A fusion plate (1, 20) to assist fusion of a first bone (2) and second bone (3) comprising a rigid elongated plate configured to span the joint between the first and second bones having a C-shaped profile along its length, a thickness of 0.5 to 1.5 mm, and a plurality of holes (11) to receive bone-fixing screws (12) to fix the plate to the first and second bones, wherein the plurality of holes include at least one proximal hole disposed on each side (9, 10) of a proximal end (7) of the plate configured to receive proximal bone fixing screws (12) in an orthogonal fixing screw configuration and at least one hole disposed on each side (9, 10) of a distal end (8) of the plate configured to receive distal bone fixing screws in an orthogonal fixing screw configuration. The plate may be configured for dorso-medial attachment and fusion of a meta-tarsal joint selected from a MetaTarsoPhalangeal joint (MTPJ) and a TarsoMetaTarsal Joint (TMTJ) of the big toe.

A bone implant, particularly but not necessarily, for fixing bones of the foot is provided having body in the form of a crescent or arced shaped wedge, or a wedge in the shape of a crescent or arc. The crescent shaped wedge has bone screw bores that are each configured to hold a bone screw at a particular angle for receipt in a bone, eliminating the need to also use a plate. The crescent shape provides a graft area that allows introduction and retention of bone graft material to promote bone fusion. One or both tapered sides of the crescent shaped wedge may also have teeth, serrations or the like.

Devices and methods are disclosed for joint replacement.

Implant devices and cutting clamp apparatuses and methods for creating the implants for insertion into a patient's joint to restore anatomic length and assist in final positioning of the bones following removal of cartilage and/or bone in preparation for fusion. A first implant is a biplanar implant having a shape to mimic the normal anatomical shape of the bones the implant is configured to mate with. The first implant may be cut using a cutting clamp and jig having the anatomical shape of the bones the implant will be inserted within or between. A second implant is a cylindrical piece of bone having a convex end and a concave end for mating with bones reamed to have the opposite mating surfaces. The second implant is created using cup and cone reamers having dimensions corresponding to the size of the patient's bones. Surgical methods for inserting the implants within a patient.

Implants, devices, instruments, kits and methods for correcting bone deformities in the foot are disclosed. Specifically, implants, devices, instruments, kits and methods used for lower extremity osteotomy procedures are disclosed.

Assemblies of one or more implant structures make possible the achievement of diverse interventions involving the fusion and/or stabilization of the SI-joint and/or lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. The representative lumbar spine interventions, which can be performed on adults or children, include, but are not limited to, SI-joint fusion or fixation; lumbar interbody fusion; translaminar lumbar fusion; lumbar facet fusion; trans-iliac lumbar fusion; and the stabilization of a spondylolisthesis.

At least one bone fixation device comprising a stem having a maximum outer diameter is inserted into the sacroiliac joint through a minimally invasive incision path sized approximately at or about the maximum outer diameter of the stem in soft tissue, into the iliac bone, across the sacroiliac joint and into the sacrum. The stem is inserted through the incision path to a position within the sacroiliac joint between the iliac bone and the sacrum, to fuse the sacroiliac joint, without invasive joint preparation, removal of cartilage, or scraping at or near the sacroiliac joint. Desirably, at least a portion of the stem includes a surface permitting bony in-growth.

An intramedullary assembly for intraosseous bone fusion includes a lag screw member and a tapered screw member. The lag screw member includes a first elongated body, where the first elongated body includes a first threaded portion at a first end and a bulbous portion at a second end. The tapered screw member is coupled to the lag screw member, and the tapered screw member includes a second elongated body, where the second elongated body includes a second threaded portion at a third end, and an opening at a fourth end.
