Bone support assembly
First Claim
1. A bone support plate for use in a bone support assembly, said bone support plate comprising:
- (a) a top surface;
(b) a bottom surface opposite the top surface and adapted to engage bone structure of a user;
(c) a fixed base portion, having first and second apertures extending therethrough, from the top surface to the bottom surface, for receiving bone fasteners therethrough;
(d) a first base cover plate recess in the top surface at said fixed base portion for receiving a base cover plate thereonto and accommodating sliding movement of such base cover plate to impose and withdraw at least partial obstruction of the first and second apertures;
(e) a slot portion, having at least third and fourth apertures extending therethrough, from the top surface to the bottom surface, for receiving bone fasteners therethrough; and
(f) a second settle cover plate recess in the top surface at said slot portion for receiving a settle cover plate thereonto and accommodating sliding movement of such settle cover plate to impose and withdraw at least partial obstruction of the third and fourth apertures.

Abstract
A bone support assembly comprising a support plate, bone fasteners, and a bone fastener cover assembly. The support plate comprises a fixed base portion comprising base apertures, and a slot portion comprising slot-shaped apertures. The bone fasteners are disposed in ones of the base apertures and the slot-shaped apertures, the bone fasteners and the support plate, in combination, being adapted and configured for holding the support plate to bone material. The bone fastener cover assembly comprises a cover plate, and at least one cover plate fastener effective to fasten the cover plate to the support plate. The cover plate and support plate, in combination, accommodate both longitudinal and transverse sliding movement of the cover plate along the top surface of the support plate to thereby cover and uncover ones of the apertures, having bone fasteners therein, while the cover plate is attached to the support plate.

8. A bone support assembly for support of bone structure, said bone support assembly comprising:
-
(a) a support plate comprising a top surface, a bottom surface adapted to engage such bone structure, a fixed base portion, and a slot portion, said fixed base portion comprising base apertures, said slot portion comprising slot-shaped apertures;
(b) bone fasteners disposed in ones of the base apertures and the slot-shaped apertures, said bone fasteners and said support plate, in combination, being adapted and configured for holding said support plate to bone material; and
(c) a bone fastener cover assembly, said bone fastener cover assembly comprising a cover plate, and at least one cover plate fastener effective to fasten said cover plate to said support plate, said at least one cover plate and said support plate, in combination, accommodating both longitudinal and transverse sliding movement of said cover plate with respect to said support plate, to thereby cover and uncover ones of said bone fasteners while said cover plate is attached to said support plate, including uncovering one of a pair of bone fasteners arranged in side-by-side relationship along the longitudinal axis of said support plate, while relatively covering the other of such pair of bone fasteners. - View Dependent Claims (9, 10)

27. A method of mounting a support to bone structure, the method comprising:
-
(a) providing a bone support assembly comprising (i) a support plate adapted to support bone structure, the support plate comprising a fixed base portion having base apertures, and a slot portion having slot-shaped apertures, (ii) bone fasteners in ones of the base apertures and the slot-shaped apertures, and (iii) a cover plate disposed over a top surface of the support plate;
(b) moving the bone support assembly into position over bone structure to be supported;
(c) sliding the cover plate, as necessary, away from a position over ones but not all of the bone fasteners thus to expose such fasteners for fastening, and fastening the bone fasteners to the bone structure; and
(d) sliding the cover plate at least partially over the bone fasteners so fastened and tightening the cover plate to the support plate thereby to prevent movement of the cover plate with respect to the fastened bone fasteners and correspondingly preventing extraction of the fastened bone fasteners from the bone structure. - View Dependent Claims (28)

29. A method of stabilizing bone structure as in claim 38, including using the settle plate to simultaneously cover, at least in part, the bone fasteners in each of at least 4 slot-shaped apertures of the slot portion, where one or both longitudinal and transverse movement of the settle plate tends to simultaneously cover a respective bone fastener in at least one aperture while uncovering another respective bone fastener in another aperture, whereby at no time are all bone fasteners in all apertures uncovered.
