ABSTRACT:
A vertebral locking and retrieving system comprising a locking pin, a connector, a locking component, a coupling component, a remedial component, and securing components is disclosed. The locking pin includes a threaded end and a locking end. The threaded end is adapted to be secured to a normal, healthy vertebra. The connector comprises an internally threaded bore at one end and an integrally formed plate at the other end thereof. The plate has a locking aperture adapted to non-rotatably accept the locking end of the locking pin. The locking component is engaged with the locking end of the locking pin after it has passed through the locking aperture of the plate to hold the connector onto the locking pin. The coupling component is connected one end thereof to the internally threaded bore of the connector. The remedial component is secured at one end thereof to a deformed vertebra immediately adjacent to the healthy vertebra to which the locking pin is secured or a vertebra next to the deformed vertebra and different from this healthy vertebra and is connected at its other end thereof to the other end of the coupling component. The securing components enable the remedial component to be fixedly secured to the coupling component.
