    • A fracture brace for a leg has an interior jacket for placement over the front of a leg, and for wrapping around the medial and lateral sides of a leg outside of a posterior shell. The posterior shell fits over the calf and the lateral and medial sides of the leg. Straps anchored on the shell unite the jacket and the shell to form an enveloping case for the leg that permits transmission of bearing pressures through the fleshy part of the leg, the tibia, and the brace. An interior pad integral with the jacket extends along the anterior of a leg from the proximal tibia to the distal tibia. There the pad wraps to the sides to provide padding for the bony prominences of the medial and lateral malleolus. A footplate connects to the jacket through a pair of uprights, each of which attaches to the footplate through a pivot and to the jacket by hook and pile fasteners. The attachment to the jacket permits adjustment of the footplate with respect to the jacket and therefore the foot with respect to the tibia: (1) in translation generally along the axis of the tibia, (2) in translation generally along an axis through the length of the foot, (3) in rotation generally around the axis of the tibia, and (4) in rotation generally about the axis through the length of the foot. The footplate can rotate about axes generally medial-to-lateral and through pivots connecting the footplate and the uprights.
    • 用于腿部的骨折支架具有用于放置在腿的前部上的内部护套,并且用于围绕后壳外侧的腿的内侧和外侧缠绕。 后壳适合小腿和腿的外侧和内侧。 锚固在壳上的皮带将护套和外壳结合在一起,以形成用于腿部的包封壳,其允许轴承压力通过腿,胫骨和支架的肉质部分传递。 与护套一体的内部衬垫沿着腿部的前部从胫骨近端延伸到远端胫骨。 那里的垫子包裹在侧面,为内侧和外侧的踝骨的骨骼突起提供衬垫。 一个脚板通过一对立柱连接到护套,每个立柱通过枢轴连接到脚踏板,并通过钩和紧固件连接到护套。 与护套的连接允许相对于护套调节脚板,因此相对于胫骨调节脚部:(1)大致沿着胫骨的轴线平移,(2)通常沿着穿过长度的轴线平移 (3)通常围绕胫骨的轴线旋转,以及(4)通常围绕通过脚的长度的轴线旋转。 脚踏板可以围绕轴线大致内侧和外侧旋转,并通过连接底板和立柱的枢轴旋转。
