Acromioclavicular Joint

Acromioclavicular Joint Space Widening

Degenerative change of this joint is primarily related to aging. The disease may start as early as the second decade of life, becoming severe by the fifth decade de Palma 1957 . The disease causes discomfort or pain that may be aggravated by motion, radiating to the upper arm. Radiography in the early stage shows mild cortical thickening and subcortical osteopenia in the para-articular bones, giving rise to a pencil-line appearance and apparent articular widening Fig. 9.22A . With the progress...

Increased Tracer Uptake Left Ischiam Enthesopathy

Axillary Pouch

Heel pad (Fig. 12.32A) is difficult if not associated with a bone change, whereas pinhole scin-tigraphy can specifically indicate their diagnosis by showing tracer uptake at the site in question even in the absence of radiographic change (Figs. 12.30B, 12.31B and 12.32B). Established plantar fasciitis always reveals a characteristic calcaneal spur (Fig. 12.33 A). MRI may demonstrate edema in acute tenosynovitis Fig. 12.30A, B Tenosynovitis of the flexor carpi ulnaris tendon. A Dorsoventral...

What Is Tracer Uptake Of The Knee

Staph Infection The Knee Pictures

Fig. 9.13A, B Multicompartmental involvement in osteoarthritis in the knee. A Anterior pinhole scan of the right knee in a 35-year-old man shows multiple, asymmetrical areas of segmental, spotty, and patchy tracer uptake in the femorotibial compartments including the tibial tubercles and the proximal tibiofibular joint arrows with narrowed articular space arrowheads . B Anteroposterior radiograph reveals minimal marginal osteophytes arrowheads , the pointing of the tibial tubercles middle...

Wrist and Carpal Joints

Cystic Change Carpal Bones Rheumatoid

The wrist radiocarpal joint is a biaxial and ellipsoid articulation formed between the distal end of the radius and the scaphoid, lunate, and triquetrum with triangular cartilage on the ul-nar side. The joint is lined by synovium and surrounded by fibrous capsule and radiocarpal ligaments. In addition, there are complex inter-carpal joints, interconnecting a the proximal carpal bones, b the distal carpal bones, and c the two carpal bone rows. Osteoarthritis of the wrist predominantly affects...

Degenerative Joint Diseases

Subcortical Cyst Knee

Osteoarthritis Degenerative joint diseases include osteoarthritis, osteoarthrosis, osteochondrosis and others, and are the most common joint disorders that gradually disable patients. These recently receive greater attention because of the unprecedented prolongation of life expectancy and the availability of efficient prosthetic therapy. The terms describing degenerative joint diseases are many and used more or less loosely and even interchangeably. Osteoarthritis and osteoarthosis designate...
