Definition Sciatica refers to pain, weakness, numbness, or tingling in the leg. It is caused by injury to or compression of the sciatic nerve. Sciatica is a symptom of another medical problem, not a medical condition on its own. Alternative Names Neuropathy - sciatic nerve; Sciatic nerve dysfunction Causes, incidence, and risk factors Sciatica occurs when there is pressure or damage to the sciatic nerve. This nerve starts in the spine and runs down the back of each leg. This nerve controls the muscles of the back of the knee and lower leg and provides sensation to the back of the thigh, part of the lower leg, and the sole of the foot. Common causes of sciatica include: Piriformis syndrome (a pain disorder involving the narrow piriformis muscle in the buttocks) Slipped disk Degenerative disk disease Spinal stenosis Pelvic injury or fracture Tumors
More and more studies show that controlling patients' pain and getting them moving after a total knee replacement (TKR) gives the best results. Doctors are looking for ways to do this. Managing patient's pain in the first 24 hours after surgery seems to be an important key. Better pain control is gained by giving the patient general anesthesia along with a local nerve block at the time of surgery. One of the nerves often blocked is the femoral nerve, which forms from nerve roots in the low back and runs down the front of the thigh. Blocks are also done to the sciatic nerve. The sciatic nerve is a major nerve that goes down the back of the thigh to the lower leg and foot. This study compared a femoral nerve block alone to a "double block" of the femoral nerve and the sciatic nerve. Pain levels and amount of opiate used were measured every four hours for the first 24 hours. The authors found that patients receiving the double blocks used less pain medication after TKR than those getting ju...
Sciatica is pain that radiates along the path of the sciatic nerve and it's branches. Your sciatic nerve is the longest nerve in your body. It runs from your spinal cord to your buttock and hip area and down the back of each leg.
Sciatica is a symptom not a disorder. The pain associated with sciatica signals another problem involving the nerve, the most common being a herniated disc. Another common cause of sciatica is called periformis syndrome. The piriformis muscle extends from the side of the sacrum to the top of the thighbones at the hip joint and passes over the sciatic nerve. When a tight or short piriformis muscle is stretched it can compress and irritate the sciatic nerve. This can happen to athletes who overuse and stretch the piriformis. Other causes of piriformis syndrome are habitually standing with toes turned out, over use without proper warm up, prolonged sitting and obesity. It can also be caused by an injury or in many cases it develops from general wear and tear on ...
