Background Although foveal tears of the triangular fibrocartilage complex (TFCC) can be surgically reattached to the fovea via a dorsal approach, the foveal lesion is difficult to visualize from the dorsal side because the extensor carpi ulnaris (ECU) sheath floor and the superficial dorsal limb of the radioulnar ligament hinders the view of the fovea. Materials and Methods Twenty-one patients ...

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...

INTRODUCTION Pseudoaneurysm of the hand is a rare condition; most are treated surgically. Ultrasound guided thrombin injection has not previously been reported as a treatment option for pseudoaneurysms of the deep palmar arch. REPORT A man was referred to the emergency department with a swollen, painful hand after penetrating trauma. On physical examination, a pulsating tumor was found on the...

Dorsiflexion, palmar flexion, ulnar translocation, and dorsal carpal subluxation are four, not uncommon, post-traumatic carpal ligamentous instabilities. Palmar carpal subluxation is a theoretical possibility. Dorsiflexion and palmar flexion instabilities are named for the way the distal lunate articular surface dorsally and palmarly, respectively. Ulnar translocation, and dorsal and ventral ca...

Hypervelocity impact (HVI), ubiquitous in low Earth orbit with an impacting velocity in excess of 1 km/s, poses an immense threat to the safety of orbiting spacecraft. Upon penetration of the outer shielding layer of a typical two-layer shielding system, the shattered projectile, together with the jetted materials of the outer shielding material, subsequently impinge the inner shielding layer, ...

Stress-corrosion cracking (SCC) tests were conducted in the near-neutral pH standard solution, NS4, and in an actual soil solution, using four-point bending at a high stress ratio and low frequency conditions very similar to those of operational pipelines. Pitting incubation appeared first and then pitting initiated and grew in both solutions although there were many more pits on the specimen t...

A 73-year-old man with a history of myasthenia gravis (MG) was diagnosed with rheumatoid arthritis (RA) based on a history of polyarthritis and positivity for anti-citrullinated protein antibodies (ACPA). He presented with a high level of serum vascular endothelial growth factor (VEGF) and RS3PE syndrome-like pitting edema in the extremities, which improved following treatment with low-dose pre...
