Abstract：Objective To describe the outcome of cervical microendoscopic discectomy ( CMED ) for monosegmental cervical spondylotic radiculopathy ( CSR ).Methods A retrospective study was conducted on 19 patients with cervical spondylotic radiculopathy who underwent microendoscopic discectomy from September 2010 to March 2013, and 18 patients were followed up for 12.7 months ( range: 6 - 25 months ) at the ifrst and 32.5 months ( range: 28 - 51 months ) at the end. There were 13 males and 5 females with an average age of 41.9 years ( range: 31 - 59 years ). The level of herniation was C4-5 in 4 cases, C5-6 in 9 cases and C6-7 in 4 cases. All patients had clinical presentations and ifndings on neurological examinations consistent with unilateral herniated nucleus pulposus at single-level, while no dynamic instability were found in cervical hyperextension and hyperlfexion on X-ray. Clinical efifcacy were evaluated by VAS score, JOA score, the stability and intervertebral height in lesion segment.Results VAS decreased from ( 7.12 ± 1.11 ) points preoperatively to ( 2.82 ± 0.64 ) points at discharge, to ( 1.94 ± 0.76 ) points at the ifrst follow-up and to ( 2.00 ± 0.51 ) points at the ifnal follow-up. JOA scores increased from ( 12.58 ± 1.06 ) points preoperatively to ( 15.63 ± 0.51 ) points at discharge, to ( 16.12 ± 0.72 ) points at the ifrst follow-up and ( 15.88 ± 0.78 ) points at the ifnal follow-up. The preoperative VAS and JOA scores showed signiifcant difference (P < 0.05 ) as compared with those of each postoperative time point. Intervertebral height at surgical level of preoperative and at the ifnal follow-up was ( 5.55 ± 0.52 ) mm and ( 5.39 ± 0.51 ) mm respectively, which were not signiifcantly different. (P > 0.05 ). No radiographic instability was revealed on dynamic radiographs.Conclusions With proper patient selection, posterior CEMD is safe and effective in treatment of single-level CSR with the advantage of minimal invasion and quick recovery, while its long-term outcomes require further follow-up.
