Adipose Tissue As Pain Generator In The Lower Back And Lower Extremity: Application In Musculoskeletal Medicine, Se Won Lee, Craig Van Dien, Sun Jae Won Oct 2020

Adipose Tissue As Pain Generator In The Lower Back And Lower Extremity: Application In Musculoskeletal Medicine, Se Won Lee, Craig Van Dien, Sun Jae Won

HCA Healthcare Journal of Medicine

Adipose tissue (AT) has diverse and important functions in body insulation, mechanical protection, energy metabolism and the endocrine system. Despite its relative abundance in the human body, the clinical significance of AT in musculoskeletal (MSK) medicine, particularly its role in painful MSK conditions, is under-recognized. Pain associated with AT can be divided into intrinsic (AT as a primary pain generator), extrinsic (AT as a secondary pain generator) or mixed origin. Understanding AT as an MSK pain generator, both by mechanism and its specific role in pain generation by body region, enhances the clinical decision-making process and guides therapeutic strategies in …

Post-Influenza Vaccine Subdeltoid Bursitis, Marenda Jenkins, David Rupp, Lynne J. Goebel

Internal Medicine

A 61-year-old female presented three months following an influenza vaccination with ongoing pain since the injection and was diagnosed by MRI with subdeltoid bursitis. The patient received a short course of prednisone and several months of physical therapy before returning to pain-free function. The primary reason for injection-related subdeltoid bursitis is improper administration. It is a preventable issue, and improved training of healthcare workers on proper vaccine administration may decrease its occurrence.

The Role Of Nerves In Skeletal Development, Adaptation, And Aging., Ryan E Tomlinson, Blaine A Christiansen, Adrienne A Giannone, Damian C Genetos

Department of Orthopaedic Surgery Faculty Papers

The skeleton is well-innervated, but only recently have the functions of this complex network in bone started to become known. Although our knowledge of skeletal sensory and sympathetic innervation is incomplete, including the specific locations and subtypes of nerves in bone, we are now able to reconcile early studies utilizing denervation models with recent work dissecting the molecular signaling between bone and nerve. In total, sensory innervation functions in bone much as it does elsewhere in the body-to sense and respond to stimuli, including mechanical loading. Similarly, sympathetic nerves regulate autonomic functions related to bone, including homeostatic remodeling and vascular …
