Osteoarthritis is a common and debilitating joint disease that affects up to 30 million Americans, leading to significant disability, reduction in quality of life, and costing the United States tens of billions of dollars annually. Classically, osteoarthritis has been characterized as a degenerative, wear-and-tear disease, but recent research has identified it as an immunopathological disease o...

Eighteen transtrochanteric rotational osteotomies have been performed in 17 patients for femoral head osteonecrosis (15 patients, Ficat Stage III disease; three patients, Ficat Stage IV disease) during a 51-month period and have 18 to 63 months of follow-up study. The best results were in the posttraumatic and nonsteroid-associated idiopathic cases in patients with small necrotic segments in th...

ARTHRITIS, while not limited to cattle, has been recognized in this species since the beginning of veterinary history (4). Despite this long-standing recognition and the fact that arthritis presents definite clinical symptoms and lesions of diagnostic, prognostic, and pathological importance, surprisingly few studies delving into the cause and pathology of this important disease process in catt...

A rotator cuff tear causes shoulder pain and limits movement of the shoulder joint. A chronic degenerative change or impingement is the reason for a rotator cuff tear. Diagnosis is made based on medical history and, physical and radiological examinations. Other causes of shoulder pain include calcific tendinitis, degenerative arthropathy, joint dislocation, fracture, and primary or metastatic n...

In vivo proton (1H) magnetic resonance spectroscopy (MRS) has not yet been systematically used to study joint fluids in human knees. The objective of this study, therefore, was to assess the ability of proton MRS to identify the apparent heterogeneous characteristics of metabolic spectra in the joint fluid regions in human knees using a high-field MRI system. Eighty-four patients with effusion ...

Osteoporosis has become a major medical problem as the aged population of the world rapidly grows. Osteoporosis predisposes patients to fracture, progressive spinal deformities, and stenosis, and is subject to be a major concern before performing spine surgery, especially with bone fusions and instrumentation. Osteoporosis has often been considered a contraindication for spinal surgery, while i...

Cameron, H. U. and Fornasier, V. L. (1974). Thorax, 29, 472-474. The manubriosternal joint-an anatomicoradiological survey. The movement of the manubriosternal joint is said to be a significant factor in respiration. The incidence of fusion of the manubriosternal joint in necropsy cases has been investigated with fine detail radiography. In over 600 cases, fusion of the joint was found in 14% a...

Introduction The incidence of degenerative osteoarthritis of the hip or knee joint and degenerative changes in the lumbar spine both increased with age. It was reported that lumbar lordosis and sacral inclination were related to the degree of extension of the hip, there may be an associated loss of lumbar lordosis. Many patients also have degenerative changes of the knee with loss of extension ...
