| 摘要 |
The invention relates to a device for stiffening and/or correcting a spinal section consisting of at least two vertebrae, comprising at least two screw-shaped supports (12) securable to one of the vertebrae of the spinal section to accept and secure a compression or traction shaft (32) interconnecting the supports (12). The compression or traction shaft (32) consists especially of a rod-like connecting component (20), arranged between two neighbouring supports (12) and at least one spacer (34, 34', 34'', 34''', 34'''') movably acceptable by the rod-like connector (20), arranged between two neighbouring supports (12) and spacing said supports (12) apart. The connector (20) has a thread (38) at one end (36) and, at the other end (42), also has a thread (44) or possibly a flange-like thickening (50) or the like for securing or tensioning supports (12) and spacer (34, 34', 34'', 34''', 34''''). |
