Lumbar translaminar fenestration for insertion of intrathecal baclofen catheter: a novel technique.

Intrathecal baclofen has long been known to be an efficacious treatment of spasticity in children with cerebral palsy. Test bolus administration is often necessary to ensure patients will benefit from this treatment. The introduction of a intrathecal catheter for test bolus administration can prove challenging in a subset of this population, particularly those who have received surgery with postoperative spinal fusion masses. We outline a novel technique of inserting a spinal catheter for test bolus administration in a patient with a postoperative fusion mass whereby a fenestration is created through the lamina using an osteotomy needle.
