Olerud Cervical is a screw and rod fixation system for the whole cervical spine. In this article, we demonstrated our preliminary results using this system. Posterior cervical fixation by Olerud Cervical was performed on ten patients. All patients had cervical instability due to various disorders. There were rheumatoid arthritis in seven, anomaly at upper cervical spine in one, trauma in one and metastasis in one, respectively. The sites of fixation were occipitocervical in four, atlantoaxial in three, lower cervical in two and C1-6 in one, respectively. One patient with metastatic tumor of C3 died two months postoperatively. The other nine patients were followed up for more than twelve months (range, 12-23 months). Bony fusion was achieved in all of these nine patients. There were no major complications. Neither breakage nor dislodgment of implants was observed. However, removal of instruments was needed after bony fusion in one patient, because he complained of neck pain that was supposed to arise from the laterally placed rods. Our preliminary results suggested that Olerud Cervical is a useful implant for posterior cervical fixation. We noted the advantages and disadvantages of this system. The advantages were mechanical superiority available for the whole cervical spine and multiplicity of selection for screw placements, while the disadvantage was the complexity of the implants. It required a great amount of surgical skill to connect the screws and rods.
