Abstract

Objectives

Posterior cervical foraminotomy is a surgical procedure used to treat unilateral cervical radiculopathy. It provides direct decompression of the nerve root without the necessity of fusion while maintaining cervical mobility. With the advancement in image-guidance technology and minimal access techniques, intra-operative CT has provided a safer, more accurate instrumentation placement with less radiation exposure to operative staff and provides better anatomical visualization quality compared to traditional intra-operative imaging techniques. This case series aims to address the applications of advanced image guidance in posterior cervical foraminotomy and describe the nuances.

Method

A technical report on a series of seven cases on intraoperative CT navigation for posterior cervical foraminotomy surgery. Posterior cervical foraminotomy was performed in all patients under CT guided navigation system without an image intensifier. In one case after the foraminotomy, the extruded disc was carefully removed by gentle retraction.

Result

From 1 January 2020 to 31 December 2021, a total of seven patients with nine cervical foraminotomy procedures were performed using the aid of CT-guided navigation. The series comprised five women and two men whose mean age was 50.6 years. In all cases, the radiculopathy symptoms were diminished significantly. There were no cases of instability on the dynamic cervical radiograph. There were no complications during the surgical procedure.

Conclusion

The navigation also allows the surgeon to localise the index level accurately and appraise the adequacy of the intended decompression in three planes of the CT scan image. The ability to perform accurate spine navigation would be the precursor for robotic spinal surgery.
