Comparative Study
Predictive validity of the Chronic Pain Coping Inventory in subacute low back pain.
The Chronic Pain Coping Inventory (CPCI) was developed to assess eight behavioral coping strategies hypothesized to be important for pain adaptation. But the predictive validity of the CPCI has yet to be tested in a longitudinal study. Here, 321 workers on sick leave after a work accident affecting the low back pain (LBP) region completed the CPCI during the subacute stage (T1) of LBP as well as the Catastrophizing scale of the Coping Strategies Questionnaire (CSQ). ⋯ Catastrophizing and Guarding were the most strongly associated with depressive mood at T1 but at T2, only depressive mood at T1 predicted this same variable. Results indicated also that the Guarding and Catastrophizing scales were able to predict future work status. The present study clearly reveals the usefulness of Guarding from the CPCI and Catastrophizing from the CSQ, when predicting different outcomes of adjustment to low back pain.

Low back pain (LBP) is a common problem that poses some interesting and difficult diagnostic problems. It is typically benign and self-limited, but it is occasionally the presenting symptom of serious systemic disease. ⋯ In the absence of these features, imaging is of limited value. Recent research has begun to evaluate subgroups with 'non-specific' low back pain that seem to benefit from specific interventions such as median branch or sacroiliac joint injections, manipulation, or specific exercises, but these require further investigation and validation.

Four important domains directly related to low back pain are: pain intensity, low-back-pain-specific disability, patient satisfaction with treatment outcome, and work disability. Within each of the domains, different questionnaires have been proposed. This chapter focuses on validated and widely used questionnaires. ⋯ For global perceived effect, we argue that the MCIC is most appropriately defined in terms of at least 'much improved' or 'very satisfied', instead of including 'slightly improved'. Finally, we argue that, from the point of view of cost effectiveness, every day of earlier return to work is important. The exact value for the MCIC can be determined, taking into account the aim of the measurement, the initial scores, the target population and the method used to assess MCIC.

The aim of the study was to evaluate validity, reliability, responsiveness and practicality of the NASS-AAOS (North American Spine Society--American Academy of Orthopaedic Surgeons) questionnaire in patients with low back pain. ⋯ The instrument is valid, sensitive to clinical changes and reliable for comparisons between groups, but further study is needed for its application in monitoring individual patients.

Clinical Trial
Transforaminal lumbar interbody fusion: a safe technique with satisfactory three to five year results.
The unilateral transforaminal approach for lumbar interbody fusion as an alternative to the anterior (ALIF) and traditional posterior lumbar interbody fusion (PLIF) combined with pedicle screw instrumentation is gaining in popularity. At present, a prospective study using a standardized tool for outcome measurement after the transforaminal lumber interbody fusion (TLIF) with a follow-up of at least 3 years is not available in the current literature, although there have been reports on specific complications and cost efficiency. Therefore, a study of TLIF was undertaken. ⋯ At the latest follow-up, significant differences of the ODI were neither found between isthmic spondylolistheses and degenerative diseases, nor between one- and multiple-level fusions. In conclusion, the TLIF technique has comparable results to other interbody fusions, such as the PLIF and ALIF techniques. The potential advantages of the TLIF technique include avoidance of the anterior approach and reduction of the approach related posterior trauma to the spinal canal.
