The aim of this study is to emphasize the effects of vertebroplasty from the clinical point of view and the influence on the adjacent joints. Materials and methods: Between 2009 and 2010 we conducted 9 vertebroplasty procedures the level of T12 to L3. To follow-up patients both before and after the surgery, besides the clinical examination, they were also taken spinal radiographs and MRI to examine the adjacent vertebras and the zygapophyseal joints and determine the adjacent vertebral bodies. The vertebroplasty was done by bipedicular approach using general anesthesia. the vertebroplasty procedures efficiently reduce pain; the vertebroplasty procedures do not reconstruct the size of the body of the vertebra; in case of important wedge fractures there can be a progression of the kyphotic angle as the vertebral joints are worn out and influence the intervertebral discs.

The aim of this study is to determine clinical and radiographs results in the treatment of unicompartmental gonarthrosis after medial tibial osteotomy with bone graft from the iliac crest associated with arthroscopy and knee débridement. Method: The study was performed in 19 patients treated with exploratory arthroscopy and articular débridement followed by medial opening tibial osteotomy in the proximal third with a bone graft stabilized with plate and screws or cramps. The pre and postoperative factors analyzed within this study are: age, KSS score, Alhback score, preoperative and postoperative knee varus and valgus alignment, ligament stability degree, immediate and late adverse events and patient satisfaction with the procedure. Conclusions: After investigations, we consider that high opening tibial osteotomy with bone graft from the iliac crest associated with débridement arthroscopy is an alternative in the treatment of the unicompartmental gonarthrosis, favoured by the precision of the arthroscopic diagnosis [ABSTRACT FROM AUTHOR]

The study asses the relations between the roots of the spinal nerves and the spinal pedicles at a thoracic level, as well as the importance of these relations in the transpedicular approach for vertebroplasty. Material and Method: the study was conducted on four adult human cadaver spines. We measured the distances between the superior and inferior pedicle with the nervous roots and the diameters of the spinal pedicles. Knowing these values allow a safe transpedicular approach, with reduced complications. Conclusions: The distance between the superior pedicle and the root of the spinal nerve presents no clear evolution of values in connection to the level of the vertebra. The distance between inferior pedicle and the nervous root shows a progressive reduction of the values in the craniocaudal direction. When referring to the transverse and sagittal diameter of the pedicles we observe a progressive growth in size of the thoracic pedicles from the level T4 to T12. The complications can be prevented when surgery techniques are respected and the surgeon is familiar with the Spinal Anatomy. [ABSTRACT FROM AUTHOR]

Background and Objectives: Osteoporotic spine fractures represent a significant factor for decreasing quality of life in the elderly female population. Understanding the mechanisms involved in producing these fractures can improve their prevention and treatment. This study presents a biomechanical method to produce a vertebral fracture, conducted on a human spine segment, observing the displacements and strains in the intervertebral disc, endplate, and vertebral body., Materials and Methods: We performed two tests, one corresponding to an extension loading, and the second to an axial loading., Results: The maximum displacement in the target vertebral body presented higher values in the case of the extension as compared to the axial strain where it mainly occurred after the fracture was produced. The strains occurred simultaneously on both discs. In the case of the axial strain, due to the occurrence of the fracture, the maximum value was recorded in the spine body, while in the case of the extensions, it occurred in the neural part of the upper disc. The advantage of this method was that the entire study was an experiment, using optical methods, increasing the precision of the material data input., Conclusions: The research method allowed recording in real time of a larger amount of data from the different components of the spine segment. If there was an extension component of the compression force at the moment of the initial loading, part of this load was absorbed by the posterior column with higher mechanical resistance. After the maximum capacity of the absorption was reached, in both situations the behavior was similar.
