Relationship between posterior paraspinal muscle fat infiltration and early conversion to lumbar spinal fusion following decompression surgery.

Purpose: Spinal stenosis, a common degenerative condition causing back pain and neurogenic claudication, often requires decompression surgery when conservative treatments fail. This study investigates the relationship between posterior paraspinal muscle (PPM) measurements and early conversion to lumbar fusion in patients following decompression surgery. Understanding this relationship is crucial, as prior research suggests paraspinal fat infiltration impacts spinal alignment and surgical outcomes, potentially necessitating revision lumbar fusion surgery.

Variability in Venous Thromboembolism Prophylaxis in Patients With Orthopedic Trauma at a Level 2 Trauma Center.

Patients with lower extremity orthopedic trauma are at increased risk of venous thromboembolism (VTE). American College of Surgeons data revealed that a New York Level 2 Trauma Center administered unfractionated heparin (UFH) four times more often, and low molecular weight heparin (LMWH) two-and-a-half times less often, than national averages, despite institutional and national guidelines supporting use of LMWH over UFH. We retrospectively reviewed VTE prophylaxis practices in adult patients with lower extremity orthopedic trauma at the institution to identify trends and/or aberrant administration.

Association between subaxial paraspinal muscle parameters and cervical vertebral bone quality in preoperative patients.

Objective: Evidence that individuals with osteoporosis have an increased susceptibility to and frequency of sarcopenia has led to the creation of the term "osteosarcopenia." Given the limitations of dual-energy X-ray absorptiometry in spine bone mineral density assessment, novel techniques such as MRI-based vertebral bone quality (VBQ) are increasingly being utilized to quantify site-specific bone quality in the spine. The relationship between cervical paraspinal muscle morphology and cervical bone quality has not been investigated.

Quantitative assessment of cervical disc degeneration using disc signal intensity index.

Background/context: The assessment of disc degeneration remains a significant challenge in clinical research. Pfirrmann grade is a frequently used classification for lumbar disc degeneration on MRI. However, there has been no gold standard for cervical spine disc degeneration.

Association Between Severity of Cervical Central Spinal Stenosis and Paraspinal Muscle Parameters in Patients Undergoing Anterior Cervical Discectomy and Fusion.

Study Design: Retrospective study.

Objective: The aim of this study was to evaluate the association between severity and level of cervical central stenosis (CCS) and the fat infiltration (FI) of the cervical multifidus/rotatores (MR) at each subaxial levels.

Summary Of Background Data: The relationship between cervical musculature morphology and the severity of CCS is poorly understood.

Association between severity of the cervical foraminal stenosis and paraspinal muscle parameters in patients undergoing anterior cervical discectomy and fusion.

Objective: The cervical multifidus and rotatores muscles are innervated by the posterior rami of the spinal nerves of the corresponding level, and it has been hypothesized that cervical foraminal stenosis (CFS) affecting the spinal nerves results in changes in these muscles. The purpose of this study was to evaluate the relationship between the severity of CFS and fat infiltration (FI) of the multifidus and rotatores muscles.

Methods: Patients who received preoperative cervical MRI, underwent anterior cervical decompression and fusion between 2015 and 2018, and met inclusion and exclusion criteria were included.

Association Between Cervical Sagittal Alignment and Subaxial Paraspinal Muscle Parameters.

Study Design: Retrospective review of prospectively collected data.

Objective: The authors aim to investigate the association between muscle functional group characteristics and sagittal alignment parameters in patients undergoing anterior cervical discectomy and fusion.

Summary Of Background Data: The relationship between the morphology of cervical paraspinal muscles and sagittal alignment is not well understood.

Comparing physiological responses during cognitive tests in virtual environments vs. in identical real-world environments.

Immersive virtual environments (VEs) are increasingly used to evaluate human responses to design variables. VEs provide a tremendous capacity to isolate and readily adjust specific features of an architectural or product design. They also allow researchers to safely and effectively measure performance factors and physiological responses.
