The majority of traumatic vertebral fractures occur at the thoracolumbar junction and the lumbar spine and less commonly at the mid-thoracic and upper thoracic spine. In accordance, a high number of articles are dealing with thoracolumbar fractures focusing on the thoracolumbar junction. Nonetheless, the biomechanics of the thoracic spine differ from the thoracolumbar junction and the lumbar vertebral spine. ⋯ Generally, concomitant thoracic injuries are frequently seen in patients with thoracic spine fractures. Particularly sternal fractures cause an increase in fracture instability. In case of doubt, long segment stabilization is recommended in patients with unstable mid- und upper thoracic fractures, particularly in those patients with a high grade of instability.

Isolated pelvic fractures are relatively rare with an incidence of 3 - 6% of all fractures, but their incidence in polytraumatized individuals increases to 25%. The S3 guideline Polytrauma gives a clear recommendation for diagnostics by means of pelvic radiography (X-ray) and computed tomography (CT). A recommendation for the diagnosis by means of magnetic resonance tomography (MRI) especially in patients with low energetic/missing trauma does not currently exist. It is unclear on the basis of which criteria the MRI can be indicated in pelvic fractures. The aim of our study was therefore to retrospectively record indications for the indication of MRI in pelvic fractures - with adequate as well as inadequate trauma. ⋯ Pelvic fracture MRI should be performed primarily in elderly female patients without adequate trauma. In patients with adequate trauma, MRI is of low value, especially as MRI diagnostics are performed with delay, resulting in later surgery.

Magnetic resonance and computed tomography (MRI, CT) has been known to compare the sensitivity for the detection of pelvic fractures with others. It is unclear whether MRI imaging beyond CT leads to therapy change. The aim of our study is to determine the information gained from MRI in the diagnosis of pelvic fractures and to reduce the effects on the form of therapy. ⋯ In summary, it can be stated that the MRI in our study provided an information gain in the case of adequate and inadequate pelvic fractures as well as their accompanying injuries and that a possible therapeutic relevance of this information gain could be obtained specially at the inadequate fractures showed.

Randomized Controlled Trial
Intramedullary Nailing and Minimally Invasive Percutaneous Plate Osteosynthesis in Treatment of Displaced Clavicular Mid-shaft Fractures: A Prospective Study.
To compare the difference between MIPO and IMN methods in the treatment of displaced clavicular mid-shaft fractures. ⋯ Both methods were effective for the treatment of displaced clavicular mid-shaft fractures. However, the MIPO method might be better for recovery of shoulder and upper extremity function in the short term and might have a lower nonunion rate.

When using mobile 3D C-arms, impairments in image quality occur due to artefacts caused by metal implants as well as to the limited field of view. To avoid these restrictions, special computed tomography devices were designed, in order to improve image quality and to meet requirements for intraoperative usage. ⋯ Use of intraoperative CT was reliable and helpful. Integration in OR standards requires more effort than mobile 3D C-arms. Image quality was outstanding for intraoperative conditions and allowed proper assessment of implant placement and reduction in all cases. Due to the high financial outlay of the system and the good image quality of 3D C-arms in the extremities, we assume that this procedure can be applied in intraoperative CT in traumatological cases in spinal and pelvic surgery in high-level trauma centres.
