Abstract
A vertebral replacement implant for interposition in a space left by one or more at least partially removed vertebrae between adjacent intact vertebrae. The implant has a connecting body with opposite ends sized to span at least a portion of the space between the intact vertebrae and two end pieces that are provided for attachment to the opposite ends of the connecting body. For anchoring the implant into the adjacent intact vertebrae, a cutting screw blade is provided on the end pieces so that these end pieces can be screwed into the intact vertebrae. In this way, a rigid fixation of the two adjacent intact vertebrae can be obtained thus enabling fusion thereof by bone growth without the use of an additional lateral support assembly.

A vertebral replacement implant for interposition in a space left by one or more at least partially removed vertebrae between adjacent intact vertebrae, comprising a connecting body with opposite ends sized to span at least a portion of the space between the intact vertebrae, and two end pieces provided for being fixed to the opposite ends of said connecting body and comprising means for anchoring the implant into the adjacent intact vertebrae, wherein said end pieces show a hollow cylindrical portion and said anchoring means comprise a cutting screw blade projecting laterally provided on the hollow cylindrical portions of the end pieces for screwing these end pieces by rotating them into the intact vertebrae, which cylindrical portion has an open end for penetrating into a respective one of the intact vertebrae.
A vertebral replacement implant for interposition in a space left by one or more at least partially removed vertebrae between adjacent intact vertebrae in a spine, the implant comprising:
- a connecting body with opposite ends sized to span at least a portion of the space between the intact vertebrae;
- two end pieces provided for being fixed to the opposite ends of said connecting body, said end pieces show a hollow cylindrical portion;
- and
- anchoring means for anchoring the implant into the adjacent intact vertebrae, said anchoring means comprising
- a cutting screw blade projecting laterally provided on the hollow cylindrical portions of the end pieces, said cutting screw blade preventing compression and a distraction on the spine, and
- said cutting screw blade for screwing said end pieces into the intact vertebrae,
- wherein said cylindrical portion has an open end for penetrating into a respective one of the intact vertebrae.
