  1. Wrist guards should be compulsory for school-aged snowboarders. Research presentation ACRRM 5th Scientific Forum Dr Graham Slaney

  2. Outline • Background • Study objective • Study design • Results • Conclusion

  3. Mt Buller Medical Centre • Mt Buller - one of Australia’s busiest ski resorts • 300 000 skier days per season on average • Services all the local medical needs for Mt Buller in winter • About 2500 patients per season • 100-120 wrist fractures per season • 2 doctors, 3 nurses, 1 radiographer • Ski patrol services ski slopes

  4. Background - Wrist injuries • Snowboarders have 2.4 times as many fractures as skiers1 • Upper limb injuries account for 50%2 • 56% of upper limb injuries are fractures3 • Wrist fractures alone account for nearly a fifth of all injuries in snowboarders • Impact rather than torsional4 • Possibility of force transfer more proximate5 1. Bladdin (1993) 2. Young (1999) 3. Idzikowski (2000) 4. Pino (1989) 5. Hagel (2005)

  5. Study Objective To ascertain the association: • between wrist guard use and wrist fracture in snowboarders in Australia • between wearing wrist guards and the severity of wrist and elbow injury

  6. Study design • Case control study 2004 and 2005 ski seasons • Cases - snowboarder seen at clinic with fractured wrist (n = 119) • Controls - snowboarder seen at clinic for any reason other than fractured wrist (n = 375) • Questionnaire about wrist guard use and snow sport behaviour • Clinic staff recorded details of injury • Logistic regression used to determine adjusted odds ratios

  7. Characteristics associated with Wrist Fracture

  8. Study Results - Wrist Fracture • Adjusting for significant variables • Odds of having worn wrist guards lower in snowboarders with wrist fracture (cases) • Adjusted OR = 0.58; 95% CI, 0.32–1.04;P = 0.07 • Wearing wrist guards in Australia reduces wrist fracture injury by about 42%

  9. Study Results - Elbow Injury 15 elbow injuries amongst the 494 snowboarders • 5 soft tissue • 4/86 wearing wrist guards • 1/391 not wearing wrist guards • adjusted OR, 17.6; P = 0.01 • 10 elbow fracture or dislocation • 3/86 wearing wrist guards • 7/391 not wearing wrist guards • adjusted OR, 1.84; P = 0.39 Wrist guards protective of overall injury severity

  10. Conclusions Snowboarders wearing wrist guards: • Elbows protected – important new finding • Reduce wrist fracture injury in Australia by about 42% • Data consistent with international literature (52% to 87%)6 • Novices strongly recommended • Mandatory for School-aged children 6.
