Percutaneous Lumbar Decompression With SpineJet Hydrosurgery in the Treatment of Lumbar Spinal Stenosis Secondary to Ligamentum Flavum Hypertrophy.

INTRODUCTION: Lumbar spinal stenosis with symptomatic neurogenic claudication is a frequently encountered clinical entity which requires endoscopic or open spine surgery once the patients fail to respond to conservative therapies. In this case report we present a novel minimally invasive decompression technique using a fluid jet device (HydroCision Inc, Billerica, MA, USA) for a patient with symptomatic spinal stenosis secondary to ligamentum flavum hypertrophy. To our knowledge this approach has never been described in the medical literature.

CASE PRESENTATION: An 85 years old patient presented because of intractable right leg pain with minimal activities. She was diagnosed with significant right foraminal stenosis and she failed conservative non-invasive therapies.

CONCLUSIONS: Percutaneous lumbar hydro decompression can be a promising method for the treatment of the patients with lumbar spinal stenosis and neurogenic claudication secondary to ligamentum flavum hypertrophy.
