: In skiing, a strong correlation has long existed between injuries and the development of ski equipment. For instance, just one change in the shape of skis leads to changes in skiing style, which can make the skier adopt knee positions likely to create injury. In this review, we discuss the morphology of ski-related injuries. In the 18 years since 1996, 10,561 patients with skiing and snowboardingrelated injuries visited the Ishiuchi Ski Clinic Niigata Prefecture, Japan . Of these, 3,703 patients had ski-related injuries. We reviewed patients medical records and questionnaires and observed their skiing using a video camera with 3-dimensional computer graphics software analysis. When knee sprains and fractures were considered together, the 18-year overall incidence was 30 , but in the 3-year period from 2009-2012, the incidence increased to 31 . Skiing style has changed from conventional alpine skiing to carving skiing, which has made the knee unstable, thereby increasing the risk of anterior cruciate ligament injury or tibial plateau fracture.
: Dynamic changes during walking were evaluated in kyphotic patients by measuring load pressure using an F-SCAN, a sensor that facilitates measurement of plantar pressure. The subjects consisted of kyphotic patients demonstrating severe thoracic kyphosis and more than 1 old compression fracture at the transitional zone between the thoracic and lumbar vertebrae. The results of analysis in these patients were compared with those in healthy subjects. As a structural evaluation, plumb-line shift from the central sacral line (P-CSL) in a standing profile was correlated with changes in load pressure. The types of central loci of the plantar pressure were analyzed in these two groups, the total load between heel contact and toe off was evaluated in the respective locus, and the integrates and load duration were also determined in the respective compartments after dividing the plantar region into the following 4 compartments : heel, plantar arch, anterior foot, and toe. kyphotic patients maintain their anteroposterior equilibrium during walking by shifting the centroid in the posterior direction, a P-CSL. Therefore, the F-SCAN demonstrated an increased proportion of weightbearing at the heel. Points of application of the centroid in the planta pedis were almost identical between kyphotic patients and healthy subjects during natural standing. Therefore, it was considered that kyphotic patients maintain their anteroposterior equilibrium by increased integrates at the heel (prolongation of load times at the heel). That is, the interval between heel contact and plantar contact tended to increase with the degree of anterior P-CSL.
Despite many reports describing the surgical procedure for knee ligament reconstruction, especially the anterior cruciate ligament, there have been few reports on infection prevention and none on sterilizing reconstruction materials using povidone-iodine during surgery. Here we report our surgical techniques for infection prevention. The participants included 522 patients who underwent arthroscopic knee ligament reconstruction at our hospital from April 2001 to October 2005. Despite taking various measures after cases of infection in 2001, such as the selection of sutures and arti cial ligaments, and the use of indwelling intra-articular drains, the infection rate was not reduced to zero. Recently, we felt that soaking reconstruction ligaments in povidone-iodine and then washing with saline povidone-iodine pickling immediately prior to burr-hole insertion may prevent bacterial infections caused by surgical instruments and the surgery. Therefore, in this study, we examined the effects of our techniques for intraoperative and postoperative infection prevention, including povidone-iodine pickling. Although there were 6 cases of
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
