BERNAL-MACIAS, Santiago  and  GUALDRON-CHAPARRO, Karen. Interosseous atrophy beyond rheumatoid arthritis, a manifestation of amyotrophic lateral sclerosis. Rev.Colomb.Reumatol.

Interosseous atrophy of the hand is not an exclusive finding of rheumatoid arthritis, and in the case of amyotrophic lateral sclerosis it has a significant diagnostic and prognostic value. The physical examination and evidence of the "split hand" sign or sign of the double anatomical snuffbox is a finding that should alert the clinician to the need for complementary studies in order to rule out neurological pathology.

Keywords : Amyotrophic lateral sclerosis; Sign of the anatomical double snuffbox; Split hand.
