A new radiological index for the assessment of higher body fat status and lumbar spine degeneration.
Obesity has been proposed as a risk factor for low back pain (LBP) and intervertebral disc degeneration (IVDD). Even though body mass index (BMI) is used as a parameter for obesity, it could not represent percentage and distribution of the body fat. Subcutaneous fat tissue thickness (SFTT) was proposed as one of the magnetic resonance imaging (MRI) parameters to evaluate the percentage of the body fat. In this study, we aimed to find out whether SFTT at lower back correlated with LBP and spine degeneration. ⋯ SFTT at upper lumbar levels could predict severe IVDD and Modic changes better than BMI, specifically in men. SFTT was better than BMI in predicting a symptomatic patient with LBP.

Vaccination injection site adverse reactions are usually mild and transient, and post-vaccination musculoskeletal symptoms, such as myalgia and arthralgia, are very common. Shoulder injury related to vaccine administration (SIRVA), defined as shoulder pain and limited range of motion occurring after the administration of a vaccine intended for intramuscular administration in the upper arm, is a well-established condition in the medical literature, yet underreported. ⋯ Millions of doses of vaccines for the prevention of COVID-19 have been administered to adults worldwide during the pandemic. We report a case of subacromial-subdeltoid bursitis after COVID-19 vaccination, related to the unintentional injection of vaccine solution into the bursa resulting in a robust immune-mediated inflammatory reaction.

Beirut port explosion: unusual presentation of bilateral blast-related extensor mechanism rupture.
Industrial disasters related to high-order explosives result in characteristic injuries that are seldom seen among civilians. Survivors of these disasters often present with injuries of the musculoskeletal system. ⋯ He was standing 1.5 miles from the site of the site of explosion of the port of Beirut on August 4, 2020. We discuss the imaging appearance of this injury, the different mechanisms of blast-related injuries, the role of possible underlying pathology, and the management of this patient.

Musculoskeletal pain is a debilitating problem treated with image-guided corticosteroid injections. During the COVID-19 pandemic, multiple societies issued caution statements because of the unknown effect of corticosteroids on the patient's immune system. The purpose is to determine if image-guided corticosteroid injections administered during the COVID-19 lockdown phase were associated with a higher infection rate compared to the general population. ⋯ Image-guided corticosteroid injections for pain management performed during the lockdown phase of the COVID-19 pandemic were not associated with a higher infection rate compared to the general population.

To analyze the safety and efficacy of image-guided genicular nerve cooled radiofrequency ablation (C-RFA) for the treatment of pain in non-surgical candidates with moderate to severe knee osteoarthritis (OA) and to compare three- vs four-needle technique. ⋯ The four-needle treatment approach offers an advantage in the overall efficacy in treating stiffness and pain in patients with moderate-to-severe OA refractory to conservative treatments leading to decreased opiate usage without complications.
