... % of the injuries. Wrist injuries were most common among injured snowboarders and knee injuries among injured alpine skiers. The percentage of knee injuries was almost twice as high for females compared to males throughout the period ( p <0.001). The prevalence of lower leg fracture for injured alpine skiers ⩽12...

... injured snowboarders suffered more fractures (34%) than alpine (20%) and telemark skiers (18%) (P < 0.001), but fractures of the lower leg were uncommon among snowboarders (1%) and telemarkers (2%) compared to alpine skiers (7%) (P < 0.001). Lower leg fractures accounted for 3.5% of the injured...

... containing fractures yielded much higher hydraulic conductivities, on the order of 10 −6 cm/s. This difference in hydraulic conductivities is attributed to fractures, which were evident in the block specimens. Testing of the block specimens at higher overburden stresses showed that the hydraulic...

... as many ankle injuries (13%) as alpine skiers (4%) and snowboarders (4%). Injured snowboarders suffered more fractures (33%) than alpine (22%) and telemark (20%) skiers. Lower leg fractures were recorded for only 3.6% of the injured alpine skiers 20 years and older, whereas this injury accounted for 20...

... group. Fracture of the lower leg was the most serious of the LEER injuries, and accounted for 21% of the injuries in the youngest children and 10 percent in the age group 10 to 14 years. In contrast 18% of the older children suffered head injuries compared to only 5% in the younger children. Beginners...

..., 19% of all injuries and 45% of all upper extremity injuries were distal radius fractures. With the exception of the medial collateral ligament (MCL), there were few significant knee ligament or thumb injuries, but a disturbing number of tibia fractures, ankle fractures and ankle sprains, reminiscent...

... about 9% suffered a lower leg fracture, but 40% of these skiers were children under 15 years of age. Every third injury was binding/boot related, and those skiers who had performed a self binding release test were less at risk than those who had not performed this test. The number of skiers who had...

Beginners had an injury risk four times the average, whereas skiers taking formal skiing instruction during the current season were underrepresented among the injured skiers...

... Two hundred and sixty-two fractures of the femoral shaft were treated with the Grosse-Kempf interlocking nail. Mechanical complications occurred in 26 cases (10%): There were five broken nails (2%), four bent nails (1.5%), four proximal screw failures (1.5%), and thirteen major torsional...

... is used as an example of instrumentation by geologic and hydrologic criteria. Geology is that of a weathered, fractured, sedimentary rock mantle overlying deeper, less fractured, sedimentary rock strata. The focus of this paper is on describing the domain of and controls on ground-water flow within...

... In a study of ski injuries in Sapporo during 1979 through 1984, information regarding 1276 ski injuries was obtained. Children ages 6 to 12 accounted for 40% of all injuries observed. The most common injuries were fractures and sprains in the case of children, sprains in adolescents, lacerations...

... fractures. The average injury rate was 1.4 injured skier per 1000 participating racers. About 75% of the racers were younger than 16 years old, and the injury rate among them (0.7 per 1000) was significantly below that of skiers between the ages of 16 and 29 (3.8). The injury rate was also related...
