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.

Length-adjustable strut assemblies and external fixation systems utilizing such strut assemblies are disclosed. A strut assembly comprises an externally threaded rod portion including a first externally threaded rod member, and a strut barrel assembly including a strut barrel portion with an internal cavity and an adjustment portion, the rod portion extending within the internal cavity of the strut barrel portion and selectively threadably coupled with at least one key of the adjustment portion. The strut assembly further comprises a first joint assembly at an end of the first externally threaded rod member and a second joint assembly at an end of the strut barrel portion. At least one portion of the second joint is configured to be selectively disassembled from the end of the strut barrel portion to expose the internal cavity of the strut barrel portion and the second end of the rod portion.

A bone fracture fixation system including reference pins inserted into bone fragments of a patient in a first configuration and an image capture device configured to capture an image of the reference pins, and the bone fragments. The system includes a processor configured to receive and pre-process the captured image data. The processor pre-processes the image data by virtually re-positioning the reference pins in the first configuration into a second configuration, wherein the re-positioning virtually re-positions the bone fragments into normal alignment; and virtually generating a support device. The system includes a point-of-care production apparatus that produces a three-dimensional model of the virtually generated support device in a form that can be applied to the patient. The three-dimensional support device generated by the point-of-care production apparatus is configured to receive the reference pins in the first configuration; and simultaneously re-positions and fixes the bone fragments into normal alignment.

A clamping system includes a first clamp body including a first jaw, a second jaw, and a first aperture configured to receive a bone pin, the first clamp body is configured to receive a first connector rod between the first jaw and the second jaw, a second clamp body coupled to the first clamp body and including a third jaw, a fourth jaw, and a second aperture configured to receive the bone pin, the second clamp body configured to receive a second connector rod between the third jaw and the fourth jaw, and a securing assembly movable between a first position and a second position, such that moving the securing assembly from the first position to the second position reduces a distance between the first jaw and the second and reduces a distance between the third jaw and the fourth jaw.

The present invention relates to an external fixation system including at least one pair of connected clamp units forming at least one clamp. Each of the clamp units includes: a first component comprising a molded metal, the first component having a first exterior surface having a plurality of voids formed therein to define a plurality of interconnected ribs and a first periphery having at least one first pin groove formed therein; and a second component mated to the first component and including a second periphery having at least one second pin groove formed therein, the at least one first pin groove and at least one second pin groove together forming a fixation pin holder. A fixation pin is held in at least one of the fixation pin holders.

An external fixator (1) for bone fractures is proposed herein, comprising at least two support units (2, 2′) for removably supporting bone screws (3). Each support unit (2; 2) comprises: a pair of support bodies (201), which are curved; a single support pin (202) or a pair of support pins (202) fixed to only one or both support bodies (201); a pair of locking devices (5) of a bone screw (3), fixed both to the single support pin (202) or, each to a respective support pin (202).
