These bones and joints let us use our hands in lots of different ways. The wrist must be extremely mobile to give our […] Introduction Doctors commonly diagnose a sprained wrist after a patient falls on an outstretched hand.

X-rays taken at the time of the injury […] Introduction Thumb arthritis may be surgically treated with a procedure called resection arthroplasty or sometimes called excision arthroplasty. The term excision means to take out. In this surgery, the surgeon takes out a small bone at the base of the thumb and fills in the space with a rolled up section of tendon. The soft […] Introduction A shoulder dislocation is a painful and disabling injury of the glenohumeral joint. Most dislocations are anterior (forward) but the shoulder can dislocate posteriorly (backwards). Inferior and posterolateral dislocations are possible but occur much less often. The specific type of dislocation is based on the position of the humeral head in relation to the […] Introduction The squeaky hinge gets the grease. In the same way, the joint that aches from osteoarthritis (OA) gets the attention. Since the knee works like a hinge joint, it makes sense that lubricating the joint might help people with knee osteoarthritis. Accordingly, a treatment called viscosupplementation has been used by doctors to restore lubrication […] Introduction Over the past 30 years, artificial knee replacement surgery has become increasingly common. Millions of people have gotten a new knee joint. The first time a joint is replaced with an artificial joint the operation is called a primary joint replacement. As people live longer and more people receive artificial joints, some of those […] Introduction A popliteal cyst, also called a Baker’s cyst, is a soft, often painless bump that develops on the back of the knee. A cyst is usually nothing more than a bag of fluid. These cysts occur most often when the knee is damaged due to arthritis, gout, injury, or inflammation in the lining of […] |
