Fixation guide devices and methods for positioning and inserting an intramedullary nail are disclosed. The fixation guide devices include a frame with a first end and a second end, a compression device removably coupled to the first end of the frame, and the intramedullary nail secured to a nail attachment apparatus of the frame. An intramedullary nail including a body with a fastening end, a closed end, and at least two openings is also disclosed. A compression device includes a compression member, a knob, and a bolt secured in the knob and rotatably engaging the compression member is also disclosed. An alignment guide is disclosed and includes a base member, an alignment member, and a fixation guide. A method of inserting an intramedullary nail into two bones for fixation of the two bones is also disclosed.

Intramedullary nail fixation guides, devices, and methods of use

Intramedullary fastener

Reamer sleeves, reamer assemblies, and methods of assembling the reamer assemblies are disclosed. The reamer sleeves include a base portion with a top surface and a bottom surface and a securement mechanism extending away from the top surface of the base portion. The securement mechanism includes an opening, at least one engagement member adjacent the opening, and at least one engagement protrusion extending away from the engagement member into the opening. The opening extends through the securement mechanism to the bottom surface of the base portion. The bone reamer assembly including a reamer and a reamer sleeve removably coupled to the reamer. The reamer including a shaft with a first and second end, a cutting member coupled to the second end of the shaft, and a groove near the second end of the shaft. A method of assembling a hard tissue reamer assembly is also disclosed.

Bone implants and cutting apparatuses and methods

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.

A method for fusing bones using a guide pin and a fastener is disclosed. The method includes inserting a guide pin into two bones. The guide pin including at least one radial marking. The method also including imaging the two bones and guide pin and analyzing the position of the at least one radial marking of the guide pin relative to the two bones. In addition, the method includes selecting a fastener, inserting a drill over the guide pin, drilling an opening through at least one of the two bones, and inserting the fastener into the opening. The guide pin may include an exterior surface with a first end and a second end, a cutting edge at the first end, and at least one radial marking near the first end. A system including a guide pin, a fastener, and a drill is also disclosed.

Devices and method of achieving bone fusion

The present invention discloses an orthopedic bone plate and locking tab apparatus and method of use. The orthopedic plate includes a body with a first end, a second end, and a central portion extending between the first end and the second end, a first pair of lobes at the first end, a second pair of lobes at the second end, and a securing mechanism extending away from a bottom surface of the central portion. The securing mechanism includes a base portion projecting from the body portion of the bone plate and two opposing extension members projecting from the base portion. A method for inserting the bone plate is also disclosed.
