Nails are submitted to a lot of trauma in the everyday life; their response to these traumatisms is various and they show themselves in misleading clinical manifestations leading often to misdiagnosis such onychomycosis or nail pathology of another origin. As for toenails dystrophies, repeated microtraumatisms in the shoes are the main cause and these dystrophies often reveal biomechanical disorders. As for fingernails, except the occupational pathology which is not related in this paper, nails dystrophies are particularly self-inflicted due to an obsessional-compulsive disorder. We are describing here the different nails dystrophies of mechanical aetiology, the different original factors and their mechanisms, as well as signs leading to the diagnosis.
指甲在日常生活中会遭受许多创伤；它们对这些创伤的反应多种多样，并表现为具有误导性的临床表现，常常导致误诊，如甲癣或其他原因引起的指甲病变。至于趾甲营养不良，鞋子里反复的微创伤是主要原因，这些营养不良常常揭示生物力学紊乱。至于指甲，除了本文未涉及的职业性病变外，指甲营养不良尤其因强迫症而自我造成。我们在此描述机械性病因导致的不同指甲营养不良、不同的原始因素及其机制，以及诊断依据。
