[Associated factors to severe sport injuries].
OBJECTIVE
To identify the risk factors associated to severe sport injuries.


METHODS
Case-control study, with non probabilistic of consecutive sample cases. The risk factors criteria for severe injuries were established by experts' consensus in patients diagnosed with injury caused during sports practice between July 2004 and March 2005. These patients were attended in the emergency room at the Magdalena de las Salinas High Medical Specialty Unit in Mexico City.


RESULTS
There were included 131 patients with sport injuries; there were 76.3% men and 23.7% women. The mean age was 21.6+/-8.6. There were non severe injuries, (concussions, muscle strains, sprained) in 55% of patients and 45% of patients had severe injuries (fractures, dislocation, fracture-dislocation, physeal injury). In the case of severe injuries, it was associated with working out in a non reglamentary area [odd ratio (OR) of 2.5, p=0.01, CI (1.2-5.1)], soccer practice [OR of 2.4, p=0.01, CI (1.2-4.8)], body axis injury [OR of 5.9, p=0.004, CI (1.6-21.9)], indirect injury mechanism [OR of 2.2, p=0.04, CI (0.9-5.2)], sport practice<or=4 hours/week [OR of 2.9, p=0.004, CI (1.4-6.2)], no warm up [OR of 2.2, p=0.02, CI (1.04-4.6)].


CONCLUSIONS
With the identified factors we can explain 37.6% of the severe injuries with statistical significance, the other factors here studied did not show statistical significance, but had clinical significance. In following studies we recommended to use a bigger sample than we used in this study.
