In this paper, we report a case of a 23-year-old male patient with bilateral absence of the flexor pollicis brevis and abductor pollicis brevis muscles with an intact functioning opponens pollicis and flexor pollicis longus muscles with bilateral thenar atrophy due to its rarity. All physical, neurological, ultrasonographic, direct radiographic, electromyographic and MRI studies were used to co...
Study Design Questionnaire. Objective To evaluate the ability of spine surgeons to distinguish C8-T1 radiculopathies from ulnar neuropathy. Methods Twenty-four self-rated "experienced" cervical spine surgeons completed a questionnaire with the following items. (1) If the ulnar nerve is cut at the elbow, which of the following would be numb: ulnar forearm, small and ring fingers; only the ulnar ...
The main cause of carpal tunnel syndrome (CTS) remains unknown. Stiffness of the subcutaneous area of the volar aspect of the carpal tunnel is present in many patients and suggests that the stiffness of muscles attached to the transverse carpal ligament is increased. We performed an electrophysiological study to investigate muscle activities and to clarify whether the stiffness of muscles attac...
BACKGROUND The intramuscular nerve distribution and relative spindle abundance of the human hand have not been well defined, although this is important in guiding hand surgery. METHODS Forty human hands were dissected and subjected to modified Sihler's stain and haematoxylin and eosin stain to investigate intramuscular nerve distribution and relative spindle abundance, respectively. RESULTS...
Although the etiology of osteoarthritis of the thumb carpometacarpal (CMC) joint remains unclear, some theories have focused on variations in the local anatomy of the abductor pollicis longus tendon insertion. This cadaver study of 68 specimens analyzed the relationship between a thenar insertion of an accessory abductor pollicis longus tendon and the presence and severity of thumb CMC osteoart...
We report a rare case of a 10-year-old girl with anomalous course of extensor pollicis longus (EPL) muscle, which exists with absence of thenar muscles and muscles in the 1st extensor compartment. Her chief complaint was severe atrophy on the right thenar eminence. On physical examination, there was no obvious functional abnormality on her right thumb. On magnetic resonance imaging, we found th...
Because of its variable origin and course, the thenar branch median nerve is at risk during carpal tunnel release. Transection results in atrophy non-functioning opponens pollicis, abductor pollicis brevis flexor muscles. A late neurorrhaphy hypothenar fat pad flap were performed to restore conduction thus muscle function after accidental transection an open release 216 days earlier. During eig...
