This complex intervention includes several steps:
- Prosthesis and cement ablation
- Anycompletion with grafts to fill the bone destruction wounds.
- Mounting a new prosthesis.
- Bone strengthening around the prosthesis by complementary synthesis.
Bone grafts are sometimes necessary in the acetabulum. Bone at the tissue bank is mixed with bone grafts taken while preparing the prosthesis seat. Sometimes, a metal support can be used, aimed at graft stabilization and acetabulum strengthening, to cement the implant.
Femur fracture in a patient with hip prosthesis
– Complete cement extraction in the femurcan sometimes be difficult, with significant risks of fractures and cortical perforation. To have a quality stabilisation of the fragile area,elongated femoral stems are often necessary, crossing the fragile area, to anchor in the healthy bone. Uncemented prostheses are preferred in these cases.
Surgical consequences are a bit more complex than in case ofnormal prosthesis, often prohibiting support for several weeks, but the final results are very good with complete function recovery. Length of hospitalization is prolonged, sometimes requiring rehabilitation (before returning home).
La reprise d’une prothèse de hanche reste une intervention compliquée, même dans les mains de chirurgiens confirmés, avec des complications de fréquence supérieure aux prothèses de première intention.
