Bone Fractures Copyright 2003 Pearson Education, Inc. publishing as Benjamin Cummings A break in a bone Types of bone fractures Closed (simple) fracture break that does not penetrate the skin Open (compound) fracture broken bone penetrates through the skin Bone fractures are treated by reduction and immobilization Realignment of the bone

BONE REPAIR Callus zone of tissue repair Several Steps1. blood clot forms 2. 2-3 days later, cells enter and produce fibers which hold bones together cartilage is then produced 3. osteoblasts enter the callus and form spongy bone takes 4-6 weeks 4. spongy bone is remodeled into compact bone this healing can take up to a year
Slide 13
Bone Fractures and Repair Fracture break resulting from trauma to the bone Types of Fractures Simple Fracture clean break, does not break the skin (closed fracture)
Slide 14
Compound Fracture bone breaks or tears through skin very serious, infection can occur
Slide 15
Slide 16
Comminuted Fracture bone breaks into pieces common in elderly, bones are more brittle
Slide 17
Compression Fracture bone is compressed or crushed common in vertebra common in older people due to osteoporosis
Slide 18
Depressed Fracture bone is pressed inward common in skull fracture
Slide 19
Impacted Fracture bone ends are forced into each other common when attempting break your fall with outstretched arms
Slide 20
Spiral Fracture results from excessive twisting force
Slide 21
Greenstick Fracture incomplete break (like a green twig) common in children due to more flexibility in bones than adults

Bursitis Inflammation of the Bursa (fluid filled sac surrounding the joint). A bursa can become inflamed from injury, infection (rare in the shoulder), or due to an underlying rheumatic condition. Bursitis is typically identified by localized pain or swelling, tenderness, and pain with motion of the tissues in the affected area.

Slide 31
Tendonitis Sometimes the tendons become inflamed for a variety of reasons, and the action of pulling the muscle becomes irritating. If the normal smooth gliding motion of your tendon is impaired, the tendon will become inflamed and movement will become painful. This is called tendonitis, and literally means inflammation of the tendon. The most common cause of tendonitis is overuse.
Slide 32
Slide 33
Carpal Tunnel Syndrome Any condition that causes swelling or a change in position of the tissue within the carpal tunnel can squeeze and irritate the median nerve. Irritation of the median nerve in this manner causes tingling and numbness of the thumb, index, and the middle fingers, a condition known as "carpal tunnel syndrome."

Osteoporosis Osteoporosis is a term that means "porous bones." It is a skeletal disease affecting women and men. Osteoporosis is a condition in which bones have lost minerals especially calcium making them weaker, more brittle, and susceptible to fractures (broken bones). Any bone in the body can be affected by osteoporosis, but the most common places where fractures occur are the back (spine), hips, and wrists.

Scoliosis Scoliosis is an abnormal curvature of the spine. If your child has scoliosis, the view from behind may reveal one or more abnormal curves. Scoliosis runs in families, but doctors often don't know the cause. More girls than boys have severe scoliosis. Adult scoliosis may be a worsening of a condition that began in childhood, but wasn't diagnosed or treated. In other cases, scoliosis may result from a degenerative joint condition in the spine.

Kyphosis With kyphosis, your spine may look normal or you may develop a hump. Kyphosis can occur as a result of developmental problems; degenerative diseases, such as arthritis of the spine; osteoporosis with compression fractures of the vertebrae; or trauma to the spine. It can affect children, adolescents and adults.

Slide 48
Lordosis A normal spine, when viewed from behind appears straight. However, a spine affected by lordosis shows evidence of a curvature of the back bones (vertebrae) in the lower back area, giving the child a "swayback" appearance.

Tuberculosis of the Spine- Potts Disease As a form of extrapulmonary tuberculosis that impacts the spine, Potts disease has an effect that is sometimes described as being a sort of arthritis for the vertebrae that make up the spinal column.tuberculosisarthritis Early signs of the presence of Potts disease generally begin with back pain that may seem to be due to simple muscle strain. However, in short order, the symptoms will begin to multiply.

Rickets Rickets is the softening and weakening of bones in children, usually because of an extreme and prolonged vitamin D deficiency. Some skeletal deformities caused by rickets may need corrective surgery.

Scurvy The human body lacks the ability to synthesize and make vitamin C and therefore depends on exogenous dietary sources to meet vitamin C needs. Consumption of fruits and vegetables or diets fortified with vitamin C are essential to avoid ascorbic acid deficiency. Even though scurvy is uncommon, it still occurs and can affect adults and children who have chronic dietary vitamin C deficiency.

Gout Gout is a disease that results from an overload of uric acid in the body. This overload of uric acid leads to the formation of tiny crystals of urate that deposit in tissues of the body, especially the joints. When crystals form in the joints it causes recurring attacks of joint inflammation (arthritis). Chronic gout can also lead to deposits of hard lumps of uric acid in and around the joints and may cause joint destruction, decreased kidney function, and kidney stones.arthritiskidney stones

Acromegaly Acromegaly is a serious condition that occurs when the body produces too much of the hormones that control growth. The hormone most often affected is called growth hormone, or GH. It is produced by the pituitary gland, a tiny organ at the base of the brain.hormonegrowth hormonepituitary glandorganbrain Growth hormone promotes growth of bone, cartilage, muscle, organs, and other tissues.cartilage muscle When there is too much growth hormone in the body, these tissues grow larger than normal. This excessive growth can cause serious disease and even premature death.

Poliomyelitis Poliomyelitis (polio) is a highly infectious disease caused by a virus. It invades the nervous system, and can cause total paralysis in a matter of hours. It can strike at any age, but affects mainly children under three (over 50% of all cases). The virus enters the body through the mouth and multiplies in the intestine. Initial symptoms are fever, fatigue, headache, vomiting, stiffness in the neck and pain in the limbs. One in 200 infections leads to irreversible paralysis (usually in the legs). Amongst those paralysed, 5%-10% die when their breathing muscles become immobilized. Although polio paralysis is the most visible sign of polio infection, fewer than 1% of polio infections ever result in paralysi
