M. Revel et al., FORCEFUL EPIDURAL INJECTIONS FOR THE TREATMENT OF LUMBOSCIATIC PAIN WITH POSTOPERATIVE LUMBAR SPINAL FIBROSIS, Revue du rhumatisme, 63(4), 1996, pp. 270-277
Objective, To evaluate the efficacy of forceful epidural corticosteroi
d injections in lumbosciatic pain ascribed to post-operative lumbar sp
inal fibrosis. Method. Randomized controlled study comparing forceful
injections via the sacral hiatus of 125 mg prednisolone acetate + 40 m
l saline (treatment group) and injections via the same route of 125 mg
prednisolone acetate alone (control group), Results were compared aft
er six and 18 months, The main evaluation criterion was a subjective a
ssessment of overall efficacy done by the patient using a seven-level
scale, Results, After six months, the proportion of patients who were
relieved of their sciatica was significantly higher in the forceful in
jection group (n=29; 45%) than in the control group (n=31; 19%) (p=0.0
3), Success rates for low back pain were 29% and 6% in the forceful in
jection and control groups, respectively, Among secondary efficacy cri
teria, nerve root pain evaluated on a visual analog scale and by Schob
er's index showed significantly greater improvement in the forceful in
jection group than in the control group, After 18 months, results were
still in favor of the forceful injection group, with success rates of
39% for the sciatica and 31% for the low back pain, The proportion of
patients who returned to work was similar in the two groups. Conclusi
on. Although mediocre overall, the results of forceful epidural cortic
osteroid injections are better than those of simple epidural injection
s of a corticosteroid alone. Given the paucity of effective treatments
for lumbosciatic pain apparently due to postoperative fibrosis, force
ful injections should be given a place in the treatment of this condit
ion.
