Forty million individuals participate in organized softball leagues each year in the United States. Eighteen million additional student athletes and young adults also participate in organized baseball league play. ⋯ Fortunately, numerous interventions independently have been shown to be effective at reducing the injury scenario, which has grown to be of epidemic proportion. Interventions such as break-away bases, batting helmets, face shields on helmets, lighter mass baseballs, and teaching and reiteration of the fundamentals of softball and baseball all have been effective in preventing millions of injuries and billions of dollars in healthcare costs each year in the United States.

The snowmobile was developed to move people and supplies, and for emergencies in regions where heavy snow prohibited the use of conventional vehicles. Today, snowmobiling has become a popular winter sport enjoyed by more than 2 million people of all ages in North America. However, the modern snowmobile can weigh in excess of 600 pounds and travel at speeds exceeding 90 miles per hour. ⋯ Injuries incurred in children and adults often are extremity fractures, but can involve any organ system. Similar to motor vehicle accidents, multisystem trauma occurs frequently with head injury the leading cause of death. Reduction in injury and death rates is urgently needed and can be accomplished through education and legislation.

Case ReportsExcision of a bony spike without fixation of the fractured clavicle in a jockey.
Various modalities are available for treatment of a clavicle fracture. Conservative treatment is successful in most cases. Open reduction, when indicated, usually is accompanied by fixation of the fracture. ⋯ The fracture was opened and a bony spike was excised extraperiosteally without doing internal fixation of the fracture to avoid skin necrosis and allow early return to work. The patient returned to his profession 2 weeks after surgery. Radiologic and clinical examinations revealed a satisfactory outcome at the 6-month followup.

Comparative StudyCircumferential and posterolateral fusion for lumbar disc disease.
Clinical outcome of low back fusion is unpredictable. There are various reports discussing the merits and clinical outcome of these two procedures. The patients were selected from a population of patients who had chronic low back pain unresponsive to conservative treatment. ⋯ The posterolateral fusion group had a 63.9% satisfactory outcome and the posterior lumbar interbody fusion group had an 80% satisfactory outcome using the Oswestry disability index for postoperative assessment. There was 61.1% improvement in working ability in the posterolateral fusion group and 77.1% improvement in the posterior lumbar interbody fusion group which was not statistically significant. The authors consider instrumented circumferential fusion with posterior lumbar interbody fusion better than instrumented posterolateral fusion for managing chronic disabling low back pain.

Comparative StudyWrist injuries in guarded versus unguarded first time snowboarders.
In 1999, a study was done examining the injury risk and pattern in first time snowboarders versus first time skiers. Although these rates were similar, snowboarders sustained a higher percentage of injuries to the upper extremity, particularly wrist sprains and fractures. As an extension of this previous study, the protective value during snowboarding of an off-the-shelf wrist guard originally designed for inline skating was tested. ⋯ Five hundred fifty-one snowboarders wore wrist guards and a control group of more than 1800 snowboarders did not wear wrist guards. Forty wrist injuries were sustained in the control group (2.2%), compared with no injuries (0%) in the snowboarders who wore wrist guards. Importantly, there was no increase in more proximal or distal upper extremity injuries in the group of snowboarders who wore wrist guards.
