The following is a list of generalized causes: Infection at the woundPressure on suturesSutures too tightInjury to the wound areaWeak tissue or muscle at the wound areaIncorrect suture technique used to close operative areaPoor closure technique at the time of surgeryUse of high-dose or long-term corticosteroids
