To evaluate bilateral constant-current globus pallidus internus (GPi) deep brain stimulation using an 8-contact lead. ⋯ Constant-current GPi deep brain stimulation proved safe and efficacious for treatment of primary dystonia. Motor scores improved by 54%, mostly within the first month. No phenotype-specific stimulation could be achieved, despite the capability of the new lead to stimulate specific loci within the GPi.

Although there are many postoperative febrile causes, surgical-site infection has always been considered as one of the major causes, but it should be excluded; we encountered many patients who showed delayed postoperative fever that was not related to wound infection after spinal surgery. We aimed to determine the incidence of delayed postoperative fever and its characteristics after spinal surgery, and to analyze the causal factors. ⋯ We suggest that most spinal surgeons should be aware that postoperative fever can be common without a wound infection, despite its appearance during the late acute or subacute period.

This study critically evaluates the long-term results of standalone anterior lumbar interbody fusion (ALIF), without use of rhBMP-2, as a therapeutic option for symptomatic patients with degenerative disc disease (DDD). Furthermore, this study intends to identify predictive parameters for anterior lumbar interbody fusion outcome. ⋯ The ALIF technique is a durable treatment option for patients with DDD. This study suggests different predictive parameters for treatment outcome.

To evaluate feasibility of computed tomography (CT) coronal multiplane reconstruction image (CMRI) to determine subaxial cervical pedicle screw (PS) entry point and guide lateral vertebral notch (LVN)-referred technique for subaxial cervical PS insertion. ⋯ CMRI is reliable for determining subaxial cervical PS entry point. LVN is a consistent landmark for the notch-referred technique, which is a practical and easy to master technique for subaxial cervical spine PS insertion.

Tethered cord syndrome is a well-known complication after myelomeningocele (MMC) repair in childhood. However, late complications in adults with a repaired MMC are not well understood. In particular, the influence of a degenerative spinal deformity on a sustained tethered cord is still unclear. ⋯ In adults with a repaired MMC, lumbar canal stenosis should be investigated as a possible cause of late neurologic decline. Clinical manifestations may be complicated by the coexistence of both the original and subsequent neurologic disorders. Because these additional disorders result from compressive myelopathy, early surgical decompression is indicated to avoid irreversible spinal cord dysfunction.
