There are many different types of foot wound dressings on the market to choose from. Choice of foot wound dressings will depend on size and location of wound, infection, fluid levels, allergies and surrounding skin integrity.
The dressing will have to undergo increased friction and pressure than anywhere else on the body. Therefore it is important to use a suitable dressing choice.
The Ideal Properties for Foot Wound Dressings:
- Provides a moist wound environment.
- Provide protection to the wound bed.
- Sops infection getting in.
- Leaves no materials behind in the wound.
- Non-toxic, non-allergenic and non-irritating.
- Promotes wound healing.
- Does not stick to the wound or to the surrounding skin.
- Allows for removal without pain or trauma.
- Capable of absorbing excess fluid without coming through the dressing.
- Antimicrobial if clinical signs of infection need to be treated.
- Needs to be easy to use and cost effective for patient.
Below is a list of some of the wound dressings currently available. Please note that consultation with a medical practicioner or treating podiatrist is advisable before purchasing dressings. This is to ensure you have the correct dressing for your foot wound.
Gauze
- Sterile gauze is beneficial for loosely packing wounds that are very deep.
- Used mainly as a secondary dressing.
- Can stick to the wound bed and cause trauma on removal if too dry, so needs to be wet to remove.
Tulle (Jelonet);
- Does not stick to wound surface, so no irritation is caused on removal.
- Suitable for flat, shallow clean wounds.
- Useful in patients with sensitive skin.
- e.g basic cuts and scratches.
Hydrocolloids (DuoDerm, Tegasorb);
- Non- breathing dressing, so do not use with infection.
- Promotes cleaning of the wound and healing.
- For wounds with light to heavy fluid levels, sloughing or granulating wounds.

Cadexomer Iodine (Iodosorb);

Among all these dressings I had used Alginate Dressings and on the basis of my personal experience, I would say it is a really good dressing. I have purchased it from
https://www.wound-care.co.uk/cutimed-alginate-dressings.html
I am a 78 year old woman with a venous wound on my foot around the ankle bone. An MRI scan has revealed no osteomyelitis and that the wound is shallow with slight granulation. I am using Aquacel but find this painful to remove unless really wet. i.e taking a shower. Your article has mentioned a new dressing Altrazeal. Is this available in England please? The wound originally began years ago after an accident but has cleared up several times. I suffer from rheumatoid arthritis and take Methotrexate and infusions of Rutiximab. I should welcome any advice you can give as this is really impeaching my life. kind regards
HI Valerie,
Thank you for your comment. Altrazeal is available in most of Europe but I am unsure about the UK. My advice would be to ask your local doctor, treating specialist and/or pharmacist if they are able to source the product. You could also try contacting local wound care dressing suppliers to see if they stock it? You may also be able to purchase the product online. If you are under a vascular specialist, they would be the best person to ask initially. I wish you all the best of luck with locating the product. If you have any further questions please do not hesitate to ask.
Warmest Regards

Somehow I feel gel dressings are the best as they not only heal but also easy to maintain. Thus, they are best for woundcare.
I agree gel dressings are great in wounds with low levels of exudate.
Great stuff, very informative! Hydrogels or hydrocolloids and Alginate dressings are good for leg and foot ulcers.
