Case report - Reconstruction of a bone defect resulting from postoperative complications following acetabular osteosynthesis with an individualized implant

We present the case of a 43-year-old patient who suffered trauma in a car accident while suffering a fracture of the posterior wall of the acetabulum. He was initially surgically treated at a general hospital with osteosynthesis of the posterior wall of the acetabulum. In the postoperative period, complications occurred in the form of fracture dislocation and displacement of the osteosynthetic implant with signs of infection and AVN of the femoral head. In the same institution, a resection of the femoral head was performed, implants were removed and a spacer was placed. Due to the above complications of treatment, he was referred to the University hospital for traumatology of the KBC Sestre milosrdnice. Initially, a CT scan was performed which showed a defect in the posterior wall of the acetabulum involving about 50% of the articular surface. Due to the above, we assessed that the existing defect could not be compensated with standard implants, and we decided to plan the production of an individualized acetabulum implant. During the surgery, an individualized acetabulum and revision stem were implanted. In the postoperative period, the patient walked with crutches for 6 months, three years after the procedure there are no signs of complications and he is pain-free. The production of an individualized implant requires a longer period of time (about 3 months) with a high cost. In the case of major acetabulum defects, an individualized implant is one of the choices for the treatment of bone defects.
