Introduction:The immune system plays a pivotal role in nerve injury. The aim of this study was to investigate the role of multi-parametric magnetic resonance (MR) imaging in the evaluation of the synergic effect of immunomodulation on nerve regeneration in neurotmesis. METHODS: Rats with sciatic nerve neurotmesis and surgical repair underwent serial multi-parametric MR examinations over an 8 week period after subepineurial microinjection of lipopolysaccharide (LPS) and subsequent subcutaneous injection of FK506 or subepineurial microinjection of LPS or phosphate buffered saline (PBS) alone...

Digital nerves are intrinsic to the sensory and motor function of the hand. These nerves represent the terminal ramifications of the ulnar, median, and radial nerves and are located distal to the carpal tunnel and Guyon canal. With magnetic resonance imaging, traumatic and nontraumatic abnormalities of the digital nerves can be shown with high contrast as well as high spatial resolution. Digital nerve abnormalities are most commonly posttraumatic in nature; however, infection, inflammatory, vascular malformations, and neoplasms can rarely occur...

The management of pink pulseless limbs in supracondylar fractures has remained controversial, especially with regards to the indication for exploration in a clinically well-perfused hand. We reviewed a series of seven patients who underwent surgical exploration of the brachial artery following supracondylar fracture. All patients had a non-palpable radial artery, which was confirmed by Doppler ultrasound. CT angiography revealed complete blockage of the artery with good collateral and distal run-off. Two patients were more complicated with peripheral nerve injuries, one median nerve and one ulnar nerve...

INTRODUCTION: The median and radial nerves are two important neural structures found in the cubital fossa. The trajectory and landmarks used to identify their location are important when procedures are done in this area. METHODS AND MATERIALS: Ten fresh-frozen cadavers were dissected (20 upper limbs) and measurements were taken from the medial epicondyle to the median and radial nerves as well as to the lateral epicondyle of each limb. RESULTS: The distance between the medial epicondyle and the median nerve was found to be three centimeters with a range of 2...

Massage related nerve injury is an uncommon, rarely reported complication. We report an unusual case of radial nerve neuropathy at the spiral groove in a 58 years old woman resulting from a single episode of deep tissue massage. Although the spiral groove is known as the most common site implicated in radial nerve neuropathy, to our knowledge, there have not previously been any reports of massage related spiral groove radial nerve neuropathy. Electrodiagnostic and ultrasound examinations were used to localize the nerve lesion at the spiral groove on the affected side...

BACKGROUND: Brachial arterial catheters better estimate aortic pressure than radial arterial catheters but are used infrequently because complications in a major artery without collateral flow are potentially serious. However, the extent to which brachial artery cannulation promotes complications remains unknown. The authors thus evaluated a large cohort of cardiac surgical patients to estimate the incidence of related serious complications. METHODS: The institutional Society of Thoracic Surgeons Adult Cardiac Surgery Database and Perioperative Health Documentation System Registry of the Cleveland Clinic were used to identify patients who had brachial artery cannulation between 2007 and 2015...

This study compared how wheelchair propulsion styles affect changes in percentage of time spent in extreme wrist orientations, which have been associated with median nerve injury, after a fatiguing bout of propulsion. Twenty novice, non-disabled adult males learned arcing (ARC) and semicircular (SEMI) propulsion styles and utilised each to perform a wheelchair fatigue protocol. ARC and SEMI did not significantly differ in terms of changes after the fatigue protocol in percentage of time spent in extreme flexion/extension or radial/ulnar deviation at the push phase beginning or end...

RATIONALE: Elbow injury in children by improper treatment or a delay of more than 3 weeks could lead to old unreduced Monteggia fracture, which are difficult to manage. Conservative or normal surgical methods usually fail. PATIENT CONCERNS: Herein, we present a 6-year-old boy with sustaining injury approximately 1 month to his left elbow. Activity in his elbow was restricted, and his ability to extend his wrist and fingers was impaired. DIAGNOSES: Type III Monteggia elbow fracture-dislocation consisting of radial head dislocation and malunion of the ulna associated with posterior interosseous nerve palsy were confirmed, which requiring surgical treatment...

BACKGROUND: Regeneration of the damaged central nervous system is one of the most interesting post-embryonic developmental phenomena. Two distinct cellular events have been implicated in supplying regenerative neurogenesis with cellular material - generation of new cells through cell proliferation and recruitment of already existing cells through cell migration. The relative contribution and importance of these two mechanisms is often unknown. METHODS: Here, we use the regenerating radial nerve cord (RNC) of the echinoderm Holothuria glaberrima as a model of extensive post-traumatic neurogenesis in the deuterostome central nervous system...

Pseudoaneurysm of the radial artery is extremely rare. It usually occurs secondary to trauma, interventional procedures, and infections. Symptoms occur due to mass effect by the pseudoaneurysm, digital ischemia, or nerve suppression. B-mode and color Doppler ultrasonography are the first choice in diagnosis. The pathognomonic ultrasound sign of pseudoaneurysm is the turbulent flow, which is called the "ying-yang" sign. Bandages, ultrasound probe compression, ultrasound-guided thrombin injection, covered stents, and surgical ligation can be used in treatment...
