Abstract
The present invention provides an apparatus for use in the correction of spinal deformities, such as scoliosis, by posterior surgical procedures. It has been a problem to achieve secure hooking attachment to either laminae or transverse processes due to transverse and angular displacements of the individual vertebrae; and it has been a problem to provide adequate rotational forces for correction of rotational deformities. The present invention solves these problems by the use of a carrier (88) and a hook (90) that is attached to the carrier (88) by a spherical surface (102) of an attaching portion (100), and by the use of an angular pull carrier (182) that increases the rotational correcting force of a hook (90). The principle uses of the invention include orthesis and prosthesis.
