Snowboarding injuries: an analysis and comparison with a pine skiing injuries Riyad B. Abu-Laban, MD Objective: To analyse the types and causes of injuries associated with recreational snowboarding and to compare these with the injuries seen in alpine skiing. Design: Prospective case series. Setting: Rural hospital near three large ski resorts. Patients: All people presenting to the Emergency Department with an injury caused by snowboarding during two ski seasons (1988-90). Of the 115 injured snowboarders identified, 73 (63%) completed the questionnaire. Information on the other patients was obtained from the hospital emergency records. Information was also obtained on seven alpine skiers who collided with snowboarders. Results: Of the snowboarders 87 (76%) were male, and the mean age was 20.3 years. A total of 132 injuries were documented. Of the respondents to the questionnaire 83% reported that their fitness level was excellent or above average, 36% had never been on a snowboard previously, 25% were in their first year of snowboarding, 39% reported excellent snow conditions, 59% reported light traffic on the hill, and 7% had consumed alcohol before their accident. Injuries were equally divided between the upper body and the legs, 75% of the lower-limb injuries involving the left (lead) leg. Significant differences were noted between the pattern of injuries in snowboarding and alpine skiing: snowboarders were less likely to have lacerations (0% v. 8% respectively), boot-top contusions (0% v. 4%), thumb injuries (1% v. 10%) and knee sprains (14% v. 27%) and more likely to have spinal injuries (12% v. 4%), foot or ankle injuries (28% v. 5%) and distal radius fractures (10% v. 1%). Conclusions: Snowboarding is associated with a unique pattern of injuries, the knowledge of which could influence snowboarder education, accident prevention and equipment design. Additional research is needed to understand better the types, causes and rates of injury associated with snowboarding.

S nowboarding, with its youthful participants, flashy padded clothing and specialized vocabulary, stands in sharp contrast to the more established sport of alpine skiing. Snowboards resemble small surfboards with fixed straps to hold the feet in position. They are used with the arms held outward, and shifts in weight cause the board to turn, slow down or stop. The majority of snowboards do not have a releasable binding system, and snowboarders do not use ski poles. In Canada most snowboarders wear soft boots that are often reinforced with hpavy tape or inserts. There has recently been an increased use of hard-shell special-

alpine skiing. It was thought that the knowledge gained from such an analysis could influence not only snowboarder education and accident prevention but also equipment design and perhaps the evolution of the sport.

Methods

The Mineral Springs Hospital is a 20-bed facility in Banff (population 5084 [in 1988]). It treats some 13 000 patients in the Emergency Department annually; about 10% of them have ski-related injuries. Banff National Park, Canada's oldest and most heavily visited national park, is an ideal location for ized footwear. There have been reports of crude "ski boards" studying snowboarding injuries, since there are three and "snurfers" from as early as 1963,12 but it has major ski resorts (representing some 800 000 skierbeen only in the last 5 years that the sport of days per year) within a short distance from the town snowboarding has grown and become popular at a of Banff. In addition, Banff hosted the 1984, 1988 phenomenal rate. Although viewed by many as a and 1991 North American snowboarding championpassing craze snowboards are now accepted at over ships. From November to May of 1988-89 and 198990% of North America's ski resorts.3 In 1989 there were some 1.5 million snowboarders worldwide, 40% 90 all people who presented to the Emergency of whom were in North America.3 This number was Department with an injury caused by snowboarding double that of the previous ski season, and thus were included in the study.

Whenever possible, a 23-item questionnaire was ries.4 The study was retrospective and surveyed by the injured snowboarder at either the completed and were who experienced mostly snowboarders hospital or the ski resort.

A binomial probability distribution was used to determine the significance of variation in the side of injury among the snowboarders. A two-dimensional table and a test based on the z statistic5 were used to compare the snowboarders and the alpine skiers, with assumed equal variances. The minimum accepted level of statistical significance was 0.01.

