BACKGROUND CONTEXT: Anterior cervical discectomy and fusion is a common procedure for degenerative cervical radiculopathy. In 1996, Dr. H.D. Jho reported an operative technique allowing nerve root decompression via anterior uncoforaminotomy whereas avoiding fusion. PURPOSE: To assess long-term clinical and radiological outcomes of anterior uncoforaminotomy in patients with degenerative cervical spine pathology. STUDY DESIGN: A single clinic, retrospective cohort study. PATIENT SAMPLE: Adult patients who underwent anterior uncoforaminotomy from 2013 to 2018. OUTCOME MEASURES: Clinical outcomes were assessed using VAS, NDI, SF-36 criteria. Radiological parameters included sagittal balance, disc height and White anPanjabi criterion. MATERIALS AND METHODS: All patients underwent unilateral single-level anterior uncoforaminotomy, and long-term clinical and radiologic follow up was carried out. Clinical outcomes were assessed using VAS, NDI, SF-36 criteria. Radiological parameters evaluated included sagittal balance, disc height and White and Panjabi criteria (3.5 mm of translation, 11 degrees of kyphosis). The mean follow-up period was 33.3 ± 10.6 months (range 12–57 months). RESULTS: All measures of clinical outcome improved. VAS (neck) and VAS (arm) decreased 3 [2; 4] and 5 [3; 5.2] points (median [interquartile range]), respectively (p<0.001); NDI improved from 0.38 [0.36; 0.4], to 0.29 [0.22; 0.34] (p<0.001). Two patients (6%) required additional surgery one year after operation. There were no complications in the perioperative period. Disc height decreased 0.8 mm [0.1; 2.1] (p<0.001). All patients retained stability of the cervical spine based on White and Panjabi criteria. Sagittal balance parameters did not change significantly. CONCLUSION: Uncoforaminotomy is an effective and safe method to decompress a unilateral single-level nerve root in degenerative cervical radiculopathy whereas preserving anatomy and motion of the cervical spine.
