Abstract
Abstract An apparatus for surgical treatment of scoliosis, comprising a framework formed by parallel struts secured at their ends by yokes and fixed on the patient's body by means of a system of belts, connected with the framework by stay rods fastened to the struts. Flexible braces serve for exerting a corrective force on the vertebrae, whose one ends are intended for attachment to the vertebrae, and the other ends are attached to mechanisms for the dosed tension of the flexible braces, secured on the struts and movable therealong.

Claim 1
Independent Claim
193 words
Apparatus for the surgical treatment of scoliosis, comprising: belt means to be strapped onto a patient's body, frame means to be situated at the exterior of the patient's body adjacent said belt means, said frame means including upper and lower yokes and upright strut means extending vertically between and fixed with said yokes, said strut means including at least one pair of upright struts for extending along both sides of the patient's trunk approximately in allignment with the spinal column, a plurality of stay rods respectively having inner ends operatively connected with said belt means and extending from said belt means outwardly toward the region of said strut means, adjustable connecting means adjustably connecting said stay rods with said strut means, flexible brace means to be secured to selected vertebrae while extending therefrom to the exterior of the patient's body, dynamometer means situated at the exterior of the patient's body and operatively connected with said flexible brace means for applying a predetermined tension thereto, and adjustable connecting means adjustably connecting said dynamometer means to said strut means, so that through said flexible brace means a corrective force can be exerted on the vertebrae.
