[The roller discotheque--a quickstep to the hospital? An analysis of 196 accidents].

A retrospective study comprising a period of 16 months was made in order to analyse the injuries of 196 patients occurred when visiting a roller discothèque. Injuries of the upper extremities had the highest incidence (56.6%); the most frequent of these lesions was the distal fracture of the radius (23.4%, n = 46). Rather slight injuries are predominant indeed, however, even severe injuries are observed, e.g. supracondylar fractures of the humerus, fractures of the ankle joint, or vertebral fractures. The probability of an accident occurring during the visit of a roller discothèque could be estimated for the first time due to the particularities of the first-aid system of Hamburg. Taking into consideration the number of 364 000 admission-tickets sold during the above mentioned period, the probability of being injured is 0.54%.
