A wound is any type of damage or breakage on the surface of the skin. The wounds can be due to accidents like burns, paper cuts, skin tears or surgical, any underlying disease, or some other skin conditions that may develop in the wound, for example, eczema or psoriasis.

Types Of Wounds

Wounds can be classified in several ways depending on the healing time and the necessity to consult with Wound Care Specialists depending on the severity of a particular wound. People are likely to suffer from different types of wounds throughout life while performing daily activities. Depending on the cause, site, and depth, a wound can lead from simple to severe one. Here, we have explained different types of wounds. Let's have a look:

  • Open or Closed - Wounds can be open or closed. Open wounds are the wounds with exposed underlying tissue/ organs and open to the outside environment, for example, penetrating wounds. On the other hand, closed wounds are the wounds that occur without any exposure to the underlying tissue and organs.
  • Acute or Chronic - A wound can be classified as acute or chronic depending on the healing time. Acute wounds are those that heal without any complications in a predicted amount of time. While chronic wounds, on the other hand, are those that take a relatively long time to heal with some complications.
  • Acute or Chronic - A wound can be classified as acute or chronic depending on the healing time. Acute wounds are those that heal without any complications in a predicted amount of time. While chronic wounds, on the other hand, are those that take a relatively long time to heal with some complications.

Types of Chronic Wounds

Pressure Injuries - Also known as bedsores, pressure sores, or decubitus ulcers, these wounds cause when there is a pressure and/or shearing force on the skin. The people who are more prone to these chronic wounds are with limited mobility due to any medical illness or unable to walk, move all or part of their body to a different position.

Diabetic Ulcers - These ulcers generally occur on the feet and are a result of changes to nerves and circulation in the body caused by diabetes. It includes Neuropathic, Ischemic, and Neuro-ischemic.

Clean or Contaminated - Wounds can also be classified on the basis if they are clean or contaminated. Clean wounds are those that do not have any foreign material or debris inside whereas contaminated wounds or infected wounds are those that might have some dirt, bacteria, or other foreign markets. Pressure wounds can be used as an example of an open or closed wound depending on its current stage.

Internal or External - Wounds can also be internal or external. Internal wounds can be due to impaired circulation, nervous system functions, neuropathy or medical illness, or decreased supply of blood, oxygen, or other nutrients while the external wounds can be due to an outside force or trauma caused by penetrating objects or non-penetrating trauma.

Non-penetrating Wounds: - These wounds are the result of blunt trauma or friction with other surfaces. It includes:

  • Abrasions
  • Lacerations
  • Bruises
  • Concussions

Penetrating Wounds: - They are the result of trauma and break through the full thickness of the skin. It includes:

  • Stab wounds
  • Cuts 
  • Surgical wounds etc.

Each type of wound has a different approach and method of treatment.

Arterial Ulcers

Arterial insufficiency ulcers, Ischemic ulcers, Ischemic wounds are common wounds located on the lateral surface of the ankle or side of the foot caused by poor perfusion to the lower extremities.


First, second and third degree burns caused by any source- heat, chemicals, or electricity that damages the body’s tissues.

Chronic Wounds

Any wound that does not heal in a predictable pattern, way or within the normal amount of time. Depending on the type of wound typical healing patterns follow certain healing timeframes. Wounds that heal outside of these timeframes are classified as chronic and/or non-haling wounds.

Deep Vein Thrombosis (DVT)

Deep Vein Thrombosis (DVT) is a blood clot that forms most often in the leg in the deep veins. Symptoms include swelling, warmth, redness, and pain in the leg. This condition can lead to difficult to heal wounds.

Dermal Lesions

Dermal Lesions are skin growths on top of your skin.

Diabetic Ulcers

Diabetic Ulcers are open skin wounds associated with diabetes.

Foot Wounds

Any and all open sores or lesions on your feet.


Gangrene is when blood flow to a certain area of the body is cut off. It is a serious condition that causes the tissue to breakdown and die.

Infected Wounds

An infected wound is any wound that contains bacteria or other micro-organisms causing delays in healing.

Limb Salvage

As an alternative to amputation, we treat and help save what we can to preserve your limb with aggressive therapies.

