Update to L THR Revision on 7/10/19. X-rays showed that my femur is a "champagne flute" type. It is very narrow at the bottom and very wide at the top. The first THR femoral stem planted into the bottom, but was moving side to side up top and causing incredible pain.
In case anyone else has this issue ... they reamed the entire femur to create an oblong shape, as wide and uniform as safely possible. The new femoral stem looks like a long, thin rectangle rather than the usual triangle. A "collar" was placed the top of the femur to add additional stability. 20" posterior scar, 50 staples and 2 days in the hospital. Recovery has been longer and slower than the first L THR July 2018, but showing progress daily.
My revision surgeon was amazing - patient, methodical, attention to detail, consulting with colleagues - other surgeons through wound-care experts. He even called me at home the night before the surgery to allay fears and ask if I had questions and changed the bandaging himself post-operative. He and his staff made sure to treat my husband (primary caregiver) in the same respectful, caring, personalized manner. Dr. Demetri Economedes at Cary Ortho in Cary, NC.
