An orthotic leg elevator for elevating the leg of a subject during a post-operative period or in other situations in which it is necessary to avoid direct contact between the leg and a bed or other surface, or to raise the leg with respect to a surface. The leg elevator includes a rectangular block whose top side has formed therein a concave trough extending the length of the block to cradle the leg of the subject so that his foot is then adjacent the front end of the trough. Nested in the trough at its rear end is a knee-supporting piece which underlies and conforms to the knee joint. Secured to the block are three detachable straps adapted to engage the cradled leg at spaced positions. The first strap engages the leg above the ankle; the second at an intermediate position between the ankle and the knee, and the third just above the knee, thereby immobilizing the leg. To accommodate the leg elevator to different situations, attachable to the underside of the block are slabs or wedges which serve to adjust the height of the elevator, or the relative heights of the knee and foot of the cradled leg, or the inclination of the block relative to the horizontal plane.

[ I claim:] [1.] An orthotic leg elevator for keeping a leg of a human subject out of contact with a bed or other surface, said elevator comprising:A. a rectangular block of predetermined length having a top side and a bottom side, said top side having a concave trough that extends the length of the block in parallel to the bottom side to cradle the leg of the subject received therein so that the foot is then adjacent a front end of the block and projects thereabove, and his knee is then adjacent a rear end of the block;B. a removable Achilles tendon supporting arched piece nested adjacent the front end of the trough and underlying the Achilles tendon of the leg cradled in the trough whereby a front portion of the leg extends above the top side of the block;C. a removable knee-supporting arched piece nested adjacent the rear end of the trough and underlying the joint of the knee whereby a rear portion of the leg extends above the top side of the block and the knee cap projects above the block; andD. detachable straps to secure the leg to the block at spaced apart positions; one of said straps being adapted to engage the leg just above the ankle, a second of said straps being adapted to engage the leg at a position intermediate the ankle and the knee and a third of said straps being adapted to engage the leg above the knee to firmly secure the leg to the leg elevator regardless of the activity of the subject.
