When the hematocrit rises to 60 or 70%, which it often does in polycythemia, the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels is greatly retarded because of increased resistance to flow. This will lead to decreased oxygen delivery.

A cataract is a cloudiness of the normally transparent lens that is situated behind the iris. The lens focuses light rays on the retina at the back of the eye to produce a sharp image of what we see.

Spina bifida is a condition that affects the spine and is usually apparent at birth. It is a type of neural tube defect (NTD). Spina bifida can happen anywhere along the spine if the neural tube does not close all the way. When the neural tube doesn’t close all the way, the backbone that protects the spinal cord doesn’t form and close as it should. This often results in damage to the spinal cord and nerves. Spina bifida might cause physical and intellectual disabilities that range from mild to severe. The severity depends on: The size and location of the opening in the spine. Whether part of the spinal cord and nerves are affected.

TAA is performed either under general anesthetic or nerve block. A tourniquet is used at the time of surgery to control bleeding and improve visualization during the surgery. The ankle is approached from the front or the side depending on the type of implant being used. Bone is then cut, allowing for placement of the metal and plastic components that re-create the ankle joint. Sometimes the patient will have a tight calf muscle or tight Achilles tendon that needs to be lengthened to improve range of motion of the ankle. The wounds are then closed using stitches or staples, and a splint is applied. A period of non-weightbearing in either a cast or cast boot is necessary to allow the implants to heal in place.
