This article discusses the need for theoretical foundations in epidemiological research of musculoskeletal conditions and suggests the use of biopsychosocial theory when designing epidemiological studies. The association between smoking and back pain is used as an example. ⋯ Biopsychosocial theory is well suited for public health and epidemiological studies on musculoskeletal conditions, such as the relation between back pain and smoking, and may be useful to address the multivariable inputs for this association. Although it is not a perfect model, it provides theoretical guidance to inform the research question, an element of research design that is lacking in modern-day epidemiologic reports.

Effect of An Annular Closure Device (Barricaid) on Same Level Recurrent Disc Herniation and Disc Height Loss After Primary Lumbar Discectomy: Two-Year Results of a Multi-Center Prospective Cohort Study.
Prospective cohort study. ⋯ Implantation of a novel annular repair device was associated with greater maintenance of disc height and improved one-year leg pain, back pain, and low-back disability. Recurrent disc herniation did not occur in any patients after annular repair. Closure of annular defect after lumbar discectomy may help preserve physiologic disc function and prevent long-term disc height loss and associated back and leg pain.

Randomized Controlled Trial Multicenter Study
Peripheral nerve field stimulation for the management of localized chronic intractable back pain: results from a randomized controlled study.
Improved device technology has caused a renewed interest in peripheral nerve field stimulation (PNfS). This study sought to obtain preliminary estimates of the safety and efficacy of PNfS in patients with localized chronic intractable pain of the back. ⋯ A total of 44 patients were enrolled at five sites. Of these patients, 32 were implanted with a trial system and 30 completed phase I. During phase I, there were significant differences in mean VAS scores between minimal stimulation and subthreshold stimulation (p = 0.003), low frequency stimulation (p < 0.001), and standard stimulation (p < 0.001). Twenty-four patients were classified as responders to the therapy, and 23 patients received permanent system placement. Significant differences in VAS scores were observed between baseline and all follow-up visits during phase II (p < 0.001) CONCLUSIONS: The results provide evidence to support safety and effectiveness of PNfS as an aid in the management of chronic, localized back pain.
