BACKGROUND: Surgical site infection (SSI) following spine surgery is associated with increased morbidity, reoperation rates, hospital readmissions and cost. The incidence of SSI following posterior cervical spine surgery is higher than anterior cervical spine surgery, with rates from 4.5-18%. It is well documented that higher body mass index (BMI) is associated with increased risk of SSI after spine surgery. There are only a few studies that examine the correlation of BMI and SSI after posterior cervical instrumented fusion (PCIF) using national databases, however, none that compare trauma and non-traumatic patients...

BACKGROUND CONTEXT: The STarT Back Screening Tool (SBST) categorizes risk of future disability in patients with low back pain (LBP). Previous studies evaluating the use of SBST in physical therapy populations do not reflect the ethnic and socioeconomic diversity occurring in clinical practice and lack statistical power to evaluate factors associated with outcomes within each SBST risk category. PURPOSE: The purpose of this study is to further refine SBST risk categorization for predicting improvements in functional disability with attention towards patient level factors that might guide SBST use in routine outpatient physical therapy practice...

Backgound Context: Abnormal proximal femoral angle (PFA) was recently found to be associated with deteriorating sagittal balance and quality of life (QoL) in high-grade spondylolisthesis (HGS). However, the influence of PFA on the QoL of patients undergoing surgery remains unknown. PURPOSE: This study compares the pre- and postoperative measurements of sagittal balance including PFA in patients with lumbosacral HGS after surgery. It also determines if PFA is a radiographic parameter that is associated with QoL in patients undergoing surgery...

BACKGROUND: In modern clinical research, the accepted minimum follow-up for patient-reported outcome measures (PROMs) after lumbar spine surgery is 24 months, particularly after fusion. Recently, this minimum requirement has been called into question. PURPOSE: We aim to quantify the concordance of 1- and 2-year PROMs to evaluate the importance of long-term follow-up after elective lumbar spine surgery. STUDY DESIGN: Retrospective analysis of data from a prospective registry...

BACKGROUND CONTEXT: Previous studies have found an association between mental illness and poor outcomes in spine surgery, but little is known about the effects of depression and/or anxiety on the adult spinal deformity population. In addition, most relevant studies exclusively focused on the lumbar spine and had relatively small patient sizes. PURPOSE: The aim of this study was to investigate whether adult spinal deformity patients with depression and/or anxiety have an increased risk of postoperative complications and reoperation following posterior thoracolumbar spinal surgery...

BACKGROUND: The optimal method for surgical treatment of early onset scoliosis is currently unknown. Although the aim of growth-friendly systems is to reduce the curve and maintain growth, there is no consensus on how to measure spinal growth during and after the treatment. Different measurements of different segments (T1-S1, T1-T12, instrumented length) are used for different time points to evaluate growth. The aim of this review is to assess what measurements are used and to compare the growth-friendly systems based on spinal growth during treatment...

BACKGROUND CONTEXT: Bone marrow-derived mesenchymal stem cells (BMSCs) and periosteum-derived cells (PDCs) have shown great viability in terms of osteogenic potential and have been considered the major cellular source for skeletal tissue engineering. Using a PDCs-impregnated cell sheet to surround a BMSCs-impregnated tricalcium phosphate (TCP) scaffold might create a periosteum-bone biomimetic bone graft substitute to enhance spine fusion. PURPOSE: The purpose of this study was to determine the feasibility of using this newly tissue-engineered biomimetic bone graft for posterolateral spine fusion...

BACKGROUND CONTEXT: Underlying cognitive factors have been found to influence patients' symptom experience. Current evidence suggests that concomitant changes in appraisal must be taken into account to accurately interpret change as measured by standard spine patient-reported outcomes (PROs). PURPOSE: To investigate changes in patients' minimally important differences (MID) over recovery from spinal surgery; whether and how cognitive appraisal processes are implicated in the change trajectories...

