Beginning with 3D correction principles introduced by Cotrel and Dubousset insurgical techniques are also aimed at correcting spinal deviations in all 3 planes. In contradiction with these, routine radiological diagnosis and current classification of scoliosis is almost exclusively rely on frontal and lateral X-ray images, missing the possibility to directly visualize and measure axial vertebral rotation.
Computer tomography CT permits a potentially more accurate analysis of axial vertebral rotation, but is limited to short spinal segments and requires a prohibitively high radiation dose, especially for CT 3D reconstructions. Pre- and postoperative EOS frontal and lateral images were aquired in a weight-bearing standing position within seconds followed by surface 3D reconstruction of vertebrae and pelvis osteoarthritis knee imaging a semiautomatic sterEOS 3D software employing automated edge detection, shape recognition algorithms and global statistical 3D models of vertebrae with deformable meshes, allowing construction of individually-specific osteoarthritis knee imaging models of the vertebral column of the Th1-LV segment.
Results: EOS 2D provides high-resolution, wide-dynamic range, bit grayscale digital images that match or surpass qualities of traditional digital X-rays, permitting accurate and reproducible detection of vertebral landmarks required for a precise 3D surface reconstruction of the spine.

EOS 3D surface reconstructions produce complex, full-detail, very realistic-looking images containing a significant amount of information. Horizontal plane images provide a unique insight into 3D osteoarthritis knee imaging deformities.
Automatically measured parameters provide a complete characterization of the spine in all 3 planes. Examination of planar projections of sterEOS 3D reconstructions afford possibilities to visualize scoliotic deformities in frontal, sagittal and very uniquely, horizontal planes, a feature unrivalled by other routine clinical diagnostic tools available for scoliosis.
A vertebra vector characterizes the position, 3D orientation and size of a vertebra at the same time, providing means for direct quantitative analysis in the Horizontal plane and a new definition of optimal surgical correction.
Apart from CT 3D that is rarely used in adolescent scoliosis diagnostics due to high radiation dose, the ability to visualize and analyze scoliotic deformities in 3D was not available in clinical practice. After our 1 year of clinical work in 3D spine imaging with this system, moving forward to quantify scoliotic deformities in Horizontal plane required a new approach that is based on our new concept of vertebra vector.
Methods: Pre- and postop EOS examinations, followed by semi-automatic 3D reconstruction of the spine were carried out in a representative case of a 16 years old girl with a right convex thoracic idiopathic adolescent scoliosis, treated according osteoarthritis knee imaging Cotrel-Dubousset technique using multi-anchors and rods.
Position of vector points for full-spine vertebrae were determined manually based on existing vertebral landmarks.

Vector coordinates A, B and vector angle α in the Horizontal plane were obtained after normalization based on built-in 3D calibration of EOS. Numerical values were calculated in a coordinate system consisting of the interacetabular line and the sagittal median axis using standard vector algebra.
Results: Pre- and postop values for Cobb angle, kyphosis, lordosis and axial rotation of apical vertebra, and vertebra vector parameters of full-spine were analised. Conclusion: Beyond the essential 3D imaging of név tabletták ízületi fájdalmakhoz geometry in scoliosis by EOS, visualization of vertebra vectors and comparison of their numerical values before and after surgery provides means for direct quantitative analysis in the Horizontal plane and a new definition of optimal surgical correction.
The ability to routinely visualize spinal deformities in 3D highlights the need for quantification of positional and rotational changes of vertebrae defining the scoliotic curve, especially in Horizontal plane.
Our new concept of vertebra vector provides the basis for this approach.

Frontal and sagittal spinal curves are conventionally measured by the Cobb's method. The feasibility of a new method using vertebra vectors for replacement of conventional Cobb's methods for the same purpose was evaluated in this study. Methods: patients were evaluated with radiologically confirmed diagnosis of idiopathic scoliosis who underwent surgical correction at our department in the period of Based on pre- and postop EOS examinations followed by 3D reconstructions, vertebra vectors were generated as presented earlier.
The method employing vertebra vectors was very osteoarthritis knee imaging to the original one with the following differences: in the frontal plane, instead of the endplates, angulation between the interpedicular line of the two end-vertebrae was calculated. In sagittal plane, instead of the angle between lines determined by endplates of Th4-Th12 and L1-L5, the angle between lines determined by corresponding osteoarthritis knee imaging vectors of the same two pairs of vertebrae was computed.
Results: Results of the comparisons showed no significant difference for the frontal plane angulations measurements. Kyphosis and especially lordosis values, however, differed significantly between the two methods.
Strong and significant correlation was found between any two of the corresponding values of the two methods. Conclusion: The vertebra vector-based method is completely suitable for angulation measurement in the frontal plane for characterization of scoliotic curves, yielding curve values identical to those measured by the traditional Cobb's method.
Disparity of sagittal angulation values is explained by the mildly wedged shape of vertebra Th12 and LV, and as a consequence, by a slight angle degrees between the lower and upper endplates of these vertebrae - while the vertebra vector is always parallel to the upper endplate of its corresponding vertebra, therefore this method always measures angulations between the upper endplates of any two vertebrae and this yields smaller kyphosis and lordosis angle values.

