A fixation assembly for attaching a prosthetic leg and foot combination directly to an external ring fixation assembly via a protective socket, and yet allow full adjustment of length and offset, protection of the residual stump when in use, and quick-disconnect of the socket when not in use. The device is meant for use with any existing external fixation ring assembly for fixation to a femur or tibia, and any prosthetic leg/foot combination. The fixation assembly generally includes a molded concave socket having a mounting base at its apex for mounting the prosthetic leg/foot, an articulating ring adjustably attached to the socket, and a plurality of struts there between. Each strut has a first locking pivot joint at one end pivotally attached to the articulating ring and a second locking pivot joint at an opposing end pivotally attached to the rim of the socket. The articulating ring is removably attached to the external ring fixation assembly by a plurality of detent pins for releasable attachment.

Disclosed are improved devices, systems and methods for external fixation and/or support of damaged or fractured limbs or other anatomies of a patient.

A monoplanar device for stabilizing and distracting an anatomical joint is disclosed including first and second shafts having engagement features that form a hinge joint with a single axis of rotation, the shafts being constrained by the hinge joint to move relative to one another only around the single axis of the hinge joint. The shafts and the hinge joint are disposed in a single plane with the single axis being about orthogonal thereto. A first clamp having a recess and a pin hole is slidingly disposed on the first shaft, and a second clamp having a pin hole is slidingly disposed on the second shaft. The pin holes are arranged to receive bone pins for insertion into bones adjacent to the anatomical joint. A distraction screw disposed between a threaded partial bore of the first shaft and the recess rotates to advance the first clamp along the first shaft.

This invention is a patient-specific surgical guide for percutaneous fixation of fractures designed for detection of the point of insertion, direction and angle of metal-ware (wires, screws, plates or nails). The patient-specific surgical guide seated on a bony landmark, the interior surface of the guide matches the surface anatomy of bones and fit in a single secure position for the reduction of bony or joint displacement and to insert wires or metal ware in bone and joints without need for fluoroscopic imaging. The guide comprising of a flying arc (3) with pointed introducers (1, 2) at its ends, detachable rods (27,28) and trajectory sleeves (6, 7, 24). The size and shape of the guide modified according to the nature of the anatomy of the percutaneous of bone and joints in these regions of displaced fractures of clavicle, proximal humerus, distal humerus, proximal radius and ulna, distal radius and ulna, hand bones, clavicle, patella distal fibula, medial malleolus, spine and feet bones.

A radiography aid and method of using the same comprising: attaching a radiographic reference device to the external fixation device, the radiographic reference device comprises at least two surfaces; positioning the first surface of the radiographic reference device on an imager surface to capture a first radiographic image of the external fixation device and the one or more objects; repositioning the external fixation device to position the second surface of the radiographic reference device on the imager surface to capture a second radiographic image of the external fixation device and the one or more objects that differs in position from the first radiographic image by the first angle; and calculating the position of the one or more objects in three dimensions.

An external orthopedic fixation device. The external orthopedic device includes a radius fixing member, a metacarpus fixing member, and a coupling member. The radius fixing member is configured to be secured to a radius bone of a patient. The metacarpus fixing member is configured to be secured to a metacarpus bone of the patient. The coupling member is disposed between the radius fixing member and the metacarpus fixing member. The coupling member is configured to connect the radius fixing member and the metacarpus fixing member.

A dynamic foot plate assembly structured for therapeutic use adjacent the ankle area of the body comprising a base element, at least one side element extending along the ankle area, and at least one joint movably and adjustably connecting the base element to the side element for variable displacement of the base element and side element into different operative orientations. The dynamic foot plate assembly may also comprise a plurality of strut members disposed in an interconnecting relationship between either a support member and a side element, or the support member and the base element. The strut members, if present, facilitate the variable relative displacement of the base element, side element and support member into different operative orientations.

An orthopaedic fixation assembly for prosthetic biologic attachment. The orthopaedic fixation assembly may include a main body with a longitudinally-extending stem having a proximal end, a distal end, and a cavity body. An anchor plug may be configured to be received within the stem cavity, and securable thereto via complementary mating surfaces. A spindle structure may be fixedly attached to the proximal end of the longitudinally-extending stem and protrude outwardly therefrom such that a portion of the structure extends externally beyond the resected cavity of the bone that may prevent rotational motion of the spindle. The spindle structure may have at least one compliant biasing member configured to apply a compressive force to the surrounding bone. A porous coating may be at the juncture between stem and spindle structure, on the spindle, and the splines and anti-rotation chocks, improving the initial stability of the implant and facilitating long-term bone ingrowth.

Methods and devices for approximating jaw and corresponding tissue segments are disclosed herein. In some embodiments, the approximation device includes a first jaw attachable to a first jaw segment, a second jaw attachable to a second jaw segment, the second jaw segment being smaller than the first jaw segment, and a housing. The second jaw is movably attached to the housing, the second jaw configured to move the second jaw segment toward the first jaw segment. The second jaw is configured to translate between a first position and a second position during a first segment of travel of the second jaw, and configured to at least rotate between the second position and a third position during a second segment of travel.

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.
