A method for applying compression to a joint includes providing an intramedullary fixation assembly having a proximal screw member positioned at a proximal end of the intramedullary fixation assembly and a lag screw member positioned at a distal end of the intramedullary fixation assembly. Medullary canals are drilled in a first and second bone and the medullary canals are reamed. The proximal screw member is inserted into the first bone and a drill is used create a dorsal hole in the first bone. The lag screw member is slideably coupled to the dorsal hole and to the proximal screw member and into the second medullary canal. A torque is applied to the lag screw member to apply compression to the joint.

A stabilization device is provided including an axle and a portion that can be affixed to a bone. The device is used to stabilize a joint while allowing motion of the joint along its natural trajectory and it is placed internally in order to prevent pin tract problems. Additionally, methods for using the device are provided that include, in various sequences, inserting the axle into a bone of a joint, adjusting the geometry of the device and attaching the fixable portion to another bone of the joint. The device can be provided as part of a system including an axis trajectory guide useful for locating the axis of rotation of the joint prior to insertion, adjustment and attachment of the device.

A surgical implant which includes: a first anchoring portion comprising two first arms movable between an inserting position and an anchoring position, in which the first arms are spread apart so as to be anchored in a first bone; a second anchoring portion to be anchored in the second bone; and an intermediate portion connecting the first anchoring portion to the second anchoring portion. The intermediate portion comprises: a recess; and a first connecting portion and a second connecting portion that are remote from one another. Bringing the first connecting portion and second connecting portion closer together moves the first arms from the inserting position thereof to the anchoring position thereof.

Orthopedic implants described herein are used for fractures, inter-digital fusion of the fingers, toes, and other small bones of the body, as well as other procedures. Each implant has first and second drive ends for insertion into bone. The drive ends may be on the same or separate implant component(s) and include external threading. In one form, a single component includes the first and second drive ends, while in another form, a first component has the first drive end and a second component has the second drive end. In the two component version, a head of one component receives an end of the other component to provide coupling or joining of the two components.

An anchor for an implantable device for arthroplasty can include a hollow anchor body defining an interior cannula space. A slot can extend along a length of the anchor body. The slot can provide an opening from the interior cannula space to an exterior of the anchor body. The slot can have a slot width that is smaller than an internal width dimension in the interior cannula space. The anchor can also include a rounded edge at a transition between the slot and at least one of an interior surface of the anchor body or an exterior surface of the anchor body.

A flexible connector for an implantable device for arthroplasty can include a flexible central portion. A first anchoring portion can extend from a first end of the central portion. A second anchoring portion can extend from a second end of the central portion, opposite from the first end. The first anchoring portion and the second anchoring portion can each comprise a thickened portion located farther away from the central portion and a thinner portion, relative to the thickened portion, located nearer to the central portion than the thickened portion.

System and methods for bone fusion are disclosed. The systems and method are directed to forming complementary surfaces on bones on either side of an interphalangeal joint and limiting the relative movement thereof so as to promote fusion of the joint.

The present invention relates to a device and system for surgical fixation of small bones, small bone fragments, and osteotomies and more particularly to compression screw having a threaded leading portion which is joined to a section that is free from threads, and which includes an angle or from 12 to 25 in a plane through the longitudinal axis of the screw and a portion which is joined to a head having a configuration that is intended to provide anti-rotational stability and compression through the device.

The invention relates to a computer-implemented method (200) for geometrically defining a component (214) adapted to an organism unit, comprising the steps of: determining (202) at least one adaptation variable (222) by evaluating an image (210) of the organism unit, wherein the at least one adaptation variable (222) is based on a geometric characteristic of the organism unit, and defining (204) a component geometry (218) of the component (214) based on a component base geometry adapted with the at least one adaptation variable (222).

A toe bone implant for correction of toe bone deformities is provided. The toe bone implant includes a first portion having a socket portion. The toe bone implant also includes a second portion having a ball portion operatively connected to the socket portion. The toe bone implant is implanted in a joint such that the ball portion is configured to rotate a predetermined amount respective to the socket portion.
