An orthopaedic fixation frame apparatus includes a pair of spaced apart support members such as circular rings, plates, or the like supported by a plurality of struts that span therebetween. One end of the struts adjacent the upper ring is provided with a position adjusting member that forms an interface between the support member and one end of the struts. The position adjusting members include joints (e.g., universal joints) for enabling angular change between the position of the struts and the support members.

For a further understanding of the nature, objects, and advantages of the present invention, reference should be had to the following detailed description, read in conjunction with the following drawings, wherein like reference numerals denote like elements and wherein:
FIG. 1 is a perspective view of the preferred embodiment of the apparatus of the present invention;
FIG. 2 is a perspective view of the preferred embodiment of the apparatus of the present invention shown mounted to a pair of bone parts;
FIGS. 1-4 and 7 show generally the preferred embodiment of the apparatus of the present invention designated generally by the numeral 10. Fixation frame apparatus 10 includes an upper ring 11 and a lower ring 18 that are held in spaced apart relation with a plurality of support struts 19-24. The upper ring 11 has a central opening 12 through which the patient's bone B can pass during surgery as shown in FIG. 2.
Ring 11 has an inner annular surface 13 and outer annular surface 14. Ring 11 has an upper flat surface 15 and a lower flat surface 16. A plurality of circumferentially spaced openings or slots 17 extend through the ring 11 in between the upper and lower surface 15, 16. Pin connections P can be used to form connections between upper bone part B1 with upper ring 11. Similarly, pin connectors P can be used to form a connection between bone part B2 and lower ring 18. Such pin connectors P for interfacing between a ring or plate and a bone part are well known in the art. In FIGS. 1 and 5, bone parts B1 and B2 represent proximal and distal end portions of a patient's long bone that has been fractured at fracture site F.
Lower ring 18 is similarly configured to correspond to the ring 11, providing a central opening, inner and outer annular surfaces, and upper and lower surfaces. The lower ring 18 provides a plurality of circumferentially spaced apart openings or slots 17 so that the lower ends of the struts 19-24 can be attached thereto using universal joints and bolted connections.
