrum, the central region can be positioned across an SI-joint, and the proximal region can be positioned in an ilium.

There is a process for correcting a bone injury, an implant for correcting the bone injury and a kit for applying the implant for correcting the bone injury. The process can be made substantially uniform with the application of a standardized kit. In at least one application the process is for correcting a bunion on a patient. The process can include applying a first drill guide to a bone, and then a second drill guide. Once the drill guides have been applied and wires have been inserted into a bone, an implant can then be applied to correct a bone injury and to allow the bone injury to heal.

System, including apparatus and methods, for ankle fusion using a device for separating a first bone and a second bone of an ankle region. In some embodiments, the device may comprise an expandable spacer including first and second bone-contacting surface regions facing away from one another and configured to be abutted with the first and second bones, respectively. A distance between the first and second bone-contacting surface regions may be adjustable to change the separation of the first and second bones. The first bone-contacting surface region may correspond to a portion of a sphere and may be configured to be disposed at least partially in a concavity formed surgically in the first bone. The expandable spacer offers improved control over the length of the lower limb and the orientation of the foot during ankle fusion surgery.

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.

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.

An orthopaedic implant system includes an orthopaedic implant having a plurality of fixation openings and a plug opening defining a plug opening diameter that is greater than a diameter of any of the fixation openings. The plurality of fixation openings include at least one first fixation opening configured to accept a fixation element inserted in a first bone and at least one second fixation opening configured to accept a fixation element inserted in a second bone. The plug opening is configured to accept a plug inserted in a joint space between the first bone and the second bone to cause compression distraction of the first bone and the second bone.

An orthopedic implant can be used for fixation of a joint or fracture and can include a tapered member and at least one fixation member. The tapered member can be configured for placement in association with one or more bone segments. The tapered member can have a longitudinally extending body that defines an upper surface portion, an opposed lower surface portion and first and second sides, where at least the first and second sides can be formed of porous metal and can have a porous metal outer surface. The at least one fixation member can be integrally formed with the tapered member and can extend laterally outwardly from the tapered member body. The at least one fixation member can be configured to secure the implant to the one or more bone segments to provide fixation of the one or more bone segments relative to the tapered member.

In one embodiment, the present invention is a method of arthrodesis or osteosyntheses of a first bone part and a second bone part, including the steps of positioning a first fixation zone of an implant in the first bone part and a second fixation zone of the implant in the second bone part, both the first and second zones made of shape-memory material and, prior to positioning the bone parts, are in an inner position; and while the first fixation zone is within the first bone part and the second fixation zone is within the second bone part, fixating the respective first and second fixation zones within the respective bone parts through shape-memory action at body temperature.

An implant including first and second end plates, each of which defines at least one anterior ramped surface and at least one posterior ramped surface. A posterior actuator is positioned between the first and second end plates and has guiding ramp surfaces which correspond with the posterior ramped surfaces. An anterior actuator is positioned between the first and second end plates and guiding ramp surfaces which correspond with the anterior ramped surfaces. An actuator assembly extends between the posterior actuator and the anterior actuator and is configured to selectively move the posterior actuator and the anterior actuator simultaneously, move posterior actuator independently of the anterior actuator, or move the anterior actuator independently of the posterior actuator.
