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.

Skin Cysts Cysts are noncancerous, closed pockets of tissue that can be filled with fluid, pus, or other material. Cysts are common on the skin and can appear anywhere. They feel like large peas under the surface of the skin. Cysts can develop as a result of infection, clogging of sebaceous glands (oil glands), or around foreign bodies, such as earrings.
External cephalic version, or version, is a procedure used to turn a fetus from a breech position or side-lying (transverse) position into a head-down (vertex) position before labor begins. When successful, version makes it possible for you to try a vaginal birth.
Not every woman undergoes a traditional vaginal delivery with the birth of her child. Under conditions of fetal or maternal distress, or in the case of breech presentation (when a baby is turned feet first at the time of delivery), or if the woman’s first baby was born by cesarean delivery, a procedure called a cesarean section may be required. During a cesarean, a doctor will make either a lateral incision in the skin just above the pubic hair line, or a vertical incision below the navel. As the incision is made, blood vessels are cauterized to slow bleeding. After cutting through the skin, fat, and muscle of the abdomen, the membrane that covers the internal organs is opened, exposing the bladder and uterus. At this time the physician will generally insert his or her hands into the pelvis in order to determine the position of the baby and the placenta. Next, an incision is made into the uterus and any remaining fluids are suctioned from the uterus. The doctor then enlarges the incision with his or her fingers. The baby’s head is then grasped and gently pulled with the rest of its body from the mother’s uterus. Finally, the abdominal layers are sewn together in the reverse order that they were cut. The mother is allowed to recover for approximately three to five days in the hospital. She will also be quite sore and restricted from activity for the following several weeks. There are several potential complications associated with this procedure that should be discussed with a doctor prior to surgery.
A subdural hematoma (SDH) is a collection of blood below the inner layer of the dura but external to the brain and arachnoid membrane (see the images below). Subdural hematoma is the most common type of traumatic intracranial mass lesion. Subdural hematoma occurs not only in patients with severe head injury but also in patients with less severe head injuries, particularly those who are elderly or who are receiving anticoagulants. Subdural hematoma may also be spontaneous or caused by a procedure, such as a lumbar puncture (see Etiology). Rates of mortality and morbidity can be high, even with the best medical and neurosurgical care (see Prognosis). Subdural hematomas are usually characterized on the basis of their size and location and the amount of time elapsed since the inciting event age (ie, whether they are acute, subacute, or chronic). When the inciting event is unknown, the appearance of the hematoma on neuroimaging studies can help determine when the hematoma occurred. These factors, as well as the neurologic and medical condition of the patient, determine the course of treatment and may also influence the outcome. Generally, acute subdural hematomas are less than 72 hours old and are hyperdense compared with the brain on computed tomography scans. The subacute phase begins 3-7 days after acute injury. Chronic subdural hematomas develop over the course of weeks and are hypodense compared with the brain. However, subdural hematomas may be mixed in nature, such as when acute bleeding has occurred into a chronic subdural hematoma. Presentation varies widely in acute subdural hematoma (see Clinical). Many of these patients are comatose on admission. However, approximately 50% of patients with head injuries who require emergency neurosurgery present with head injuries that are classified as moderate or mild (Glasgow Coma Scale scores 9-13 and 14-15, respectively). Many of these patients harbor intracranial mass lesions. In a large series of patients who developed intracranial hematomas requiring emergent decompression, more than half had lucid intervals and were able to make conversation between the time of their injury and subsequent deterioration. In a more comprehensive review of the literature on the surgical treatment of acute subdural hematomas, lucid intervals were noted in up to 38% of cases. These patients may be more likely to benefit from medical and surgical intervention when instituted in a timely fashion (ie, before further neurological deterioration).
- elbow dislocations in children are a relatively uncommon; - peak incidence occurs in adolescence between 11-15 years. - posterior dislocations are most common type; - posterior dislocation usually results from fall on outstretched hand w/ forarm supinated & elbow extended or partially flexed; - coronoid process, which nl resists posterior displacement of ulna, is relatively small in children; - anterior capsule of elbow joint is torn by force of the impact transmitted upward thru the ulna and radius
IV cannulation is a skill that has scared a lot of student nurses and even professionals. Perhaps it’s because IV insertion is an invasive procedure, and nurses are too worried that they might hurt their patients. Or maybe it’s because they are just clueless about IV therapy do’s and don’ts–things that one can only fully understand through constant practice.

Paracentesis is a procedure to take out fluid that has collected in the belly (peritoneal fluid). This fluid buildup is called ascites camera.gif. Ascites may be caused by infection, inflammation, an injury, or other conditions, such as cirrhosis or cancer. The fluid is taken out using a long, thin needle put through the belly. The fluid is sent to a lab and studied to find the cause of the fluid buildup. Paracentesis also may be done to take the fluid out to relieve belly pressure or pain in people with cancer or cirrhosis.
Frontotemporal dementia is the name for a range of conditions in which cells in the frontal and temporal lobes of the brain are damaged. These lobes control behaviour, emotional responses and language. This means that people will experience changes in personality and behaviour, or may struggle with language – for example, in finding the right word. Frontotemporal dementia is a less common form of dementia which is more likely to affect younger people – those under 65.
