摘要:
Growth directed correction of a spine via apical vertebral control includes securing a correction system to a first vertebra and a second vertebra of the spine, the correction system defining a correction axis extending between the first and second vertebra and securing the correction system to a third vertebra intermediate the first and second vertebra, the correction system securing the third vertebra at a fixed distance from the correction axis. The correction system is secured to the first and second vertebra such that the first and second vertebra are able to grow away from one another in a direction substantially parallel to the correction axis.

摘要:
A vertebral fixing is disclosed for fixing a support structure to vertebrae in a spine during therapeutic surgery. The vertebral fixing has a screw or hook (1) by means of which it is secured to the vertebrae. An elongate threaded rod (2) extends from the screw or hook (1) to which it is coupled by means of an articulated coupling (5). A connector (3) is provided to mount onto the rod (2) whereby the vertebral fixing can be connected to a support shaft
