Cervical facet injuries, though less common than other spinal injuries, represent a subset of subaxial cervical spine injuries and can present significant challenges in terms of diagnosis, management, and outcomes. A major concern with cervical facet fracture is identifying instability patterns that may necessitate surgical stabilization. Particularly in cases of cervical facet fracture dislocations, there remains controversy regarding requirements for closed reduction, timing, surgical approach, need for preoperative MRI, and method of fixation.

Objective: The aim of this study was to analyze the trend in hospital charge and payment adjusted to corresponding surgeon charge and payment for cervical and lumbar fusions in a Medicare sample population from 2005 to 2014.
Summary Of Background Data: Previous studies have reported trends and variation in hospital charges and payments for spinal fusion, but none have incorporated surgeon data in analysis.
Study Design: Retrospective database review.
Objective: To understand medical complication rates, readmission rates, costs, and discharge dispositions in anterior lumbar interbody fusion (ALIFs) versus transforaminal lumbar interbody fusions (TLIFs)/posterior lumbar interbody fusions (PLIFs) for lumbar degenerative disease.
Summary Of Background Data: Indications for ALIFs versus PLIFs can vary, though benefits of anterior approach surgery include full access to the anterior column and ability to place fusion devices.
Study Design: A cadaveric study.
Summary Of Background Data: Translaminar screws were initially developed for C2 fixation. Since then, their usage has expanded to include the subaxial cervical spine, and thoracic and lumbar spine.
Spinal subdural abscess is a rare central nervous system infection with just over a hundred cases reported. It is much less common than spinal epidural abscess. While most case reports have focused on route of infection and treatment options, there have not been any reports that focused on the unique MRI findings of spinal subdural abscess.

Retrospective studies may underreport neurological deficits due to selection, detection, and recall biases. Prospective studies are expensive and more difficult to perform, but they likely provide more accurate estimates of new neurological deficit rates.

Objective: To study postoperative complication rates following thoracolumbar fusion for traumatic thoracolumbar fracture in patients with ankylosing spondylitis (AS) compared with patients without AS.
Methods: The PearlDiver database (2005 to 2012) was queried to examine postoperative complication rates in patients with AS undergoing posterior thoracolumbar fusion for thoracolumbar fracture ( = 968).
Study Design: A retrospective database review.
Objective: The aim of this study was to determine the complication and mortality rates in patients 80 years of age and older who were treated with anterior cervical fusion surgery and to compare these rates against those of other elderly patients.
Summary Of Background Data: Cervical spondylosis is frequently observed in the elderly and is the most common cause of myelopathy in older adults.
Background Context: Although multiple studies have cited that diabetes mellitus as a risk factor decreased functional outcomes, increased infectious complications, and overall increased reoperation rate following degenerative lumbar spinal surgery, few have investigated how perioperative glycemic control influences such complications.
Purpose: The primary goal of the present study was to use a national database to evaluate the association of perioperative glycemic control as demonstrated by hemoglobin A1c (HbA1c) levels in patients with diabetes undergoing primary, single-level decompression without concomitant fusion with the incidence of deep postoperative infection requiring operative irrigation and debridement. Our secondary objective was to calculate a threshold level of HbA1c above which the risk of postoperative infection after lumbar decompression increases significantly in patients with diabetes.
OBJECTIVE Lumbar epidural steroid injections (LESIs) are performed for both diagnostic and therapeutic purposes for a variety of indications, including low-back pain, the leading cause of disability and expense due to work-related conditions in the US. The steroid agent used in epidural injections is reported to relieve nerve root inflammation, local ischemia, and resultant pain, but the injection may also have an adverse impact on spinal surgery performed thereafter. In particular, the possibility that preoperative epidural injections may increase the risk of surgical site infection after lumbar spinal fusion has been reported but has not been studied in detail.
View Article and Find Full Text PDFObjective: To evaluate the association of perioperative hemoglobin A (HbA) level in patients with diabetes with the incidence of infection after anterior cervical discectomy and fusion requiring operative intervention, in addition to determining if a threshold level of HbA above which the risk of infection increases significantly exists.
Methods: A national administrative database was queried for patients who underwent primary anterior cervical discectomy and fusion with diabetes who had a perioperative HbA level recorded within 3 months of surgery. These patients were stratified based on their HbA level in 0.
Study Design: A retrospective database analysis.
Objective: The aim of this study was to determine whether any association exists between preoperative cervical epidural steroid injections (CESIs) at various time intervals before anterior cervical discectomy and fusion (ACDF) or posterior cervical fusion (PCF) and the incidence of postoperative infection.
Summary Of Background Data: Although infectious complications following CESI are uncommon, the association between preoperative CESI and postoperative infection following ACDF or PCF has yet to be evaluated in the current literature.
Study Design: Retrospective database review.
Objective Of The Study: The objective of the study was to assess whether bone morphogenetic protein (BMP) decreases the risk of revision surgery in elderly patients treated with 3-7 level or 8 or greater level fusions.
Summary Of Background Data: Revision spine surgery in the elderly is a complex undertaking, highlighting the importance of discovering methods to decrease the risk of repeat procedures.
Background: Telephone calls play a significant role in the follow-up care of postoperative patients. However, further data are needed to identify the determinants of patient-initiated telephone calls after surgery because these factors may also highlight potential areas of improvement in patient satisfaction and during the hospital discharge process. Therefore, the goal of this study is to determine the number of postoperative patient telephone calls within 14 days after surgery and establish the factors associated with patient-initiated calls and reasons for calling.
