Device for correcting spinal deformities
The present invention relates generally to a device of and a method for correcting spinal deformities, such as scoliosis and kyphosis. The invention employs the superelasticity or pseudoelasticity, such as found in a nickel-titanium alloy, to provide a continuous, predictable, and controllable correction force and to achieve a gradual and full correction. The correction force can be exerted on the deformed spine either at the time of the spine surgery or after the surgery or both, to afford a full correction. The continuous and controllable correction force of the present invention is safer than an instantaneous and large correction force applied only at the time of surgery. Additionally, the continuous and controllable correction force is capable of gradually and fully correcting the spinal deformities without any post-operative manipulation of the correction device or re-operation.

Title: Device for correcting spinal deformities
Usefulness: Device for correcting spinal deformities
Summary: Applicable for correction of spinal deformities including scoliosis, kyphosis, lordosis and rotation around longitudinal axis of spine.
Novelty: Correction device for spinal deformities has support member which is joined to deformed spine portion by anchor member to provide constant correction force to deformed spine portion until spine deformities are fully corrected
