to "push" the slope away, as landing a wrist which is bent at a 90 degree angle increase the chance of it breaking. Rather, landing with the arms stretched out (like a wing) and slapping the slope with the entire arm is an effective way to break a fall. This is the method used by practitioners of judo and other martial arts to break a fall when they are thrown against the floor by a training partner. The risk of head injury is two to six times greater for snowboarders than for skiers and injuries follow the pattern of being rarer, but more severe, with experienced riders. Head injuries can occur both as a consequence of a collision and when failing to carry out a heel-side turn. The latter can result in the rider landing on his or her back and slamming the back of his or her head onto the ground, resulting in an occipital head injury.[54] For this reason, helmets are widely recommended. Protective eyewear is also recommended as eye injury can be caused by impact and snow blindness can be a result of exposure to strong ultra-violet light in snow-covered areas. The wearing of ultra-violet-absorbing goggles is recommended even on hazy or cloudy days as ultra-violet light can penetrate clouds.[55] Unlike ski bindings, snowboard bindings are not designed to release automatically in a fall. The mechanical support provided by the feet being locked to the board has the effect of reducing the likelihood of knee injury – 15% of snowboard injuries are to the knee, compared with 45% of all skiing injuries. Such injuries are typically to the knee ligaments, bone fractures are rare.[50] Fractures to the lower leg are also rare but 20% of injuries are to the foot and ankle. Fractures of the talus bone are rare in other sports but account for 2% of snowboard injuries – a lateral process talus fracture is sometimes called "snowboarder's ankle" by medical staff. This particular injury results in persistent lateral pain in the affected ankle yet is difficult to spot in a plain X-ray image. It may be misdiagnosed as just a sprain, with possibly serious consequences as not treating the fracture can result in serious long-term damage to the ankle.[50] The use of portable ultrasound for mountainside diagnostics has been reviewed and appears to be a plausible tool for diagnosing some of the common injuries associated with the sport.[56]
