Fibrous dysplasia is the most common bone abnormality that occurs during the years of growth and development (as opposed to osteoporosis, the most common bone abnormality during the years of our bodies' decline). Dysplasia means abnormal development. Fibrous dysplasia is a disease of the bone in which the outer layers...

Osteonecrosis (ON) of the femoral head causes the bone to deteriorate, buckle, and collapse. As the vasculature is reportedly uniform in the femoral head, one would expect uniform susceptibility to ON; however, collapse typically occurs in the anterior region. We asked whether regional variations in bone quantity and/or quality could...

Bone is the second most commonly transplanted tissue after blood transfusions. In the US, there are more than 500,000 bone grafting procedures each year.
Osteogenesis, osteoinduction and osteoconduction are three properties in which a bone graft may possess. Osteogenesis is the process of new bone formation by cells from the host...

Patient Support Site for Fibrous Dysplasia What is Fibrous Dysplasia Fibrous dysplasia is a chronic condition of the skeleton where a portion of a bone develops abnormally. The condition begins before birth. It is caused by a gene mutation that affects the cells that produce bone. The mutation causes the cells...

Description Fibrous dysplasia is a chronic condition of the skeleton where a portion of a bone develops abnormally. The condition begins before birth. It is caused by a gene mutation that affects the cells that produce bone. The mutation causes the cells to form an abnormal type of fibrous bone... Highly Reputable

Because the initial fixation of an uncemented stem may be compromised in patients with osteoporotic bone (Class C, Dorr et al.), many surgeons prefer a cemented stem in this setting. We therefore determined the survival of an uncemented, proximally porous-coated, straight-stemmed, titanium alloy femoral component in patients with Class C...

A unicameral bone cyst (UBC) is a common benign fluid-filled lesion found almost exclusively in children. Much has been written about the diagnosis and management of these lesions, and evidence of a variety of successful treatment strategies can be found in the literature. The orthopedic entity called a UBC is not...

During childhood, the long bones (in the arms, legs, and back) grow at the ends of the bones, whereas the flat bones (such as the skull) have a different pattern of growth. Adult bone actually continues to expand, although very slowly. Bone also continually undergoes remodeling, replacing old bone with...

Sclerotic metastases are easily identified on the plain film, except when their density is interpreted as other overlying structures or pathology, perhaps osteoarthrosis. The microscopy of affected bone usually shows a proliferative bone reaction to the spread of tumour over the bone trabeculae. This results in the visible diffuse sclerosis...

In developing countries, chronic osteomyelitis often results from untreated acute hematogenous osteomyelitis but may also be seen as sequelae of trauma (war injuries). This condition is characterized by areas of devitalized bone/soft tissue (sequestra), which serve as a nidus for recurrent episodes of infection. The periosteal response (involucrum) serves to...

Bone morphogenic proteins (BMPs) are potent osteoinductive agents. Their use in fracture surgery is still being studied and the clinical indications are evolving. Heterotopic bone after BMP use in spine surgery is a known complication. While some literature describes the ability of BMP to enhance fracture healing, few articles describe...

General Discussion Fibrous dysplasia is a term that refers to either a group of chronic conditions featuring cystic bone growth that may arise from abnormal bone development or to a disease of bone marrow (medullary bone) characterized by benign cysts. Fibrous dysplasia is characterized by uneven growth, pain, brittleness, and deformity...

Avascular necrosis is a disease resulting from the temporary or permanent loss of the blood supply to the bones. Without blood, the bone tissue dies and causes the bone to collapse. If the process involves the bones near a joint, it often leads...

Spine fusion remains a common means of achieving stability in spinal surgery. Methods for obtaining fusion involve decortication of the host bed and introduction of a grafting material. Autologous bone has served as the standard material for these procedures in that its three cardinal properties encourage effective bone healing: osteogenic...

With an aging population the frequency of postmenopausal fractures is increasing. Methods to enhance the repair of osteoporotic bone repair therefore become more important to reduce the society burden of care. We asked if absorbable collagen sponges containing recombinant human bone morphogenetic protein-2 (rhBMP-2) have the potential to enhance bone...

Bone can be considered as a biphasic composite material, mineral as one phase, and collagen and ground substance as the other The combined substances are stronger for their weight than either substance alone Cortical bone is stiffer than cancellous bone and more brittle, withstanding less strain before failure than cancellous bone ...

Primary lymphoma of bone is an uncommon disease and must be separated from skeletal involvement in systemic lymphoma. The former is stage IE (extranodal, see Staging) disease and may present to the orthopedic surgeon prior to biopsy as a solitary bone lesion simulating a bone sarcoma. The latter, by definition,...

Even though prosthetic joints are a Good Thing, they are not a source of unalloyed joy to their recipients. Loosening and infection are two reasons why. There are other causes for a painful prosthetic joint, but these two items are always uppermost in the minds of orthopedists.
Why does a good...
