A device for external orthopedic fixations, which has one or more frames which have a substantially and/or partially annular shape and are suitable for being arranged around a limb to surround it at least partially, wherein one or more rods are fixed to a frame by means of a locking mechanism is provided. The device has two jaws which, when closed, tighten the locking mechanism to a portion of the frame by exerting a prevalently axial force, wherein the jaws are closed by means of a cam mechanism suitable for being actuated by rotating a lever pivoted to a first jaw and provided with one or more cam surfaces cooperating with a surface of the second jaw.

External fixator assemblies, systems, and methods thereof. An external fixator system may include a plurality of fixator assemblies configured to connect a plurality of pins, for example, positioned on opposite sides of a fractured bone, with one more rods. The fixator assemblies may include a plurality of clamp assemblies which are configured to rotate relative to one another when the fixator assembly is in an unlocked position.

An elastic traction system, including a driving mechanism to provide traction power, a connecting rod connected to an output shaft of the driving mechanism and rotating along with the output shaft, a traction wheel arranged at an end of the connecting rod for rotating along with the connecting rod, a traction wire connected to the traction wheel, and an elastic traction bow connected to the traction wire. An elastic body is arranged at a front end of the traction wire to be connected to various traction tools, the other end of the traction wire is wound around the traction wheel, and the traction wheel is driven by the traction system to rotate, so as to complete a traction operation. The elastic traction bow implements elastic traction of a fracture reduction surgery, provides an elastic activity space for a surgical operation, and greatly facilitates carrying out various reduction operations during traction.

An electrical insulator is applied to a bone anchor, for instance of a bone implant, such as an external fixation frame, so as to prevent undesirable temperature increases in the bone anchor and surrounding anatomical tissue when subjected magnetic resonance imaging.

An external fixation system and method for realigning, compressing or distracting broken bones has a planar ring element with an adjustable device having a body releasably mounted on the ring element. The adjustable device includes a first member for movement in a direction generally perpendicular to the ring element. A second member is mounted on the first member for movement in a direction parallel to the first member and with respect to a circumference of the planar ring element. The method includes inserting a k-wire through a first piece of bone and affixing the k-wire to the ring element. Then inserting a second k-wire through a second piece of bone and affixing the k-wire to the adjustable device second member. The pieces of bone are realigned, compressed or distracted by adjusting at least one of a first and second adjustable members forming the device.

External fixator assemblies, systems, and methods thereof.

Disclosed is an adjustable and partially removable calcaneal restraint system and treatment method in the context of a first phase of surgery wherein a transverse calcaneal pin is inserted through the calcaneus and the calcaneal restraint system is then installed pending the second surgery. An aspect of the calcaneal restraint system also provides a partially removable framework to allow better or unimpeded access to the desired site for the second surgery stage of the treatment.

Walking skates system removably coupled underneath a bottom half-ring of an external ring fixation system comprising a pair of skates, each skate of the pair of skates having a curved bottom profile from which a protruding connection body provided with at least one slot projects, the system further comprising a connecting member having a first end configured to be connected to an opening in the bottom half-ring of the external ring fixation system and a second end provided with a hole for connection to the slot in the connection body of the skate.

Pair of dynamic external fixation devices (100) for the reduction of fractures of bone fragments, said devices (100) being arranged on either side of a first bone portion traversed by a first pin (10) in a proximal position and a second bone portion traversed by a second pin (11) in distal position, while each of the dynamic external fixation devices (100) includes a first body (1) having a longitudinal axis profile (X, X), having a proximal bore (5) passing through an axis (Y, Y) in combination with the first pin (10), said first body (1) being embedded in a first coil spring (8), while said first spring (8) is nested in a second coil spring (12), mounted in conjunction with a second body mounted in conjunction on said first body (1), while the second body is mounted in conjunction with the second pin (11).
