The elongated cylindrical member has a shank, a first distal threaded end and a second proximal threaded end spaced by a middle portion of the shank. A first double helical thread formed on the first distal end has a pitch equal to or greater than a second helical thread formed at the second proximal end to create a compression between the two bone segments being connected. The shank has a maximum diameter extending the length of the second proximal thread end and extends therefrom on a constant tapered slope angle through the thread of the first distal end. This creates an increasing thread depth from a start of the distal threads to a maximum adjacent a tip at the distal end of the shank.

Method and implant for bone lengthening

Номер: US20210030450A1

Автор: Alexander Nassonov

A new bone lengthening method using a force generated by own energy of a patient to activate a system based on an intramedullary telescopic nail 1 , inserted into a broken bone. An outer driving module 30 connected by a cord 29, spanning either knee or elbow or femur-hip joint, where one end of the cord 29 connected to an inner driving module of the telescopic nail inserted into a broken bone and another end of said cord connected to the outer driving module attached to the second bone. The said system converts a tensile force into an axial displacement of a distal bone segment of the broken bone. It is important to attach the outer driver 30 to an appropriate spot of skeleton in consideration that the cord starts pulling anchor 31 by active or passive leg movements only after passing 80% of natural range of motion.

It has been shown that applying traction to the spinous processes may alleviate this pain and several devices have been developed that accomplish this. However, many of these devices are either difficult to implant, do not stay in place, or wear away the bone of the spinous process due to poor conformance of the device.US Published Patent Application No. US20060122620 (“Kim I”) discloses a posterior element distraction system for implantation at a spinal motion segment comprising a superior vertebra, an inferior vertebra, each vertebra comprising a posterior element comprising a spinous process, laminal portions and a set of facet joints, and further comprising an interspinous space between the spinous processes, the system comprising: at least one lateral ...

An implant for a human rib can include an elongate body, a plurality of bores, and a placement tool interface. The elongate body can include a first portion including a flat outer face where the elongate body can be curved along a plane perpendicular to the flat outer face. The second portion can extend from the first portion to form a curved outer face. The plurality of bores can extend through the flat outer face of the first portion and into the second portion. The bores can extend partially into the curved outer face of the second portion. The placement tool interface can extend into the body. 120-. (canceled)21. A method of securing an implant to a rib bone , the method comprising:attaching a drill guide to a placement tool;rotating the drill guide to substantially align with arms of the placement tool;inserting the drill guide and the placement tool into a thoracic cavity through a thoracic opening;pivoting the drill guide to align with a posterior portion of a rib; andguiding a drill bit through a drill guide bore of the drill guide to the posterior portion of the rib.22. The method of claim 21 , further comprising:drilling a rib bore in the rib using the drill guide bore as a guide.23. The method of claim 22 , further comprising:pivoting the drill guide to substantially align with arms of the placement tool while the drill guide is within the thoracic cavity; andremoving the drill guide and the placement tool from the thoracic cavity.24. The method of claim 23 , further comprising:detaching the drill guide from the placement tool; andattaching an implant to the placement tool.25. The method of claim 24 , further comprising:pivoting the implant to substantially align with the arms of the placement tool; andinserting the implant and the placement tool into the thoracic cavity.26. The method of claim 25 , further comprising:aligning a bore of the implant with the rib bore; andinserting a fastener through an anterior side of the rib bore and into the bore of the ...

A bone plate and method for use thereof affords use of at least two surgical approaches to attach the bone plate to a fractured bone to facilitate reduction and repair thereof. The bone plate includes two domains extending in different directions from a transition zone. The directions in which each of the two domains extend are generally opposite, and the transition zone is configured to afford portions of the two domains to be substantially disposed in planes that are transverse to one another. 1. A bone plate device for facilitating reduction and repair of a fractured bone , the bone plate device comprising:a first end and an opposite second end;a first section provided adjacent the first end, a second section provided adjacent the second end, and a transition zone between the first and second sections,the first section including a first portion and a second portion, the first portion of the first section being attached to the transition zone, and the second portion of the first section being attached to the first portion of the first section and extending toward the first end,the first portion of the first section including a first side, an opposite second side, a maximum length, and a maximum width perpendicular to the maximum length and extending between the first and second sides, the maximum length of the first portion of the first section being greater than the maximum width thereof, the first portion of the first section extending along the maximum length thereof from the transition zone,the second portion of the first section including a third end, an opposite fourth end, a third side, an opposite fourth side, a maximum length extending between the third and fourth ends, and a maximum width perpendicular to the maximum length and extending between the third and fourth sides, the maximum length of the second portion of the first section being greater than the maximum width thereof, the maximum width of the second portion of the first section being disposed ...
