background: a glass injury to the wrist and forearm is a common condition in adults and children that may cause significant discomfort and disability. this study was conducted to evaluate the accuracy of preoperative examination of this injury. methods: in this prospective study, among patients referred to kashani hospital in isfahan, iran from august 2006 to march 2008, 150 patients with glass...

The aims of this study were to explore muscle activity levels during different violin repertoires, quantify the general bilaterally in upper extremity muscles, and evaluate associations between anthropometrics characteristics. In 18 skilled players surface EMG was recorded from trapezius (UT), flexor digitorum superficialis (FDS), extensor carpi ulnaris (ECU), cummunis (EDC), radialis (ECR) A E...

The anterior interosseous nerve syndrome involves paralysis of the flexor pollicis longus, flexor digitorum profundus of the index and long fingers, and the pronator quadratus. We have encountered 33 cases of an incomplete syndrome in which only the flexor pollicis longus or the flexor digitorum profundus of the index finger is either paretic or paralyzed. This entity must be distinguished from...

PURPOSE To quantify the gain in muscle mobility with progressive release of surrounding connective-tissue structures and to compare this property with the known architecture of each muscle. METHODS Each of 5 different muscle tendon units (extensor carpi radialis brevis, extensor carpi radialis longus, flexor carpi ulnaris, flexor digitorum superficialis, pronator teres) was released from its ...

A patient affected by thoracic outlet syndrome, with an involvement of the left lower primary trunk due to a rudimentary cervical rib, developed a severe hand dystonia on the same side. The dystonic posture was characterised by a flexion of the wrist with the fingers curled into the palm. Polygraphic recordings performed on the left flexor digitorum superficialis (FDS4) and extensor digitorum s...

This study investigated the potential influence of proximal sensory feedback on voluntary distal motor activity in the paretic upper limb of hemiparetic stroke survivors and the potential effect of voluntary distal motor activity on proximal muscle activity. Ten stroke subjects and 10 neurologically intact control subjects performed maximum voluntary isometric flexion and extension, respectivel...

BACKGROUND Nonabsorbable sutures are favorable for repairing flexor tendons. However, absorbable sutures have performed favorably in an animal model. METHODS Two-strand sutures using the interlocking modified Kessler method with polydioxanone absorbable sutures 4-0 were used to repair completely ruptured flexor tendons in 55 fingers from 41 consecutive patients. The medical records of average...