BACKGROUND: Carotid artery injury and stroke secondary to prolonged retraction remains an extremely rare complication in anterior cervical discectomy and fusion (ACDF). However, multiple studies have demonstrated that carotid artery retraction during the surgical approach may alter the normal blood flow, leading to a significant reduction in the cross-sectional area of the vessel. Others have suggested that dislodgment of atherosclerotic plaques following manipulation of the carotid artery can be a potential risk for intracranial embolus and stroke...

BACKGROUND CONTEXT: Prescription opioid abuse is a public health emergency. Opioid prescriptions for spine patients account for a large proportion of use. Some states have implemented statutory limits on prescribers, however it remains unclear whether such laws are effective. PURPOSE: This investigation compares opioid prescription patterns for patients undergoing lumbar spine surgery before and after the passage of statewide narcotic-limiting legislation in Rhode Island...

BACKGROUND CONTEXT: Posterior lumbar fusion (PLF) is a commonly performed procedure. The evolution of bundled payment plans is beginning to require physicians to more closely consider patient outcomes up to 90 days after an operation. Current quality metrics and other databases often consider only 30 postoperative days. The relatively new Healthcare Cost and Utilization Project National Readmissions Database (HCUP-NRD) tracks patient-linked hospital admissions data for up to one calendar year...

Genevieve Hill, Srinidhi Nagaraja, Austin Bridges, Ardalan Seyed Vosoughi, Vijay K Goel, Maureen L Dreher
BACKGROUND: Growing rod constructs are an important contribution in the treatment of children with early onset scoliosis even though these devices experience high rates of rod fracture. The mechanical performance of traditional, distraction-based dual growing rod constructs is not well understood, and mechanical models for predicting device performance are limited. PURPOSE: Two mechanical models were developed and used to determine the mechanical performance of various growing rod configurations by increasing construct complexity...

BACKGROUND CONTEXT: Adjacent segment disease (ASD) is a well-known complication after lumbar fusion. Lumbar lateral interbody fusion (LLIF) may provide an alternative method of treatment for ASD while avoiding the morbidity associated with revision surgery through a traditional posterior approach. This is the first biomechanical study to evaluate the stability of lateral-based constructs for treating ASD in existing multilevel fusion model. PURPOSE: We aimed to evaluate the biomechanical stability of anterior column reconstruction through the less invasive lateral-based interbody techniques compared to traditional posterior spinal fusion for the treatment of ASD in existing multilevel fusion...

BACKGROUND CONTEXT: Anterior cervical discectomy and fusion (ACDF) without and with cervical plating (ACDF+CP) are accepted surgical techniques for the treatment of degenerative cervical disc disorders. The effect of CP on the development of adjacent segment degeneration (ASD) remains unclear. PURPOSE: To assess whether CP accelerates the degeneration of the adjacent and adjoining segments. STUDY DESIGN / SETTING: This is an imaging cohort study...

BACKGROUND CONTEXT: Models for predicting recovery in traumatic spinal cord injury (tSCI) patients have been developed to optimize care. Several models predicting tSCI recovery have been previously validated, yet recent findings question their accuracy, particularly in patients whose prognoses are the least predictable. PURPOSE: To compare independent ambulatory outcomes in AIS (ASIA [American Spinal Injury Association] Impairment Scale) A, B, C, and D patients, as well as in AIS B+C and AIS A+D patients by applying two existing logistic regression prediction models...

Nurul Haiza Sapiee, Ashvin Thambyah, Peter A Robertson, Neil D Broom
BACKGROUND CONTEXT: The cartilaginous and bony material that can be present in herniated tissue suggests that failure can involve both cartilaginous and vertebral-endplates. How structural integration is achieved across the junction between these two distinct tissue regions via its fibril and mineral components is clearly relevant to the modes of endplate failure that occur. PURPOSE: To understand how structural integration is achieved across the cartilage-vertebral endplate junction...
