Abstract
An angle measurement device is provided for determining the version angle for the prosthetic humeral head during shoulder replacement surgery. The device has a first collar for contacting the forearm and has a first coupling element in the form of a rod aligned with the ulna. The device has a second collar for contacting the upper arm when the elbow is flexed to 90°. The second collar has a second coupling element coupled thereto extending in a direction generally perpendicular to the humerus. The second coupling element is pivotally coupled to the first coupling element for rotation about a pivot point axis. An angle indicator having angle indicia is located at said pivot point and fixed to one of said first or second arm contacting collars for indicating the angle between the ulna and the humerus during external rotation of the forearm.
