[Chemolysis of intravertebral disk hernia and spinal syndrome].

The authors report a 31 year old patient who underwent L5-S1 chemonucleolysis. The prenucleolysis discogram disclosed intravertebral discal displacement. Severe spinal symptoms and development of geodes in the endplates adjacent to the treated disk occurred after the procedure. This case suggests that intraosseous discal displacement may be a risk factor for postchymopapain nucleolysis discitis and may contraindicate chemonucleolysis.
