Indications

Morton’s Test is an ankle examination procedure that tests for the presence of Morton’s neuroma, arthritis of the metatarsal joints, fracture of the metatarsal heads or stress fracture.

Procedure

Patient should be awake and cooperative during a Morton’s test.

  1. Patient may be supine or seated during this test.
  2. The examiner squeezes the foot around the metatarsal heads and checks for any signs of discomfort or pain.

The examiner squeezes the metatarsal heads and checks for pain.

Interpretation

Positive Morton’s Test

There is positive Morton’s test when there is pain upon squeezing the metatarsal heads. This sign indicates the presence of Morton’s neuroma, metatarsal joint arthritis or fracture or stress fracture

Clinical Notes

Morton’s neuroma usually occurs between the distal metatarsals (between #3-4 55%, between #2-3 45%).

Differential diagnosis:

  1. Metatarsalalgia pain is less localized with pain under the metatarsal heads (paresthesia is not present).
  2. Stress fracture pain localized to metatarsal shaft – not between metatarsals.
  3. Deep peroneal neuropathy – signs and symptoms between the first and second toe.
