Vascular spasms temporary limit blood flow to tissue supplied by that vessel. The most common symptom is pain. Other symptoms are caused by lack of proper circulation and will vary depending on the specific organ affected:
When the spasm affects circulation in a limb, there may be pallor and a sensation of cold in that arm or leg. Limb function and movement will be impaired.
When the spasm affects circulation in the heart, there may be symptoms similar to a heart attack and irregular heartbeats. Other names for chest pain resulting from vascular spasm are Prinzmetal's angina and variant angina.
Signs and tests
These vary depending on the affected organ.
Studies show muscle weakness after total knee replacement (TKR) is common months and even years after the surgery. This study compares the force produced during a single-leg press after TKR. Nine patients with TKR were compared to nine adults without TKR (the control group). This is the first study to measure force produced by the leg after TKR in a weight-bearing position. It's unique because force is examined across several joints using many muscle groups. This gives a better idea of what's going on in a fully weight-bearing position. Other studies have reported on forces in one joint at a time. Often only the knee extensor muscles are tested. The authors report that there is much less force through the leg with the joint replacement. These measures were lower when compared to the patient's healthy leg and when compared to the control group. This shows that the entire leg, not just one set of muscles, has less power. The researchers suggest that the loss of force in the leg with the TK...
Are you 55 years old or older and still pain free? Chances are you have osteoarthritis and don't know it. X-rays show arthritic changes in eight out of every 10 adults age 55 and older. Knees, hips, and spines are affected most, in that order. Older adults with leg pain may have arthritic changes in both the hip and spine. They sometimes have a total hip replacement (THR) only to develop groin and buttock pain next. Or suddenly they have muscle weakness that isn't related to the THR. In these cases, lumbar spinal stenosis (LSS) may be the problem. LSS occurs when age-related changes narrow the canal where the spinal cord and nerves travel. Bone spurs, thickened ligaments, and worn-down joints are just some of the changes leading to LSS. These doctors from Baylor College of Medicine offer other orthopedic surgeons some guidance. They say that when a patient with a recent THR has severe pain after the operation, look for infection, an unstable implant, or LSS. Location of the pain is a key...
