Large ceramic THR heads

The prosthesis manufacturer Finsbury now supplies a series of THR prostheses with ceramic heads in the sizes 32 to 48mm (and the matching acetabular cups). For patients where hip resurfacing and BMHR no longer are regarded suitable the transfer to THR will be more attractive and known problems like luxation fewer due to the increasing size that begins to approach the joint size of our natural hips. Still, patients should not accept such a prosthesis if not at least several in hip resurfacing specialized surgeons (abroad) have determined that neither hip resurfacing or BMHR are possible, because each THR still means the amputation of the femoral neck and introduction of ”stress shielding”. Even the largest size 48mm is still too small for men and therefore more suitable for women who do have smaller sized hips than men.
