Abstract
Abstract This invention relates to an orthopaedic apparatus for treatment of the spine. The apparatus is comprised of a pelvic girdle being supported on at least one trochanter, an abdominal plate and two lateral shells fixed directly onto the patient by all methods. This device, which can be completed by stiff rods and a system of removable neck and head braces, enables the spinal column to be corrected in the desired direction while leaving the patient great freedom of movement.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
246 words
An orthopaedic apparatus for treatment of the spinal column, distinguished by the fact that it is comprised of the following components: a rigid pelvic girdle shaped such that it may be wrapped around the pelvis and supported by at least one of the trochanters, with a raised rear part forming the back and with two forward extremities interspaced between them so as to form a central opening, a rigid abdominal plate, generally V-shaped with rounded off corners, having its large base at the top and its small base at the bottom, whose lower end is affixed under the forward extremities of the pelvic girdle, and has in its upper part a concavity positioned such that when the apparatus is worn said concavity will be turned towards the patient's stomach, with the upper extremity finishing at the height of the xyphoid appendix; and two rigid lateral shells, each generally U-shaped and notched in the middle at top and bottom to fit one side of the patient by straddling the hip bone crest, their lower part forming a rim to be supported on the hip bone crest and with the respective forward parts of almost identical height and lower than that of the abdominal plate, both being fixed on the middle or upper part of the abdominal plate, with rear parts with a height appreciably greater than that of their respective forward parts, both fixed onto the raised rear part which forms the back of the pelvic girdle.

Claim 3
Dependent Claim
37 words
Apparatus according to claim 1, distinguished in that the pelvic girdle consists of two rigid lateral components linked together along a vertical line situated in the vicinity of the axis of the raised part forming the back.
Claim 4
Dependent Claim
22 words
Apparatus according to claim 1, distinguished by the fact that the rear parts of the two lateral shells are of identical height.
Claim 5
Dependent Claim
40 words
Apparatus as per claim 1, characterized by the fact that the rear parts of the two lateral shells vary in height, one being raised to go only along lumbar vertebrae and the other rising to the height of dorsal vertebrae.
Claim 6
Dependent Claim
34 words
Apparatus as per claim 4, characterized by the fact that one of the rigid lateral shells is composed of two parts, with the lower part having a cradle towards the inside of the apparatus.
Claim 7
Dependent Claim
85 words
Apparatus as per claim 1, characterized by the fact that it also includes a rigid metal rod with one tip resting on a cradle fixed to a part of a first component of the apparatus and the other tip on a cradle fixed to a part of a second component of the apparatus, this rod being supported between its two ends on that part of the patient's body which is opposite that on which is situated the said parts of the first and second components.
Claim 8
Dependent Claim
25 words
Apparatus as per claim 6, characterized by the fact that the rigid metal rod is adapted to be supported on a gibbosity of the body.
Claim 9
Dependent Claim
27 words
Apparatus as per claim 6, characterized by the fact that the cradle taking the tip of the rigid metal rod takes the form of a tubular slide.
Claim 10
Dependent Claim
39 words
Apparatus as per claim 1, characterized by the fact that one or several of the apparatus' components comprise support or strengthening parts in closed cell foam, designed to strengthen the corrective action of the said components on the spine.
Claim 11
Dependent Claim
42 words
Apparatus as per claim 1, characterized by the fact that the means of fixing together the various parts of the apparatus consist of studs, whose outer diameter corresponds to the inner diameter of perforations provided for in various parts of the apparatus.
Claim 12
Dependent Claim
20 words
Apparatus as per claim 1, characterized by the fact that it also includes occipito-mental support points located on the apparatus.
Claim 13
Dependent Claim
76 words
Apparatus as per claim 11, characterized by the fact that the occipito-mental support is comprised of two vertical threaded upright rods adapted to be situated in the patient's plane of symmetry and whose upper tip is linked respectively by a ring and a cradle to a chin bandage support and to a headstall and whose lower ends each rest, thanks to one or several height adustment screws, in a telescopic device fixed to the pelvic girdle.
Claim 14
Dependent Claim
70 words
Apparatus as per claim 12, characterized by the fact that each telescopic device comprises a hollow tube to receive the end of a threaded upright rod and equipped with a flange and a travel ring between which is inserted at least one spring and a guide bush, the tube and the two bushes being laid out inside a cylinder which is solid with a plate fixed to the pelvic girdle.
Claim 15
Dependent Claim
55 words
Apparatus as per claim 13, characterized by the fact that each cylinder of the telescopic devices is fixed to the girdle by an attachment system comprising a pivot pin allowing the cylinder to revolve around two perpendicular horizontal axes of which one is located when the apparatus is worn in the patient's plane of symmetry.
Claim 16
Dependent Claim
60 words
Apparatus as per claim 13, characterized by the fact that the tips of the telescopic device spring are made solid respectively with the flange and the cylinder and that the tip of the threaded upright rod and that of the tube receiving the latter are both fitted with a method preventing the rod from rotating in relation to the tube.
