Cystathionine-β-synthase (CBS) deficiency is a human genetic disease causing homocystinuria, thrombosis, mental retardation, and a suite of other devastating manifestations. Early detection coupled with dietary modification greatly reduces pathology, but the response to treatment differs with the allele of CBS. A better understanding of the relationship(More)
BACKGROUND CONTEXT Spine surgeons employ a high volume of imaging in the diagnosis and evaluation of spinal pathology. However, little is known regarding patients' knowledge of the radiation exposure associated with these imaging techniques. PURPOSE To characterize spine patients' knowledge regarding radiation exposure from various imaging modalities. (More)
BACKGROUND CONTEXT Lateral lumbar interbody fusion (LLIF) is a frequently used technique for the treatment of lumbar pathology. Despite its overall success, LLIF has been associated with a unique set of complications. However, there has been inconsistent evidence regarding the complication rate of this approach. PURPOSE To perform a systematic review(More)
STUDY DESIGN Retrospective cohort study. OBJECTIVE To determine if an association exists between body mass index (BMI) and the rate of revision surgery after single-level minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). SUMMARY OF BACKGROUND DATA MIS TLIF is an effective treatment for lumbar degenerative disease. Previous studies in(More)
STUDY DESIGN This is a retrospective cohort study. OBJECTIVE To determine if preoperative mental health is associated with patient-reported outcomes (PROs) following a minimally invasive lumbar discectomy. SUMMARY OF BACKGROUND DATA PROs are commonly used to quantify a patient's perceived health status. Recently, mental health has been theorized to(More)
STUDY DESIGN Retrospective imaging review. OBJECTIVE Utilize magnetic resonance imaging (MRI) to expand the anatomical description of psoas morphology and its association with neurovascular structures at L4-5. SUMMARY OF BACKGROUND DATA Anatomical psoas muscle variants may present a greater risk of neurovascular injury at the L4-5 level during lateral(More)
MINI: The publication rate of conference abstract presentations as full-length manuscripts is a potential measure of meeting quality. 43.8% of abstracts presented at the 2010-2012 North American Spine Society annual meetings were published as full-length manuscripts within 3 years. Podium presentations and "Best" or "Outstanding" paper presentations were(More)
PURPOSE OF REVIEW The purpose of this study is to summarize the recent literature investigating the use of minimally invasive (MIS) techniques in the treatment of lumbar degenerative stenosis, spondylolisthesis, and scoliosis. RECENT FINDINGS MIS lumbar decompression and fusion techniques for degenerative pathology are associated with reduced operative(More)
Typical sources for graft material utilized in minimally invasive transforaminal lumbar interbody fusion include both autograft and allograft. Autograft is frequently utilized due to its theorized benefits in promoting fusion. During minimally invasive transforaminal lumbar interbody fusion, autograft is often obtained locally during the laminectomy and(More)
STUDY DESIGN A retrospective analysis. OBJECTIVE The aim of this study was to quantify improvements in Visual Analogue Scale (VAS) neck and arm pain, Neck Disability Index (NDI), and Short Form-12 (SF-12) Mental (MCS) and Physical (PCS) Composite scores following an anterior cervical discectomy and fusion (ACDF). SUMMARY OF BACKGROUND DATA ACDF is(More)
