STUDY DESIGN: Double-blinded, prospective laboratory animal study. OBJECTIVE: To examine if intraoperative spinal cord stimulation (SCS) inhibits the development of spine surgery-induced hypersensitivity. SUMMARY OF BACKGROUND DATA: Managing postoperative pain after spine surgery is challenging, and as many as 40% of patients may develop failed back surgery syndrome (FBSS). While SCS has been shown to effectively reduce chronic pain symptoms, it is unknown if intraoperative SCS can mitigate the development of central sensitization that potentially leads to FBSS after spine surgery...

STUDY DESIGN: Retrospective radiographic analysis. OBJECTIVES: Evaluation of the anatomical features of the craniovertebral junction in patients with occipitalization with and without atlantoaxial dislocation (AAD). SUMMARY OF BACKGROUND DATA: Atlas occipitalization is a common feature of congenital AAD and usually requires surgical intervention. However, not all instances of occipitalization necessarily lead to AAD. No study has specifically examined and compared the craniovertebral bony morphology in occipitalization with, and without, AAD...

STUDY DESIGN: Retrospective review of prospectively collected multi-surgeon data. OBJECTIVE: Examine the rate, clinical impact, predictors of subsidence after expandable MI-TLIF cage. SUMMARY OF BACKGROUND DATA: Expandable cage technology has been adopted in minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) to reduce the risks and optimize outcomes. Although subsidence is of particular concern when using expandable technology as force required to expand the cage can weaken the endplates, its rates, predictors, and outcomes lack evidence...

STUDY DESIGN: Retrospective, nonblinded, single center observational study. OBJECTIVE: Examine associations between small vertebral neural canal (VNC) measurements with verified indicators of early-life stress [ELS] (premature birth, disorders or conditions arising in the perinatal period, and congenital disorders) in a pediatric autopsy sample, paired with other skeletal indicators of stress, and known demographic/health information. SUMMARY OF BACKGROUND DATA: Most studies linking small VNC size to ELS are for human remains from archaeological sites without known demographic information or health history, making it difficult to assess what kind of stress might affect VNC growth...

STUDY DESIGN: Meta-analysis. OBJECTIVE: To determine the single nucleotide polymorphisms that are related to adult idiopathic scoliosis. SUMMARY AND BACKGROUND DATA: Adolescent Idiopathic Scoliosis (AIS) is considered one of the most prevalent spinal diseases. Even though the cause of AIS is yet to be determined, family history and gender have shown conclusive associations. Multiple studies have indicated that AIS is more prevalent in families where at least one other first-degree relative is similarly affected, indicating a possible genetic etiology to AIS...
