Open-door laminoplasty is a commonly performed procedure for the treatment of multiple level cervical spinal stenosis. One complication of this procedure is closure of the hinge and subsequent restenosis. Twinfix suture anchor was used in laminoplasty to stabilize cervical canal expansion. 53 patients with multiple level cervical spinal stenosis underwent laminoplasty. ⋯ There were four short-term complications: two were small dural-tears which were repaired intraoperatively without further sequelae, and the other 2 were both epidural hematomas that required emergent return to the operating room for evacuation. There were no Twinfix suture anchor-related complications. This Twinfix suture anchor can provide a firm and secure anchor for elevated open laminae in laminoplasty.

The instrumentation of the osteoporotic spine may sometimes result in failure due to the loosening or pullout of the conventional pedicle screw. Moreover, augmentation of screws with polymethylmethacrylate (PMMA) has risks of complications. We developed a new and original pedicle nail system with PMMA for osteoporotic vertebral fractures. ⋯ A pedicle nail system stabilizes the spinal column with osteoporosis and reduces the instrumentation failure. The technique for the insertion of the pedicle nail reduces complication from cement augmentation. The authors speculate that the strategy using the pedicle nail system for osteoporotic spine may be effective and safe when the surgery is performed through a posterior approach.

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.

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.

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.
