A device includes a plurality of rings. Each ring has a first face, a second face, and at least one slot defined by first and second interior edges of the ring on opposing sides of the slot. The at least one slot penetrates from the first face to the second face. The first face of each ring has a first recess adjacent the slot on the first edge and a second recess adjacent the slot on the second edge. A plurality of posts join each one of the plurality of rings to an adjacent one of the plurality of rings.

A fixation system for immobilizing a skeletal structure is provided. It includes an internal fixation system having a rod-plate subsystem, a shaft subsystem, and a midfoot plate subsystem. It further includes an external fixation system adapted to connect to the internal fixation system and having a sole that provides a weight-bearing platform underneath a patient's foot to enable a patient to walk with the fixation system.

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 that are configured to clamp onto the rods. A distractor/compression instrument is used to adjust the location of a clamp assembly along the length of its rod.

The invention concerns an anatomically personalized and mobilizing external support configured to be arranged to support a physical joint between a first and a second bone group, which support comprises at least one first external auxiliary frame, which is configured to be attached to the first bone group using invasive attachment means, at least one second external auxiliary frame, which is configured to be attached to the second bone group using invasive attachment means, and at least one external auxiliary joint, which is fitted between the first and the second auxiliary frame. The external support is configured to permit a rotation of the second external auxiliary frame relative to the first external auxiliary frame about a rotational axis, sliding of the rotational axis relative to the first external auxiliary frame in a first direction, and sliding of the rotational axis or at least a portion of the second external auxiliary frame relative to the first external auxiliary frame in a second direction, which differs from the first direction.

An external fixation frame for correcting a bone deformity includes a first fixation ring and a second fixation ring. A posterior adjustable length strut couples a posterior portion of the first fixation ring to a posterior portion of the second fixation ring and has universal joint. Medial and lateral adjustable length struts couples medial and lateral portions of the first fixation ring to medial and lateral portions of the second fixation ring respectively, each of the medial and lateral adjustable length struts including a constrained hinge joint. The fixation frame also includes a half ring hingedly coupled to the second fixation ring, and an anterior adjustable length strut coupling an anterior portion of the first fixation ring to the half ring.

A device includes a plurality of rings. Each ring has a first face, a second face, and at least one slot defined by first and second interior edges of the ring on opposing sides of the slot. The at least one slot penetrates from the first face to the second face. The first face of each ring has a first recess adjacent the slot on the first edge and a second recess adjacent the slot on the second edge. A plurality of posts join each one of the plurality of rings to an adjacent one of the plurality of rings.

Various methods for treating a joint are disclosed herein. According to one method, a joint is surgically treated by performing a surgical repair treatment on tissue within the joint capsule; implanting a load reducing device at the joint and entirely outside of the joint capsule to reduce load transmitted by the treated tissue to allow for the tissue within the joint capsule to heal; and partially unloading the joint during healing of the surgical repair site.

A device includes a plurality of rings. Each ring has a first face, a second face, and at least one slot defined by first and second interior edges of the ring on opposing sides of the slot. The at least one slot penetrates from the first face to the second face. The first face of each ring has a first recess adjacent the slot on the first edge and a second recess adjacent the slot on the second edge. A plurality of posts join each one of the plurality of rings to an adjacent one of the plurality of rings.

An orthopaedic joint distractor includes a stem post defining a pivoting axis, an actuator configured to cause translational movement of the stem post, a locking sleeve holding the actuator and the stem post, a distractor arc held by the locking sleeve orthogonally to the pivoting axis and having a surface, and a first locking member held by the locking sleeve that can be advanced away from and toward the surface. The first locking member prevents rotation of the distractor arc about the pivoting axis when it has advanced a sufficient distance toward the surface.

An external fixator for mounting to a patient's leg or other anatomy to stabilize bones in the patient's leg or other anatomy includes a first ring including a first plurality a slots therein and a second ring including a second plurality of slots therein. A foot-plate has a generally U-shape and a third plurality of slots therein. A first strut is mounted between the first ring and the second ring. The first strut includes an upper tube, a lower tube, a first telescoping element securing the upper tube to the lower tube and first and second end fittings secured to ends of the upper and lower tubes, respectively. The first end fitting secures the first strut to the first ring and the second end fitting secures the first strut to the second ring.
