To evaluate the frequency of concussion in Swedish ice hockey and to establish a uniform grading and treatment model for concussions of different severity. ⋯ As this injury is potentially dangerous it must be treated seriously according to a simple treatment model presented. In cases of repeated concussions during the same season, a longer period of time away from play is suggested. In players who have sustained several concussions over the years a thorough medical examination including EEG, CT/MRI, and neuropsychological tests should be performed. If any of these is pathological the player should be advised to give up ice hockey.

Posterior dislocation of the sternoclavicular joint is uncommon, accounting for less than 0.1% of all dislocations. Since 1824 a little more than 100 cases have been reported, and the majority in the past 20 years. ⋯ A typical case is described. The importance of this injury is that there is often a delay in diagnosis with potentially serious complications.

Ankle inversion injuries are the most common injury in sport and yet treatment is controversial. One result is chronic ankle instability, an injury for which criteria for surgical intervention are unclear. ⋯ This suggests that a good history of chronic instability is more sensitive an indicator than conventional investigations. Stress views under anaesthesia may confirm the problem.

Despite international concern about the safety of trampolines, they have become increasingly popular in New Zealand. While internationally attention has centred on a relatively few cases of catastrophic cervical spine injury, little research effort has been directed at placing these incidents in a wider context. To redress this, a descriptive epidemiological study of trampoline-related injury in New Zealand was undertaken. ⋯ Fractures were the commonest type of injury (68%), and the body site most frequently involved was the upper limb (53%). There was no evidence of a high incidence of severe head and neck injuries. It was concluded that, although existing trampoline standards addressed many of the issues raised by this research, measures to reduce the impact of falls from trampolines to the ground and to prohibit the provision of trampolines as 'play equipment' are required.

A group of 129 subjects (67 men and 62 women) experiencing sports headache was established using a questionnaire. A wide range of information was gathered, focusing on the mode of onset, time course, characteristic features and associated symptoms of sports-related headache. Criteria for the varieties of sports headaches were established using head trauma and then migraine to divide subgroups of sports headaches. ⋯ Effort-exertion headache was the most common type of sports headache. Although effort-exertion headache could be separated into subjects who had an acute severe headache induced by anaerobic exercise (exertion headache) from those having a substantial headache lasting hours initiated by aerobic exercise (effort headache), most subjects with effort-exertion headache in this study appeared not to fall into any discrete subgroups. Trauma-related headaches were experienced mainly by men in contact sports, while women more commonly had non-trauma-related headache in running and jogging.
