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.

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.

Due to the aging population, we are confronted with a growing number of osteoporotic and insufficiency fractures of the pelvic ring. They are the result of a low-energy trauma. With conventional X-rays, it is not always possible to identify the lesions. ⋯ The choice of treatment is determined by the degree and the localization of the instability. Osteosynthesis techniques differ from the techniques we use in adults. The trans-sacral positioning bar, iliolumbar fixation and angle stable plate osteosynthesis are used increasingly often.
