Risk Factors for Sacroiliac Joint Fusion after Instrumented Spinal Fusion.

Study Design: Retrospective Cohort Study.

Objective: To identify risk factors for sacroiliac (SI) joint fusion after instrumented spinal fusion.

Methods: Patients were identified from the PearlDiver BiscayneBay database.

Utilization of Vertebroplasty/Kyphoplasty in the Management of Compression Fractures: National Trends and Predictors of Vertebroplasty/Kyphoplasty.

Objective: The purpose of this study is to examine the utilization of kyphoplasty/vertebroplasty procedures in the management of compression fractures. With the growing elderly population and the associated increase in rates of osteoporosis, vertebral compression fractures have become a daily encounter for spine surgeons. However, there remains a lack of consensus on the optimal management of this patient population.

Characterizing utilization patterns and reoperation risk factors of interspinous process devices: analysis of a national claims database.

Introduction: Interspinous process devices (IPDs) were developed as minimally invasive alternatives to open decompression surgery for spinal stenosis. However, given high treatment failure and reoperation rates, there has been minimal adoption by spine surgeons. This study leveraged a national claims database to characterize national IPD usage patterns and postoperative outcomes after IPD implantation.

Risk Factors for Radiotherapy Failure in the Treatment of Spinal Metastases.

Study Design: Retrospective cohort study.

Objective: To build a predictive model for risk factors for failure of radiation therapy, hypothesizing a higher SINS would correlate with failure.

Methods: Patients with spinal metastasis being treated with radiation at a tertiary care academic center between September 2014 and October 2018 were identified.

Surgery on the Day of Admission Decreases Postoperative Complication Rates for Patients With Central Cord Syndrome: An Analysis of National Surgical Quality Improvement (NSQIP) Data From 2010 to 2020.

Study Design: Retrospective review.

Objective: This study was undertaken to determine what constitutes "early optimal timing" of surgical management of central cord syndrome (CCS) with respect to a reduction of medical complications.

Summary Of Background Data: Data varies on the optimal time for surgical treatment of CCS with some studies favoring early intervention and others advocating that surgery can or should be delayed for 2-6 weeks.

Surgical Management of Type II Displaced Dens Fractures Improves One-year Mortality in Elderly Patients.

Study Design: Retrospective cross-sectional analysis of US national data collected by PearlDiver Inc. database.

Objective: To determine the rates of surgical/nonsurgical treatments and associated one-year mortality for displaced type II dens fractures without neurological deficit.

Proximal Junctional Kyphosis: Inter- and Intraobserver Reliability of Radiographic Measurements in Adult Spinal Deformity.

Study Design: Reliability study of radiographic measures of proximal junctional kyphosis (PJK) in patients with adult spinal deformity (ASD).

Objective: To assess impacts of level of proximal endpoint and vertebral fracture on reliability of measurement of junctional kyphosis.

Summary Of Background Data: Radiographic assessment is important in determining management of patients with PJK or proximal junctional failure (PJF).

Differentiation of Murine Bone Marrow-Derived Smooth Muscle Progenitor Cells Is Regulated by PDGF-BB and Collagen.

Smooth muscle cells (SMCs) are key regulators of vascular disease and circulating smooth muscle progenitor cells may play important roles in vascular repair or remodelling. We developed enhanced protocols to derive smooth muscle progenitors from murine bone marrow and tested whether factors that are increased in atherosclerotic plaques, namely platelet-derived growth factor-BB (PDGF-BB) and monomeric collagen, can influence the smooth muscle specific differentiation, proliferation, and survival of mouse bone marrow-derived progenitor cells. During a 21 day period of culture, bone marrow cells underwent a marked increase in expression of the SMC markers α-SMA (1.

Intrathoracic Glenohumeral Dislocation without Fracture of the Humerus: A Case Report and Review of the Literature.

Case: A fifty-three-year-old man presented with an intrathoracic glenohumeral dislocation (ITGHD) and associated hemothorax, rib fracture, massive rotator cuff tear, and axillary nerve palsy following an ice hockey injury. Treatment consisted of closed reduction and staged open rotator cuff repair. Despite a substantial injury, the patient recovered nearly normal use of the arm two years postoperatively.
