The role of biomechanics in the epidemiology of injuries.

In this paper a review of the epidemiology of both traumatic and overuse injuries is presented with special emphasis on the role of biomechanics. Biomechanical analysis of injuries and the specific sports has increased in sophistication to such a degree we have a much better understanding of both aetiology and management. Particularly in the area of overuse injuries this biomechanical data can also be utilised in prevention. This paper discusses acute traumatic injuries with emphasis on knee injuries. A detailed examination of knee injuries during skiing is explored. In addition, cervical injuries in gridiron football and rugby are outlined. Overuse injuries occurring during running are next discussed. Aetiological factors including training errors, muscular dysfunction and inflexibility, footwear, running gait and lower extremity malalignment are considered. Overuse injuries in swimming, dance, gymnastics and throwing sports are briefly discussed. Biochemical analysis is felt to be important in developing strategies that lead to rule changes, alteration of training techniques and improvement in equipment and footwear.
