Abstract
Various embodiments disclosed herein relate to a humeral resection guide. The humeral resection guide can include a cutting block having a side surface and a cutting surface. The cutting surface can be configured to constrain at least one degree of freedom of movement of a cutting instrument during surgical alteration of the humerus. The humeral resection guide can include a boom extending away from the cutting surface of the cutting block, the boom comprising a cut depth adjustment feature disposed along at least a portion of a length of the boom. A method of using the humeral resection guide is disclosed. A method of manufacturing the humeral resection guide is also disclosed.
Claims9
A method of manufacturing a humeral resection guide comprising a cutting block and a boom extending away from the cutting surface of the cutting block at an obtuse angle, the method comprising:
- for each humerus of a plurality of humeruses, adjusting the boom relative to a handle assembly such that the cutting block is disposed at a target cut depth for that humerus;
- for each humerus of the plurality of humeruses, determining a target location along a length of the boom to which the handle assembly is connected when the cutting block is disposed at the target cut depth by measuring a distance from an end of the boom to a cross arm of the handle assembly;
- determining a range of target locations along the length of the boom based at least in part on the determined target locations for the plurality of humeruses;
- and
- providing a cut depth indicator on the boom at a target region of the boom based at least in part on the determined range of target locations, the cut depth indicator comprising a plurality of parallel lines extending in a direction perpendicular to the length of the boom and spaced apart along the length of the boom.
A method of surgically altering a humerus using a humeral resection guide comprising a cutting block and a boom extending away from the cutting block, the method comprising:
- orienting a side surface of the cutting block to face an exterior surface of the humerus;
- and
- adjusting the boom relative to a handle using a cut depth indicator on the boom to position the cutting block at a target cut depth by measuring a distance from an end of the boom to a cross arm of the handle, the cut depth indicator comprising a plurality of parallel lines extending in a direction perpendicular to the length of the boom and spaced apart along the length of the boom.
