The 5-Item Modified Frailty Index as a Predictor of Postoperative Outcomes in Thoracic Metastatic Epidural Spinal Cord Compression.

Background: Patients with thoracic metastatic epidural spinal cord compression (MESCC) often undergo extensive surgical decompression to avoid functional decline. Though limited in scope, scales including the revised cardiac risk index (RCRI) are used to stratify surgical risk to predict perioperative morbidity. This study uses the 5-item modified frailty index (mFI-5) to predict outcomes following transpedicular decompression/fusion for high-grade MESCC.

Indication as a predictor for outcomes in anterior cervical discectomy and fusion: The impact of myelopathy on disposition.

Background: While the indication for Anterior Cervical Discectomy and Fusion (ACDF) may influence the expected postoperative course, there is limited data comparing how length of stay (LOS) and disposition for patients with myelopathy differ from those with radiculopathy. This study aimed to compare LOS and discharge disposition, in patients undergoing ACDF for cervical radiculopathy versus those for myelopathy.

Methods: A retrospective review of all adult ACDF cases between 2013 and 2019 was conducted analyzing sex, age, race, comorbidities, level of surgery, myelopathy measures when applicable, complications, dysphagia, hospital LOS, and discharge disposition.

Abnormal L5-S1 Facet Joint Orientation as a Harbinger of Degenerative Spondylolisthesis: A Case Report.

Degenerative spondylolisthesis is a common cause of low back pain and resultant disability in the adult population. The causes of degenerative spondylolisthesis are not entirely understood, though a combination of anatomic and lifestyle factors likely contributes to the development of this pathology. Here, we report a case of a 38-year-old female presenting with low back pain and right lower extremity radiculopathy, found to have degenerative L5-S1 spondylolisthesis, which we postulate developed in part due to the sagittal orientation of her L5-S1 facet joints bilaterally.

Impact of anemia on acute ischemic stroke outcomes: A systematic review of the literature.

Introduction: Anemia has been reported in nearly 40% of acute ischemic stroke (AIS) patients and is linked to significant morbidity and disability. The presence of anemia is associated with worse outcomes in AIS, specifically in the presence of large vessel occlusion (LVO). An optimal hemoglobin (Hb) target specific to this pathology has not yet been established.

Spine centers of excellence: a systematic review and single-institution description of a spine center of excellence.

Background: Centers of excellence (COEs) are interdisciplinary healthcare organizations created with the goal of improving health/economic outcomes in medical treatment for both individuals and health systems, compared to traditionally structured counterparts. Multiple studies have highlighted both societal/individual burdens associated with back pain, underscoring the importance of identifying new avenues for improving both cost/clinical outcomes for this patient population. Here, we utilize available literature to better characterize the features of a spine COE at a tertiary care center and determine the impact of COEs on patient satisfaction and outcomes.

Posterior-only approach for the treatment of symptomatic central thoracic disc herniation regardless of calcification: A consecutive case series of 30 cases over five years.

Purpose: To report the safety and efficacy of posterolateral approach for thoracic disc herniation (TDH) via a consecutive clinical case series of 30 central thoracic disc herniations that were all operated through a posterolateral approach.

Methods: A retrospective review was conducted of all patients with symptomatic TDH who underwent surgical intervention from 2016 to 2021. A total of 23 patients comprising 30 central TDH were included in the study.

The Barrow Biomimetic Spine: Face, Content, and Construct Validity of a 3D-Printed Spine Model for Freehand and Minimally Invasive Pedicle Screw Insertion.

Study Design: Description and evaluation of a novel surgical training platform.

Objectives: The purpose of this study was to investigate the face, content, and construct validity of 5 novel surgical training models that simulate freehand and percutaneous (minimally invasive surgery [MIS]) pedicle screw placement.

Methods: Five spine models were developed by residents: 3 for freehand pedicle screw training (models A-C) and 2 for MIS pedicle screw training (models D and E).

Continuous Activity Tracking Using a Wrist-Mounted Device in Adult Spinal Deformity: A Proof of Concept Study.

Background: Sagittal imbalance in adult spinal deformity (ASD) likely influences balance and ambulatory capacity because of muscular demand, pain, and disability. Disability measures for ASD rely heavily on ambulatory function; however, current metrics may fail to fully capture its contribution. We sought 1) to determine the utility of continuous remote step count monitoring and activity tracking in ASD using a consumer-friendly accelerometer, and 2) to investigate trends and patterns both before and after surgical intervention.

Impact of Lymphangiogenesis on Cardiac Remodeling After Ischemia and Reperfusion Injury.

Background Lymphatic vessels interconnect with blood vessels to form an elaborate system that aids in the control of tissue pressure and edema formation. Although the lymphatic system has been known to exist in a heart, little is known about the role the cardiac lymphatic system plays in the development of heart failure. Methods and Results Mice (C57 BL /6J, male, 8 to 12 weeks of age) were subjected to either myocardial ischemia or myocardial ischemia and reperfusion for up to 28 days.
