PURPOSE The aim of the present study was to characterize the cell of the human periosteum using immunohistological and molecular methods. METHODS Phenotypic properties and the distribution of the cells within the different layers were investigated with immunohistochemical staining techniques and RT-PCR, focussing on markers for stromal stem cells,(More)
Shoulder dislocations with fractures are a possible complication of an epileptic seizure and are often missed on the first sight. The incidence of sustaining an avascular humeral head necrosis (AVN) is high, and primary prosthetic replacement is the choice of treatment. In this paper, we describe such a rare case: a 48-year-old male patient sustained(More)
BACKGROUND Suture pretension during tendon repair is supposed to increase the resistance to gap formation. However, its effects on the Bunnell suture technique are unknown. The purpose of this study was to determine the biomechanical effects of suture pretension on the Bunnell and cross-lock Bunnell techniques for tendon repair. METHODS Eighty porcine(More)
Somatosensory evoked potentials (SEP) of the tibial nerve are of diagnostic value, if the recording points nearest to the spinous process are used. In cases with space-occupying lesions of the spinal cord, conduction block or amplitude reduction is the most common abnormality. In contrast in inflammatory diseases like spinal MS the most common abnormality(More)
In 33 normal subjects aged between 15 and 60 years, the cortical somatosensory evoked potentials (SEP) recorded above the mastoid process, HWK2, LWK1, and the nerve action potential above the poplitea were examined following single stimulation of the tibial nerve at the medial malleolus. There is a correlation between size and N1, P1 latencies of the(More)
