Surgical treatment for spinal metastasis is still controversial. However, with the improvements in treatment for primary tumors, the survival rate of patients with spinal metastasis is enhanced. At the same time, surgical technique for spinal metastasis has also improved. ⋯ During the last decade, surgical treatment for spinal metastasis has increased in the United States. The overall in-hospital complication rate and hospital charges increased, whereas the in-hospital mortality rate and length of hospital stay remained stable.

Randomized Controlled Trial
Microwave diathermy for treating nonspecific chronic neck pain: a randomized controlled trial.
Although the use of deep heat therapy is widespread, there is scant literature available on its effectiveness in treating back or neck pain. ⋯ Microwave diathermy does not provide additional benefit to a treatment regimen of chronic neck pain that already involves other treatment approaches.

Total en bloc spondylectomy (TES) is a surgery designed to achieve complete resection of a malignant spinal tumor, such as spinal metastasis. Although this procedure decreases the rate of local recurrence, it is questionable whether local control prolongs a patient's survival. In cryosurgery, antitumor immunity is activated after percutaneous cryoablation of tumors. We applied this tumor-induced cryoimmunology to TES surgery and developed a "second-generation TES" that brings about TES enhancing antitumor immunity to prolong a patient's survival. ⋯ The second-generation TES using frozen tumor-bearing autograft inside a cage affords three benefits: (1) no pain at the bone harvest site, (2) shortening of operation time, and (3) decrease of blood loss. Moreover, our results show that second-generation TES provides not only a local radical cure but also a systemic immunological enhancement.

Comparative Study
A perioperative cost analysis comparing single-level minimally invasive and open transforaminal lumbar interbody fusion.
Emerging literature suggests superior clinical short- and long-term outcomes of MIS (minimally invasive surgery) TLIFs (transforaminal lumbar interbody fusion) versus open fusions. Few studies to date have analyzed the cost differences between the two techniques and their relationship to acute clinical outcomes. ⋯ MIS TLIF technique demonstrated significant reductions of operative time, LOS, anesthesia time, VAS scores, and EBL compared with the open technique. This reduction in perioperative parameters translated into lower total hospital costs over a 60-day perioperative period. Although hospital reimbursements appear higher in the open group over the MIS group, shorter surgical times and LOS days in the MIS technique provide opportunities for hospitals to reduce utilization of resources and to increase surgical case volume.

Intraoperative monitoring (IOM) using somatosensory-evoked potentials (SSEPs) plays an important role in reducing iatrogenic neurologic deficits during corrective pediatric idiopathic procedures for scoliosis. However, for unknown reasons, recent reports have cited that the sensitivity of SSEPs to detect neurologic deficits has decreased, in some to be less than 50%. This current trend, which is coincident with the addition of transcranial motor-evoked potentials, is surprising given that SSEPs are robust, reproducible responses that were previously shown to have sensitivity and specificity of >90%. ⋯ SSEP monitoring alone during idiopathic scoliosis continues to be a highly reliable method for the detection and prevention of iatrogenic injury. Our results confirm the high sensitivity and specificity of SSEP monitoring alone published in earlier literature. As such, we suggest the continued use of SSEP alone in idiopathic scoliosis surgeries. At this time we do not believe there are sufficient data to support the addition of MEP monitoring, although more studies and revised criteria for the use of MEP may provide added value for its use in the future.
