Introduction. Osteotomy or fracture models can be used to evaluate mechanical properties of fixation techniques of the hand skeleton in vitro. Although many studies make use of osteotomy models, fracture models simulate the clinical situation more realistically. This study investigates monocortical and bicortical plate fixation on metacarpal bones(More)
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)
PURPOSE To analyse the biomechanical characteristics of locking plates under cyclic loading compared to a nonlocking plate in a diaphyseal metacarpal fracture. METHODS Oblique diaphyseal shaft fractures in porcine metacarpal bones were created in a biomechanical fracture model. An anatomical reduction and stabilization with a nonlocking and a comparable(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)
