Intra-operative Vancouver subtype B3 PFF. A B3 PFF occurred during hip dislocation for THA in an osteoporotic patient. The diaphyseal component of the fracture was synthetized with multiple cerclages and an uncemented diaphyseal-fitting modular stem was implanted. After that, suture wires were used to stabilize the greater and the lesser trochanters to the proximal body of the prosthesis.
