An extracorporeal bone compressing link and apparatus and method using same. Active devices that incorporate the extracorporeal bone compressing link can transport and compress bone through external means by acting on conventional bone fasteners including but not limited pins or wires that penetrate through the skin and fixate into bone.

A device, kit, and method for the treatment of anatomical joint dysfunctions, and more particularly, to a spring hinge comprising: a primary coil spring having a helical structure with a central cavity, wherein the primary coil spring forms a plurality of spirals layered against one another when the primary coil spring is in an unexpanded state; wherein the primary coil spring comprises surfaces that are configured to nest against each other to resist translational or shearing movement between adjoining spiral layers.

The present application discloses embodiments related to an external bone fixation device configured to correct bone deformities or repair bone injuries. The device can include a plurality of bases configured to be attached to portions of a bone and a plurality of struts configured to be adjustable in length to change the position and orientation of the plurality of bases and the attached bone portions.

A tensegrity external fixation system utilizes a tensegrity external fixator having a compression portion and a tension portion that create a force to distract bone. A tensegrity external fixator has a compressor assembly with an extension that is compresses by a tension element, such as a tension band. In an embodiment, the tension band is coupled with a bone via a stud that is attached to the bone. The tension band may extend through a stud retainer, such as a loop coupled with the stud. A single extension may be used and compressed to cause the extension to bow between a tension band or wires. In an exemplary embodiment, a compressor assembly has a compression element that is compressed by the one or more extensions. Two extensions may extend from a compressor coupling having a compression element and manipulation of the extensions may place the compression element in compression.

This invention is a method and tool for measuring and correcting deformities during osteotomy and treatment of fractures. The tool designed to restoring, alignment and correcting deformities of bone and joints is based on preoperative imaging and calculation of the deformity angle and planning for the deformity correction, the tool has a mechanism and power to force the bone to move according to the planning trajectory aiming at normal alignment during osteotomy and treatment of fracture and dislocation, it has a gauge to measure the degree of correction and the value of the bone displacement needed to overcome the bone overlapping and deformity angle in the fracture zone.

A reduction device correction system for spinal surgery comprising two uniplanar clamps; a reduction rod having opposite pitch threaded ends, the reduction rod configured to be attached to each of the two uniplanar clamps; a stabilizing rod configured to be attached to each of the two uniplanar clamps; two provisional spine rods, each configured to be attached to a respective uniplanar clamp; and an adjustable force compression device comprising a constant force cable, the constant force cable configured to be attached to each of the two uniplanar clamps.

Dynamization devices and methods of use are provided. A dynamization device may comprise first and second modules that are mated together in a substantially cylindrical shape. The outer surface of the first and second modules are connected to deformable rings that may be deformed when a longitudinal force is applied to the first and second modules. The deformation of the rings creates a longitudinal mechanical bias in the device to return it to its original shape. The strength, spring coefficient, and size of the dynamization device can be adjusted depending upon the particular needs of the application.

An external fixation K-wire clamp including an elongated channel arranged and configured to receive one or more K-wires. In some examples, the elongated channel is devoid of any predefined grooves so that the one or more K-wires can be positioned anywhere along the length of the elongated channel and/or in various orientations. In addition, and/or alternatively, an exemplary method of use for treating a distal radius fracture is disclosed.

A dynamic strut for external fixation constructs has first and second sub-struts that are axially adjustable in length and rotational position relative to one another, with the first sub-strut supporting a first dual universal joint with a first attachment peg for connection to an external fixator, and the second sub-strut supporting a second dual universal joint with a second attachment peg for connection to an external fixator. The first and second dual universal joints each include first and second ball-and-socket joints, whereby the associated attachment peg is adjustable in orientation. Set screws fix orientation of the attachment peg relative to the first ball-and-socket joint and the housing. Angular orientation of the first dual universal joint is fixed while angular orientation of the second dual universal joint is adjustable. The second sub-strut supports an axially movable shaft that supports the second dual universal joint. An adjustor allows the first and second sub-struts to axially translate relative to each other to increase or decrease length.

An external bone fixation system includes a first platform which is a ring around the limb holding a segment of bone, a second platform which is another ring around the limb holding another segment of bone, interconnected with six length-adjustable telescoping custom-assembled struts using connecting elements in the form of strut connectors consisting of pivoting and rotating holders that allow three degrees of rotational freedom for each strut.
