A 64-years-old male with left hip pain.
(A) Preoperative radiograph shows the non-union of pertrochanteric fracture with broken angle blade plate.
(B) Immediate postoperative radiograph shows dynamic hip screw fixation due to the inferior head defect. During the re-fixation, bone graft was added due to the bone defect on the non-union site.
(C) Radiograph after one year shows solid fracture union.
Fig. 3
A 69-years-old male with left hip pain.
(A) Preoperative radiograph shows infected non-union of fracture site with large bone defect.
(B) After infection control, 90 degree angle blade plate was used due to the superior head defect. During the re-fixation, bone graft was done.
(C) One year after the operation, the fracture site was well united.
