Experience with the use of the surgibone graft in anterior cervical interbody fusion employing the Cloward technique in 15 cases of the fracture-dislocation is reported.

The surgibone, manufactured from the bone of young calves, is heterogenous material that consists only of fibrils and crystallites.

With use of surgibone, iliac osteotomy is unnecessary, and this procedure is no problem of donor site pain and infection which can be possible in interbody fusion with iliac bone and rib graft and the aims of the operations are achieved, namely removal of the disc, fixation of the spine to prevent compression of the neurak tissues and stability of the spine.

The operative procedure is simplified and the time required for the operation is diminished, comparing to autogenous bone graft.

The sequelae of unstable fracture of the cervical spine were tragic. The first objective of treatment is protection of the spinalcord during reduction and stabulization. Since 1933, skeletal traction which was introduced by Crutchfield and modified by Vinke, Barton and others, has been used for reduction of fracture-dislocation of the cervical spine. 4 cases of fracture and dislocation of the cervical spine were treated at this department. 2 cases of them, one was quadriplegic and the other revealed nerve root irritation sign, were performed posterior spine fusion and recovered. The third who had fracture-dislocation between C5 and C6 with ankylosing spondylitis was died in the early course. The 4th who hadfracture-dislocation between C5 and C6 with transsection of the spinal cord was also died at home 7 weeks after trauma.
