Traditional open approaches to correct lumbar spine deformities include 3-column osteotomies, such as a pedicle subtraction osteotomy (PSO). Minimally invasive surgical (MIS) techniques have been developed for lateral transpsoas anterior column realignment (ACR). These 2 techniques have not previously been combined. Our objective was to investigate the cadaveric feasibility of a combined hybrid MIS ACR-PSO technique for deformity correction and to review early clinical experience. ⋯ Our early experience suggests that a combined ACR-PSO with posterior fixation allows for significant correction of segmental lordosis and global imbalance. This combined approach may maximize results attainable with hybrid MIS-open surgical techniques and represents a complementary option to PSO and other posterior approaches.

Observational Study
Regional Variation in Opioid Use After Lumbar Spine Surgery.
The aim of this study was to investigate regional variations in use of opioids after lumbar decompression and fusion surgery for patients with symptomatic lumbar stenosis or spondylolisthesis. ⋯ Our study suggests that regional variations may exist in the use of opioids after lumbar decompression and fusion surgery for patients with symptomatic lumbar stenosis or spondylolisthesis.

Coagulation is an important aspect of the vascular microenvironment in which brain tumors evolve. Patients with tumor often show aberrant coagulation and fibrinolysis activation. In particular, glioblastoma (GBM), the most aggressive primary brain tumor, is associated with a state of hypercoagulability, and venous thromboembolism is a common complication of this cancer and its treatment. Our study aims to investigate the clinical and prognostic significance of routine laboratory tests to assess the coagulative state of patients with brain tumors, to identify potential new prognostic factors and targets for personalized therapy. ⋯ Our data support the assumption that patients with GBM show a plasma hypercoagulable profile and that coagulation profile is related to adverse outcome in patients with GBM. If confirmed, hypercoagulability could play an important role as a prognostic factor of the disease and in the decision of an antithrombotic prophylaxis.

Traumatic brain injury (TBI) has been reported as a risk factor for the development of brain tumors. However, whether TBI affects systemic cancer remains to be determined. We investigated the incidence and factors associated with cancer development in patients with TBI. ⋯ TBI is a risk factor for cancer development, especially in males and those aged <55 years. We hope this information will remind physicians to consider the long-term effects of TBI on cancer development.

Several outcome prediction systems have been developed to evaluate aneurysmal subarachnoid hemorrhage (aSAH). However, they can be difficult to use and can contain subjective elements. We sought to identify the predictors of aSAH outcomes at discharge to provide an accurate and reliable scoring system. ⋯ We propose a grading scale to predict discharge mortality and functional outcomes in patients with aSAH. The proposed scale outperformed most other outcome prediction scales. The proposed scale contains objective elements, is easy to apply by memory, and can be a useful and effective measure to predict aSAH outcomes.
