摘要:

In brief: Myositis ossificans—a benign process—is characterized by calcification of a hematoma that resulted from a severe contusion or strain or repeated trauma. Diagnosis is based on radiographic evidence of a calcified mass along with a history of recent trauma to the affected area. Management should be directed at minimizing or preventing extension of the original injury. Rest, ice, compression, and elevation (the classic treatment for any soft-tissue injury) is recommended as initial therapy. Gentle, painless range-of-motion exercises may be prescribed to help restore mobility. Padding can be used to protect the affected area from additional trauma.

摘要:

In brief: Occasionally the team physician may be called on to examine someone, a spectator for example, who has chest pain. After ensuring that the person's vital signs are stable, the physician must determine whether the cause is potentially catastrophic or relatively minor. The author describes the distinguishing factors.

摘要:

In briefTo assess the decline in maximal aerobic power (V O2max) with age, two groups of men were studied: Fifteen exercisers were followed from age 45 to 68, and 15 controls were measured while training at age 52 and again at age 70 after being detrained for 18 years. Resting blood pressure of 120/78 was unchanged in the exercisers but rose from 135/85 to 150/90 in the nonexercisers. V O2max measured by open circuitry declined 13% in the exercisers from 44.4 to 38.6 ml-min−1-kg−1; in the nonexercisers it declined 41% from 34.2 to 20.3 ml-min−1·kg−1. The VOmax loss was primarily due to a combined loss of maximal heart rate and stroke volume. The data suggest that regular aerobic exercise retards the usual loss in aerobic power with age and present important implications for the aging population in relation to social, economic, and health benefits.

摘要:

An overt trauma is not always the source of subsequent swelling and pain. This case conference is a lesson in looking for obscure causes.

摘要:

In brief: Previous reports of arm wrestling fractures have involved the distal third of the humerus. What makes this case unique is that the fracture occurred at the radial neck. The mechanism of injury probably involved extreme pronation where the radial head is locked into the capitellum—an area of potential weakness. Treatment was conservative, consisting of keeping the elbow flexed, 90°in a sling.

摘要:

In brief: Magnetic resonance imaging (MRI) is useful for assessment of capsuloliga-mentous and other periarticular soft-tissue structures of the knee. It is especially valuable for its ability to accurately diagnose tears of the anterior cruciate ligament (ACL). MRI findings that indicate an ACL tear include frank disruption of the ligament, waviness to the anterior margin of the ligament, and areas of heterogeneous increased signal within the ligament on sagittal T2-weighted images.

摘要:

In brief:The number of children diagnosed as hyperactive continues to grow each year. And a question often arises about whether athletic activity is appropriate for these children. Evidence strongly suggests that not only is it appropriate, but that certain sports can improve self-esteem and can make them feel less like oddities among their peers.

East Germany has a long-established reputation for producing some of the world's finest athletes. But now that the reunification of Germany is becoming more likely, many people wonder whether the winning tradition will be lost

摘要:

Losing weight to improve performance is common—even accepted—among sports competitors. When weight loss gets out of hand, though, coaches and others close to the athlete may have to intervene to help stave off a serious eating disorder.
