Once the serum ferritin and transferrin saturation are within the normal range, treatments may be scheduled every two to three months depending upon the rate of reabsorption of iron. A phlebotomy session typically draws between 450 and 500 mL of blood. The blood drawn is sometimes donated. Diet
A diet low in iron is generally recommended, but has little effect compared to venesection. The human diet contains iron in two forms: heme iron and non-heme iron. Heme iron is the most easily absorbed form of iron. People with iron overload may be advised to avoid food that are high in heme iron. Highest in heme iron is red meat such as beef, venison, lamb, buffalo, and fish such as bluefin tuna. A strict low-iron diet is usually not necessary. Non-heme iron is not as easily absorbed in the human system and is found in plant-based foods such as grains, beans, vegetables, fruits, nuts, and seeds. Medication
Medication: For those unable to tolerate routine blood draws, there are chelating agents available for use. The drug deferoxamine binds with iron in the bloodstream and enhances its elimination in urine and faeces. Typical treatment for chronic iron overload requires subcutaneous injection over a period of 8–12 hours daily. Two newer iron-chelating drugs that are licensed for use in patients receiving regular blood transfusions to treat thalassaemia (and, thus, who develop iron overload as a result) are deferasirox and deferiprone. Chelating polymers
A minimally invasive approach to hereditary haemochromatosis treatment is the maintenance therapy with polymeric chelators.
They increase in sagittal width from 9 mm to up to 18 mm at L5. They increase in angulation in the axial plane from 10 degrees to 20 degrees by L5. The pedicle is sometimes used as a portal of entrance into the vertebral body for fixation with pedicle screws or for placement of bone cement as with kyphoplasty or vertebroplasty. The laminae are broad, short, and strong. They form the posterior portion of the vertebral arch. In the upper lumbar region the lamina are taller than wide but in the lower lumbar vertebra the lamina are wider than tall. The lamina connects the spinous process to the pedicles. The vertebral foramen within the arch is triangular, larger than the thoracic vertebrae, but smaller than in the cervical vertebrae. Processes
The spinous process is thick, broad, and somewhat quadrilateral; it projects backward and ends in a rough, uneven border, thickest below where it is occasionally notched.The superior and inferior articular processes are well-defined, projecting respectively upward and downward from the junctions of pedicles and laminae. The facets on the superior processes are concave, and look backward and medialward; those on the inferior are convex, and are directed forward and lateralward. The former are wider apart than the latter since in the articulated column, the inferior articular processes are embraced by the superior processes of the subjacent vertebra.The transverse processes are long and slender. They are horizontal in the upper three lumbar vertebrae and incline a little upward in the lower two.
