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 skier days per season on average Services all the local medical needs for Mt Buller in winter About 2500 patients per season 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 skiers 1 Upper limb injuries account for 50% 2 56% of upper limb injuries are fractures 3 Wrist fractures alone account for nearly a fifth of all injuries in snowboarders Impact rather than torsional 4 Possibility of force transfer more proximate 5 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 = 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. Russell (2007)
