Clinical Trial
[Long-term efficacy and safety of balloon kyphoplasty for treatment of osteoporotic vertebral fractures].
The aim of the evaluation of treatment protocols was an extension of the documentation regarding efficacy, duration of action and safety of balloon kyphoplasty. In addition, the data analysis should be used to clarify whether differences arise concerning the treatment success, depending on the number and/or position of the augmented vertebral bodies. ⋯ Balloon kyphoplasty was proven to be a safe and effective procedure. Thus, the balloon kyphoplasty in carefully selected patients can yield better results than a non-invasive conservative treatment. It contributes decisively a better quality of life for the operated patients and diminishes the risks of long-lasting treatment with drugs.

Comparative Study
[Ultrasound as a viable alternative to standard X-rays for the diagnosis of distal forearm fractures in children].
Distal forearm fractures are very common in childhood. Radiography of the wrist is the standard diagnostic procedure. But because of higher sensitivity of growing bones to ionising radiation the diagnostic use of X-rays should be minimised as much as possible. Recent studies have shown that distal forearm fractures in children can be safely and reliably diagnosed using only ultrasound. The aim of our study was to evaluate and confirm the safety and applicability of the ultrasound diagnostic procedure in comparison to X-ray diagnosis under routine conditions of our paediatric emergency department. ⋯ We confirm ultrasound is an applicable, rapid and safe alternative to X-rays in diagnosing metaphyseal forearm fractures in children. Even sonographic axis measurement seems to be a viable method. Thereby ultrasound potentially reduces the X-ray burden in children and additionally accelerates the diagnostic procedure.

Controlled Clinical Trial
[Total knee arthroplasty in post-traumatic osteoarthritis].
This study aims to analyse the outcome and the complications after total knee arthroplasty in post-traumatic osteoarthritis in comparison to TKA in patients with degenerative osteoarthritis. ⋯ Patients after TKA because of post-traumatic osteoarthritis show worse results concerning function and condition compared to patients with degenerative osteoarthritis. Heterogeneous pathogenesis and high rates of revision operations underline the complexity of this group of patients. The treatment has to be adjusted to the patient's requirements as well to the pathoanatomy.

Minimally invasive procedures for additive ventral stabilisation of dorsal instrumented unstable burst fractures of the thoracolumbar spine have been developed. Typical complications of these standardised techniques have been described in the past. Only limited data exist on injury to upper abdominal organs associated with minimally invasive spondylodesis. ⋯ Retraction of the diaphragm might be the main factor causing this complication. In conclusion, splenic injury is a rare but potentially lethal complication in the operative treatment of thoracolumbar fractures. Therefore postoperative abdominal sonography should routinely be done and in case of haemodynamic instability the possibility of splenic injury must be considered as part of the differential diagnosis.
