Understanding postsurgical prescribing patterns and their impact on persistent opioid use is important for establishing reasonable opioid prescribing protocols. We aimed to determine national variation in postoperative opioid prescription practices following elective lumbar spine surgery and their impact on short-term refill prescriptions.

The OptumLabs Data Warehouse was queried from 2016 to 2017 for adults undergoing anterior lumbar fusion, posterior lumbar fusion, circumferential lumbar fusion, and lumbar decompression/discectomy for degenerative spine disease. Discharge opioid prescription fills were obtained and converted to morphine milligram equivalents (MMEs). Age- and sex-adjusted MMEs and frequency of discharge prescriptions >200 MMEs were determined for each U.S. census division and procedure type.

The study included 43,572 patients with 37,894 postdischarge opioid prescription fills. There was wide variation in mean filled MMEs across all census divisions (anterior lumbar fusion 774-1147 umbar spine surgery.

Most microsurgical instrument designs concentrate on manipulating the targeted tissue more than the detailed design of the user's hand. Microergonomics is a new area of study on hand design in order to redesign the instruments in a better way for the surgeon's hand.

The article describes how the concept of microergonomics could improve the design of microinstruments. The penization concept is introduced, too. (R)-2-Hydroxyglutarate cell line This involves converting the instruments available to the shape of a pen, making these instruments manipulated just like the writing process.

A new design of pen needle holder is suggested, along with a new concept of integrating electronics with the instruments, revealing many possible future devices.

The future perspectives of designing neurosurgical instruments will be directed toward microergonomics, penization, and electronics integrated with surgical instrument principles.

Debate on the effectiveness of preoperative embolization for spinal metastatic lesions, especially for nonhypervascular tumors, has persisted. The present study aimed to identify the effectiveness of preoperative embolization in patients who had undergone surgery for spinal metastasis.

Two of us (Z.T. and Z.H.) independently searched the PubMed, Embase, and Cochrane Central Register of Controlled Trials databases to identify eligible clinical studies that had compared the outcomes of patients treated surgically for spinal metastatic disease with or without preoperative embolization. The primary outcomes included intraoperative blood loss, perioperative blood loss, and transfusion requirements. The secondary outcomes include the operative time, overall survival, and complication rates. Meta-analyses were performed for subgroups of hypervascular, nonhypervascular, and mixed tumors. A fixed effects model was applied when I

was <50%, and a random effects model was applied when I

was >50%.

A total hypervascular metastatic tumors to the spine.

The current data support the use of preoperative embolization for hypervascular metastatic tumors to the spine. However, little evidence is available to support the use of preoperative embolization for nonhypervascular metastatic tumors to the spine.

- Vertebral hemangiomas (VH) are benign but highly vascular lesions and are one of the most common lesions of the vertebral column. Anterior soft tissue compression of spinal cord due to vertebral body hemangioma are challenging to manage. Authors' objective was to assess long term clinical and radiological effects of direct transpedicular absolute alcohol embolization, laminectomy and short segment instrumented fusion on resolution of extra osseous epidural soft tissue and improvement in myelopathy in cases of vertebral hemangioma causing anterior soft tissue compression.

- This was a retrospective analysis that included patients with single-level vertebral hemangioma with anterior intraspinal soft tissue growth causing spinal cord compression and clinical features of myelopathy, between June 2007 and June 2019 at authors' institute. Trans-pedicular vertebral body injection of absolute alcohol, laminectomy and pedicle screw rod instrumentation was done in all patients. Clinico-radiological outcomes of su causing spinal canal compromise and myelopathy can be managed with direct transpedicular ethanol embolization, laminectomy and short segment instrumented fusion with resolution of the extra osseous soft tissue and improvement in myelopathy. The procedure is relatively simple, cost effective and has good outcome.

Anterior cervical discectomy and fusion (ACDF) is effective for the treatment of single-level cervical spondylotic myelopathy (CSM). However, the data surrounding multilevel CSM have remained controversial. One alternative is laminoplasty, although evidence comparing these strategies has remained sparse. In the present report, we retrospectively reviewed the readmission and reoperation rates for patients who had undergone ACDF or laminoplasty for multilevel CSM from a national longitudinal administrative claims database.

We queried the MarketScan Commercial Claims and Encounters database to identify patients who had undergone ACDF or laminoplasty for multilevel CSM from 2007 to 2016. The patients were stratified by operation type. Patients aged <18 years, patients with a history of tumor or trauma, and patients who had undergone anteroposterior approach were excluded from the present study.

A total of 5445 patients were included, of whom 1521 had undergone laminoplasty. A matched cohort who had underations and readmissions compared with laminoplasty but was associated with greater costs. Additional prospective research is required to investigate the factors driving the higher costs of ACDF in this population and the long-term clinical outcomes.
