Embodiment Construction

[0026]Because of the unique nature of the Taylor Spatial FRAME™ fixator and the unique method of using the Taylor Spatial FRAME™ fixator, the position of a given hole relative to another hole, either on the same plate or a different plate, is very important. Indeed, we have found that the correct positioning of the holes simplifies the manufacturing and device construction processes, simplifies the method of using the device by simplifying the geometric analysis of the system, and provides a number of clinical advantages.

[0027]FIG. 1 illustrates a fixator plate in accordance with a preferred embodiment of the present invention. The plate 2 includes a circuit body portion 4 fabricated from a suitably strong and rigid material such as a metal, alloy, plastic, composite, or ceramic. The body portion 4 includes a plurality of substantially equally spaced apertures or holes 8 positioned arcuately therein. In the specific embodiment shown in FIG. 1, the center of the holes 8 form a comple...

Abstract

A plate for use in fixating the position of a first bone segment relative to a second bone segment, the plate comprising a body portion having a plurality of attachment mechanisms located therein, wherein the attachment mechanisms include: a first group of three attachment mechanisms substantially positioned within 90°-150° of one another about a circle, and preferably within substantially 120° of one another, whereby the first group of attachment mechanisms is designed to facilitate attachment of a plurality of adjustable length struts to the plate; and a second group of attachment mechanisms substantially positioned about the circle that are designed to facilitate attachment of accessories to the plate, wherein the total number of the attachment mechanisms is a multiple of three.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a plate for use as part of an external fixation device, and more particularly to a unique hole pattern within the plate.[0003]2. General Background and Description of the Prior Art[0004]Traditional circular ring external fixation devices consist of Ilizarov-type devices that are based on a circumferential external fixator system disclosed by G. A. Ilizarov during the early 1950's. The Ilizarov system includes at least two rings or “halos” that encircle a patient's body member (e.g., a patient's leg), connecting rods extending between the two rings, transfixion pins that extend through the patient's boney structure, and connectors for connecting the transfixion pins to the rings. Use of the Ilizarov system to deal with angulation, translation and rotation is disclosed in “Basic Ilizarov Techniques,” Techniques in Orthopaedics®, Vol. 5, Nov. 4, December 1990, pages 55-59.[0005]The Ilizarov...
