1) The objectives of author's present study were 42, 245 patients with ratio of males to females of 7 to 3 in 44, 327 affected locations, covering the period of 23 years from the December of 1956 to the end of March of 1979.
2) All the injuries thus treated can be classified into 18, 815 (42.5%) of sprains, 11, 838 (26.7 %) of fractures, 9, 650 (21.8%) of lacerations, 2, 812 (6.4%) of contusions, 752 (1.7%) of dislocations and 460 (1.0%) of others.
3) Looking from auther's statistical study of the ski injuries in the past 23 years, the development of the ski equipments have largely effected on the ski injuries.
4) The lacerations on the head, face and arm are increased when the safety bindings have come into wide use. So, we expect the effect of the ski-stopper replacing the strap, in order to decrease the lacerations.
5) Injuries of the ankle have been decreased because of the plastic ski boots. Especially, “the ski fractures”, or, the abducted and external rotated fractures of the lateral malleolus are decreased remarkably.
6) The knee sprains, or, the ligamentous strains of medial colateral ligament of knee joint have been increased, because the stiff and high backed plastic ski boots have come into wide use.
7) Fractures of the lower legs and boot top fractures have been increased, according the development of the ski boots, such as from the leather boots to buckled boots to plastic boots.

Intra-arterial chemoradiotherapy for advanced oral cancer has recently been reported and can preserve the form and function of the tongue by avoiding surgery at the primary site. We report here a case of advanced tongue cancer treated with intra-arterial chemoradiotherapy that preserved phonation and swallowing function. A 71-year-old man presented with an ulcerative mass, 43×28 mm in size, extending from the left lingual margin to the base of the tongue. The pathological diagnosis was squamous cell carcinoma based on biopsy results, and the clinical diagnosis was left lingual carcinoma (cT3N0M0, stage III) based on imaging findings. A polyurethane catheter was inserted into the left lingual artery, and intra-arterial chemotherapy was administered using docetaxel (15 mg/m2/week, total dose 60 mg/m2) and cisplatin (5 mg/m2/ day, total dose 125 mg/m2) with concurrent radiotherapy (2 Gy/day, total dose 50 Gy). Posttreatment biopsy results showed no tumor cells, and complete response was achieved, thus avoiding surgical resection of the primary site. Six years after completing treatment, the patient remains in good health with no recurrence, metastasis, phonation problems, or dysphagia.
