CANNULATED NAIL EXTRACTOR
20200222098 · 2020-07-16 · ·

A cannulated nail extractor including an extractor having a proximal end for connecting to an extraction device, a distal end opposite the proximal end, and a connector extending from the distal end. The cannulated nail extractor further includes an engagement wire having an enlarged proximal end configured to engage the extractor and an enlarged distal end configured to engage a distal end of the cannulated nail. The cannulated nail extractor further includes a positioning wire for insertion into the cannulated nail for urging the enlarged distal end of the engagement wire into engagement with the distal end of the cannulated nail, whereby exerting an extraction force on the extractor produces extraction force by engagement of the enlarged distal end of the engagement wire on the distally facing end of the cannulated nail.

Plastics implant revision and removal system

A fracture in a hollow bone is supported temporarily by a rigid plastics implant formed within a balloon within the bone. To assist implant removal, an access port, comprising a hollow cylinder, is inserted through an aperture made in an end of the bone and surrounds a proximal end of the implant. The access port is connected to a source of torsional-mode ultrasonic vibrations to soften the plastic implant and improve engagement between access port and implant. Removal of the ultrasound source allows introduction of a cutting tool through the access port, which guides it to hollow out the implant. The implant then collapses within the balloon and is withdrawn through the access port. One suitable cutting tool has a head with four helical fins separated by part-circular grooves and a concave distal face. Ultrasonically activated, the fin tips soften and cut the plastic, which flows away along the grooves.

According to embodiments, a curvature of the arc-shaped main portion (4) includes a radius of curvature r.sub.c which amounts to at least 130 mm. According to other embodiments, the tapered shape is a conical shape.

Intramedullary nail with cannulation access hole
10695109 · 2020-06-30 · ·

In one embodiment, an intramedullary nail has a nail body that has a proximal end and a distal end that are offset from one another such that the body is elongate from the proximal end to the distal end. The body has an outer surface, and an inner surface. The inner surface defines a cannulation that extends into the proximal end towards the distal end. The body defines a proximal bone-anchor hole that extends into the outer surface and entirely through the nail, and a distal bone-anchor hole that extends into the outer surface and entirely through the intramedullary nail at a location between the proximal bone-anchor hole and the distal end. The nail also defines an access hole extends into the outer surface between the leading portion and the trailing portion. The access hole terminates at the cannulation and is in communication with the cannulation.

Intramedullary pin, clamp and method of use thereof

An intramedullary pin includes a main body having a proximal boundary and a distal boundary; a curved extension having a degree of curvature of at least 1, the curved extension being in direct contact with the distal boundary; a distal cap having a cylindrical portion and a rounded portion, the cylindrical portion being in direct contact with the curved extension; a grip element having at least one contour, the grip element being in direct contact with the proximal boundary; and a proximal cap having a flat surface, the proximal cap being in direct contact with the grip element. Also disclosed is a clamp that includes a handle, two blades, a pivot, and a plurality of grasping elements including a notch, at least one protrusion, and a groove, where one or more grasping elements have a contour that is structurally complementary to the grip element in the intramedullary pin. A method of immobilizing a bone fracture using the intramedullary pin and/or clamp is also disclosed.

System and method for altering rotational alignment of bone sections
10646262 · 2020-05-12 · ·

A rotational correction system includes an implant having first and second sections, the implant having a rotatable permanent magnet disposed in a housing of the first section, the rotatable permanent magnet mechanically connected to a nut operatively coupled to the second section. A keyed portion is interposed between the nut and one or more non-linear grooves disposed on an inner surface of the housing. An external adjustment device having at least one rotatable magnet configured to rotate the rotatable permanent magnet of the implant is part of the system. Rotation of the rotatable permanent magnet of the implant in a first direction effectuates a clockwise change in the rotational orientation of the first section relative to the second section and rotation of the rotatable permanent magnet of the implant in a second direction effectuates a counter-clockwise change in the rotational orientation of the first section relative to the second section.

SYSTEMS, APPARATUSES, AND METHODS FOR CORRECTING A BONE DEFECT

An implant having a unitary body includes an intramedullary portion and an extramedullary portion. The intramedullary portion is sized and structured to be received within an intramedullary canal of a first bone and defines a longitudinal axis. The extramedullary portion includes a surface defining an axis that is disposed at an angle with respect to the longitudinal axis. An aperture defined along the extramedullary portion is sized and configured to receive a fastener therein for coupling the extramedullary portion of the implant to a second bone.

Intramedullary nail insertion handle
10631908 · 2020-04-28 · ·

In one embodiment, an intramedullary nail insertion system has a handle, a coupler, and a securement member. The handle has a body that includes a distal body end, and a proximal body end that is spaced from the distal body end along a proximal direction. Further, the handle defines an aperture that extends from the distal body end to the proximal body end. The coupler includes a distal coupler end having a first fastener that fastens to an intramedullary nail, and includes a proximal coupler end having a second fastener sized to be received through the distal body end in the proximal direction into the aperture of the handle. The securement member has a third fastener that fastens to the second fastener of the coupler so as to capture the handle body between the securement member and the intramedullary nail. The system can be assembled using a two-handed operation.
