Abstract OBJECTIVE: Anterior cervical microforaminotomy was developed by the senior author (H-DJ) under the concept of "functional spine surgery which directly eliminates compressive pathological factors while preserving functional anatomic features. The surgical results are reported. METHODS: Among approximately 400 patients who underwent anterior cervical microforaminotomy at the University of Pittsburgh between March 1993 and May 1999, 104 patients met the inclusion criteria for this study. Forty-five patients were men and 59 were women. Patient ages ranged from 26 to 74 years (median, 46 yr). Compressive pathological lesions included spondylotic spurs in 44 cases (42.3\%), soft disc herniation in 54 cases (51.9\%), and a combination of the two in 6 cases (5.8\%). RESULTS: Eighty-three patients (79.8\%) experienced excellent results, 20 patients (19.2\%) experienced good results, and 1 patient experienced fair results. No patient demonstrated a poor or unchanged outcome. All patients demonstrated excellent decompression in their postoperative magnetic resonance imaging scans, and all patients except one with discitis maintained their motion segments well, as indicated in postoperative dynamic roentgenograms. Two patients developed transient Horner's syndrome, one patient developed transient hemiparesis, and one patient developed discitis, resulting in spontaneous bone fusion. CONCLUSION: Anterior microforaminotomy provided good or excellent outcomes, with minimal morbidities, for 98\% of 104 patients with cervical discogenic radiculopathy. The functional anatomic features were well preserved for 99\% of the patients.
