Effective treatment of periprosthetic fractures following TKA continues to represent a surgical challenge. The incidence and frequency of these complicated type of fractures is expected to increase as the number of TKA as well as the activity level of these patients steadily rises. A careful and correct analysis of the fracture pattern, its classification,(More)
BACKGROUND This study aimed to investigate the influence of the screw location and plate working length of a locking plate construct at the distal femur on interfragmentary movement under physiological loading. METHODS To quantitatively analyse the influence of plate working length on interfragmentary movements in a locking plate construct bridging a(More)
UNLABELLED PURPOUSE OF THE STUDY: Wound drainage in surgical interventions has a long tradition. Regarding the primary TKA there are no valid data concerning the ideal point of time for removal. The objective of this prospective randomized study was to investigate which drainage procedure should be given preference with regard to wound healing, blood loss,(More)
This study compared the quality of reduction and complication rate when using a standard ilioinguinal approach and the new pararectus approach when treating acetabular fractures surgically. All acetabular fractures that underwent fixation using either approach between February 2005 and September 2014 were retrospectively reviewed and the demographics of the(More)
Pilonidal sinus disease (PSD) most commonly presents in young men when hair follicles enter through damaged epithelium and cause an inflammatory reaction. This results in the formation of fistular tracts. We reviewed studies based on a shared cohort of patients who presented at German military hospitals with PSD. The effect of the morphology of the sinus,(More)
The tibia shaft is the most often fractured long bone of human beings. Among others traffic accidents (37.5 %), falls (17.8 %), sport accidents (30.9 %) and assaults (4.5 %) are typical mechanisms. A brief clinical examination including the correct classification of the fracture pattern and even more important the degree of the soft tissue damage are the(More)
BACKGROUND Extent and orientation of interfragmentary movement (IFM) are crucially affecting course and quality of fracture healing. The effect of different configurations for implant fixation on successful fracture healing remain unclear. We hypothesize that screw type and configuration of locking plate fixation profoundly influences stiffness and IFM for(More)
This study aimed to analyse functional outcome and quality of life (QoL) after surgical treatment of periprosthetic femoral fractures (PPF) following total hip arthroplasty (THA). This retrospective study assessed 67 patients from 2005 to 2012. Epidemiologic data, surgical details, comorbidities, deaths and postoperative complications were recorded.(More)
The incidence of periprosthetic fractures is inevitably increasing. Sufficient stabilisation and proper screw placement next to large-volume implants remains difficult. Modern locking plates allow polyaxial, thus bicortical, screw placement around a prosthetic stem. This study analysed the biomechanical properties of different screw configurations in a(More)
Although it remains the golden standard, several authors have questioned the role of pneumatic tourniquets in primary knee arthroplasty in recent studies. An intra-articular wound drainage is widely used in the field of total knee arthroplasty although the benefit of postoperative wound drainage is controversial in the literature. This study questioned(More)
