Paget disease, characterized by excessive and abnormal remodeling of bone, is a common disorder in middle-aged and elderly patients. The excessive remodeling gives rise to bones that are extensively vascularized, weak, enlarged, and deformed with subsequent complications.

The insertion of any implant or prosthesis into bone usually changes the biomechanical environment and, thus, alters the stresses and strains applied to the bone. Both bone overload and excessive stress protection can result in bone resorption. The material and geometry of any implant should be designed to avoid excessive...

Wheeless Textbook of Orthopaedics Discussion: - known risk factors include notching of the femur, osteoporosis, and excessive polyethylene wear (w/ subsequent osteolytic defect) - Radiographs: - often oblique radiographs are needs as well as AP and Lateral views, due to the rotation of the distal fragment; ...

Hyperhidrosis, or excessive sweating, can be localized to one area or it may be generalized. In the localized type, the most common sites are the palms and soles of the feet.

- chondromalacia describes softening & fissuring of articular hyaline cartilage;
- chondromalacia may result from an excessive load on patellofemoral joint, but disuse may be a contributing factor;
- most common in young women;

The word osteoporosis literally means "porous bones." It occurs when bones lose an excessive amount of their protein and mineral content, particularly calcium. Over time, bone mass, and therefore bone strength, is decreased. As a result, bones become fragile and break easily. Even a sneeze or a sudden movement may...

Necrotizing Fasciitis from Wounds Posted 11/25/2002 Jennifer T. Trent, MD, Robert S. Kirsner, MD Abstract Necrotizing fasciitis (NF) is a rare, life-threatening infection resulting in necrosis of the skin, subcutaneous tissue, and fascia. Mortality rates have been noted as high as 73 percent. Certain conditions can predispose patients to NF, such as diabetes mellitus, immunosuppressive...

a disorder which is caused by excessive production of parathyroid hormone which leads to hypercalcemia, recurrent nephrolithiasis, pancreatitis, peptic ulcers, and mental changes; - incidence of approx 5 /10,000 pts per year; ...

When excessive stress is placed upon the ball of the foot, a hairline break (fracture) of a long metatarsal bone may occur. This occurs most frequently to the second, third, or fourth metatarsal but can occur in any bone.

Contributor: Sara Buckelew, medical student Paget Disease of Bone Factoid 1288 - Created: 2001-03-07 09:15:37-05 - Modified: 2001-03-14 17:01:08-05 ACR Codes: 4.84 Paget disease of bone involves localized, uncontrolled formation of highly active osteoclasts. Initial bone resorption is followed by an intense increase in osteoblastic activity. The bone that...

Because of the anatomic positioning of the ulnar nerve, it is subject to entrapment and injury by a wide variety of causes. It is the second most common entrapment neuropathy in the upper extremity (the first being the median nerve and its branches). Because of its superficial position at the...

Neurofibromatosis in children: the role of the orthopaedist Crawford and Schorry J Am Acad Orthop Surg.1999; 7: 217-230
Abstract - Type 1 neurofibromatosis (NF-1), also known as von Recklinghausen disease, is one of the most common human single-gene disorders, affecting at least 1 million persons throughout the world. It encompasses...

When excessive stress is placed upon the ball of the foot, a hairline break (fracture) of a long metatarsal bone may occur. This occurs most frequently to the second, third, or fourth metatarsal but can occur in any bone.

Description: A monostotic form of fibrous dysplasia of bone. Constitutional, benign disease of the bones characterised by excessive proliferation of single or multiple circumscribed fibrous lesions, predominantly in the long bones, which predispose to painful bone deformities and pathological fractures, limping, unequal limp length, skull asymmetry, leontiaslike appearance, scoliosis, lordosis, and...

Multidirectional instability (MDI) is a relatively common, generally bilateral, atraumatic condition affecting shoulder function. MDI is caused by generalized capsular laxity—that is, insufficiency of the static ligament constraints. There is excessive mobility of the glenohumeral joint in all directions, although there may be a predominance of 1 direction, typically anteroinferior...

Bursae are saclike structures between skin and bone or between tendons, ligaments, and bone. They are lined by synovial tissue, which produces fluid that lubricates and reduces friction between these structures. Bursitis occurs when the synovial lining becomes thickened and produces excessive fluid, leading to localized swelling and pain.
Synonyms and...
