Many pathologies are the result of misconceived management. The preferred term is here is 'misconceived' because management is not always poor or inadequate; a structure can be well maintained and in good condition and the horses well treated. Clearly this is not always the case and truly poor or inadequate management tends to indicate shortcuts and outright maltreatment. Such circumstances will always exist simply because of the human desire to exploit.
Misconceived management is more a case of technically well cared for –going by the book, believing to be doing the best possible for the horse– but failure because in practice the techniques applied are not truly adapted to the real needs of the horse.
Emphatically, not all pathologies but many are a result of misconceived management. Clearly laminitis resulting from the horse escaping and devouring the neighbour's grain store is more accidental than misconceived - the more so if all possible precautions have been taken to keep the horse in check and a third party leaves a gate open, for instance.
