Cervical Disk Disease and the Keyhole Foraminotomy: Proven Efficacy at Extended Long-Term Follow up

TL;DRAbstract

Eighty-four consecutive patients with posterolateral cervical disk herniation treated by keyhole foraminotomy between 1980 and 1987 were reviewed. Radicular pain was the most common presenting complaint. Weakness was present in 59 patients. Sixty patients were available for long-term follow up, averaging 6.1 years. Fifty-six patients' results were graded as excellent. Three patients had good results and one fair result was noted. There were no poor results. Preoperative pain symptoms were relieved in all patients. There were no significant complications. The posterolateral keyhole foraminotomy is an efficient means of decompressing lateral soft disk herniations, without the risk of an anterior approach or iliac crest bone harvest. Careful patient selection and use of an operative microscope are essential in obtaining consistent, excellent results.
