Effectiveness of percutaneous adhesiolysis with hypertonic saline neurolysis in refractory spinal stenosis

Abstract

The increasing proportion of elderly patients, coupled with increasing longevity, causes the problem of lumbosacral pain secondary to spinal stenosis of the lumbar spine to be an important issue. Symptoms of spinal stenosis are caused by entrapment and compression of intraspinal vascular and nervous structures; which may lead to inactivity, loss of productivity, and potential loss of independence, particularly in the elderly. Surgical decompression is considered as the natural treatment. However, the results of surgical treatments have been mixed. Results of conservative treatment are also not encouraging. While the effectiveness of caudal epidural blocks for lumbar canal stenosis was positive, the effectiveness of interlaminar epidural steroid injections showed no beneficial effects on symptomatology of spinal stenosis. Percutaneous epidural adhesiolysis with hypertonic saline neurolysis has been studied in patients with refractory low back pain secondary to post lumbar laminectomy syndrome, as well as spinal stenosis. The specific role of adhesiolysis and hypertonic saline neurolysis in the management of refractory low back and lower extremity pain secondary to spinal stenosis has not been studied. This retrospective evaluation included 18 patients derived from a total sample of 239 patients undergoing adhesiolysis and hypertonic saline neurolysis over a period of 3 years. The results showed significant improvement with reduction of pain; with improvement of physical health, mental health, and functional status. Improvement in psychological status was also noted, with decrease in narcotic intake. Epidural adhesiolysis with hypertonic saline neurolysis is a safe and probably effective modality of treatment in managing symptomatic moderate to severe lumbar spinal canal stenosis.