Results In all, 115 injured snowboarders (87 males) presented to the Emergency Department during the study period; 73 (63%) completed the questionnaire, and information was gathered from the emergency records for the remaining 42 (37%). The predominant reasons for not completing the questionnaire were other responsibilities or forgetfulness on the part of the emergency staff. None of the snowboarders refused to complete it when asked. The age of the 1 1 5 snowboarders varied from 12 to 35 (mean 20.3) years. Table 1 summarizes the responses of those who completed the questionnaire. There were seven documented cases in which alpine skiers had collided with snowboarders. Most of the skiers' injuries were mild sprains or contusions, although one 18-year-old had a fractured tibia and fibula after reportedly being "cut off" by a snowboarder. Table 2 shows the injuries of the snowboarders. In some cases patients had more than one injury (132 injuries in the 115 snowboarders); thus, the incidence rate of a particular injury was calculated on the basis of all injuries rather than the total number of patients seen. In Table 3 the results of this study are compared with the data from the final 2 years (1986 and 1987) of a large study of alpine ski injuries that was performed over a 15-year period.6 The raw data from the final 2 years, generously provided by the authors, were used to avoid any skewing caused by the changing injury pattern in skiing over the 15-year study period.

Discussion The findings suggest that snowboarding injuries usually involve young, well-conditioned males. This is consistent with other sources, which indicate that snowboarders are predominantly young males.3 Not surprisingly, most of the snowboarders reported that they were also skiers. As with alpine skiing7 most of the injuries occurred in the afternoon, when fatigue was likely. The proportion of snowboarders reporting a history of snowboarding injuries, 26%, is consistent with the proportion of alpine skiers reporting previous skiing injuries.7 NOVEMBER 1, 1991

Interestingly, 39% of the snowboarders reported "excellent" snow conditions, 59% reported "light" traffic on the ski hill, and only 7% reported alcohol consumption before their injury. These figures suggest that many of the injuries were caused by the individual snowboarder rather than by those factors; Table 1: Characteristics of snowboarders who responded to a questionnaire on the circumstances surrounding their injury

ries with those seen in alpine skiing, a sport that uses the same facilities and that has a well-documented pattern of injuries.6'9-" It is clear from Table 3 that the patterns of injury caused by snowboarding and skiing are distinctly different. Snowboarding accidents are characterized by wrist, -spinal and ankle injuries, a significant propensity toward injuries to the left rather than the right leg and a low incidence rate of lacerations and thumb injuries. Many of the differences between the injury patterns have likely explanations. It has been well established in alpine skiing that the ski's edge, once the binding has released, is responsible for most lacerations.'2 The fact that no lacerations were noted in the snowboarders is presumably due to the nonreleasable nature of most snowboard binding systems. The ski pole is integral in causing the typical "skier's thumb" injury to the ulnar collateral ligament of the first metacarpophalangeal joint.'3"'4 Since there is usually no pole used in snowboarding it is not surprising that such injuries were absent. Another distinction is the incidence rate of spinal trauma. The manner of riding probably puts snowboarders at greater risk for falling backward and thus for axial-loading injuries, a conclusion also reached by Pino and Colville.4 Such injuries are comparatively less common in alpine skiing, likely because most accidents involve a forward fall.'5 For example, the incidence rate of coccyx injuries is between 0.15% and 0.30% in alpine skiing,'6 as compared with the 4.6% in snowboarding found in this study. Arm injuries are another area that may be

related to the manner of falling, since snowboarders had a high incidence rate of distal forearm fractures. Although there were fewer shoulder dislocations in snowboarding this difference was not significant. However, the sport may prove to have a lower incidence rate of shoulder dislocations than alpine skiing because of the absence of ski poles, which are thought to contribute to some 24% of such injuries in skiers.'7 There is a dramatic difference in the distribution of lower-leg injuries, ankle and foot injuries predominating in the snowboarders and knee and boot-top injuries in the skiers. This difference is best explained by the comparatively reduced protection of the soft boots commonly used by snowboarders. The benefit of such boots is that they likely prevent the significant stress on the leg that causes contusions or fractures. In addition, the fixed binding of both feet to a snowboard likely decreases the possibility of valgus stress on the knee, a frequent cause of medial ligamentous injury in alpine skiing. Many studies have shown a change in the types of lower-leg injuries seen in alpine skiing during the last 50 years.6"'0"'8 '9 This change is related to a move from soft boots and fixed bindings to stiff boots and releasable bindings. In 1942, 46% of alpine skiing injuries involved the foot and ankle; by 1976 the rate had dropped to 7%.10 However, the incidence rate of tibial fractures increased, from 3% in 1942 to 16% in 1964, and then decreased to 6% in 1976, presumably because of refinements in binding systems. The incidence rate of knee injuries from alpine skiing has remained relatively stable through the years,'0 although the pattern has changed dramatically: the

