#1
Benlong Shi, Qinghua Zhao, Liang Xu, Zhen Liu, Xu Sun, Zezhang Zhu, Yong Qiu
BACKGROUND: Several osteotomy techniques including pedicle subtraction osteotomy and vertebral column resection have been employed in the correction of congenital kyphosis (CK) and satisfying outcomes have been demonstrated. However, the SRS-Schwab Grade 4 osteotomy, defined as resection of posterior elements, partial vertebral body and superior adjacent disc, is rarely reported in the treatment of CK. PURPOSE: To evaluate the efficiency and safety of SRS-Schwab Grade 4 osteotomy in CK patients, and to propose its optimal indication...

Nikhil Jain, Khaled Himed, Jeffrey M Toth, Karen C Briley, Frank M Phillips, Safdar N Khan
BACKGROUND CONTEXT: Opioid use is prevalent for management of pre- and post-operative pain in patients undergoing spinal fusion. There is evidence that opioids downregulate osteoblasts in-vitro, and one previous study found that morphine delays the maturation and remodeling of callus in a rat femur fracture model. However, the effect of opioids on healing of spinal fusion has not been investigated before. Isolating the effect of opioid exposure in humans would be limited by the numerous confounding factors that affect fusion healing...

Wesley M Durand, J Mason DePasse, Eren O Kuris, JaeWon Yang, Alan H Daniels
BACKGROUND CONTEXT: Unrecognized and inadequately repaired intraoperative durotomies may lead to cerebrospinal fluid leak, pseudomeningocele, and other complications. Few studies have investigated durotomy that is unrecognized intraoperatively and requires additional postoperative management (hereafter, late-presenting dural tear [LPDT]), though estimates of LPDT range from 0.6 - 8.3 per 1,000 spinal surgeries. These single-center studies are based on relatively small sample sizes for an event of this rarity, all with <10 patients experiencing LPDT...

BACKGROUND CONTEXT: The presence of missing data is a limitation of large datasets, including the National Surgical Quality Improvement Program (NSQIP). In addressing this issue, most studies utilize complete case analysis, which excludes cases with missing data, thus potentially introducing selection bias. Multiple imputation, a statistically rigorous approach that approximates missing data and preserves sample size, may be an improvement over complete case analysis. PURPOSE: To evaluate the impact of using multiple imputation in comparison to complete case analysis for assessing the associations between preoperative laboratory values and adverse outcomes following anterior cervical discectomy and fusion (ACDF) procedures...

BACKGROUND: Symptoms of preoperative anxiety and depression occur in approximately one-third of patients with chronic back pain undergoing surgery. In the last 2 decades, several studies have established that preoperative anxiety and depression are important outcome predictors of greater pain and physical impairments, and lower health-related quality of life in patients undergoing spine surgery. To accommodate symptoms of anxiety and depression and thereby better surgical outcomes, we need to identify factors associated with these symptoms...

BACKGROUND CONTEXT: With advances in the understanding of adult spinal deformity (ASD), more complex osteotomy and fusion techniques are being implemented with increasing frequency. Patients undergoing ASD corrections infrequently require extended acute care, longer inpatient stays, and are discharged to supervised care. Given the necessity of value-based health care, identification of clinical indicators for adverse discharge disposition in ASD surgeries is paramount. PURPOSE: On nationwide and surgeon-created databases, identify predictors of adverse discharge disposition after ASD surgeries and view corresponding differences in charges...

B N Shultz, P Bovonratwet, N T Ondeck, T D Ottesen, R P McLynn, J N Grauer
BACKGROUND CONTEXT: The use of national databases in spinal surgery outcomes research is increasing. A number of variables collected by the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) changed between 2010 and 2011, coinciding with a rapid increase in the number of patients included per year. However, there has been limited study evaluating the effect that these changes may have on the results of outcomes studies. PURPOSE: To investigate the influence of changing data elements and growth of the NSQIP database on results of lumbar fusion outcomes studies...

Harald Krenzlin, Ta-Chih Tan, Christina Lampe, Christian Lampe, Markus Knuf, Peter Horn, Manfred Schwarz
BACKGROUND CONTEXT: In patients with Mucopolysaccharidosis (MPS), glycosaminoglycans deposits in the dura mater and supporting ligaments cause spinal cord compression and consecutive myelopathy, predominantly of the cranio-cervical junction. Disease characteristics of cranio-cervical stenosis (CCS) in MPS patients differ profoundly from other hereditary and degenerative forms. Due to high peri-procedural morbidity and mortality, MPS patients pose a substantial challenge to the unexperienced medical care provider...
