IMPLANT FOR OSTEOSYNTHESIS DEVICE, IN PARTICULAR FOR CORRECTING THE VERTEBRAL COLUMN

摘要

An implant for an osteosynthesis device, in particular for correcting the vertebral column, has a lower bone anchoring part (2) and an upper part (3) that can be detachably fastened to a longitudinal support (4). The upper part (3) has an upward open channel (6) that extends backwards and defines two lateral branches (7) provided with an inner thread (10) for receiving the longitudinal support (4). In addition, a clamping part (5) for the longitudinal support (4) has a cover (11) with coaxial, outer rims (15) for enclosing the branches (7) and a coaxial inner cylinder (12) to be introduced between the branches (7). The outer surface of the envelope of the inner cylinder (12) has an outer thread (13) that corresponds to the inner thread (10) of the upper part (3).
