BONE by Robert C. Mellors, M.D., Ph.D. II. Congenital and Hereditary Bone Disorders 1. Achondroplasia General Considerations A chondroplasia is a congenital and often hereditary (autosomal dominant) skeletal disorder characterized by a unique form of dwarfism and bone deformity resulting in a disproportinate shortness of the extremities relative to the trunk. : Achondroplasia: note the disproportionate shortness of the extremities to the trunk in this form of dwarfism. Achondroplasia is caused by a failure of proliferation and column formation of epiphysial cartilage cells, that is, by a defect in endochondral bone formation which impairs the longitudinal growth of the tubular bones. Point mutations in the FGR3 gene (encoding fibroblast growth receptors) on human chromosome 4 p segregate with disease in achondroplasia families (Rousseau, F., et al. Nature 371:252-254, 1994). Pathology A chondroplasia shows various degrees of expression. The severest cases result in fetal or neonatal death, and milder cases survive and comprise the commonest type of adult dwarfism. The adult height in achondroplasia is usually less than four feet. The extremities (legs, arms, fingers, toes) are very short (micromelia) relative to the trunk which is only slightly shortened. Intramembraneous ossification is not affected. The head (cranial vault) is large. The root of the nose is depressed. The skeletal deformities just noted along with normal intelligence and sexual development distinguish achondroplasia from dwarfism resulting from endocrine and nutritional deficiencies and other causes.

Disorders of the Musculoskeletal System BONE DISORDERS Although we often take for granted the ability to walk, run, use our arms, or climb stairs, we should cherish the intricate workings of our musculoskeletal system that make free movement possible. When a bone problem, muscle disorder, or disease interferes with this delicate machinery, our movement may be painfully limited, our daily activity severely compromised. Musculoskeletal disorders—those affecting the skeleton and its system of joints—disrupt the normal quality of life more frequently than any other type of disease. More than 20 million Americans must cope with limited activity, significant disability, or restricted movement due to orthopedic problems. The human body contains 206 bones constituting about one-tenth of the total body weight (see figure 24.1 ). The bones' framework supports and protects many vital organs. For instance, the skull shields delicate brain tissue. The spinal column encases the spinal cord, the main pathway of nerves carrying messages between the body and the brain. The rib cage guards the heart, lungs, liver, and kidneys. Bones in the pelvic area anchor the spine, encircle the bladder and, in women, protect the reproductive organs and the developing fetus. Many people mistakenly view their skeleton as a static and unchanging entity. In fact, the skeleton continually resculpts itself. Every day of your life, bone tissue cells called osteoblasts and osteoclasts constantly create new bone and break down the old in a process called remodeling.

Hole's Human Anatomy and Physiology 8/e Shier/Butler/Lewis Student Online Learning Center Additional Readings Bone Disorders Skeletal Giantism is a condition of abnormally increased height that usually results from excessive cartilage and bone formation at the epiphyseal plates of long bones. The most common type of giantism, pituitary giantism, results from excess secretion of pituitary growth hormone. However, the large stature of some individuals can result from genetic factors rather than from abnormal levels of growth hormone. Acromegaly (ak'ro-meg'al-e) is also caused by excess pituitary growth hormone secretion. However, acromegaly involves growth of connective tissue, including bones, after the epiphyseal plates have ossified. The effect mainly involves increased diameter of all bones and is most strikingly apparent in the face and hands. Many pituitary giants also develop acromegaly later in life. Dwarfism, the condition in which a person is abnormally short, is the opposite of giantism. Pituitary dwarfism results when abnormally low levels of pituitary growth hormone affect the whole body, thus producing a small person who is normally proportioned. Achondroplastic (a-kon'dro-plas'tik) dwarfism, involving a disproportionate shortening of the long bones, is more common than proportionate dwarfing and produces a person with a nearly normal-sized trunk and head but shorter-than-normal limbs. Most cases of achondroplastic dwarfism are the result of genetic defects that cause deficient or improper growth of the cartilage model, especially the epiphyseal plate, and often involve deficient collagen synthesis. Often the cartilage matrix does not have its normal integrity, and the chondrocytes of the epiphysis cannot form their normal columns, even through rates of cell proliferation may be normal.

ViaHealth Disease and Wellness Information Bone Disorders ViaHealth's Bone Disorder Services Laboratories Cancer Care Orthopaedics Osteosarcoma What is osteosarcoma? Osteosarcoma is a type of bone cancer that develops in the osteoblast cells that form the outer covering of bone. It occurs most often in children, adolescents, and young adults. Approximately 900 new cases of osteosarcoma are reported each year in the US. It occurs nearly twice as often in males than in females, and represents 5 percent of all childhood cancers. Osteosarcoma most commonly occurs in the long bones around the knee. Other sites for osteosarcoma include the upper leg, or thighbone, the lower leg, upper arm bone, or any bone in the body, including those in the pelvis, shoulder, and skull. Osteosarcoma may metastasize, or spread, into nearby tissues of the foot, or into tendons or muscles. It may also metastasize through the bloodstream to other organs or bones in the body.

Davol, 76 Mildred Avenue, Swansea, MA 02777-1620 pdavol@labbies.com Growing Pains: Growth-Associated Bone Disorders in the Dog (revised and updated for 2000) What are "growing pains"? "Growing pains" are symptoms most often affecting medium, large, and giant breeds of dog: those breeds that are usually subjected to rapid growth periods within their first year of development. Symptoms of pain and lameness can be the result of any trauma to bones, joints, or the supporting soft tissues, but often they are caused by specific diseases of the bone. During normal growth and development, cartilage growth precedes bone formation. The cartilage grows and becomes calcified. Vessels from the bone marrow invade this calcified layer of cartilage. Some of the calcified cartilage is resorbed, but some remains and is used as a framework for the bone. In instances of bone disease, one or more of these steps is interrupted and the formation of bone ceases or causes a defect if bone formation continues. Exposure of incompletely formed or abnormally formed bone to pressure and tension resulting from movement causes symptoms of pain and lameness. It is important to understand that "growing pains" are a symptom and do not constitute a diagnosis. For proper treatment of bone disease and prevention of further bone damage leading to secondary complications of osteoarthritis, it is essential that the underlying cause of pain and lameness be identified.

Paget's disease of the bone is a chronic bone disorder in which bones become enlarged and deformed. Bone may become dense, but fragile, because of excessive breakdown and deformation of bone. The disease affects both genders, is rarely found in people under the age of 40, and occurs in up to 3 percent of the US population. What causes Paget's disease of the bone? The exact cause of Paget's disease of the bone is unknown, but it is suggested to be due to a slow viral infection of bone and may include a heredity factor. What are the symptoms of Paget's disease of the bone? The following are the most common symptoms of Paget's disease of the bone. However, each individual may experience symptoms differently. Symptoms may include: pain in the affected area bone deformity in the affected area susceptibility to fractures in the affected area headache (if the affected area is the skull) hearing loss (if the affected area is the skull) The symptoms of Paget's disease of the bone may resemble other bone disorders or medical problems. Always consult your physician for a diagnosis.
