  • This study was carried out to investigate the current trends in skiing-related research from existing literature in the field of kinematics, measurement sensor and computer simulation. In the field of kinematics, research is being conducted on the mechanism of ski turn, posture analysis according to the grade and skill level of skiers, friction force of ski and snow, and air resistance. In the field of measurement sensor and computer simulation, researches are being conducted for researching and developing equipment using IMU sensor and GPS. The results of this study are as follows. First, beyond the limits of the existing kinematic analysis, it is necessary to develop measurement equipment that can analyze the entire skiing area and can be deployed with ease at the sports scene. Second, research on the accuracy of information obtained using measurement sensors and various analysis techniques based on these measures should be carried out continuously to provide data that can help the sports scene. Third, it is necessary to use computer simulation methods to clarify the injury mechanism and discover ways to prevent injuries related to skiing. Fourth, it is necessary to provide optimized ski trajectory algorithm by developing 3D ski model using computer simulation and comparing with actual skiing data.

  • Snowboarding has become one of the premier alpine sports. The past decade has seen the popularity of snowboarding increase dramatically and the recent Winter Olympic Game showcased the strong visual appeal of the sport and the youth-oriented lifestyle and culture that accompanies it. The injury profile of the sport has also undergone change along with technological advances in boot and binding systems and the changing demographics of the sports participants. Central to the development of injury-prevention strategies is knowledge of the profile of injuries that occur, understanding those who are at particular risk and, if possible, the biomechanical factors involved in each injury type. Snowboarding was initially considered a dangerous, uncontrolled, alpine sport - an opinion based on little or no scientific evidence. That evidence has rapidly grown over the past decade and we now know that snowboard injury rates are no different to those in skiing; however, the injury profile is different. The purpose of this review is to give some perspective to the current snowboard injury literature. It discusses not only the demographic profile of those injured and the type of injuries that occur, but also gives some insight into the progress that has occurred in determining the impact of specific prevention strategies, such as splints to prevent injuries to the wrist/forearm. As the literature indicates, however, some things will not change, e.g. injuries are more likely to occur in beginners and lessons need to be reinforced as a fundamental aspect of any injury-prevention strategy.

  • Src family kinases (SFKs), an important group of non-receptor tyrosine kinases, are suggested to be excessively activated during various types of tissue fibrosis. The present study investigated the effect of KF-1607, an orally active and a newly synthesized Src kinase inhibitor (SKI) with proposed low toxicity, in preventing the progression of renal interstitial fibrosis. Unilateral ureteral obstruction (UUO) surgery was performed in 6-week-old male C57BL/6 mice to induce renal interstitial fibrosis. Either KF-1607 (30 mg/kg, oral gavage) or PP2 (2 mg/kg, intraperitoneal injection), a common experimental SKI, was administered to mice for seven days, started one day prior to surgery. UUO injury-induced SFK expression, including Src, Fyn, and Lyn kinase. SFK inhibition by KF-1607 prevented the progression of tubular injury in UUO mice, as indicated by decreases in albuminuria, urinary KIM-1 excretion, and kidney NGAL protein expression. Renal tubulointerstitial fibrosis was attenuated in response to KF-1607, as shown by decreases in α-SMA, collagen I and IV protein expression, along with reduced Masson's trichrome and collagen-I staining in kidneys. KF-1607 also inhibited inflammation in the UUO kidney, as exhibited by reductions in F4/80 positive-staining and protein expression of p-NFκB and ICAM. Importantly, the observed effects of KF-1607 were similar to those of PP2. A new pan Src kinase inhibitor, KF-1607, is a potential pharmaceutical agent to prevent the progression of renal interstitial fibrosis.

  • We report here on a case of Achilles tendon rupture associated with ipsilateral bimalleolar fracture that was caused by ski injury. The association of an ankle fracture with rupture of the Achilles tendon is even more infrequent, although both injuries alone are extremely common. We treated as a operation of Achilles tendon repair with Krackow method and open reduction with Tension-band wiring technique for bimalleolar fracture.

  • Purpose: We purposed to analyze the incidence and the patterns of the injuries associated with anterior cruciate ligament(ACL) tears. Materials and Methods: We retrospectively reviewed 547 knees that had undergone ACL reconstructions and compared the associated injuries according to the time of injury(acute vs. chronic), the cause of injury(sports vs. non-sports) and the type of sports. Results: Medial collateral ligament(MCL) injury and bone contusion were more in acute injury group less than 3 months after trauma(p=0.001, 0.019) and the injuries of medial or lateral meniscus were more in chronic injury group more than 3 months after trauma(p=0.014, 0.029). The trochlea in acute injury group(p=0.027) and the medial femoral condyle in chronic injury group(p=0.011) had higher incidence of chondral injury. Grade I, II chondral injury was frequent in acute injury group(p=0.016) and grade III, IV chondral injury was frequent in chronic injury group(p=0.017). Lateral meniscus injury was frequent in sports injury group(P=0.035). Medial collateral ligament injury was frequent in ski(P=0.005), and chondral injury was in gymnastics(P=0.017). Conclusions: The incidences of medial and lateral meniscus tears and grade III, IV chondral defects were high in chronic injury group. According to the causes of the tears and the types of sports, some differences in the incidence and pattern of associated injuries were found.

  • Tricuspid regurgitation after blunt chest trauma is rarely seen in the emergency department. A 19-year-old patient visited our emergency department with chest discomfort after collision with his brother while skiing. Recently, Skiing as a winter sports has become popular with the Korean people, so there is an increasing tendency for patients with diverse traumas associated with ski accidents to visit the emergency department. From simple abrasions or contusions to deadly injuries with unstable vital signs, we are seeing many kind of injuries in the emergency department. We present the case report of a patient with tricuspid regurgitation after a blunt chest trauma during the skiing.
