[Swimming pool accidents in Denmark].
INTRODUCTION: The purpose of this article was to estimate injuries in connection with swimming pool activities. MATERIAL AND METHODS: Through The Register of Accidents of The State Institute of Public Health, data of injuries in swimming pools were collected for the period 1998-1999. In that period of time the NOMESKO-classification was used for registration of injuries, a specific classification based on registration of injuries at five different Danish hospitals corresponding to 14% of the Danish population. RESULTS: During the period of investigation the average number of injuries was 349 per year, corresponding to a rate of incidence of 49.9 per 100,000. There was a considerable dominance of the youngest age groups among the injured. The age group 0-14 years accounted for 60% of the injured. The dominant type of injury was simple fall. The type of lesions varied according to the age of the injured. DISCUSSION: There was an insignificant increase from 1998 to 1999. Due to a presumed difference in iatrotropic threshold there was probably a bias of selection. The number of injuries corresponded to a total of 2500 injuries in Danish swimming pools per year, corresponding to 1 injury per 10,000 persons using Danish swimming pools. There were no comparable studies, neither Danish nor foreign. In Danish swimming pools no recommendations were available, only what we call advice on how to conduct oneself in the pool area. It would probably be possible to reduce the number of injuries in Danish swimming pools by using preventive steps, for instance non-skid mats, ban on running and elimination of sharp and hard objects in swimming pools.

Poor results with the Shuttle Stop: resorbable versus nonresorbable intramedullar cement restrictor in a prospective and randomized study with a 2-year follow-up.
In a randomized prospective study we compared 2 femoral plugs as regards probable migration of the restrictor, cement leakage and possible early aseptic loosening. In group I, the femoral canal was plugged with a resorbable Shuttle Stop (HC Implants, BV. Leiden, The Netherlands). In group II, a nonresorbable restrictor of polyethylene was used (De Puy, UK). Both groups were identical as regards age, gender and primary disease. All patients were followed for at least 2 years after surgery. Postoperatively, we found more failures with displacement of the femoral plug and cement leakage in group I than in group II. At the 2-year follow-up, we found no differences in stem loosening or grade of radiolucent lines in the cement-bone interface. We can not recommend the Shuttle Stop for femoral canal sealing in total hip replacememt.
