Platzhalter mit einstellbarer axialer Länge

摘要

The present invention relates to a spacer intended for insertion between two vertebra bodies and having an adjustable axial length. The spacer comprises a first sleeve-type part (1) as well as a second part (2) which is introduced into the first one so as to be capable of axial sliding movement relative to said first part. The second part (2) is used for adjusting the total length and has a radially extending section provided on its outer portion facing the first part (1). This section includes a perforation grid (18) while the first part (1) includes a contact member (23) which co-operates with said perforation grid (18) in order to provide for displacement until the desired total length is reached.
