Assessing health-related quality of life in patients with sciatica.

D Patrick, R Deyo, S Atlas … (1995)

This study analyzed health-related quality-of-life measures and other clinical and questionnaire data obtained from the Maine Lumbar Spine Study, a prospective cohort study of persons with low back problems. For persons with sciatica, back pain-specific and general measures of health-related quality-of-life were compared with regard to internal consistency, construct validity, reproducibility, and responsiveness in detecting small changes over a 3-month period. Data were collected from 427 participants with sciatica. Baseline in-person interviews were conducted with surgical and medical patients before treatment and by mail at 3 months. Health-related quality-of-life measures included symptoms (frequency and bothersomeness of pain and sciatica) functional status and well-being (modified back pain-specific Roland scale and Medical Outcomes Study 36-item Short Form Health Survey (SF-36), and disability (bed rest, work loss, and restricted activity days). Internal consistency of measures was high. Reproducibility was moderate, as expected after a 3-month interval. The SF-36 bodily pain item and the modified Roland measure demonstrated the greatest amount of change and were the most highly associated with self-rated improvement. The specific and generic measures changed in the expected direction, except for general health perceptions, which declined slightly. A high correlation between clinical findings or symptoms and the modified Roland measure, SF-36, and disability days indicated a high degree of construct validity. These measures performed well in measuring the health-related quality-of-life of patients with sciatica. The modified Roland and the physical dimension of the SF-36 were the measures most responsive to change over time, suggesting their use in prospective evaluation. Disability day measures, although valuable for assessing the societal impact of dysfunction, were less responsive to changes over this short-term follow-up of 3 months.

Recurrent disc herniation and long-term back pain after primary lumbar discectomy: review of outcomes reported for limited versus aggressive disc removal.

Ghazala Datoo, Jean-Paul Wolinsky, Giannina Ambrossi … (2009)

It remains unknown whether aggressive disc removal with curettage or limited removal of disc fragment alone with little disc invasion provides a better outcome for the treatment of lumbar disc herniation with radiculopathy. We reviewed the literature to determine whether outcomes reported after limited discectomy (LD) differed from those reported after aggressive discectomy (AD) with regard to long-term back pain or recurrent disc herniation. A systematic MEDLINE search was performed to identify all studies published between 1980 and 2007 reporting outcomes after AD or LD for a herniated lumbar disc with radiculopathy. The incidence of short- and long-term recurrent back or leg pain and recurrent disc herniation was assessed from each reported LD or AD cohort and the cumulative incidence compared. Fifty-four studies (60 discectomy cohorts) met the inclusion criteria, reporting the outcomes of 13 359 patients after lumbar discectomy (LD, 6135 patients; AD, 7224 patients). The reported incidence of short-term recurrent back or leg pain was similar after LD (mean, 14.5%; range, 7-16%) and AD (mean, 14.1%; range, 6-43%) (P < 0.01). However, more than 2 years after surgery, the reported incidence of recurrent back or leg pain was 2.5-fold less after LD (mean, 11.6%; range, 7-16%) compared with AD (mean, 27.8%; range, 19-37%) (P < 0.0001). The reported incidence of recurrent disc herniation after LD (mean, 7%; range, 2-18%) was greater than that reported after AD (mean, 3.5%; range, 0-9.5%) (P < 0.0001). Review of the literature demonstrates a greater reported incidence of long-term recurrent back and leg pain after AD but a greater reported incidence of recurrent disc herniation after LD. Prospective, randomized trials are needed to firmly assess this possible difference.
