An implant for intersomatic fusion of two adjacent vertebrae, particularly by an operation that was performed in posterior manner. The implant has a first implant part and a second implant part that is adjustable relative to the former, for the purpose of distraction. The first implant part and the second implant part are structured so that they supplement one another, in a complementary manner, in the non-distracted state, to form a pipe that is divided in the longitudinal direction. Guide surfaces that extend radially in the distraction direction, and rest against one another are formed on the first implant part and the second implant part. The relative position of the guide surfaces is fixed in place. An instrument for the placement and distraction of the implant is also provided.

Implant and instrument for placement and distraction of the implant

The bone screw according to the invention for connection at a variable angle with a support bar for osteosynthesis, in particular a pedicle screw for implants for correcting and stabilizing a spinal column, has a threaded shaft ( ) for screwing into a vertebra ( ) and with a screw head ( ) for fixing to a support bar ( ), the screw head ( ) being formed as a partial sphere with a frustoconically tapered peg ( ) having a threaded bore ( ), the tapered peg ( ) with its threaded bore ( ) extending at an acute angle to a longitudinal axis of the threaded shaft ( ). The tapered peg ( ) is securable by means of a screw ( ) engaging in the threaded bore ( ) to a clamping sleeve ( ) forming a seat ( ) for the support bar ( ).

Orthopaedic screw variable angle connection to a longitudinal support

A skeletal fixator including implant screws, a support angularly indexed with respect to a head of the implant screws and which comprises a cavity provided with a screw thread adapted to receive a connecting rod having a screw thread of pitch different from that of the thread of the cavity. A locking screw cooperates with the head of the implant screw to clamp and bind the connecting rod relative to the implant screws.
