Intersomatic cage for posterior fusion surgery to the lumbar column

摘要

Intersomatic cage for posterior fusion surgery of the lumbar column and a transforaminal implant introducer, formed by a cage (1, 8, 16) with the aim of restoring the height of the intersomatic space between lumbar vertebrae (14) with lateral windows (2) which allow the radiological control of bone growth and a vertical trough (3), which shape an interior cavity where the bone graft (5) is housed for the fusion or arthrodesis, with teeth in the shape of a saw (6) on the upper and lower part to increase the capacity for subjection and area of support between the adjacent vertebrae. Described is also the introducer (17) made up of a handle (18), a bent tube (19) through which a flexible rod (20) passes.
