Two U-20 World Cup rugby studies were undertaken during 2008 under the control of Dr Molloy (IRB – Medical Officer):
The studies were carried out in accordance with the IRB approved consensus statement on definitions and procedures for injury surveillance studies in rugby union.
The injury data are being collated and analysed centrally by Colin Fuller at the Centre for Sports Medicine (CSM, Nottingham, England).
JWT (Chile):
data available from 6 of 8 teams. 24 time loss injuries sustained during the competition corresponding to
50.0 injuries/1000 player hours.
Mean severity of injuries – 15.2 days; Median severity of injuries – 6 days.
JWC (Wales):
data available from 15 of 16 teams. 87 time loss injuries sustained during the competition corresponding to
58.0 injuries/1000 player hours.
Mean severity of injuries – 23.3 days; Median severity of injuries – 7 days.
Overall:
data available from 21 of 24 teams. 111 time loss injuries sustained during the competition corresponding to
56.1 (CI: 46.6 to 67.6) injuries/1000 player hours.
Mean severity of injuries – 21.5 days; Median severity of injuries – 7 days.
The incidence of injury was significantly lower than that observed during the 2007 RWC
(83.9; CI: 71.9 to 97.9),
the English (2002-2004) Premiership
(91; CI: 87 to 96),
and 2008 results from Super 14
(96.3; CI: 69.0 to 111.7).
The incidence was lower but not significantly different (p=0.065) from results obtained during the 2008 Vodacom Cup
(71.2; CI: 60.0 to 84.5).
The severity of injury was within the range reported previously for the RWC (mean: 14.7; median: 7 days), English Premiership (mean: 18 days), Super 14 (mean: 13.4; median: 5 days), and Vodacom Cup (mean: 21.2; median: 12 days).
Based on the data available, the incidence of injury at the international U-20 level of play is significantly lower than that observed at the senior level but the severity of injury is similar.
