LLIF appears to be especially effective when the lumbar lordosis and sagittal balance correction goals are less than 10° and 5 cm, respectively. However, the review demonstrated a lack of consistent reporting on sagittal balance restoration with the MIS LLIF techniques.

Our data confirm proposed potential benefits attributable to the minimally invasive nature of pEVAR while demonstrating cost-effectiveness despite the additional cost of closure devices. Taking into account pEVAR failures still does not increase pEVAR costs over cEVAR. Further considering reduced postoperative pain and wound complications, the technique deserves consideration in suitable patients.

Total sacrectomy is associated with compromising important motor, bladder, bowel, sensitivity, and sexual function. Residual motor function is dependent on sparing L5 and S1 nerve roots. Bladder and bowel function is consistently compromised in higher sacrectomies; nevertheless, the probability of maintaining sufficient function increases progressively with the roots spared, especially when S3 nerve roots are spared. Unilateral resection is usually associated with more normal function. To the best of our knowledge, this is the first comprehensive literature review to analyze published reports of residual sacral nerve root function after sacrectomy.

BACKGROUND The border between the United States (US) and Mexico is an international boundary spanning 3000 km, where unauthorized crossings occur regularly. We examine patterns of neurotrauma, health care utilization, and financial costs at our level 1 trauma center incurred by patients from wall-jumping into the US. OBJECTIVE To determine the clinical and socioeconomic consequences from neurotrauma as a result of jumping over the US–Mexico border wall. METHODS Medical records of patients at (Banner University of Arizona Medical Center - Tucson) were retrospectively reviewed from January 2012 through December 2017. Demographics, clinical status, radiographic findings, treatment, length of stay, and financial data were analyzed for all patients suffering neurotrauma during that time. RESULTS Over 6 yr, 64 patients sustained cranial or spinal injuries directly from jumping or falling onto US soil from the border wall. Fifty (78%) suffered spinal injuries, 15 (23%) experienced cranial injury, and 1 patient had both. Total medical charges were available in 36 patients and summed $3.6 M, of which 22% was reimbursed, an amount significantly lower than expected from more conventional trauma. Neurotrauma steadily declined over the 6-yr observation period, dropping in 2017 to 6% of rates observed in 2012. CONCLUSION In the Southern US, neurotrauma from unauthorized border crossings occurs commonly as a result of wall-jumping. These injuries represent a clinical and costly extreme of border-related trauma, and future efforts from both sides of the border wall are needed to decrease the detrimental impacts felt both by immigrants and surrounding health care systems.

The mTS is suggestive of actual survival for patients with a good prognosis. It is less accurate for patients with an estimated survival of less than 12 months. The decreasing trend in mTS accuracy over time will likely further reduce mTS utility. An important opportunity exists to develop new instruments to assist spine surgeons and oncologists to choose appropriate surgical or non-surgical treatment modalities for patients with metastatic spine disease.
