A Patient-specific Approach to Alignment and Proximal Junctional Kyphosis Risk Assessment in Adult Spinal Deformity Surgery: Development and Validation of a Predictive Tool.

Study Design: This was a single-institution, retrospective cohort study.

Objective: We aimed to develop a predictive model for proximal junctional kyphosis (PJK) severity that considers multiple preoperative variables and modifiable surgical alignment.

Summary Of Background Data: PJK is a common complication following adult deformity surgery.

When does CT myelography add value beyond MRI for lumbar degenerative disease?

Background Context: In patients with lumbar spinal stenosis, it is crucial for clinicians to identify all symptomatic levels. Prior studies have demonstrated that CT myelography has a greater sensitivity in revealing stenosis (94.4%) compared to MRI (75.

Optimal Trajectory and Length of S2 Alar Iliac Screws: A 3-Dimensional Computed-aided Design Study.

Study Design: A radiographic study of computed tomography scans of the pelvis converted to 3-dimensional imaging.

Objective: The objective of this study was to determine the optimal length and trajectory of S2 alar iliac (S2AI) screws.

Summary Of Background Data: Solid pelvic fixation is a necessary component in thoracolumbar deformity surgery to protect sacral fixation and promote arthrodesis.

Utility of Anxiety/Depression Domain of EQ-5D to Define Psychological Distress in Spine Surgery.

Background: Prospective patient-reported outcomes (PROs) registries are central to emerging evidence-driven reform models. These registries entail significant operator and responder burden to capture PROs data. It is important to limit the number of PROs administered.

Effect of Modified Japanese Orthopedic Association Severity Classifications on Satisfaction With Outcomes 12 Months After Elective Surgery for Cervical Spine Myelopathy.

Study Design: This study retrospectively analyzes prospectively collected data.

Objective: Here, we aim to determine the influence of preoperative and 12-month modified Japanese Orthopedic Association (mJOA) on satisfaction and understand the change in mJOA severity classification after surgical management of degenerative cervical myelopathy (DCM).

Summary Of Background Data: DCM is a progressive degenerative spine disease resulting from cervical cord compression.

Emergency Department Visits After Elective Spine Surgery.

Background: Emergency department (ED) overuse is a costly and often neglected source of postdischarge resource utilization after spine surgery. Failing to investigate drivers of ED visits represents a missed opportunity to improve the value of care in spine patients.

Objective: To identify the prevalence, drivers, and timing of ED visits following elective spine surgery.

Causes and Timing of Unplanned 90-day Readmissions Following Spine Surgery.

Study Design: Retrospective cohort study.

Objective: The aim of this study was to evaluate the causes, timing, and factors associated with unplanned 90-day readmissions following elective spine surgery.

Summary Of Background Data: Unplanned readmissions after spine surgery are costly and an important determinant of the value of care.

Incidence and Radiographic Predictors of Valgus Tibiotalar Tilt After Hindfoot Fusion.

Background: The development of valgus tibiotalar tilt following hindfoot arthrodesis is rarely discussed in the literature. The purpose of this study was to determine the incidence of valgus tibiotalar tilt and to evaluate if there were any radiographic predictors for the development of valgus tibiotalar tilt.

Methods: Patients who underwent hindfoot fusion between January 1, 2004 and December 31, 2013 were identified.

No Incidence of Postoperative Knee Sepsis With Suprapatellar Nailing of Open Tibia Fractures.

Objective: To evaluate the incidence of knee sepsis after suprapatellar (SP) nailing of open tibia fractures.

Design: Retrospective; Setting: ACS level 1 trauma center.

Patients/participants: We reviewed 139 open tibia fractures that underwent SP nailing as definitive treatment over a 5-year period (January 1, 2011 to January 1, 2016).

Injury Rate and Patterns Among CrossFit Athletes.

Background: CrossFit is a type of competitive exercise program that has gained widespread recognition. To date, there have been no studies that have formally examined injury rates among CrossFit participants or factors that may contribute to injury rates.

Purpose: To establish an injury rate among CrossFit participants and to identify trends and associations between injury rates and demographic categories, gym characteristics, and athletic abilities among CrossFit participants.

Articular shear of the anterior-inferior quadrant of the glenoid: a glenolabral articular disruption lesion variant.

Traumatic cartilage lesions of the shoulder, such as glenolabral articular disruption (GLAD), have previously been recognized in patients with shoulder instability. We describe a new lesion in which the entire anteroinferior quadrant of the glenoid articular cartilage is sheared off in association with an adjacent labral tear. Both patients were teenage athletes who were being treated arthroscopically for shoulder instability.

Implications of 25% to 50% coronary stenosis with cardiac computed tomographic angiography in ED patients.

Objective: The aim of this study was to determine if patients presenting with symptoms of acute coronary syndrome and found to have 25% to 50% diameter reduction with coronary computed tomographic angiography (CCTA) are likely to benefit from further diagnostic testing.

Methods: A registry study of 213 subjects (median age, 51 years; 53% women) with symptoms concerning for possible acute coronary syndrome with low-risk features found to have 25% to 50% maximal diameter stenosis on CCTA was performed at 2 academic medical centers. The analysis was approved by an institutional review board and was conducted with waiver of consent.

Young patients with chest pain: 1-year outcomes.

Objective: Prior studies found that young adult chest pain patients without known cardiac disease with either no cardiac risk factors or a normal electrocardiogram (ECG) are at low risk (<1%) for acute coronary syndromes (ACS) and 30-day cardiovascular events. Longer-term event rates in this subset of patients are unknown. We hypothesized that patients younger than 40 years without past cardiac history and a normal ECG are at less than 1% risk for 1-year adverse cardiovascular events.

Relation between thrombolysis in myocardial infarction risk score and one-year outcomes for patients presenting at the emergency department with potential acute coronary syndrome.

The Thrombolysis in Myocardial Infarction (TIMI) score, derived from unstable angina/non-ST-segment elevation acute myocardial infarction patient population, predicts 14-day cardiovascular events. It has been validated in emergency department (ED) patients with potential acute coronary syndrome with respect to 30-day outcomes. Our objective was to determine whether the initial TIMI score could risk stratify ED patients with potential acute coronary syndrome with respect to the 1-year outcomes.
