PURPOSE Traditional surgical techniques for radiolunate arthrodesis typically result in an unsatisfactory primary stability. Thus cast immobilisation is implemented until bone healing is complete. Nonunion and implant dislocation are frequent complications. METHODS Eighteen patients (20 wrists) with rheumatoid disease who had undergone a radiolunate(More)
PURPOSE Vertebral osteomyelitis (VO) is an infection of the vertebral body and the adjacent disc space. The aim of our study was to identify outcome-related co-factors of patients with VO treated in the last decade. METHODS AND RESULTS We retrospectively identified 105 patients with VO (mean age 66.1 years) who had been treated at our institution from(More)
Rotational malalignment after intramedullary nailing of femoral fractures is common, and symptoms occur when malrotation reaches 15 degrees . Intraoperative measurement of rotation remains difficult, and multiple techniques have been described to address this. Regardless of the method used, rotational toggling may occur between the interlocking screws and(More)
Robot assisted fracture reduction of femoral shaft fractures provides precise alignment while reducing the amount of intraoperative imaging. The connection between the robot and the fracture fragment should allow conventional intramedullary nailing, be minimally invasive and provide interim fracture stability. In our study we tested three different(More)
The main problems in intra-medullary nailing of femoral shaft-fractures are leg-length discrepancies and rotational differences with an incidence of 2-18% and 20-40% respectively. These may lead to severe postoperative sequelae such as additional correctional operations and difficult rehabilitation. Insufficient visualization can be considered the main(More)
The preferred treatment of femoral (thigh bone) shaft fractures nowadays is the minimally invasive technique of intramedullary nailing. However, in addition to its advantages, this technique also has a number of disadvantages, such as the frequent occurrence of malaligned fracture reductions and high X-ray exposure, especially to the operating team. The aim(More)
The purpose of this prospective randomized comparative biomechanical study on four pairs of human cadaveric forearms was to discern whether primary stability following plate arthrodesis differs from the position of the screws. Four wrists were randomly assigned to either group such that one wrist of each pair was fixed via parallel screws and the other via(More)
Die Marknagelung ist ein Standardverfahren bei der Versorgung von Femurschaftfrakturen. Ein bisher ungelöstes Problem stellt die hohe Inzidenz der Torsionsfehler dar. Trotz dieser Kenntnis und intraoperativer Vorsicht scheint das Problem nur unbefriedigend gelöst zu sein. Ziel der Arbeit war, die mechanischen Einflüsse des Marknagels während und nach der(More)
