Abstract
An appliance for the dynamic correction of rachidial deformities, wherein in the deformed part of the rachis which it is wished to correct is implanted a mechanical assembly of biocompatible material comprising screwed onto each vertebra of the deformed area, in the angle formed by the spinous process and the disk, a retaining clamp having at least one guidance opening from one side to the other parallel to the axis of the rachis; an elastic restoring or return structure having at least one elastic rod with a shape memory of the corresponding part of a normal rachis and introduced into the aforementioned guidance openings of the retaining clamp fixed to each vertebra, immobilized in rotation in each guidance opening and in translation on one of the retaining clamps.
Claims7
A biocompatible mechanical assembly for the dynamic correction of rachidial deformities, wherein in the deformed part of the rachis which it is wished to correct is implanted the mechanical assembly comprising, a retaining clamp fixed onto each vertebra of the deformed area, in the angle formed by the spinous process and the lamina, each retaining clamp having at least one guidance opening from one side to the other parallel to the axis of the rachis;
- and at least one springlike elastic rod in the shape of the corresponding part of a normal rachis, the rod being introduced into the aforementioned guidance openings of the retaining clamps fixed to the vertebrae, the rod being immobilized in rotation in each guidance opening and immobilized in translation on only one of the retaining clamps, said elastic rod applying a force to graually move each vertebra in said deformed area into its normal rachis position.
