Q

What are the implications of femoral fracture location with regards to outcome and treatment?

A

The location affects whether blood supply was compromised and thus what type of repair is appropriate. If the blood supply was not irreversibly damaged, then it is possible to put in fixation to allow natural healing. If the blood supply is too severely damaged, full prosthetic replacement may be necessary.
