Microsurgical anterior cervical foraminotomy (uncinatectomy) for cervical disc herniation. Report of three cases

The authors present the long-term follow-up results in three cases in which pure lateral disc herniations were surgically treated via an anterior foraminotomy (uncinatectomy) that avoided entering the disc space. The pertinent anatomical details essential for a safe approach are discussed in light of nine cadaveric neck dissections of every segment between C-1 and C-7. The surgical technique was initially studied in the cadaveric specimens and then applied in patients. The long-term results (> 2 years) in the first three patients are as good as our short-term results in another eight cases.
