Patient Data
ACDF from C3 to C5 with C4 corpectomy is stabilized with a DOC rod device which consists of an anterior plate system with screw fixation to the vertebral bodies, complemented by adjustable rods that stabilize the cervical spine. A bone graft (probably fibula) has been placed at the site of C4 corpectomy.
Case Discussion
The DOC rod device was developed by Dupuy Acromed and was one of the first translational system. This system is engineered to allow the cephalad screws to move along a guided rail, while the caudal screws are securely anchored in a fixed position. By utilizing the DOC system, axial deformation can be finely adjusted using a cross-fixator mechanism, which permits the implant to manage the settling process with precision, offering a controlled and dynamic stabilization approach 1.
This system has been replaced by more modern systems.
