Pain in the knee

This gent had a fall and then some knee pain.  His knee seemed pretty good on clinical exam and so very sensibly people asked questions about his hip too.  This was the view on his long femur Xray.  What do you think?

This is an undisplaced intracapsular fracture, often called an impacted subcapital fracture.  They sometimes get missed and then present a week or two later having "fallen off".  The treatment is the same as for any intracapsular fracture in the elderly - a hemiarthroplasty.  In young people presenting acutely, intermedullary screw fixation is also an option.

​The shenton's lines again are the giveaway here.  If you're not sure about them, have a refresh of the old post here.
