Age groups in Canadian amateur ice hockey with associated hip injury data.

Notes: Until the age of 15 years, players sequentially move to the next age group. Players aged 15–20 years play either Midget, Junior, or Juvenile level hockey depending on their skill level. The highest skill level is the Junior level. Once over the age of 20 players transition to the Senior level. The number of injuries reported to Hockey Canada in each age group from 2005 until 2010 is shown. The proportion of total reported hip injuries occurring in each age group and associated 95% confidence intervals are also depicted.
