Abstract : Objective: : Posterior stabilization of the occipitocervical junction, the upper and lower cervical spine (C-spine), and the upper thoracic spine (T-spine) using the Cervi-Fix® rod system, a modular tension band system made of titanium. Various connectors are attached to the pliable rod. 3.5-mm screws are inserted through the connectors into the occiput and into each motion segment of C- and T-spine in an optimal position. Indications: : Occipitocervical and upper C-spine instabilities (malformations, tumors, infections, aseptic inflammatory lesions, posttraumatic conditions). Instabilities of the lower C-spine on the condition that the anterior column is intact (iatrogenic, posttraumatic instabilities caused by degenerative or inflammatory processes, tumors). Degenerative or posttraumatic painful conditions of the lower C-spine. Additional posterior stabilization after anterior spondylodesis of the C-spine or upper T-spine. Contraindications: : Absent stability of the anterior column due to vertebral body destruction caused by trauma, infection, or tumors. Surgical Technique: : Insertion of screws into the occiput and/or into the lateral masses or pedicles of the C-spine or upper T-spine depending on the level to be fused. Adaptation of rods and their attachments to the screws with the help of connectors. Addition of autogenous cancellous bone grafts. Results: : The CerviFix® system was used for various pathologic conditions in 54 patients (26 women, 19 men, average age 59 years). Average duration of follow-up of 47 patients was 20 months. Bony fusion was obtained in all. We did not see any implant-associated complication
