Sciatic nerve palsy is the most common nerve injury associated with acetabular fracture and dislocation, but femoral nerve injury is known to be very rare because of relative protected position of nerve between the iliacus and psoas muscle, and as far as we know only one report was noted in English about combined femoral and sciatic nerve injury associated with acetabular fracture and dislocation, so we hereby report a case of combined femoral and sciatic nerve palsy associated with acetabular fracture and dislocation.
