The present invention relates to a hydraulic, electric, remotely controlled device, which will act as internal distractor to correct spinal deformitites, and/or to lengthen long bones in humans. The object of the present invention is to provide an internal distractor that is totally different from those currently in existence on the market and one which successfully solves the problems and improves the results achieved with distracters and devices currently used for this purpose, but which have limited results, and many problems inherent in current devices. This object will be achieved by virtue of the novel design thereof and the way in which the distractor operates, which is likewise novel, and because the distractor has features that combine the advantages of various devices and techniques in existence on the market for the same purposes.
