Fractures of the distal end of the radius should be treated on the same principles as other fractures involving joints. Displaced articular fractures require open reduction to allow anatomical reconstruction of both the radiocarpal and the radio-ulnar joints. For extra-articular fractures with severe comminution and shortening this enables the radial length(More)
Care pathways for elderly hip fracture patients are increasingly implemented but there has been only limited evaluation of their use. Our objective was to investigate the impact of such a care pathway on the use of healthcare resources and on patients’ outcomes. The prospective survey covered 493 hip fracture patients 65 years of age or older that were(More)
With the introduction of Locking Compression Plates (LCP), Minimally Invasive Plate Osteosynthesis (MIPO) has become widely used. The plates act as internal fixators in a bridging manner, thus resulting in secondary bone healing. We retrospectively evaluated the healing pattern and the clinical evolution of diaphyseal and distal tibial shaft fractures over(More)
OBJECTIVE To evaluate the long-term results of external fixation of distal radius fractures. METHODS A retrospective follow-up study (median follow-up, 5.3 years) of 49 patients with 50 distal radius fractures treated with an external fixator was carried out. An external fixator (Minifixator, Stratec Medical, Waldenburg, Switzerland) was used. The(More)
Outcome of complex distal radius fractures. Design: Retrospective clinical observation. Outcome assessment of a clinical series of patients with complex distal radius fractures treated according to a structured, stepwise treatment algorithm. 17 patients (average age 47 years) with mostly high-energy injuries, 16/17 articular fractures including concomitant(More)
In the present study the variation of the localisation and the course of the coronal suture (CS) was examined on the lateral skull X-ray. The study shows a variation of the localisation and course of the CS from the average position within +/−4 mm in 65–77% and extreme differences between minimum and maximum values between 16 and 21 mm. The CS has also a(More)
PURPOSE To determine the amount and distribution of forces transmitted across the human radioulnocarpal joint under physiologic conditions in vivo. We performed an in vitro validation of a specifically developed capacitive pressure-sensor device and an in vivo measurement of force transmission and pressure distribution at the radioulnocarpal joint in a(More)
Three different plating techniques were used on experimentally produced dorsally displaced distal radius fractures in cadavers and were tested in 4-point bending: a AO 3.5-mm T plate (group 1), two 2. 0-mm titanium plates 60 degrees to each other (group 2), and the AO pi plate (group 3). A metaphyseal defect was simulated by a dorsally open wedge osteotomy.(More)
Fractures of the distal end of the radius are the most common fractures in humans. The variants of type of fracture and associated injuries are numerous, depending on the mechanism of injury, the amount of energy absorbed and the quality of the bone. Treatment concepts evolve as our understanding of the physiopathology of this heterogeneous group of(More)
