摘要： A bone-stiffness measuring instrument comprises a set or kit of readily assembled and adjusted components, namely a goniometer (16), a light-weight load cell (15), and a small computer package (22), adapted to continuously respond to the outputs of the load cell and goniometer and to display and/or record (i.e., store) measured stiffness data; plus hardware in duplicate, namely, a bone-screw clamp (18, 20) and bracket for fixed reference to bone-screws that are externally exposed on each of the respective sides of the fracture (following removal of an external fixator), a stiff arcuate arm member of radius at least twice the diameter of the fractured bone, and a goniometer-end mount. The arcuate arm member is adjustably fixed to the bracket for bone-screw reference, and the goniometer-end mount is also adjustably fixed to the arcuate arm member, with a releasably lockable-ball-joint connection for adjusted orientation of an end mounting to the goniometer.

摘要： A mechanism having a particular application as a bone fixator for the fixation of two substantially co-linear members (A, B), which enables the controlled pivotal motion of the two members (2, 3) in two axes. The mechanism includes a dual axis hinge (1) having two members (2, 3) that are pivotally connectable by engageable pivots (6, 7) at each end of the members (2, 3), such that the members (2, 3) may pivot with respect to each other when one of the engageable pivots is engaged and the other pivot is released. The mechanism also includes an attachable elongate column (8) having a plurality of clamps (9), to each of which is affixed a bar (10) holding a further clamp (11) which affixes a bone screw (12). The bone screws (12) are attached to different portions of the substantially co-linear members (A, B), which may be, for example, a broken bone. The mechanism may also be used to encourage free and controlled cyclic bending centred on each pivot (6, 7) when the clamps (9, 11) at either end of each of the bars (10) are released.

摘要： A set or kit of readily assembled components for measuring bone stiffness as in the case of a fractured tibia in the course of healing repair. The components comprise a unit-handling elongate stiff bar (20) with an independent pivotally suspended footing element (17, 18) at each end of the bar, a goniometer (16) having means for movably securing its respective ends to the respective footing elements, a light-weight load cell (13), and a small computer package (22), adapted to continuously respond to the outputs of the load cell and of the goniometer and to display and/or record (i.e., store measured stiffness data). In a preferred embodiment, a level-responsive device, such as an air-bubble sight (36), is fixed to the bar to facilitate and to enhance the accuracy of bone-stiffness measurement, in that the level indicator can assure use for measurements wherein the pivot axis of each footing suspension is truly horizontally oriented.

摘要： The invention serves patients having a fractured bone wherein separate parts of the bone have been immobilized by an external axial fixator, and the invention provides patient-operated mechanical structure to enable him to transiently distract spaced bone-anchored regions of the fixator. In one embodiment, the patient-operated mechanism is in the form of an accessory that is detachably mounted to the fixator; in another embodiment, the patient-operated mechanism is embodied in an external axial fixator, preferably of the so-called dynamic variety.
