Foraminal Endoscopic Discectomy In The Treatment Of Lumbar Fusion Postoperative Symptomatic Adjacent Segment Degeneration

Objective: Explore the clinical efficacy of the foraminal endoscopicdiscectomy in the treatment of lumbar fusion postoperative symptomaticadjacent segment degeneration.Methods: February2010to2011January,20cases of lumbar fusionpostoperative symptomatic adjacent segment degeneration in patients withlumbar lateral road foraminal endoscopic discectomy treatment,8males and12females; age49to61years old, average57.5years old. Lumbar fusionafter3years to10years, an average of6years and5months. Singlesegmental fusion postoperative are four cases, two segmental fusion are eightcases, three segmental fusion are seven cases, four segment fusion just onecase. Comparative analysis of20patients before surgery, postoperative1week,3months,6months,12months and the last follow-up of leg painVAS scores and the last follow-up Macnab ratings.Result:20patients all have received follow-up, follow-up time for12-23months, averaging18.3months. VAS scores compared with preoperativepostoperative low back pain were significantly reduced, the differencestatistically significant (p﹤0.05). The evaluation of Macnab score wereexcellent in10patients, good in8, fair in1, and poor in1, suggesting aneffective rate of90%(18/20).1cases of postoperative patients with recurrenceat3months, relapse rate (5%).Conclusion: Lumbar vertebrae posterior resection of nucleus pulposus ofintervertebral foramen endoscopic treatment of lumbar spine fusion surgery for symptomatic adjacent segment degeneration after satisfactory within theshort term clinical effects.
