Humeral osteotomy guide
First Claim
1. A device for guiding an osteotomy to be performed on the proximal end of a human humerus comprising:
- a proximal end sawguide for defining an osteotomy saw lineproximal end of the humerus;
a distal end means for stably aligning the sawguide on the proximal end of the humerus;
a radial arm connecting the sawguide and the means for aligning;
the radial arm being rotatably connected to the sawguide at a proximal end thereof for rotatable movement of the sawguide for use in connection with a left or right humerus;
the radial arm being slidably mounted at a distal end in the means for aligning for slidable movement of the radial arm in the distal to proximal direction;
the sawguide engaging a selected surface on the proximal end of the humerus and supporting the proximal end of the radial arm above the humerus;
the means for aligning engaging the distal end of the humerus and supporting the distal end of the radial arm above the humerus.

Abstract
A device for guiding an osteotomy to be performed on the proximal end of a humerus that has a proximal sawguide alignable on a selected surface of the proximal end of the humerus for defining a saw line thereon; a radial arm connecting the sawguide to a distal mechanism for stably aligning the sawguide, the distal alignment mechanism has a pair of opposing lateral and medial epicondyle arms pivotally engageable with the lateral and medial sides of the distal end of the humerus, the epicondyle arms being pivotally mounted in a distal cross arm, the distal end of the radial arm being slidably mounted in the cross arm for distal to proximal slidable movement therein; the proximal end of the radial arm being rotatably connected to the sawguide through a proximal guide bar; the radial arm being supported above the humerus by the proximal guide bar and the epicondyle arms.

19. A device for guiding an osteotomy to be performed on the proximal end of a humerus comprising:
-
a proximal sawguide alignable on a selected surface of the proximal end of the humerus for defining a saw line theron; a radial arm connecting the sawguide to a distal means for stably aligning the sawguide, the distal alignment means comprising a pair of opposing lateral and medial epicondyle arms pivotably engageable with the lateral and medial sides of the distal end of the humerus, the epicondyle arms being pivotably mounted in a distal cross arm, the distal end of the radial arm being slidably mounted in the cross arm for distal to proximal slidable movement therein; the proximal end of the radial arm being rotatably connected to the sawguide through a proximal guide bar; the radial arm being supported above the humerus by the proximal guide bar and the epicondyle arms. - View Dependent Claims (20, 21)
