Hemodialysis, also called dialysis, is the most common treatment for kidney failure. A dialysis machine is an artificial kidney which cleanses the blood. During dialysis, blood is drawn from the patient into the dialysis machine, circulated through the machine, and then returned to the patient. Two needles are inserted into the patient's bloodstream to allow this process to occur. Hemodialysis is normally performed three times a week and the purpose of vascular access is to provide reliable sites where the bloodstream can be easily accessed each time. There are three major types of vascular access: arteriovenous fistula, arteriovenous graft, and venous catheter. The great majority of vascular accesses are created in the arm, but they can also be created in the leg.
A nonsurgical method of treating a ganglion is to drain the fluid from (aspirate) the ganglion sac. Your doctor can do this in the office using the following procedure: The ganglion area is cleaned with an antiseptic solution. A local anesthetic is injected into the ganglion area to numb the area. When the area is numb, the ganglion sac is punctured with a sterile needle. The fluid is drawn out of the ganglion sac. The ganglion collapses. A bandage and, in some cases, a splint are used for a few days to limit movement and prevent the ganglion sac from filling again. Treating a ganglion by draining the fluid with a needle may not work because the ganglion sac remains intact and can fill again, causing the ganglion to return. For this reason, your doctor may puncture the sac with the needle 3 or 4 times so the sac will collapse completely. Even then, the ganglion is likely to come back.
A ganglion cyst is a tumor or swelling on top of a joint or the covering of a tendon (tissue that connects muscle to bone). It looks like a sac of liquid (cyst). Inside the cyst is a thick, sticky, clear, colorless, jellylike material. Depending on the size, cysts may feel firm or spongy.
Aim: To detail two different clinical protocols and case studies using mini-implant anchorage developed to respond to certain clinical conditions. Methods: Two clinical protocols are described to upright mesially tilted mandibular molars. In the first protocol, a single mini-implant is inserted distally to the molar to be uprighted, and an elastic traction chain is applied to the tooth. In the second clinical approach, two mini-implants are inserted mesially. A screw-suspended TMA sectional archwire is applied (Derton-Perini technique). Two cases, descriptive of the two different treatment protocols, are described. In the first case, the mandibular right second premolar was missing and the adjacent first molar needed to be uprighted. A single screw was inserted distally to the first molar, and an elastic chain was applied. In the second case, the mandibular left second molar was missing and the third molar needed to be uprighted. Two mini-implants were inserted mesially and a fully screw-supported sectional archwire was used to upright and bodily mesialize the third molar. Results: Both uprighting approaches uprighted the molar axis without loss of anchorage. Conclusion: The two approaches to mandibular molar uprighting, developed as rational responses to different clinical cases, were both found to be effective.

The da Vinci® Surgical System provides surgeons with an alternative to both traditional open surgery and conventional laparoscopy, putting a surgeon's hands at the controls of a state-of-the-art robotic platform. Our surgeons can perform even the most complex and delicate procedures through very small incisions with unmatched precision.
Every year, thousands of conventional total shoulder replacements are successfully done in the United States for patients with shoulder arthritis. This type of surgery, however, is not as beneficial for patients with large rotator cuff tears who have developed a complex type of shoulder arthritis called "cuff tear arthropathy." For these patients, conventional total shoulder replacement may result in pain and limited motion, and reverse total shoulder replacement is a better option.
A spinal tumor is a growth that develops within your spinal canal or within the bones of your spine. It may be cancerous or noncancerous. Tumors that affect the bones of the spine (vertebrae) are known as vertebral tumors. Tumors that begin within the spinal cord itself are called spinal cord tumors. There are two main types of tumors that may affect the spinal cord: Intramedullary tumors begin in the cells within the spinal cord itself, such as astrocytomas or ependymomas. Extramedullary tumors develop within the supporting network of cells around the spinal cord. Although they don't begin within the spinal cord itself, these types of tumors may affect spinal cord function by causing spinal cord compression and other problems. Examples of extramedullary tumors that can affect the spinal cord include schwannomas, meningiomas and neurofibromas.
Reconstructive surgery is performed to treat structures of the body affected aesthetically or functionally by congenital defects, developmental abnormalities, trauma, infection, tumors or disease. It is generally done to improve function and ability, but may also be performed to achieve a more typical appearance of the affected structure. Reconstructive surgery is generally covered by most health insurance policies, although coverage for specific procedures and levels of coverage may vary greatly.
