[Assessment of Reduction Abilities of an Expandable Stent in Treating Osteoporosis-Related Fractures of Th/L (Thoracolumbar) Spine].

PURPOSE OF THE STUDY The method of stabilising the osteoporosis-related spinal fractures using an expandable stent (vertebral body stent - VBS) and bone cement is generally accepted for its minimal invasiveness, a low risk of complications and confirmed analgesic effect. The efficiency of reduction of a compressed vertebra is, however, still discussed in the literature. Our hypothesis was that the stent expansion in the vertebral body can achieve a statistically significant reduction in the anterior, middle and posterior part of the vertebra.

Percutaneous versus open pedicle screw fixation for treatment of type A thoracolumbar fractures.

Background: The purpose of this study was to evaluate the effectiveness between percutaneous and open pedicle screw fixation without fusion for treating type A3 and A4 thoracolumbar fractures. Traumatic thoracolumbar burst fracture is a common pathology without a consensus on the best treatment approach. Percutaneous pedicle screw fixation (PPSF) systems have been recently introduced in the treatment of spinal fractures to reduce the adverse effects associated with the conventional open approaches, such as iatrogenic muscle denervation and pain.

[Management of Odontoid Fractures with Compression Screw and Anterior Transarticular Screw Fixation in Elderly Patients].

PURPOSE OF THE STUDY In the management of dens axis fractures in patients older than 65 years of age the posterior approach is preferred due to osteoporosis and the risk of a failure of anterior osteosynthesis. The posterior approach, however, is associated with a higher incidence of complications. A combination of anterior transarticular fixation of C1/2 (ATS) with compression osteosynthesis of dens axis significantly increases the stability of osteosynthesis.
