[2] [3] To overcome that stage and jump-start the healing process, a number of factors need to be addressed such as bacterial burden, necrotic tissue, and moisture balance of the whole wound. [4] In acute wounds, there is a precise balance between production and degradation of molecules such as collagen ; in chronic wounds this balance is lost ...

Some complications include autonomic dysreflexia, bladder distension, bone infection, pyarthrosis, sepsis, amyloidosis, anemia, urethral fistula, gangrene and very rarely malignant transformation (Marjolin's ulcer – secondary carcinomas in chronic wounds).
Passive smoking also impairs a proper wound healing process. [66] Age – Increased age (over 60 years) is a risk factor for impaired wound healing.
