Purpose: To investigate the average fluoroscopy time, as well as the patient and surgical staff average radiation exposure in the context of intraoperative fluoroscopy use during anterior total hip arthroplasty (THA).

Methods: PubMed, Cochrane, Embase, Web of Science and Scopus were systematically searched for studies pertaining to intraoperative anterior THA fluoroscopy (PROSPERO ID 258049). The comprehensive literary search was conducted using "THA," "fluoroscopy" and "radiation exposure" as the search criteria, which resulted in 187 total papers.

Objective: Cervical deformity (CD) patients have severe disability and poor health status. However, little is known about how patients with rigid CD compare with those with flexible CD. The main objectives of this study were to 1) assess whether patients with rigid CD have worse baseline alignment and therefore require more aggressive surgical corrections and 2) determine whether patients with rigid CD have similar postoperative outcomes as those with flexible CD.

Background: Changes in spinopelvic and lower extremity alignment between standing and relaxed sitting have important clinical implications with regard to stability of total hip arthroplasty. This study aimed to analyze the effect of body mass index (BMI) on lumbopelvic alignment and motion at the hip joint.

Methods: A retrospective review of patients who underwent full-body stereoradiographs in standing and relaxed sitting for total hip arthroplasty planning was conducted.

Hospital-acquired conditions (HACs) have been the focus of recent initiatives by the Centers for Medicare and Medicaid Services in an effort to improve patient safety and outcomes. Spine surgery can be complex and may carry significant comorbidity burden, including so called "never events." The objective was to determine the rates of common HACs that occur within 30-days post-operatively for elective spine surgeries and compare them to other common surgical procedures.

Introduction: Patient reported outcomes measurement information system (PROMIS) is a quality of life metric that has gained increased popularity due to computer adaptive testing. Previous studies have shown that PROMIS correlates with Oswestry Disability Index (ODI) in patients with back pain and takes significantly less time to complete. However, the ability of PROMIS to capture disability from spinal malalignment relative to established metrics is unknown.

Study Design: Retrospective cohort study.

Objective: To investigate radiological differences in lumbar disc herniations (herniated nucleus pulposus [HNP]) between patients receiving microscopic lumbar discectomy (MLD) and nonoperative patients.

Methods: Patients with primary treatment for an HNP at a single academic institution between November 2012 to March 2017 were divided into MLD and nonoperative treatment groups.

Study Design: Retrospective review from a single institution.

Objective: To investigate the effect of hip osteoarthritis (OA) on spinopelvic compensatory mechanisms as a result of reduced hip range of motion (ROM) between sitting and standing.

Summary Of Background Data: Hip OA results in reduced hip ROM and contracture, causing pain during postural changes.

Study Design: Single institution retrospective clinical review.

Objective: To investigate the relationship between levels fused and clinical outcomes in patients undergoing open and minimally invasive surgical (MIS) lumbar fusion.

Summary Of Background Data: Minimally invasive spinal fusion aims to reduce the morbidity associated with conventional open surgery.

Background: Regional and segmental changes of the lumbar spine have previously been described as patients transition from standing to sitting; however, alignment changes in the cervical and thoracic spine have yet to be investigated. So, the aim of this study was to assess cervical and thoracic regional and segmental changes in patients with thoracolumbar deformity versus a nondeformed thoracolumbar spine population.

Methods: This study was a retrospective cohort study of a single center's database of full-body stereoradiographic imaging and clinical data.

Study Design: Single-center retrospective study.

Objective: Investigate how differing degrees of pelvic incidence (PI) modulate the recruitment of pelvic tilt (PT) in response to similar amounts of sagittal malalignment as measured by T1-Pelvic Angle (TPA).

Summary Of Background Data: Past research has shown that some patients do not recruit PT in response to sagittal malalignment.

Background: Proximal junctional kyphosis (PJK) is a common radiographic complication of adult spinal deformity (ASD) corrective surgery. Although previous literature has reported a 5 to 61% incidence of PJK, these studies are limited by small sample sizes and short-term follow-up.

Objective: To assess the incidence of PJK utilizing a high-powered ASD database.

Study Design: Retrospective cohort study.

Objective: To evaluate the ability of patient reported outcome measurement information system (PROMIS) assessments to capture disability related to cervical sagittal alignment and secondarily to compare these findings to legacy outcome measures.

Summary Of Background Data: PROMIS is a validated patient-reported outcome metric that is increasing in popularity due to its speed of administration relative to legacy metrics.

Objective: The Patient-Reported Outcomes Measurement Information System (PROMIS) has become increasingly popular due to computer adaptive testing methodology. This study aims to validate the association between PROMIS and legacy outcome metrics and compare PROMIS to legacy metrics in terms of ceiling and floor effects and questionnaire burden.

Methods: A retrospective review of an outcomes database was performed at a single institution from December 2016 to April 2017.

This study sought to assess comorbidity profiles unique to early-onset-scoliosis (EOS) patients by employing cluster analytics and to determine the influence of isolated comorbidity clusters on perioperative complications, morbidity and mortality using a high powered administrative database. The KID database was queried for ICD-9 codes pertaining to congenital and idiopathic scoliosis from 2003, 2006, 2009, 2012. Patients <10 y/o (EOS group) were included.

Background Context: Lumbar disc herniation and retrolisthesis have been shown to be significant degenerative changes that can be associated with back pain. Current literature has shown evidence that retrolisthesis is associated with similar baseline function in patients with L5-S1 disc herniation, but worse postoperative outcomes 2 years after lumbar discectomy. However, literature comparing long-term postoperative outcomes at 8-year follow-up in patients with L5-S1 disc herniation with retrolisthesis is lacking.

Background: Bariatric surgery (BS) is an increasingly common treatment for morbid obesity that has the potential to effect bone and mineral metabolism. The effect of prior BS on spine surgery outcomes has not been well established. The aim of this study was to assess differences in complication rates following spinal surgery for patients with and without a history of BS.

Unlabelled: The objective of this study was to analyze if the addition of CT changed the management of femoral shaft fractures caused by gunshot wounds when compared to those managed with plain radiography alone.

Methods: A multiple-choice, single-answer electronic survey was created to compare utility of advanced imaging when treating femur fractures resulting from gunshot injury. A total of ten femoral shaft fracture cause by gunshot injuries were selected for an online survey to be administered to orthopeaedic traumatologists.
