| 摘要 |
The intervertebral implant consists of a flattened shaped hollow element (1) in the form of a hollow cylinder, hollow truncated cone, hollow truncated pyramid or hollow truncated wedge, with an outer surface (2) comprising a flattened upper bone-contact face (3), a flattened lower bone-contact face (4) and two lateral faces (5). The upper and lower bone-contact faces (3, 4) can be compressed elastically towards the inner chamber (6) of the element (1) in such a way that the maximum distance H between the upper and lower bone contact faces (3, 4) can be reduced by 0.5-5.0 mm.
