Elastofibroma arising in the foot.

Elastofibroma is a nonneoplastic proliferation of collagen and abnormal elastic fibers, with a marked predilection for the subscapular area. We have described an elastofibroma occurring in a previously unreported location, the plantar surface of the foot. Trauma has been implicated in the pathogenesis of these lesions, regardless of site, and our patient's history of intensive dance and aerobic exercise further supports this relationship.

Nonclostridial gas gangrene: late infection after hip pinning.

An 86-year-old diabetic man had a late, gas-forming infection about Knowles pins. Although blood cultures were negative, a urinary tract infection followed by infection with the same organism in bone, muscle, and lung strongly supports hematogenous spread of E coli from the genitourinary system in this patient. The genitourinary system is well recognized as a source of bacteremia, and the skeletal system is the most often affected distant tissue when this occurs.

Intercollegiate Lacrosse Injuries.

In brief:Injury data for an intercollegiate lacrosse team were collected after one season of practices and games and compared with injury data from a summer league team. Only five players (15%) completed the season without injury, and there were 78 total injuries to the 34 players. The most frequent injury was ankle sprain.

Bone mass in lifetime tennis athletes.

The effects of physical exercise on the status of bone mineralization for a population of lifetime athletes were investigated. The bone mineral content of the radii of experienced male tennis players was measured. The bone mass of the radius of the playing arm (mean, 1.

The "blind side" of the medial meniscus.

The major posterior insertion of the medial meniscus is not into the tibial plateau proper but into a rather deep recess behind the intercondylar eminence. The shape of the meniscus in relation to the curve of the meniscotome and its angle of approach, and also the surgeon's inability to see posteriorly from an anterior incision make posterior capsular incision desirable in many cases. A posteromedial incision, added to the normal anteromedial one in 40 of 215 medial meniscectomies, did not increase perioperative morbidity.

Hand and wrist injuries in the athlete.

Injuries to the hand and wrist are probably among the most common injuries incurred by the athlete. Neglect of such injuries may result in irreparable damage to the hand or wrist. This summary of the more common injuries to these areas seen in the athlete, with a description of the recognition and treatment, gives the reader insight into the multiple considerations the athlete and coach must have.

Tennis injuries: prevention and treatment. A review.

When players are engaged in the sport of tennis, injuries may occur to the eyes, in the neck, to the shoulder and back, arm and elbow, wrist and hand, and feet. The key to prevention and treatment of these injuries is good coaching and a formal stretching and strengthening program. The drooped "tennis shoulder" of professionals and senior tennis players is a natural response to heavy use.

Lacrosse Injuries.

Lacrosse injuries are fewer and less severe than expected considering that sticks are used, checking is permitted, and protective gear is sparse.

The Long-Term Effects of Playing Tennis.

In 50 years of competitive tennis these super seniors have stayed in good condition and overcome problems ranging from tennis shoulder to heart disease.

Olympic Weight-Lifting Injuries.

Because most Olympic weightlifting injuries are caused by inflexibility and improper technique, the well-trained lifter concentrates on improving these abilities.

Equestrian injuries. Results of a prospective study.

In a prospective study involving 110 injured equestrians, there were no noteworthy correlations between age, sex, or experience of the amateur riders and injury occurrence. Tack failure caused several injuries. Among fox hunters the incidence was related only to frequency of hunts.

Cross-Country Bicycling: Physiological Effects.

Although percentages of body fat didn't change significantly, this study shows that transcontinental bicycling promotes higher levels of fitness, indicated by lower body mass, lower heart rates, and higher maximum breathing capacities.
