The institutional review board of the university hospital approved the design (IRB approval number: 2022-04-012) and protocol of this retrospective study and waived the requirement for informed consent. We retrospectively reviewed the electrical medical records of 50 consecutive patients who had undergone BE-PCF from September 2018 to February 2021. These patients complained of posterior neck pain and radicular pain simultaneously, and underwent BE-PCF by a single orthopaedic surgeon (MS K) who was proficient in open microscopic PCF and had 1 year (49 cases) of experience with biportal endoscopic lumbar surgery but not with BE-PCF.
The inclusion criteria were as follows: (1) age between 18 and 80 years; (2) clinical manifestations and physical examinations consistent with single-level, unilateral cervical spondylotic radiculopathy, which was refractory to > 6 weeks of conservative treatment; and (3) lateral and foraminal cervical disc herniation or stenosis confirmed through magnetic resonance imaging (MRI). The exclusion criteria were as follows: (1) patients with cervical myelopathy with cord signal change upon MRI, segmental instability, and presence of hypoplasia of the lateral mass and cervical deformities; (2) patients with central localisation of the disc herniation or multi-level cervical spinal stenosis; (3) patients with prior surgery at the same level; and (4) patients who had not been followed up for > 1 year.
