Corticosteroid Infiltration of the Extradural Space

Double Blind Evaluation of Extradural Methyl Prednisolone for Herniated Lumbar Discs

“…A l l injections were performed by B.J. using the direct approach through the interspinous ligament at the level of the diw lesion as described by Barry & Hume Kendall (1962). The patients were placed on the affected side with hips and spine fully flexed.…”

“…Various administrative techniques have been employed. Extradural injection at the affected lumbar level (Barry & Hume Kendall 1962), or at the sacro-coecygeal level via the sacral hiatus (Lindblom & Salenius 1964) and via dorsal sacral foramina (Renier 1959), local intrathecal injection (Sehgal & Gardner 1960) and systemic application by the intramuscular route (Green 1975), have all been advocated. Corticosteroid infiltration of the extradural space at the affected spinal level now appears to be the mast popular technique.…”

Extradural Corticosteroid Injection in Management of Lumbar Nerve Root Compression

“…Those in the treated group received as part of their initial treatment on admission an extradural injection of 80 mg of methylprednisolone in 10 ml normal saline, given by the lumbar route as described by Barry and Kendall (1962). Those in the control group received a superficial injection into the interspinous ligament of 1 ml of normal saline, preliminary local anaesthesia being given in all cases.…”

Lumbar epidural perineural injection: a new technique

“…The effectiveness of epidural steroids in the treatment of symptoms of lumbar nerve root compression remains controversial [1,2,6,7,9,[12][13][14][15][16]. One reason for different results and ineffectiveness may be the fact that the steroids to not reach the appropriate nerve root in a sufficient concentration by conventional caudal or posterior injection techniques.…”
