Abstract

We report the first case of a complex regional pain syndrome (CRPS) limited to the hallux using the Budapest criteria. Limited forms of CRPS are scarce in the literature and probably overlooked. There is currently no consensus to define these forms. Due to the particular metameric topography, common to the hand and the foot, we suggest the term 'metameric' CRPS to describe them. A uniform nomenclature would promote future research to study its prevalence and specific treatment in more detail.

Keywords: anxiety disorders (including OCD and PTSD); musculoskeletal and joint disorders; musculoskeletal syndromes; pain; rehabilitation medicine.
