During routine cadaveric dissection of the upper extremity an unusual muscle was discovered arising from the tendon of the flexor carpi ulnaris and inserting into the muscle belly of the flexor digiti minimi. The muscle's course was superficial to the ulnar nerve and artery in Guyon's canal. We review the literature regarding such muscle variations and discuss the potential for compression of t...

Extramuscular connective tissue and muscular fascia have been suggested to form a myo-fascial pathway for transmission of forces over a joint that is additional to the generally accepted myo-tendinous pathway. The consequences of myo-fascial force transmission for the outcome of conventional muscle tendon transfer surgery has not been studied as yet. To test the hypothesis that surgical dissect...

BACKGROUND The main problem of tremor is the damage caused to the quality of the life of patients, especially those at more advanced ages. There is not a consensus yet about the origins of this disorder, but it can be examined in the correlations between the biological signs of aging and the tremor characteristics. METHODS This work sought correlations between the osmotic fragility of erythro...

A 13-year-old girl occasionally felt pain on the ulnar side of her right wrist before her right forearm abruptly locked in the pronated position while playing basketball. She had no pain or swelling after the injury; and after a month of therapy, she was seen at our hospital. On physical examination, the right forearm was locked in 70” pronation. When supination was attempted, the patient felt ...
