The application of regenerative therapies for the treatment of musculoskeletal conditions has emerged over the last decade with recent acceleration. These include prolotherapy, platelet-rich plasma, and mesenchymal stem cell therapy. These strategies augment the body's innate physiology to heal pathologic processes. This article presents an overview of platelet-rich plasma and mesenchymal stem cell therapy for the treatment of musculoskeletal injuries. A brief literature review is included, as are techniques for the use of ultrasound guidance to assist with these procedures...

Trauma and the mechanical strain of high-energy activity predispose athletes to pelvic injuries. Magnetic resonance imaging remains the primary modality for diagnosing these conditions, but ultrasonography-guided interventions are important in the management of core muscle, hip, and other pelvic conditions. This article reviews ultrasonography-guided interventions for injuries at the core, including the pelvis and hips. It reviews common injuries, procedure optimization, medication preparation, clinical evidence behind injections, tenotomy, and platelet-rich plasma...

BACKGROUND/AIM: In a condition of pain in the Achilles tendon insertion there are multiple structures involved, such as the Achilles tendon itself, the retrocalcaneal bursa and a bony protrusion at the calcaneal tuberosity called Haglund's deformity. The innervation patterns of these structures are scarcely described, and the subcutaneous calcaneal bursa is traditionally not considered to be involved in the pathology. This study aimed at describing the innervation patterns of the four structures described above to provide a better understanding of possible origins of pain at the Achilles tendon insertion...

This article presents possible applications of ultrasound elastography in musculoskeletal imaging based on the available literature, as well as the possibility of extending indications for the use of elastography in the future. Ultrasound elastography (EUS) is a new method that shows structural changes in tissues following application of physical stress. Elastography techniques have been widely used to assess muscles and tendons in vitro since the early parts of the twentieth century. Only recently with the advent of new technology and creation of highly specialized ultrasound devices, has elastography gained widespread use in numerous applications...

OBJECTIVE: The primary objective of this study was to compare the cutaneous size of a bruise on gross exam to the subcutaneous depth and height of the hematoma ascertained by ultrasound. The hypothesis was that there would be little correlation between the area of the bruise on cutaneous exam and the height when measured with ultrasound. METHODS: Adult and pediatric patients with bruising were prospectively identified in the emergency department. Photographs and ultrasound images were collected of the bruises and epidemiologic information collected from the patients...

Ultrasound use has expanded dramatically among the medical specialties for diagnostic and interventional purposes, due to its affordability, portability, and practicality. This imaging modality, which permits real-time visualization of anatomic structures and relationships in vivo, holds potential for pre-clinical instruction of students in anatomy and physical diagnosis, as well as providing a bridge to the eventual use of bedside ultrasound by clinicians to assess patients and guide invasive procedures. In many studies, but not all, improved understanding of anatomy has been demonstrated, and in others, improved accuracy in selected aspects of physical diagnosis is evident...

Ulnar neuropathy is caused by compression of the ulnar nerve in the upper extremity, frequently occurring at the level of the elbow or wrist. Rarely, ulnar nerve entrapment may be seen proximal to the elbow. This report details a case of ulnar neuropathy diagnosed and localized to the arcade of Struthers with electromyography (EMG) and ultrasound (US) imaging and confirmed at time of operative release. US imaging and EMG findings were used to preoperatively localize the level of compression in a patient presenting with left ulnar neuropathy...

PURPOSE: Isolated tenotomy of the long head of the biceps (LHB) is known to improve function in patients with massive and non-reparable cuff tears without osteoarthritis. This two step cadaveric study was performed with the purpose to identify the best surgical technique for isolated LHB tenotomy under USG guidance (pilot study) and evaluate its feasibility (subsequent study). METHODS: Pre-operative ultrasonographic evaluation of the rotator cuff was performed and any specimens whose long head of the biceps was not found to be intact during the pre-operative ultrasound evaluation were excluded...

Ultrasound is a non-invasive, fast, relatively inexpensive and available tool for estimating adiposity in clinical practice, and in several research settings. It does not expose patients to ionizing radiation risks, making the method ideal for the evaluation, and for follow-up studies. Several parameters and indexes based on adipose tissue thickness have been introduced and tested, and these have been correlated with clinical and laboratoristic parameters. Moreover, ultrasound can also be directed to the estimation of adipose tissue and intracellular fat indirectly, at cellular-molecular level: an opportunity for many radiologists who already and sometimes unconsciously perform "body composition" assessment when looking at the liver, at muscle as well as at other organs...

Sule Sahin Onat, Ayse Merve Ata, Levent Ozcakar
Meralgia paresthetica refers to the entrapment of the lateral femoral cutaneous nerve at the level of the inguinal ligament. The lateral femoral cutaneous nerve - a purely sensory nerve - arises from the L2 and L3 spinal nerve roots, travels downward lateral to the psoas muscle, and then crosses the iliacus muscle. Close to the anterior superior iliac spine, the nerve courses in contact with the lateral aspect of the inguinal ligament and eventually innervates the lateral thigh. The entrapment syndrome is usually idiopathic but can also ensue due to trauma/overuse, pelvic and retroperitoneal tumors, stretching of the nerve due to prolonged leg/trunk hyperextension, leg length discrepancies, prolonged standing, external compression by belts, weight gain, and tight clothing...

Sathish Rajasekaran, Mederic M Hall
Although nonoperative treatment options for chronic exertional compartment syndrome (CECS) are often used in clinical practice, supporting evidence is limited. The objective of this study was to systematically review the literature for nonsurgical treatment options for CECS of the lower leg. The literature search identified seven articles describing in total four different treatment options: massage, gait changes, chemodenervation, and ultrasound-guided (USG) fascial fenestration. Pertinent studies were in the form of case series and one case report, which limited the robustness of the data...
