…Hip resurfacing offers a suitable solution for young patients affected by
hip disease who have high function demands and good bone quality. Bone stock
preservation, restoration of the normal proximal femur anatomy, the lack of
stress shielding, and the possibility of resuming sporting activity are proven
advantages of hip resurfacing. However, there are some disadvantages, such as
fracture of the femoral neck, onset of neck narrowing, and possible
complications due to the metal-on-metal bearings, including pseudotumors, peri-implant
osteolysis, and chronic elevation of metal ions in serum levels. Recent data
suggest that the ideal candidate for hip resurfacing is an active male, younger
than 65 years, with primary or posttraumatic osteoarthritis, and with a femoral
head diameter larger than 50 to 54 mm. Based on these selection criteria, the
literature reports implant survival to be similar to that of total hip
arthroplasty. The current authors’ experience confirms a low failure rate and
excellent functional outcomes, with metal ion serum levels becoming stable over
time in well-functioning implants. Proper surgical technique, correct patient
selection, and the right choice of a well-established prosthetic model are
essential elements for the long-term success of these implants…
