Hip Resurfacing Implants: A Literature Review and Our Experience

Cadossi M, Tedesco G, Sambri A, Mazzotti A and Giannini S

Hip resurfacing offers a suitable solution for young patients with high function demands and good bone quality affected by hip diseases.

The bone stock preservation along with the restoration of the normal proximal femur anatomy, the lack of stressshielding and the resumption of 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 bearing: pseudotumors, peri-implant osteolysis and chronic elevation of metal ions serum levels.

Recent data suggest that the ideal candidate for hip resurfacing is an active male, younger than 65 years old, suffering from primary or post-traumatic osteoarthritis with a femoral head diameter larger than 50/54 mm.

Based on these selection criteria literature reports an implant survival similar to total hip replacement. Our experience confirms the low failure rate and the excellent functional outcomes, with stable metal ions serum levels over time in well-functioning implants. Proper surgical technique, correct patient selection together with the right choice of a well established prosthetic model are essential elements for the long-term success of these implants.
