In the first stages:
There are non-aggressive operations, such as forage or decompression of the area lack of blood supply. These operations are performed by minimally invasive or even percutaneous techniques. It can be applied bioengineered substances such as tricalcium phosphate derivatives that provide good resistance to compression and act as scaffolding through which penetrate cells of the body with capacity for bone neoformation and stem cells obtained from another location. These phenomena lead to a high percentage of healing. (see below images of our minimally invasive technique for the treatment of avascular necrosis in early stages).
Another option is the introduction of a bone fragment (iliac-fibula crest with its nutritive artery by microsurgery.) Although long-term interventions, the application of vascularized bone grafts of both iliac crest, fibula, and rib, provide an acceptable success rate.
In them the femoral head sinks and rapid wear occurs because it has lost its sphericity. In this case we have to resort to arthroprotic techniques with very good success, already explained in hip arthrosis of the young adult and osteoarthritis of the major. (see radiographs, magnetic resonance and case treated with surface prosthesis in a young adult with advanced degree of avascular necrosis of the femoral head).
