An innovative dome toe resurfacing system for performing metatarsophalangeal joint replacement is disclosed. The present invention comprises a prosthetic implant for metatarsophalangeal joint, and one or more cone extensions that covers portions of the prosthesis that extends into the metatarsal bone and phalanx bone. The cone extensions include a plurality of ridges that will catch bone on insertion and provide a press fit. The present invention also includes a cone and cup reaming system wherein one or more reamers will ream a cone/cup shape for the articular surfaces, and prepare the metatarsal and phalangeal canals for the insertion of the cone extensions. The cone extensions have ends that fit the reamed cone/cup shape wherein the cone/cup shape resembles the natural anatomy of articular surfaces of metatarsophalangeal joint.

The present disclosure provides an implant system. The implant system includes an anchor configured to be secured to bone within an excision site formed in a patients glenoid, said anchor including a shank and an enlarged head. The implant system also includes a baseplate including a body comprising: a bone facing surface; an implant facing surface; and a channel configured to extend radially from an entrance in an outer periphery of said body to a central region of said baseplate, said channel configured to receive said enlarged head and a portion of said shank and including an open region formed, at least in part, in said bone facing surface. The implant system also includes an implant including a body defining a load bearing surface and a baseplate recess, said baseplate recess configured to receive at least a portion of said implant facing surface to said baseplate such that said implant is coupled to said baseplate.

A bone shortening osteotomy apparatus is configured to provide positive retention of the bone portions as the two cut bone portions are retracted. The apparatus utilizes a bone plate with a compression block detachable attached in a fixed position and a sled assembly that is slidably engaged with the bone plate. A jacking screw extends from the sled to the compression block to draw these two components together. K-wire barrels coupled to the sled converge to direct K-wires into bone. Sled guide pins extend between the sled and the compression block and preferably on opposing sides of the jacking screw to ensure straight movement of the sled toward the compression block. A cutting guide has guide slots for guiding a cutting implement through the bone. A slot wedge may be inserted through the guide slot after cutting the bone to stabilize the cutting guide and bone for subsequent cutting.

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.

The invention comprises a method for fixating bones in the foot by aligning the bones in their desired position, inserting a screw in the aligned bones, inserting at least one transverse element near the head or tip of the screw, and tightening the screw to compress the bones. The screw comprises a shaft having first and second ends with spirally wound screw threads beginning near the first end and extending along the shaft. Advantageously, the screw is cannulated and screw threads are formed on an interior surface of the cannulation. Illustratively, the transverse elements may be staples, open-ended washers, or open-ended nuts. Reduction instruments and drill guides used in the invention are also disclosed.

A device for creating a cavity or a channel in bone. First and second steering cables are coupled to a flexible elbow or a tip of a shaft. A control assembly is operably coupled to the first and second steering cables and configured to tension one of the steering cables and slacken another one of the steering cables so as to flex the flexible elbow. The control assembly may include a steering block axially movable within a handle with a knob threadably coupled to the steering block. The steering block may be rotatably fixed within the handle. The first and second steering cables may be anchored to the steering block, such as to opposite sides of the steering block. The first steering cable may extend along a linear path, and the second steering cable may extend along a curved rib of the handle.

A coracoid drill guide assembly includes a body having a cylindrical channel on each side of the body for receiving a drill guide sleeve. The sleeves of the assembly have a 1.4 mm inner diameter to guide a 1.3 mm (or smaller) K-wire through the sleeve. An aimer arm extends from the body at a non-intersecting angle with the drill sleeve. The assembly also has a self-locking ratchet mechanism to lock the sleeve in place once the assembly has been secured to bone.

Systems and apparatus for reliably sealing a surgical device are disclosed herein. Specifically, a surgical device including a drive shaft tube that is coupled to a drive shaft is disclosed. Because the drive shaft tube is coupled to the drive shaft, the drive shaft tube rotates at the same rotational speed as the drive shaft, which is less than the rotational speed of a cannulated motor shaft. The drive shaft tube can extend through the cannulated motor shaft. In addition, a sealing member can be provided to seal between the drive shaft tube (which rotates slowly) and the motor instead of between the motor shaft (which rotates more quickly) and the motor. The sealing member can be provided in a gap defined between an outer surface of a portion of the drive shaft tube extending beyond the cannulated motor shaft and the motor.

A graft-harvesting instrument and MTP fusion device are disclosed to allow for easy and safe removal of a section of the calcaneus to be used as autograft in the fusion of the MTP joint. The graft-harvesting instrument allows a surgeon to place a barrier between the saw and the vital anatomy on the medial side of the calcaneus. The MTP fusion device allows for the exact placement of the autograft into the MTP joint. The graft-harvesting instrument allows for a very consistent piece of autograft to be harvested. The graft-retaining sleeve component of the MTP fusion device positions that autograft in place for optimum fusion of the MTP joint.
