Fiber length variability within the flexor carpi ulnaris and flexor carpi radialis muscles: implications for surgical tendon transfer.
PURPOSE The purpose of this study was to understand the detailed architectural properties of the human flexor carpi radialis (FCR) and flexor carpi ulnaris (FCU) muscles and their implications for tendon transfer surgery. METHODS Muscle fiber length was measured in 6 separate regions of the FCU and FCR from 10 cadaveric specimens. Sarcomere length was measured by laser diffraction for normali...
متن کاملEnhanced propriospinal excitation from hand muscles to wrist flexors during reach-to-grasp in humans.
In humans, propriospinal neurons located at midcervical levels receive peripheral and corticospinal inputs and probably participate in the control of grip tasks, but their role in reaching movements, as observed in cats and primates, is still an open question. The effect of ulnar nerve stimulation on flexor carpi radialis (FCR) motor evoked potential (MEP) was tested during reaching tasks and t...
متن کاملEndoscopic Ganglionectomy of Palmar Ganglion via Flexor Carpi Radialis Tendoscopy
Palmar ganglion is rare. Deep palmar ganglion usually arises from the wrist joint and may cause compression neuropathy. Superficial palmar ganglion may arise from the flexor tendons of the wrist. The chance of compression neuropathy is expected to be less than deep palmar ganglion. However, there is a higher chance of perforation through the skin and the ganglion may affect hand grip. Open rese...
متن کاملSclerosing therapy and eccentric training in flexor carpi radialis tendinopathy in a tennis player.
BACKGROUND Tendinopathy of the flexor carpi ulnaris tendon is a rare entity. Recent research revealed the role of a neurovascular ingrowth at the point of pain in various tendinopathic locations, such as at the Achilles and patellar tendon, in plantar fasciitis as well as in supraspinatus and tennis elbow tendinopathy. However, beyond the elbow no such neovascularisation has been reported to da...
متن کاملThe flexor carpi radialis H-reflex in lesions of the sixth and seventh cervical nerve roots.
In 143 normal subjects latencies of H-reflexes of the flexor carpi radialis muscle were well correlated with arm lengths. In 32 patients with injury to cervical roots C5 to C8 it was shown that latencies were only abnormal in lesions of roots C6 or C7. It is suggested that in most instances root C6 or C7 and, probably both roots in some cases are involved in the reflex pathway. Repeat electroph...