Discrepancies in lumbar lordosis values could osteoarthritis knee imaging overcome by a standard measurement between L1-S1 since the conventional method also measures angulation between L1-S1 vertebral upper endplates. Nevertheless, the method based on vertebra vectors still seems to provide more reliable measurement values overall because horizontal positioning of the vertebra vector inside the vertebra body at pedicular level is least prone to be affected by scoliotic osteoarthritis knee imaging changes like wedging and pedicular positioning is also more relevant for corrective surgery.
Significance: Conventional Cobb's methods for characterization of the spinal column in the frontal and sagittal plane could be preserved and readily applicable by angulations measurement methods using osteoarthritis knee imaging vectors.
By complementing vertebra vector-based osteoarthritis knee imaging of the spine in the horizontal plane with a complete frontal and sagittal characterization, our concept of vertebra vectors proves to exhibit an important practical value in a new 3D classification of scoliosis.
Restoring stability and securing of neurological structures is the goal of surgery in these cases. Since the upper cervical spine is crucial for mobility of head and shoulders, the purpose of the present study was to evaluate the individual importance of mobility and relief from pain. Methods This is a retrospective data- analysis of 21 patients with surgical treatment of the upper cervical ízületi fájdalom csakrák. Between October and October twenty- one patients 11 male, 10 female with a mean age at operation of 66 years median 68, range 82 years were treated for instability of the upper cervical spine.
The most frequent pathology was Rheumatoid Arthritis 10 casesfollowed by metastases 6 and trauma 5. Given that indications for surgery are based on dislocation and neurological symptoms, we wanted to point out specific features of the surgical technique e.
Results Twelve patients were still alive as of December with a maximum follow- up of 8. Nine patients died after a mean period of 1. Conclusion Specific information either for possibly affected patients e. There still exists no commonly accepted guideline referring surgical stabilization of the cervico- cranial- junction.
The reported results on outcome highlight relief from pain to be more essential than mobility and contribute to a post- symptomatic surgical treatment with a mean fusion length of 5 vertebral bodies C0 to C4. Besides the obtained results during surgery and immediate postoperative period up to 10 daysis analyzing the evolution of correction over a long time period more than 5 years. This method does not require prolonged hospitalization of the patient, mobilization is recommended immediately postoperative and the use of braces is not necessary.
It does not preclude other interventions on the spine or chest. The procedure supposes osteoarthritis knee imaging iatrogenic soft-tissue lesion, minimal blood loss, and is not time consuming. Materials or Subjects: In our Institution we have applied the cement discoplasty in open procedures since This technique is used to substitute the spacers in osteoporotic cases in order restore the weight bearing capacity of the anterior column of the spine.
We call it "custom made spacer", as it fills in the prepared intervertebral room individually and precizely. As the operations frequently lead to complications in theese elderly patients, we decided only dealind with the suspected maior element of their complaints, the emptied disc spaces. In patients, in case of whom spinal canal stenosis is absent and the known syptoms of vertical instability of the spine is present with vacuum in disc spaces, we decided to fill osteoarthritis knee imaging this gap percutaneously by PMMA.
Since We performed x-ray and CT examinations before and after the procedure Results: As the method described is new, we don't have long term results jet. The early experience however suggest, that aspecially in comparison with the large open operations, our percutaneous procedure gives good results - as an alternative.
As far we encountered no complications. Conclusions: Those patients, whom show no sign of stenosis of their lumbar spinal canal, but are unable to stand or walk, gain much better quality of life by percutaeously filling in the vacuum disc spaces and so getting back the weight bearing osteoarthritis knee imaging of their spine. Spinal deformities generally occur after immediate or potential instability caused by the initial trauma.
In both cases angular posttraumatic kyphosis PTK developes at the level of trauma. PTK is a frequent consequence of unrecognised or inadequately treated segmental instability, which could cause pain, progression of deformity, or neurological deficit.
Purpose: The aim of our study was to evaluate the surgical treatment for late posttraumatic spinal deformities, with the emphasis on importance of proper primary treatment. Methods: In the last 15 years 18 patients were treated surgically with posttraumatic deformity at our department average age In 14 cases surgery was performed because osteoarthritis knee imaging thoracolumbar angular PTK.
Within this group correctional surgery was needed in 5 cases after conservative treatment of a fracture considered stable, or because of inadequate internal fixation of 6 cases. Posterior stabilization was the way of treatment in the cases of PTK with less than 30 degrees angulation.
In the cases of PTK with more than 30 degrees angulation the anterior aproach was performed using osteoarthritis knee imaging bone graft for anterior column reconstruction, followed by osteoarthritis knee imaging stabilization. In cases of segmental instability without deformity, short posterior reconstruction has been carried out our 2nd group. Our third group was formed by those patients whose deformity was developed secondary as a consequence of muscle function deficiency due to paraplegia caused by primary trauma.
Surgical results were evaluated after an average of 3.
Results: In cases of PTK the average angulation was Preoperative neurological symptoms were diminished osteoarthritis knee imaging all cases. In the PTK group the pain was decreased significantly after the surgery, while completely disappeared in the second group. In all cases a significant progress was detected in the sagittal balance of the spine.
Conclusions: Final outcome of traumatic spinal disorders was determined by the neurological deficit and instability due to the osteoarthritis knee imaging trauma, and most importantly the quality of the primary care. The majority of trauma cases are generally treated correctly, but the remaining instability leads to severe deformity. For treatment of segmental instability without deformity the short posterior stabilization method is suggested. To achieve proper correction in the PTK group an expanded posterior fusion is indicated.
Depending on the magnitude of the angulation, an anterior liberalization and corpodesis might be crucial before posterior fusion.
In the case of instable paralytic scoliosis with neurological deficit a degrees fusion should be performed. Approximately 20, patients per year United States require treatment of symptoms related to spinal cord compression.
Securing of neurological structures and restoring stability osteoarthritis knee imaging the goal of surgery in these cases. Surgical treatment in cases of instability combined with symptomatic spinal cord compression reaches from dorsal decompression and stabilisation to anterior resection, interposition and dorsal stabilisation of the affected vertebra.
The purpose of the present study was to compare surgical techniques posterior vs. Methods Between February and April patients 62 male, 39 female with a mean age of 63 years range 82 years were treated for neurologically symptomatic spinal metastases. The most frequent site of metastasis was thoracic spine 62 osteoarthritis knee imaging by lumbar 23 and cervical spine Given that indications for surgery are based on neurological symptoms and instability, we wanted to osteoarthritis knee imaging changes in Frankel- Score to demonstrate differences between posterior and antero-posterior stabilization.
Arthritis or arthrosis - that is the question? An overview of concept in osteoarthritis.
Results Forty-three patients were still alive as of February with a maximum follow- up of 7. All other patients died after a mean period of Our data show good to excellent outcome based on Frankel- Score.
Conclusion Our data on outcome show restored motor function even among patients with poor prognosis who received solely decompression and posterior stabilization. Thus, patients with poor life expectancy should be limited to posterior stabilization.

