Arthritis Conditions and Prolems
Bursitis
A condition frequently confused with arthritis is bursitis. Bursitis means a painful inflammation of the bursa, which are small, fluid-filled sacs near joints between muscles, bones ligaments, and tendons. Their function is to reduce friction and help absorb shocks.
Bursitis differs from arthritis in that inflammation involves the areas surrounding the joint rather than the joint itself. There are many varieties of bursitis, many of which are known by popular names. For example, prepatellar bursitis, known as housemaid’s knees, is caused by prolonged kneeling on a hard surface, and frozen shoulder, which is the end result of an untreated form of bursitis of the shoulder.
Treatment for bursitis usually consists of anti-inflammatory medications and rest. Injections with steroids are helpful in some cases; physical therapy is also helpful. Application of an icepack may relieve pain for some individuals. In many cases, bursitis lasts only a short time.
In rare cases, a bursectomy -i.e., an operation to remove the bursa - may be performed.
Frozen Shoulder
Frozen shoulder technically known as pericapsulitis or adhesive capsulitis-causes general pain and tenderness as well as loss of motion. Frozen shoulder usually occurs after the age of 40 and often as a secondary problem after a fall or with another type of shoulder condition, diabetes, or inflammatory arthritis.
The conditions involves the adherence of the shoulder joint capsule to part of the neck, with the underarm muscles binding to themselves, causing a thickening and contraction or frozen feeling.
Diagnosis is made through arthrography, magnetic resonance imaging or MRI; or arthroscopy. Frozen shoulder is often treated in many different ways, including physical therapy, ice packs, ultrasound and gentle range of motion exercises, NSAIDs, corticosteroid injections, and surgery.