Moisture-Associated Skin Damage

Moisture-associated skin damage (MASD) is a wound caused by prolonged exposure to various sources of moisture including but not limited to perspiration, wound exudate, urine, stool, mucus, and saliva.

Necrotic Wounds

Necrotic wounds are wounds that have dead tissue.

Non-Healing Wounds

All wounds that are difficult to heal and do not progress the way a typical wound should are classified as non-healing.


Wounds resulting in the bone being exposed and leading to infection in the bone.

Pressure Ulcers

Pressure sores are areas of damaged skin caused by staying in one position for too long. We treat all stages of pressure ulcers.


Pyoderma gangrenosum (PG) is an inflammatory skin disorder that is characterized by small, red bumps or blisters that, over time, erode the skin to produce swollen open sores.

Radiation Dermatitis

A skin condition that is caused from large external doses of radiation.

Radiation Skin Injuries

Also called radiodermatitis, this condition is caused by prolonged exposure to ionizing radiation.

Skin Graft Donor Sites

Skin Graft Donor sites are wounds created by harvesting skin for skin grafting.

Skin Lacerations

Cuts, tears, and breaks in the skin in various depths.

Soft Tissue & Bone Infections

Skin and soft tissue infections (SSTIs), which include infections of skin, subcutaneous tissue, fascia, and muscle and have clinical presentations ranging from simple inflammation to necrotizing fasciitis.

Surgical Wounds

Surgical wounds are wounds from prior surgeries that have opened up or not healed.

Traumatic Injuries

A Traumatic injury refers to physical injuries with a sudden onset. These injuries can range from lacerations, hematomas, to open wounds.

Tunneling Wounds

A tunneling wound is any wound that channels or tunnels from the wound through surrounding muscle or subcutaneous tissue.

Vasculitis (Rheumatoid Arthritis, Lupus/SLE)

Vasculitis is the inflammation of blood vessels that can lead to wounds.

Venous Stasis Ulcer

A venous stasis ulcer is caused by the drainage of fluid as a result of poor venous circulation. These ulcers occur in the lower legs, between the knee and the ankle.

Work-Related Injuries (Workman's Comp Injuries)

We treat any work related wounds.

Classification of wounds

There are many different ways in which wounds can be classified. In many cases, a wound may consist of a combination of the different classifications.

1. Wound thickness
Superficial Involves only the epidermis and the upper dermis
Partial thickness Involves skin loss up to the lower dermis
Full thickness Involves skin and subcutaneous tissue
Deep and complicated Involves penetration into natural cavities, an organ or tissue
2. Wound complexity
Simple Affecting only one organ or tissue
Combined Affecting multiple organs and/or tissue
3. Wound age
Fresh Up to 8 hours from the time of injury
Old After 8 hours from the time of injury
4. Wound origin
Superficial Breaking the skin’s surface from scratching, rubbing, picking, or a graze from falling
Incised Usually as a result of surgical intervention
Crush Made with a heavy blow of a cutting tool, such as a hatchet, sword
Lacerated Fragments of tissue torn away with a sharp-edged object
Lacerated Fragments of tissue torn away with a sharp-edged object
Stab Made with a pointed tool or weapon
Contused Injury to tissue under the skin's surface, most common type of wound seen in traffic accidents
Secondary Wounds originating from primary diseases, such as diabetic ulcers, pressure ulcers, venous ulcers
Other Bullet wound, bite wound, poisoned wound

Wound healing

The process of wound healing involves three overlapping phases:

  • Inflammation – involves scab formation and infiltration of damaged tissue by white blood cells. These are responsible for removing dead tissue and ingesting bacteria.
  • Proliferation – involves the development of granulation tissue, contraction of the wound and growth of epithelial cells under the dried scab.
  • Maturation – wound becomes less vascular and is strengthened by the rearrangement of collagen fibres.

The rate at which a wound heals is dependent on several factors. These factors need to be considered before deciding on the method(s) used to treat a wound. Factors to consider include:

  • Position and size of the wound
  • Tissue type (eg, sloughy, necrotic, granulating)
  • Amount of exudate
  • Presence or absence of infection
  • Presence or absence of pain

Wounds heal fastest if they are attended to as quickly as possible after an injury. The aim should be to dress or close the wound using appropriate methods to keep it free from infection and to create an environment that promotes healing.
