Abstract
An orthopedic implant includes a main body, which has a downward tapered configuration formed of a plurality of steps of different diametrical sizes arranged along a drilling axis, each of the steps includes a cylindrical and a conical section, and the conical section of the lowest and diametrically smallest step is downward tapered into an apex; an external thread, which is externally formed on the main body to cover all the cylindrical sections but not the conical sections; a plurality of lateral cutting flutes, which are formed on the external thread into the main body and extended from the apex to the diametrically largest step with a spacing distance left between upper ends of the lateral cutting flutes and a top of the largest step. The orthopedic implant can be independently driven into a bone without the need of bone cutting using drill bits in advance and enables good osseointegration.
