The normal grip strength was determined with the Martin Vigorimeter in 450 men and women aged 21--65 years. The grip strength decreased steadily with increasing age. Men were stronger than women and in both sexes the dominant hand was the strongest. The ratio dominant/non-dominant hand varied only slightly with age and sex and it could thus be a useful(More)
In 16 patients, where the diagnosis carpal tunnel syndrome was electrophysiologically confirmed, the pressure between the median nerve and the carpal ligament was measured peroperatively. At rest the pressure was 18-64 mmHg, mean 31 mmHg. Passive volar and dorsal wrist flexion increased the pressure about three times. Isometric or isotonic maximal(More)
The pressure between the ulnar nerve and the arcade bridging the two heads of the flexor carpi ulnaris muscle was recorded peroperatively in ten patients with electrophysiologically confirmed ulnar neuropathy at the elbow. At rest, with the elbow extended, pressures ranged from 0 to 19 mm Hg but increased in flexion and during isometric contraction of the(More)
The incidence of upper extremity fractures was 8.8 per 1,000 inhabitants per year. Five per cent of these fractures occurred in the subcapital region of the fifth metacarpal bone. In a patient series the volar angulation after subcapital fracture of the fifth metacarpal bone was determined with a novel technique and related to functional and cosmetic(More)
Four cases of the anterior interosseous nerve syndrome, which were treated by neurolysis, are added to the sixty-five already described in the literature. The onset of symptoms is usually spontaneous and electrophysiological examination is of value in making the diagnosis. The most frequent cause of the entrapment is fibrous bands in the pronator teres(More)
Entrapment of the posterior interosseous nerve has been distinguished as one cause of 'lateral elbow' pain. However, this diagnosis has been confirmed by routine neurophysiological techniques in rather few cases. In order to investigate if a more elaborate neurophysiological technique would lend further support to the entrapment diagnosis, a study was(More)

This paper presents ten cases of radial nerve paralysis because of tumor and reviews 38 previously reported cases. The tumor distribution was 35 lipomas, four neurofibromas, four ganglions, three neuromas, one fibroma, and one neurilemoma. Malignant tumors are not discussed in this review. Electromyography is of value if diagnostic problems occur.(More)
The present study shows the occurrence of the trichorhinophalangeal syndrome type I in a Swedish family. Five members were affected and they were examined clinically and radiologically, and four of them were also cytogenetically examined. Three of them had dysplasia of the hip joints reminiscent of the Legg-Calvé-Perthes disease. Functional hand problems(More)
The radial tunnel syndrome is recognized as on cause of lateral elbow pain. This investigation demonstrated pressures of 40--50 mmHg exerted on the posterior interosseus herve by the edge of the superficial supinator muscle during passive stretch of the supinator muscle. During active muscle contraction caused by tetanic nerve stimulation, the pressure was(More)
