What test is indicated by a clicking sensation when palpating the 3rd and 4th metatarsal joints?

The indicated test for a clicking sensation when palpating the 3rd and 4th metatarsal joints is known as the Mulder sign. This test is specifically designed to assess for the presence of a Morton's neuroma, which is a thickening of the tissue around a nerve leading to the toes. The clicking sensation that occurs during the test is due to the compression of the affected nerve between the metatarsal heads, producing the characteristic symptoms associated with Morton's neuroma.

During the Mulder sign test, the examiner typically applies pressure on the metatarsal heads and squeezes the forefoot. If a click is felt as the metatarsals are compressed, it suggests the presence of a neuroma. This test is particularly relevant for individuals experiencing pain or discomfort in the forefoot and is a valuable tool in diagnosing this specific condition.

The other tests mentioned assess different conditions and are not relevant to the symptom described. The Thompson test evaluates for Achilles tendon rupture, Tinel's sign is used to assess for nerve irritation (often associated with carpal tunnel syndrome), and Homan's sign is used to check for deep vein thrombosis in the legs. Each of these serves a different purpose and does not relate to
