The objective of this study is to evaluate feasibility, accuracy and time requirements of MR/CT image fusion of the lumbar spine after spondylodesis. Sagittal MR and CT images derived from standard imaging protocols (sagittal T2-weighted MR/sagittal reformatted multi-planar-reformation of the CT) of the lumbar spine with correct (n = 5) and incorrect (n = 5) implant position were fused by two readers (R1, R2) using OsiriX in two sessions placing one (session 1) or two (session 2) reference point(s) on the dorsal tip(s) of the cranial and caudal endplates from the second lumbar to the first sacral vertebra. R1 was an experienced musculoskeletal radiologist; R2 a spine surgeon, both had received a short training on the software tool. ⋯ Mean fusion deviation (session 1/session 2; in mm) was 1.24/2.20 (R1) and 0.79/1.62 (R2). The correct/incorrect implant position was identified correctly in all cases. In conclusion, MR/CT image fusion of the spine with metallic implants is feasible, fast, accurate and easy to implement in daily routine work.

The second, internet-based multicenter study (MCSII) of the Spine Study Group of the German Association of Trauma Surgery (Deutsche Gesellschaft für Unfallchirurgie) is a representative patient collection of acute traumatic thoracolumbar (T1-L5) injuries. The MCSII results are an update of those obtained with the first multicenter study (MCSI) more than a decade ago. The aim of the study was to assess and bring into focus: the (1) epidemiologic data, (2) surgical and radiological outcome, and (3) 2-year follow-up (FU) results of these injuries. ⋯ Thus, updated results and the clinical outcome of the current operative treatment strategies in participating German and Austrian trauma centers have been presented. Nevertheless, it was not possible to answer all remaining questions to contradictory findings of the subjective, clinical outcome and corresponding radiological findings between different surgical subgroups. Randomized-controlled long-term investigations seem mandatory and the next step in future clinical research of Spine Study Group of the German Trauma Society.

As current low back pain (LBP) guidelines do not specifically advocate walking as an intervention, this review has explored for the effectiveness of walking in managing acute and chronic LBP. CINAHL, Medline, AMED, EMBASE, PubMed, Cochrane and Scopus databases, as well as a hand search of reference lists of retrieved articles, were searched. The search was restricted to studies in the English language. ⋯ Heterogeneity of study design made it difficult to draw comparisons between studies. There is only low-moderate evidence for walking as an effective intervention strategy for LBP. Further investigation is required to investigate the strength of effect for walking as a primary intervention in the management of acute and chronic LBP.

Review Case Reports
Discal cysts of the lumbar spine: report of five cases and review of the literature.
Discal cysts are rare causes of low back pain and radiculopathy. Only few reports in the literature describe these pathologies. In this article, the authors report five cases (3 males and 2 females) of lumbar discal cysts treated surgically by microdiscectomy. ⋯ Postoperatively, the complaints showed improvement, and the patients were discharged with no complications. The cases of lumbar discal cysts are described in the literature as individual case reports, therefore; the authors performed a wide systemic review of all these cases published in PubMed and MedLine, including the patients in the present report. The data of all patients were analyzed to obtain statistically based estimated information about the incidence, the epidemiology, the natural history and the optimum management of these lesions.

Randomized Controlled Trial Comparative Study
Inclusion of the fracture level in short segment fixation of thoracolumbar fractures.
Short segment posterior fixation is the preferred method for stabilizing thoracolumbar fractures. In case of significant disruption of the anterior column, the simple short segment construct does not ensure adequate stability. In this study, we tried to evaluate the effect of inclusion of the fractured vertebra in short segment fixation of thoracolumbar fractures. ⋯ The significant effect of the "including" technique on the reduction of kyphotic deformity was most prominent in type C fractures. In conclusion, inclusion of the fracture level into the construct offers a better kyphosis correction, in addition to fewer instrument failures, without additional complications, and with a comparable-if not better-clinical and functional outcome. We recommend insertion of screws into pedicles of the fractured thoracolumbar vertebra when considering a short segment posterior fixation, especially in Magerl type C fractures.
