Trapeziometacarpal joint instability is a well-recognised but under-diagnosed cause of basal thumb pain. A systematic approach with sound understanding of anatomy and clinico-pathological correlation is required to make a diagnosis.

An evaluation algorithm for Eaton's injury of the thumb is proposed for clinical application with evidence in literature.
