(A) This patient suffered from left hip pain associated with rheumatoid arthritis showing severe osteoporosis with wide medullary
canal.
(B) Prophylactic cerclage band and wires were used to prevent the intraoperative periprosthetic femoral fracture.
(C) Postoperative radiograph at six months shows stably fixed prosthesis in medullary canal.
Fig. 2
(A) Preoperative radiograph showed loosening of cemented stem and massive osteolysis combined with severe osteopenic femur.
(B) Type C3 fracture occurred during insertion of provisional prosthesis intraoperatively.
(C) The fracture fixed with wires and bands with uncemented long stem prosthesis was united.

(A) A type AG fracture.
(B) The fracture fixed with hook and cables was united.

(A) A type B1 fracture.
(B) The fracture was treated using plate with proximal cables and distal bicortical screws. The radiograph shows fracture united and a stable prosthesis.

(A) A type B2 fracture.
(B) The fracture was treated with an uncemented long-stem prosthesis 3 bandages and 1 wires. The radiograph demonstrates good healing of fracture with stable prosthesis.

(A) The anteroposterior radiograph of type B3 fracture reveals a loose prosthesis associated with deficient proximal lateral cortex.
(B) The fracture was treated with an uncemented long-stem prosthesis and plate with 4 cables with allograft. The radiograph demonstrates good healing with graft incorporation.

(A) The AP radiograph shows type B3 fracture with severe proximal bone loss.
(B) Postoperative radiograph at second week shows that fracture is reduced and fixed with plate (supplementary fixation and additional allograft), but does not show fully restored bone stock.
(C) Postoperative radiograph at 26 months shows varus shift of stem.
Fig. 9
(A) The anteroposteriorradiograph shows type B3 fracture.
(B) Postoperative radiograph at second week shows that fracture is stably fixed with plate, screws and cerclage wire, and remaining stem is stably fixed as well.
(C) Postoperative radiograph at one year shows good healing of fracture with stable prosthesis.
