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)
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 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)
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)
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)
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)
To investigate whether effort-related dorsal forearm pain could be due to an increase of the intracompartmental pressure (ICP) in the dorsal forearm compartment, the normal range of the ICP at rest and during exercise was first determined in 11 volunteers using a wick catheter. The ICP at rest was 6 mm Hg (range, 2-11 mm Hg), and during exercise the(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)
