[Neurosurgical treatment of complications of intra-disk injections of triamcinolone hexacetonide. Value of a radio-clinical classification].
Epidural granulomas following intra-discal injection of triamcinolone hexacetonide are a well-known complication of this procedure, which is still encountered, even if its utilization was discontinued several years ago. According to the results of their experience, the authors propose a new radio-clinical grading system: grade I: disc calcification with aspect of "sub-ligamentar hernia" on CT scan; grade II: ascendant or descendant retrosomatic migration of distal content; grade III: pseudotumoral epidural infiltrate producing progressive narrowing of the spinal canal with neurological disturbance. Surgical indications in these cases can be drawn from their evolution: posterior approach can be used, with or without laminectomy, for excision as complete as possible of the involved disc (grades I and II); anterior approach should be preferred in cases of multiples recurrences after medical treatment and failure of classical posterior approach, or in case of necrotico-inflammatory proliferation with narrowing of the spinal canal (grade III).