incidence rate of anterior cruciate injuries has increased, and there has been a propensity toward complete ligamentous tears.20 One could speculate that the changing pattern of leg injuries in alpine skiing may occur in snowboarding. Although ankle injuries were predominant in snowboarding, this pattern could change if the more rigid boots popular in other countries are substituted for the soft boots currently used in Canada. In addition, snowboard technology is changing rapidly. Should a reliable releasable binding system appear on the market the nature of leg injuries could completely change. Of the 37 ankle injuries caused by snowboarding 28 (76%) occurred on the left side, as did 15 (7 1%) of the 21 knee injuries. This is presumably because most snowboarders use a left-foot lead on the board, and the lead foot is more prone to injury, a conclusion also reached by Pino and Colville.4 (A right lead is known as a "goofy foot" in the vernacular of snowboarding.) Unfortunately, the snowboarders were not questioned regarding their stance, since this factor was not anticipated when the questionnaire was designed. A final area in which the pattern of injuries may differ between snowboarding and alpine skiing is femoral fractures. Such fractures are known to account for 0.6% of alpine ski injuries;2' thus, given the number of injuries seen, one might have expected to see at least one such injury in this study (although its absence is not statistically significant). Interestingly, Pino and Colville4 found no femoral fractures in 1 10

snowboarding injuries. It has been established that the speed of travel directly influences the incidence of femoral fractures in alpine skiing.22 Such injuries may prove to be less common in snowboarding simply because snowboarders often travel at significantly slower speeds than alpine skiers. This could change as more snowboarders become experienced and increase their speed on steeper hills.

Risk of snowboarding-related injury

accidents resulting in more than very minor injuries, the rate of injury per 1000 snowboarder-days was 8.0 to 16.0. Although this rate is higher than the corresponding rate of 2 to 7 injuries per 1000 alpine skier-days'0 it was calculated on the basis of limited data. This study suffered from several design limitations. More specific questions regarding speed, boot type, foot position and injury mechanisms would have strengthened the findings. The absence of this information results in some of the above conclusions being speculative. In addition, a method of determining the total number of snowboarders at a resort over a specific period, correlated with the number of injuries, would provide a more accurate estimate of the injury rate.

Conclusions This study represents the first known analysis of the types, patterns and causes of injuries in recreational snowboarders. Snowboarding is clearly associated with a different pattern of injuries than alpine skiing, and this pattern may change with the evolution of the sport. The boots, boards and binding systems used in snowboarding have changed a great deal during the last 5 years and will probably continue to do so. In addition, many ski areas are constructing "half pipes" (specialized runs for aerial manoeuvres) for use by experienced snowboarders. These changes, along with an expected decrease in the proportion of novice snowboarders, may well influence the types, patterns and incidence of injuries. The evidence suggests that snowboarding is associated with a higher risk of injury than alpine skiing; however, this could be attributed to the proportionally greater number of novice snowboarders. The need remains for a large study to assess accurately the risk of injury in snowboarding, though it is certainly clear that there is a high risk of injury during one's first day on a snowboard. Lessons before one attempts snowboarding could reduce this risk and should be encouraged. As with any new sport further research will help to provide a better understanding of snowboarding injuries. Research could be directed toward determining the exact mechanism of accidents and the variation in injury types and patterns with changes in equipment, rider ability and technique. Further knowledge could influence equipment design, snowboarder training and ski resort regulations in order to ensure that snowboarding is both safe and enjoyable.

It seems commonly assumed that the manner of riding a snowboard, without ski poles or a releasable binding system, leads to an increased risk of injury. The true risk is difficult to assess, since for various reasons most ski resorts do not record the daily number of snowboarders. On the basis of information from the ski industry and snowboard merchants estimates of the average number of snowboarders at the three ski resorts in the Banff area during the study period varied from 20 to 40 per day (7200 to 14 400 snowboarderdays). Given the number of accidents this study I thank the medical, nursing, administrative and health identified, which probably represents most of the records staff of the Mineral Springs Hospital for making 1102