Purpose Our aim was to review the findings in the cases of spondyloptosis we have treated and to determine the possible causes of progression by the help of their spinopelvic parameters.
Methods We have treated 7 patients with the diagnosis of spondyloptosis int he last 10 years 5 female, 2 male, average age was 16,57 years. In one case besides to spondyloptosis a severe thoracolumbar scoliosis was present, therefore a posterolateral spondylodesis was performed according to the Cotrel-Dubousset principle using titanium SCS implant system.
Radiological imaging was performed before and during the traction period, pre- and postoperatively, then spinopelvic parameters were determined.
Results The average LV reduction value was 15,35 mm, while osteoarthritis knee imaging average postoperative changes were the following: LI-LV lordosis 20,4 degrees, Th4-Th12 kyphosis 7,8 degrees, the pelvic incidence PI 11,3 degrees, the sacral slope SS 13,2 degrees and the pelvic tilt PT 8,04 degrees. The spinopelvic balance was assessed from the measurement of the aforementioned pelvic parameters.
At one patient the wedging of the LV gained 35 degrees, while the sacral plate was almost always hypoplastic and roundly shaped. Conclusions Sacral slope alone is not a predisposing factor leading to progression of spondylolisthesis into ptosis. The parameters are detectable before the development of spondyloptosis, therefore the expected progression could be predicted. Vertebroplasty and kyphoplasty are minimally invasive surgical procedures that are effective in patients with metastatic spine disease.
Untreated bone metastases can lead to loss of stability, pain, and fracture with the potential for myelon compression. We present a retrospective data analysis of 22 patients with spinal metastases.
