a few numbers of patients admitted to the emergency department due to the lunate dislocation can cause a direct injury to the wrist ligament, which mainly occurs after wrist trauma, and often diagnosis is far from the mind. a 32 years old man due to severe pain and tenderness of the wrist started the previous day during swimming, referred to emergency department of imam reza hospital of mashhad...

median cleft is the midline cleft of the lip. it develops due to incomplete or failed fusion of the median nasal prominence. it can present with minimal deformities such as involvement of the vermilion border, or complex clefting of the midline structures and brain. median clefts are broadly classified as true and false clefts. this case report describes a rare case of median cleft of the upper...

Hemangiomas of the median nerve are extremely rare; only 12 cases have been reported in the literature. We discuss a patient who presented with paresthesia and pain along the distribution of the left median nerve secondary to a cavernoma of the proximal part of the nerve as suspected on MRI scan. Total removal of the mass was achieved with immediate relief of the symptoms and no neurologic defi...

background: compressive neuropathy of median nerve is relatively common but development of an hourglass like constriction is a rare phenomenon. the purpose of this study is to show morphologic changes of median nerve in advances carpal tunnel syndrome. methods: eighty patients with thenar atrophy, anesthesia and paresthesia of first, second and third finger and severe changes of emg‑ncv were ch...

atypical connections in the formation of the brachial plexus are prevalent and have been reported in different articles. the present report describes a case of variation of the median nerve observed in the iranian male cadaver during routine trial dissection. there are three roots for median nerve. median nerve is formed by joining two lateral and medial cords of brachial plexus. third root of ...

Introduction. The geometric median is a classic robust estimator of centrality for data in Euclidean spaces, and it has been generalized in analytical manifold in [1]. Recently, an intrinsic Riemannian framework for Orientation Distribution Function (ODF) was proposed for the calculation in ODF field [2]. In this work, we prove the unique existence of the Riemannian median in ODF space. Then we...

background: few reports represent palmar cutaneous nerve neuropathy in the wrist due to a ganglion cyst. case presentation: a 25-year-old female was presented with a mass at volar side of the wrist and hypoesthesia at the base of thenar eminence. at ulrasonographic examination, a simple cyst was detected. sensory response of palmar cutaneous branch of median nerve was absent at the affected sid...

background: surface electromyography (semg) of muscles is a non-invasive tool that can be helpful in the assessment of muscle function and some motor control evaluations. a loss of force, known as muscle fatigue is accompanied by changes in muscle electrical activity. one of the most commonly used surface emg parameters which reflects paraspinal muscle fatigue during different tasks and positio...
