Distal radius fracture are common injuries but no gold standard for their therapy exists. The aim of this study was to evaluate the quality of fracture care in distal radius fractures using an intramedullary implant (Targon DR interlocking nail). The nail had been developed to minimize the surgical exposure, increase fixation strength, to prevent tendon irritations and to allow for a fast return to activity. ⋯ In geriatric patients intramedullary interlocking nailing of displaced extraarticular or intraarticular distal radius fracture with the Targon DR nail represents a viable treatment option and alternative to the use of volar interlocking plating in terms of fracture reduction, maintenance of reduction and functional outcome.

Syndesmotic disruption may be difficult to reduce and fix, and malreduction is associated with inferior outcomes. Intraoperative computed tomography (CT) can provide accurate assessment of syndesmotic reduction. We hypothesized that three-dimensional (3-D) computer-assisted orthopaedic surgery (CAOS) with navigation of syndesmotic reduction could avoid malreduction. Our goal was to assess feasibility and accuracy of such a technic in a cadaveric study. ⋯ In this cadaveric study, CAOS with navigation allowed for very accurate syndesmosis reduction. This appears to be a promising technique to be confirmed by clinical study.

The name of Ender is primarily associated with the Ender nails, which were popular for trochanteric fracture fixation more than thirty years ago. However, Ender's concepts were not limited to the implant. ⋯ While Ender's nails have become history in the meantime, his principles of fracture reduction can be readily applied on surgery with modern implants such as proximal femoral nails. This article reflects the classification and the principles published by Hans Georg Ender in some print work hardly available nowadays.

To analyze knowledge of the anatomic location of the piriform fossa using a questionnaire with anatomic figures. ⋯ The low rate of correct answers indicates a tendency for the respondents to be influenced by illustrations in text books or examples in scientific publications that indicate the site of the piriform fossa incorrectly. Interest in the specialty of traumatology is possibly the reason why the subset of 4th-year residents had a better- than-average rate of correct answers.

The degree of femoral neck collapse that occurred after 519 patients with an intracapsular hip fracture treated by internal fixation with a Targon FN implant was measured. Mean femoral neck collapse was 8.0mm and this was increased for displaced fractures in comparison to undisplaced fractures (9.5mm versus 5.9mm, p<0.0001) and for those patients that subsequently developed fracture healing complications (11.6mm versus 7.1mm, p<0.0001). ⋯ This study confirms previous smaller studies that excessive femoral neck collapse (of more than 15mm) is more common for displaced fractures and presents new data to demonstrate that excessive femoral neck collapse is associated with an increased risk of fracture healing complications and increased loss of function. Future studies are now justified that consider methods to reduce fracture collapse.
