Common causes of chronic wounds

Information is crucial to getting better. At San Ramon Regional Medical Center, we work hard to stay current on the causes of chronic wounds, and below you’ll find information you may need to know.

Bone infections

Osteomyelitis is a bone infection. It can occur in individuals of all ages and is the result of a bacterial infection that reaches the bones.

Diabetic foot ulcers

Diabetes increases the chances of an individual developing an ulcer or sore on the feet. Diabetic sores are often painless and a common cause of hospitalization in diabetics.

Failing skin and muscle grafts

Muscle and skin graft surgeries are not always successful. When there is a limited supply of blood to the area, the graft may fail and patients may require a second surgery.


Gangrene is the result of infection or lack of blood flow to a particular region of the body. This leads to dead tissue.

Immunosuppressive disorder wounds

These wounds are associated with a number of immunosuppressive disorders, including diabetes, HIV and cancer. These wounds are often a complication from having a compromised immune system.

Lower leg ulcers

Ulcers are opened wounds or sores that will not heal, or heal and continue to return. Lower leg ulcers may or may not be painful and are typically found on the inner portion of the leg just above the ankle.

Post-operative infections

One type of surgical complication is a post-operative infection. Post-op infections can be the result of longer surgeries, wounds that become dirty, obesity or age.

Radiation burns

Radiation burns are damage to the skin or other tissues caused by exposure to radiation. Patients undergoing radiation therapy for cancer may experience these types of burns.

Skin tears and lacerations

A laceration occurs when the skin is cut. Lacerations tend to be deep and often require medical care, such as stitches, to repair them.

Slow- or non-healing surgical wounds

Not all surgical wounds heal quickly or completely. The most common reason for this is infection at the site of surgery.
