Abstract
Abstract Apparatus that permits a hip surgery patient to be rotated to lie on his side while maintaining the affected leg in a desired degree of abduction and external rotation includes a splint portion that grasps the affected leg and that is secured to an elevating portion. The elevating portion includes a splint-mounting bar that is hinged to a stationary base that lies on the bed. The axis of the hinge is approximately colinear with the spine of the patient. The apparatus constrains the affected leg to move on an arcuate path as the patient is rolled onto his side whereby the affected leg swings to the elevated position. The elevating portion includes locking devices for maintaining the affected leg in the elevated position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
Apparatus to facilitate turning a patient lying on his back in a bed onto one side while maintaining the opposite leg in a desired orientation with respect to the patient's body, the desired orientation including a chosen degree of abduction, a chosen degree of rotation, and a minimal degree of flexion, said apparatus comprising in combination: a splint for supporting the opposite leg of the patient in the desired orientation with respect to the patient's body; and, elevating means attached to said splint for elevating the opposite leg of the patient by constraining said splint to move along an arcuate path from an initial position on the bed to an elevated position as the patient is being turned onto his side.
Claim 2
Dependent Claim
