Proximal humeral stabilization system

Abstract

Devices, systems, and methods for bone stabilization, especially proximal humeral stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion. The stabilization system may include an intramedullary nail having an upper portion and a lower portion extending from the upper portion, the upper portion and the lower portion including a plurality of holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and/or one or more of the plurality of holes in the intramedullary nail and into the bone. The plate and nail may each be used alone or in combination together to stabilize a fracture in a long bone, such as a humerus.

What is claimed is: 
     
         1 . A stabilization system configured to stabilize a humerus, the system comprising:
 a bone plate, the bone plate comprising an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion, the bone plate comprising first and second polyaxial openings, a plurality of fixed angle openings positioned on the enlarged head portion of the plate, and a plurality of elongated slots positioned on the elongated portion of the plate;   a plurality of polyaxial calcar fasteners configured to be received in the first and second polyaxial openings and configured to be aimed at a calcar region of the humerus;   a plurality of fixed angle, locking fasteners configured to be received in the plurality of fixed angle openings, respectively, and configured to be aimed at a humeral head of the humerus; and   at least one polyaxial, non-locking fastener configured to be received in one of the plurality of elongated slots to permit dynamic compression of the bone and configured to be aimed at a shaft of the humerus.   
     
     
         2 . The stabilization system of  claim 1 , wherein the plurality of polyaxial calcar fasteners have self-forming threads on a head portion of the fasteners, and the polyaxial calcar fasteners are configured to lock to the first and second polyaxial openings of the plate. 
     
     
         3 . The stabilization system of  claim 1 , wherein the enlarged head portion extends at an angle relative to the longitudinal axis. 
     
     
         4 . The stabilization system of  claim 1 , wherein the plate further comprises a second plurality of openings configured as suture holes to receive sutures configured to secure the plate to surrounding tissue. 
     
     
         5 . The stabilization system of  claim 1 , wherein the system further includes an intramedullary nail configured to be positioned at least partially in the intramedullary canal of the humerus. 
     
     
         6 . A stabilization system for stabilizing a bone, the system comprising:
 an implant having an upper portion and a lower portion, the upper portion configured and dimensioned to be cylindrical and having a width or diameter greater than the lower portion, and the lower portion extending from the upper portion and having a length greater than a length of the upper portion, the upper portion and the lower portion including a plurality of holes; and   a plurality of fasteners configured to be received by the plurality of holes of the upper and lower portions of the implant,   wherein the lower portion is being capable of being positioned in an intramedullary canal and the upper portion is capable of being positioned in a humeral head.   
     
     
         7 . The stabilization system of  claim 6 , wherein the system further includes a plate having a plurality of holes, the plate configured to be positioned on a lateral surface of the bone. 
     
     
         8 . The stabilization system of  claim 7 , wherein the plurality of holes of the plate are aligned with the plurality of holes of the upper and lower portion of the implant. 
     
     
         9 . The stabilization system of  claim 6 , wherein the length of the lower portion is greater than a width or diameter of the lower portion. 
     
     
         10 . The stabilization system of  claim 6 , wherein the upper portion includes an opening to receive a portion of the lower portion. 
     
     
         11 . The stabilization system of  claim 10 , wherein the lower portion is received in the opening in the upper portion and is threaded into the upper portion to secure the upper and lower portions together. 
     
     
         12 . The stabilization system of  claim 6 , wherein the upper portion is configured to be rotated within the humoral head to align the humoral head with the intramedullary canal.
