Abstract
A surgical implant (2) for fusing adjacent vertebrae (V) together comprises a body portion (4) with spaced arms (10). The body portion (4) has passages (16a and 16b) to receive surgical fixing screws (100) engaged in holes drilled in the vertebrae (V) for securing the body portion (4) to the anterior faces of the vertebrae (V) to be fused. The arms (10) extend into a prepared space between the vertebrae to be fused. Graft material is packed between the arms (10). Each surgical fixing screw (100) has an externally screw-threaded shank (101) divided into wings which can be outwardly deformed to anchor the shank (101) in the hole. Each surgical fixing screw (100) also had a head (102) which can be transformed between a laterally expanded condition and a laterally contracted condition to permit the head to be interlocked with the implant (2).
