To permit a smooth entry into the water, platform divers assume a special position with their hands. An older method consists of hitting the water with both fists closed while holding one thumb in the palm of the other hand. In a newer technique fingers and wrists are hyperextended, the forearms pronated, and the hands overlapped. In this series of 21 divers, the injuries included 2 fractures and 5 sprains treated by conservative methods. Two divers required surgery: one with loose bodies in the radiocarpal articulation, the other with chronic rupture of the trapeziometacarpal ligament and synovitis of both extensor pollicis brevis and longus. Eighteen divers complained of pain caused by the impact of the hand with the water. A kinetic analysis with a video imaging system explains the mechanism and forces of water penetration.
为了能顺利入水,高台跳水运动员会用手摆出特殊姿势。一种较老的方法是双手握拳入水,同时将一只手的拇指握在另一只手的手掌中。一种较新的技巧是手指和手腕过度伸展,前臂旋前,双手交叠。在这21名跳水运动员中,损伤包括2处骨折和5处扭伤,采用保守方法治疗。两名跳水运动员需要手术:一名是桡腕关节有游离体,另一名是大多角骨掌骨韧带慢性断裂以及拇短伸肌和拇长伸肌滑膜炎。18名跳水运动员抱怨手部入水时的冲击导致疼痛。使用视频成像系统进行的动力学分析解释了水穿透的机制和力量。
