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

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. 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. 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.
