title: [Hypermobility of the first ray associated with osteonecrosis-fracture of the tarsal navicular bone].
abstract: Is an increase in medio-plantar strain the common denominator in Köhler disease and in stress fractures of the tarsal navicular? This hypothesis is illustrated by the present observation where the increase in strain is provoked by constitutional articular laxity.
