There was a significant increase in segmental contribution ratio of C3/4 (P=0.048), while a significant decrease in contribution ratio of C5/6 (P=0.037) was observed in the patients with herniated disc.

This may not be the case in segmental fractures, or when severe comminution is present. Reaming must be performed one or two increments beyond the planned nail diameter in order to allow a smooth nail insertion. For example, for a nail diameter of 10 mm, drill bits of up to 10.5 or 11 mm diameter are used. If a very tight fit of the reamer can ...

The clinical examination of a typical patient with thoracic scoliosis can reveal the nature of the coronal plane deviation along the curve(s), the hypokyphosis or apical lordosis in the sagittal plane, and the axial plane rotation present along the apex of the curve, as seen by an elevation of the ribs along the convexity and a relative depression of the ribs along the concavity ().

Jul 28, 2011· The method of using segmental pedicle screw fixation in scoliosis surgery was presented by Suk in 1994 [].Recently a quantitative study showed that rod derotation and direct vertebral derotation can significantly improve the 3-dimensional correction of scoliotic deformity [].Besides lateral curvature of vertebral column in the coronal plane, scoliotic deformities also include changes in the ...

In differential geometry, the Frenet–Serret formulas describe the kinematic properties of a particle moving along a continuous, differentiable curve in three-dimensional Euclidean space ℝ 3, or the geometric properties of the curve itself irrespective of any motion.More specifically, the formulas describe the derivatives of the so-called tangent, normal, and binormal unit vectors in terms ...

identify large segmental arteries or veins across the disc space that may represent a surgical bleeding risk. Contraindications for ACR are shared with any lateral trans-psoas approach. These include a history of retroperitoneal sur-gery, presence of scar tissue on this region, and evidence of fusion across the disc space (Figure 4).

But the sagittal plane is de-termined by the segmental mould and the superposition of the mouldings. In additional it is the lack of support at the sterno-clavicular level and at the abdominal level that avoids lumbar delordosis and thoracic flat back. In this study, early results of 148 first consecutive
