Method and screw for repair of olecranon fractures

A method for repairing olecranon fractures in the ulna comprising the steps of:

• creating a hole in the proximal end of the ulna, the hole extending from the proximal end of the ulna to the fracture to define a first region, and from the fracture to the proximal end of the medullary canal to define a second region;
• selecting a screw having a cancellous section end a medullary section extending from a leading end of the cancellous section to a leading end of the screw, where the cancellous section include a threaded region adjacent the medullary section and the medullary section is adapted to fit into the medullary canal of the ulna, the threaded region being provided with a larger outside diameter than the diameter of the hole in the second region;
• installing the medullary section into the hole up to the threaded region;
• and
• rotating the screw to drive the threaded region into the hole until the threaded region engages the cancellous bone surrounding the hole in the second region, end the medullary section extends from the second region substantially into the medullary canal, where the medullary section is chosen to have a diameter along its entire length that is less than the corresponding diameter of the medullary canal into which the medullary section is adapted to fit.
