OBJECT: The authors conducted a study to determine the surgery-related results and outcomes in @entity1 with @entity12897 . They emphasize several specific characteristics useful in clinical management. METHODS: Forty-six consecutive @entity1 with 54 lumbar @entity12897 underwent surgery between 1990 and 2001. A retrospective analysis of the clinical presentation and follow-up data, radiological findings, and surgical techniques was performed. Clinical presentation was dominated by acute or subacute @entity158 . No specific symptom allowed differentiation of @entity12897 from a @entity890 . Computerized tomography scanning aided in establishing the correct diagnosis in 19 of 30 cases and magnetic resonance (MR) imaging did so in all cases. Three of the 46 @entity1 presented with bilateral lumbar @entity12897 . The L4-5 level was affected in 61%, and radiological signs of @entity1797 were observed in 54% of the @entity1 . Immediate symptom relief without local recurrence was obtained by complete microsurgical excision in which @entity162 was used to remove the synovial membrane and in which the interapophysial joint was preserved. During the 1st postoperative year, a newly formed symptomatic @entity12897 developed on the contralateral side or at a superior vertebral level in five @entity1 . They underwent surgery; results were good and there was no recurrence. CONCLUSIONS: The findings in this series suggest that @entity12897 can occur at multiple lumbar sites within a short period of time and could be predisposed to developing in certain individuals, predominantly in @entity1 older than 40 years of age. Postoperative follow up is recommended and MR imaging mandatory in cases of recurrent sciatica.
