A bio-compatible femoral stem is made from a bio-compatible titanium alloy or cobalt-chromium alloy, each of which have an elastic modulus far greater than that of natural bone. When the implant heals within a bone cavity, the implant essentially carries substantially the entire load. Transfer of load to the surrounding bone tissue is lost or resorbed due to lack of use after implant healing. Flexing a stiff implant applies a very large load at the implant distal end. The bone cortex is thereby allowed to thicken due to excessive load, causing thigh pain long after implant healing. The femoral implant has a bone ingrowth coating on the proximal end, allowing firm attachment of the implant in the bone cavity. The distal end has a central aperture and a helical machined groove that permits flexing of the distal portion of the femoral implant stem. This flexing is occurs in a manner similar to surrounding bone tissue, preventing thigh pain.
