Penetration of Ullevaal hip screw into the pelvis.
The fracture of the femoral neck is usually treated operatively with screw osteosynthesis or prosthesis. There have been reported a rare complication both with screws and lag screws used in hip fractures, both can penetrate into the pelvis postoperatively. We present two cases with this similar rare complication when using Ullevaal screws. Both patients were reoperated on with a total hip arthroplasty (THA). We think that the exact anatomical reposition and good operation technique should make this complication even more rare. The canal should always be drilled only to the line of the fracture, so that there is no canal for the screw to squeeze further. To prevent penetration some kind of cap fixed the lateral end of the screw could also be worth while.
