Quick pearl for those that are trying to complete their holiday shopping.
Mulder's sign is not a sign that there is an extra-terrestial in your ED, But rather a sign that your patient is suffering from a Morton's Neuroma (see pearl from 2012)
Patients will often complain of pain in 3rd and 4th intermetatarsal space and if you can reproduce the pain by compressing the metatarsal heads together then you have a Positive Mulder's sign. Check out the original pearl at https://umem.org/educational_pearls/1684/
