CT evaluation of the greater sciatic foramen in patients with sciatica.

Sciatic and lower extremity neurologic symptoms may be from pathologic involvement of the sacral plexus or sciatic nerve in the region of the greater sciatic foramen. Twenty-five patients were reviewed who presented consecutively over a 4 year period with sciatic symptoms secondary to pathologic changes in the greater sciatic foramen. Malignant neoplasm alone (18 patients) and malignant neoplasm associated with infection (two patients) account for most of these cases. Neurogenic tumors (three patients), both benign and malignant, and infection alone (three patients) were less frequent. Although sciatic symptoms usually derive from spinal abnormalities, the evaluation of sciatic symptoms should not be considered complete without CT scanning of the greater sciatic foramen.

[Sciatica caused by synovial cysts and lumbar articular diverticula with intraspinal development. Saccoradiculographic, computed tomographic and arthrographic study].

The authors report 8 cases of patients with synovial cysts (3 cases) or diverticuli (5 cases) of the lumbar joints, compressing the sciatic roots. They describe the radiological aspects of the two sides of the degenerative pathology of the posterior articular processes, which are relatively unrecognized (14 cases in the literature). They insist on the advantage of saccoradiculography which is the only test to be able to demonstrate dynamic alterations in relation with diverticuli, if performed in a standing position. The authors show the advantage of tomodensitometry which supports the diagnosis of cyst in the presence of a fibrous wall image. They emphasize the value of the arthrography of the posterior joint; it presents a diagnostic role by visualizing the cavities, and a therapeutic role by permitting the injection in situ of steroids and/or local anesthetics.

[Treatment of sciatica with injection of hydrocortisone into the sacral hiatus].

A group of 305 patients was treated with injections of corticosteroids into the epidural space of the sacral canal through the sacral hiatus and recumbent position on hard surface. The injections were done every second day giving seven times hydrocortisone acetate 0.025 g and as the last injection Depo-Medrol 0.04 g (Upjohn) was administered. The control group comprised 324 cases treated by various other methods. The assessment of the results was based on two criteria: duration of hospital stay, and percent of patients referred for surgical treatment. In the control group the duration of hospital stay was 20 days, and 16.1% of patients were referred for surgical treatment. In the studied group these values were 17.5 days and 5.2%. Conclusion. In acute ischalgia administration of hydrocortisone and depo-medrol into the epidural space through the sacral hiatus and lying on hard surface shorten the duration of strong pain and reduce the indications to surgical intervention.
