Xray of 83 years old lady with intertrochanteric fracture fixed with dynamic hip screw assembly and showing protrusion of the lag screw beyond the head margin.
The xray is done after 1.5 years of surgery and fracture is well united. Osteoporosis of the bones is quite visible.
Lag screw is the thick screw in the head. If you note carefully, it is protruding beyond the margins of the head.
The assembly was removed because patient had pain on weight bearing.
