Minimally invasive posterior cervical foraminotomy (MPCF) has shown comparable outcomes to those of an open approach, with shorter operation times and length of hospital stays, as well as decreased blood loss and inpatient analgesic use. This surgical technique is mainly used to treat unilateral radiculopathy due to foraminal soft disc fragments or bone spurs. Three-dimensional (3D) navigation-guidance facilitates the surgical workflow, and it is utilized in planning the incision, determining the extent of the medial facetectomy, and confirming sufficient decompression, especially in the lower cervical spine and cervicothoracic junction, where the shoulders make localization with fluoroscopy difficult. In this video, we present the case of a 49-yr-old male patient with mechanical neck pain and C8 radiculopathy due to multilevel cervical spinal stenosis with disc herniations and C7-T1 right-sided foraminal stenosis. There was loss of cervical lordosis at the upper levels. The patient underwent anterior cervical discectomy and fusion (ACDF) at the C4-5, C5-6, and C6-7 levels to treat mechanical neck pain and restore lordosis. In order to avoid an extra-level fusion and preserve motion, we performed a right-sided C7-T1 MPCF using a portable intraoperative computed tomography (iCT) scanner (Airo®; Brainlab AG, Feldkirchen, Germany), combined with 3D computer navigation to address the patient's radicular symptoms. Patient consent was obtained prior to performing the procedure.
