STUDY DESIGN: Fifty-one consecutive @entity1 who underwent extradural sensory rhizotomy for @entity614 after lumbar surgery were reviewed retrospectively. OBJECTIVES: To determine the effectiveness of sensory rhizotomy in the management of @entity614 in @entity1 selected by extensive imaging techniques and selective nerve root sheath injections. SUMMARY OF BACKGROUND DATA: Results of more central ablative procedures for chronic @entity158 problems have been disappointing, with variable reports of @entity158 relief. METHODS: Fifty-one @entity1 were reviewed. All @entity1 underwent extensive evaluation to exclude reversible @entity75 , and all had the diagnosis of @entity614 confirmed by results of clinical and electrophysiologic examination. Selective nerve root sheath injections under fluoroscopic guidance confirmed the symptomatic nature of the segments. All blocks were repeated at least once. All @entity1 underwent selective sensory rhizotomy or, in some cases, complete rhizotomy. After rhizotomy, 37 @entity1 were available to be observed at selected time intervals for a minimum of 2 years. Clinical results were determined by the presence or absence of @entity158 relief (visual analog scale), @entity3481 , narcotic analgesic usage, and the @entity1 's estimation of the effectiveness of the procedure. RESULTS: At 6 months after surgery, all 51 @entity1 and the outcomes of their surgery were available for review. Fifty-five percent of @entity1 rated were believed to have good or excellent outcomes, whereas the remainder had poor or failed outcomes. For the minimum 2-year follow-up period (range, 2-4.2 years), 37 @entity1 were available for review. At final follow-up examination only 19% of the @entity1 maintained good or excellent outcomes. CONCLUSIONS: The results of the rhizotomy procedures deteriorated over time. Possible reasons for the failure, other than temporal deterioration, were anatomic factors and lack of specificity of diagnostic techniques, specifically selective nerve root sheath injection. At this point rhizotomy cannot be recommended with any confidence whatsoever in the setting of @entity614 after lumbar surgery.
