The invention relates to an implant for the transforaminal intracorporeal fusion of lumbar vertebral column segments. At least some sections of the surface areas that are in direct contact with the spinal column are provided with an anti-dislocation mechanism (1) while an attachment part (4) for a positioning instrument (10) is provided in or on the implant and holes (6) or hollow spaces are disposed in the implant for filling purposes. According to one embodiment of the invention, the attachment part is configured as a revolute joint. In a further embodiment, the implant member has the shape of a sickle, the curvature of which is oriented ventrally and the interior of which is oriented dorsally. The attachment part is located at one end of the sickle while the opposite end of the sickle has a beak-type, tapering shape (5). At least one filling hole is provided between the sickle walls.
A method for interbody fusion of lumbar vertebral column segments, the method comprising:
An implant for the transforaminal interbody fusion of lumbar vertebral column segments, the implant comprising a main body and an engagement part, the main body including a first surface having dislocation protection elements configured for engagement with a first vertebra and a second surface situated opposite the top surface having dislocation protection elements configured for engagement with a second vertebra, the main body further including at least one side wall, and a first end portion and a second end portion situated opposite the first end portion and defining a first axis, the second end portion having a throughbore formed therein and oriented transversely to the first axis and the main body having at least one filling hole adjacent to and separate from the throughbore, wherein the engagement part includes a bolt being rotatably disposed in the transversely-oriented throughbore, the bolt defining a longitudinal axis oriented transversely to the first axis and extending between the top surface and the bottom surface, the bolt having a side wall and an insertion opening formed therein extending perpendicularly to the longitudinal axis.
