While hip replacement surgery is generally performed in adulthood, there are many clinical conditions in which it is indicated to intervene even at a young age, with skeletal development not yet completed. Cases of severe subluxation of the hips, called luxoid, with severe synovitis and pain, require surgery in a short time, before the dislocation of the hips can become irreversible over time, with also deformation of the trochanter and the proximal part of the femur for traction of the gluteal muscles. As well as disorders of the growth plate of the femoral head or aseptic necrosis of the same, particularly painful, require early intervention of arthroplasty. In these skeletally immature animals, hip arthroplasty requires special measures to avoid complications and to ensure the maximum duration of the implants.
