  • Patent number: 7128723
    Abstract: An orthopedic brace having length adjustable supports is provided. The brace comprises upper and lower supports rotatably connected by a hinge. Each of the supports comprises an elongate portion having a channel along part of its length, and a sliding upright that nests within the channel. The upright is incrementally longitudinally translatable within the channel so that the length of the support is adjustable. Flanges are provided along the edges of the channel to prevent lateral separation of the upright from the stationary portion. A spring-biased button protrudes from an upper surface of the channel. The button cooperates with one of a plurality of holes in the upright, providing a positive lock to retain the upright in one of a number of predetermined positions within the channel. The upright is also completely removable from the channel. Removal of the upright from the channel shortens the brace. Straps cooperate with brackets on the supports and/or uprights to secure the brace to a patient's leg.
