Shin Splints What do a runner, dancer, and military recruit have in common? The possibility of a painful stress injury of the tibia called shin splints. Muscles and tendons of the lower leg pull on bone when workout intensity increases, and inflammation is often the result. The tender, mildly swollen shin responds well to rest, ice, and over-the-counter pain relievers. Proper stretching and new shoes also help, as does cross training to vary the impact on the leg. Too much too soon is too hard on the tibia! Shin splints occur as a result of pulled tendons and muscles of the lower leg. What is the best way to avoid shin splints? Ice the lower leg prior to training. Apply heat after exercise. No pain no gain: Increase the intensity of the workout. Gradually build up the workout schedule and do more cross training in order to avoid doing too much too fast.

Hip Fracture A hip fracture, or a "broken hip," actually involves the femur, not a hip bone. The two types of hip fractures are femoral neck fractures and intertrochanteric fractures. In a femoral neck fracture, the femoral head is separated from the femur (and its blood supply). There is no disconnection to the blood supply in an intertrochanteric fracture. As a result, such fractures may be repaired with a metal plate and screws. Which of the following is a NOT a likely explanation for the increased occurrence of hip fractures in the elderly? The proximal epiphysis of the femur has a preponderance of spongy bone, which is weaker than compact bone. Osteoporosis reduces the ability of bone to be effectively remodeled. Bone density decreases with age. There is a reduced ability to balance that often accompanies old age.

Club Foot The arches of the foot are usually present at birth. Sometimes, however, they fail to develop properly. In club foot (congenital talipes equinovarus), abnormal muscle development distorts growing bones and joints. One or both feet may be involved. The condition can be mild, moderate, or severe. In most cases, the tibia, ankle, and foot are affected. The longitudinal arch is exaggerated, and the feet are turned medially and inverted. If both feet are involved, the soles face one another. This condition affects 1 in 1000 births and is twice as common in boys as girls. Prompt treatment with casts or other supports in infancy helps alleviate the problem. Fewer than half the cases require surgery. A more convex longitudinal arch partly characterizes a foot deformity called congenital talipes equinovarus.

Carpal Tunnel Syndrome The carpal bones articulate with one another at joints that permit limited sliding and twisting. Ligaments interconnect the carpal bones and help stabilize the wrist joint. The tendons of muscles that flex the fingers pass across the anterior surface of the wrist. These tendons are sandwiched between the intercarpal ligaments and a broad, superficial transverse ligament called the flexor retinaculum. Inflammation of the connective tissues between the flexor retinaculum and the carpal bones can compress the tendons and the adjacent median nerve. The result is pain, weakness, and reduced wrist mobility. This condition, called carpal tunnel syndrome, is common in occupations that require repetitive wrist motion. Many students complain about severe wrist pain after typing yet another multiple-page report. This pain is the hallmark of carpal tunnel syndrome, which is an inflammation of connective tissue due to repeated movement. Which of the following structures is NOT involved in this disorder? extensor retinaculum intercarpal ligaments flexor retinaculum median nerve

Stress Fractures Running is beneficial to overall health but places the foot bones under more stress than does walking. Stress fractures are hairline fractures that develop in bones subjected to repeated shocks or impacts. Stress fractures of the foot usually involve one of the metatarsals. These fractures are caused either by improper placement of the foot while running or by poor arch support. In a fitness regime that includes street running, proper support for the bones of the foot is essential. An entire running-shoe market has arisen around the amateur and professional runner's need for good arch support. Stress fractures due to running primarily affect the metatarsals.

It is Caitlyn's first day of "big kids" school. She cries a little when she kisses her Mom good-bye and gets on the bus. She feels lost when she gets to school, but a kind kindergarten teacher meets her and leads her to her new classroom. The best part of her day is getting to go out to the playground. Caitlyn has seen the climbing structure from outside the playground fence many times, but this is the first time she has the chance to climb all the way to the top. She feels very grown up, perched up so high. Suddenly her foot slips, and she feels herself falling to the ground. She stretches out her right hand to break her fall just before she hits the ground. As she lands, she feels and hears a crack in her elbow. "Help!" Caitlyn cries. The school nurse examines the child's deformed elbow, notices there is no pulse in her wrist, and springs into action. She splints Caitlyn's arm and calls the orthopedic surgeon. "Doc, we have a five-year-old who has an elbow injury following a fall on her outstretched hand, with no distal pulses." "Oh no," groans the surgeon. Of all the playground fractures, this is likely to be the most difficult to treat. Caitlyn has a supracondylar distal humerus fracture, a true surgical emergency.
