BACKGROUND To present the medium-term results of intra-articular, bicondylar AO/OTA classification type C fractures of the tibial plateau in a retrospective study at a level-1 trauma center in 22 patients with 23 fractures. METHODS Demographic data for the patients and details of current clinical and radiological follow-up findings were obtained to assess(More)
Axial burst fractures of the distal tibia are challenging to treat and often lead to restricted function of the lower limb. The purpose of this study was to investigate the clinical outcome and changes in gait pattern in such patients. Thirty-five patients in a level 1 trauma centre were followed up clinically and by gait analysis. The American Orthopaedic(More)
OBJECTIVE Fixation of ankle fractures in elderly patients is associated with reduced stability conditioned by osteoporotic bone. Therefore, fixation with implants providing improved biomechanical features could allow a more functional treatment, diminish implant failure and avoid consequences of immobilisation. MATERIALS AND METHODS In the actual study,(More)
The aim of this study was to determine the biomechanical characteristics of locking plates with the TriLock system with different design and screw settings compared to a non-locking plate in a diaphyseal metacarpal fracture. Oblique diaphyseal shaft fractures in porcine metacarpal bones were created in a biomechanical fracture model. After reduction they(More)
The purpose of this study was to characterise the biomechanical properties of the seven hole superior anterior clavicle LCP (locking compression plate) and to compare these with the properties of commonly applied implants used for the stabilisation of clavicular midshaft fractures such as the locking 7- and ten hole reconstruction plate. Twenty-four(More)
To investigate the clinical outcome and gait analysis findings by dynamic pedobarography in patients following surgically treated single, closed, dislocated intra-articular calcaneal fractures. Retrospective single-center study with 26 patients. The average follow-up period was 34 months (range 18–61 months). We used the Zwipp score and a score based on a(More)
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)
The aim of this study was to investigate a new drillable calcium phosphate cement (Norian drillable Synthes GmbH) as a bone substitute either alone or in combination with screws in the jail technique (Petersen et al. Unfallchirurg Mar 109(3):219–234, 2006; Petersen et al. Unfallchirurg Mar 109(3):235–244, 2006) with regard to the primary stability in(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)
BACKGROUND To investigate the potential influence of patient age on fracture type and postoperative mobility in subtrochanteric femoral fractures. METHODS Data for patients who had suffered subtrochanteric femoral fractures between 2004 and 2009 were analyzed in a retrospective single-center study at a level I trauma center. Age, sex, accident cause,(More)
