Abstract: A head cradle for supporting a head of a patient during surgery when the patient is in a prone position. The head cradle includes a structural member with a body having a concave profile, a first end and a second end. The body has a forehead portion positioned at the first end for supporting a forehead of a patient and at least one cheek portion for supporting a cheek of the patient. The body includes an aperture defined through the structural member adjacent to the forehead portion between the first end and the second end. The structural member is sized to terminate at a position at or superior to a chin of the patient. A support member is provided to be received by the structural member and to interface with at least a portion of a face of the patient.

Abstract: An elbow joint boost device has first and second frames to be attached to the forearm and lower arm of a patient. A guide mounted on the first frame extends generally along the respective one of the forearm and upper arm. A link is mounted on the guide for sliding movement along the guide, and a spring acts in tension between the sliding link and a point on the second frame remote from the patient's elbow. As the patient straightens and bends the elbow, the link can slide along the guide, varying the leverage of the tension spring.
