Sj. Scheer et al., RANDOMIZED CONTROLLED TRIALS IN INDUSTRIAL LOW-BACK-PAIN RELATING TO RETURN TO WORK .2. DISCOGENIC LOW-BACK-PAIN, Archives of physical medicine and rehabilitation, 77(11), 1996, pp. 1189-1197
The purpose of this review was to determine the efficacy of treatments
for discogenic low back pain (LBP) by examining all randomized contro
lled trials (RCTs) of discogenic LBP published in the English language
literature between 1975 and 1993 with ''return to work'' (RTW) as the
end point. From more than 4,000 LBP citations, nearly 600 articles we
re initially reviewed; 35 studies met our selection criteria. Twenty-t
wo studies were discussed in Part 1 (Acute Interventions) or will be d
iscussed in Part 3 (Chronic Interventions). In this review, of 13 RCTs
assessing interventions for LBP with sciatica, 9 were appropriate for
their focus on, and radiologic confirmation of, discogenic LBP. The t
reatments assessed included chemonucleolysis, surgical discectomy, and
epidural steroid injection. A 26-point system to assess the quality o
f methodologic rigor was used for each article. Our literature survey
found a need for additional studies comparing surgery, conservative ca
re, epidural steroids, traction, and other approaches to determine the
ir individual effects for RTW after discogenic disease. (C) 1996 by th
