Presynaptic inhibition of transmission between Ia afferent terminals and alpha motoneurons (Ia PSI) is a major control mechanism associated with soleus H-reflex modulation during human locomotion. Rhythmic arm cycling suppresses soleus H-reflex amplitude by increasing segmental Ia PSI. There is a reciprocal organization in the human nervous system such that arm cycling modulates H-reflexes in l...

Currently, radial artery cannulation is the preferred method for continuous hemodynamic monitoring in critically ill patients. Reported complications of radial artery cannulation include infection, digital gangrene, thrombosis, pseudoaneurysm, skin necrosis and median nerve palsy. Radial artery catheter fracture is a very rare complication. A review of the English language literature revealed o...

Skeletal muscle architecture is one of the most important properties that determines a muscle's force and excursion capability. In the current review, basic architectural terms first are reviewed and then specific examples relevant to upper extremity anatomy are presented. Specific examples of anatomic considerations required for surgical reconstruction after radial nerve palsy also are detaile...

Whether interlimb reflexes emerge only after a severe insult to the human spinal cord is controversial. Here the aim was to examine interlimb reflexes at rest in participants with chronic (>1 year) spinal cord injury (SCI, n = 17) and able-bodied control participants (n = 5). Cutaneous reflexes were evoked by delivering up to 30 trains of stimuli to either the superficial peroneal nerve on the ...

The sensory territories of different cutaneous fascicles of the superficial radial nerve were delineated by microneurography at the level of the distal forearm in humans. Three fascicular patterns were found at this level: one supplying the dorsum of the radial aspect of the dorsum of the hand over the first dorsal interosseous space; another supplying the lateral aspect of the first metacarpal...

BACKGROUND Correction of a distal radius fracture malunion is challenging technically. These malunions most classically deform dorsally, but often the deformity involves three planes. METHODS Using an anatomically designed radial plate that takes into consideration the three planes, correction of the deformity can be obtained. In this video we see a patient with a classic dinner fork deformit...

OBJECTIVES There are various pin-in-plaster methods for treating fractures of the distal radius. The purpose of this study is to introduce a modified technique of 'pin in plaster'. METHODS Fifty-four patients with fractures of the distal radius were followed for one year post-operatively. Patients were excluded if they had type B fractures according to AO classification, multiple injuries or ...

Radial tunnel syndrome is a disease which we should consider it in elbow and forearm pains. It is diagnosed with lateral elbow and dorsal forearm pain may radiate to the wrist and dorsum of the fingers. The disease is more prevalent in women with the age of 30 to 50 years old. It occurs by intermittent compression on the radial nerve from the radial head to the inferior border of the supinator ...

Introduction The axillary nerve comes from the posterior cord of the brachial plexus at the level of the axilla and carries nerve fibers from C5 and C6. The axillary nerve travels through the quadrangular space with the posterior circumflex humeral vessels, and divides into anterior and posterior branches. It supplies deltoid and teres minor. It carries sensory information from the shoulder joi...

account for approximately 3% of all biceps tendon ruptures. The two-incision repair techniques, as described by Boyd and Anderson1 in 1961, were developed to lower the risk of injury to the radial nerve and posterior interosseous nerve. Reports of posterior interosseous nerve palsy following this approach are rare.2-3 Transient posterior interosseous nerve palsies following a repair with the tw...
