What is the danger in doing a turned lateral on a impacted subcapital fracture?
There is a risk of displacing a previously undisplaced fracture and turning conservative treatment into an operative procedure, or, more likely turning cannulated screws into a DHS with the increased associated risks.
What are the two main visual clues to the fracture site ?
Increased sclerosis across the femoral neck and loss of congruity of superior border of neck of femur. Comparison with contralateral side makes this more obvious.
Impacted subcapital fracture of the left neck of femur is demonstrated.
