Ingrown Toenails
Ingrown nail (also known as an "
Onychocryptosis ,") is a common form of
nail disease. It is an often painful condition in which the
nail grows so that it cuts into one or both sides of the
nail bed. While
ingrown nails can occur in both the
nails of the hand and
feet, they occur most commonly with the
toenails.
The main cause for
Ingrown nail (
Onychocryptosis ) is improper footwear including shoes with inadequate toe-box room and tight stockings that apply top and or side pressures; next is the damp wet atmosphere
toes are subjected to all day in enclosed shoes, softening the nail-plate and swelling the epidermis keratin, which eventually increases the convex arch permanently; next is genetics; and last are
trauma and disease.
Improper cutting of any
nail may cause the
nail to cut into the side-fold skin from growth and impact, whether or not the
nail is "ingrown" (
Onychocryptosis ). The
nail bends inwards or upwards depending on the angle with which it has been cut. Looking from the perspective of the owner, when cutting the
nail, if the cutting tool, such as scissors, are in an attitude where the lower blade is closer to the
toe than the upper blade then that will cause the
toenail to start growing from its base upwards. Vice versa, when the lower blade is farther than the upper blade, the
toenail will turn inwards. The process is visible along the
nail as it grows, appearing as a warp that advances towards the end of the
nail. The upper corners turn more easily than the center end of the
nail. As people cut their
nails by holding the tool always in the same angle, they induce these conditions by accident, while as the
nail turns closer to the skin, it becomes harder to fit the lower blade in the right attitude under the
nail. When cutting a
nail, it is not just the right angle that is important, but also how short it is cut. A shorter cut will bend the
nail more, unless the cut is even on both top and bottom of the
nail.
Causes include:
- Bad maintenance, including cutting the
nail too short, rounded off at the tip or peeled off at the edges instead of being cut straight across
- Ill-fitting shoes, as those that are too narrow or too short can cause bunching of the
toes in the developmental stages of the
foot (frequently in those under 21), causing the
nail to curl and dig into the skin
-
Trauma to the
nail plate or toe, which can occur by stubbing the
toenail, dropping things on the
toe or going through the end of the shoes (as during sports or other vigorous activity), can cause the flesh to become injured and the
nail to grow irregularly and press into the flesh
- Predisposition, such as abnormally shaped
nail beds,
nail deformities caused by diseases, or a genetic susceptibility to
nail problems like ingrowth
A more physiologically sound hypothesis is that an "
Ingrown Toenails " is actually a problem where there is too much skin around the
nail ("Overgrown Toeskin") - the
nail is not the problem. Vandenbos and Bowers theorized that pressure necrosis of the soft tissues surrounding the
nail due to weight bearing is the primary cause of ingrowing toenail. They wrote "the term '
ingrown toenail ' is unfortunate in that it incriminates the
nail as the causative factor and is responsible for the fact that most operative and conservative treatments are directed toward the
nail. It is our thesis that persons who develop this condition have an unusually wide area of tissue medial and lateral to the
nail and that with weight bearing this tissue tends to bulge up around the
nail. When such persons trim the
nail in a curved or rounded fashion instead of straight across, further bulging of soft tissue is allowed, and as the
nail grows out, pressure necrosis of soft tissue occurs. If our thesis that the fault lies not with the
nail but with an excess of soft tissue is correct, treatment by removal of a segment of
nail is not rational. It increases the relative amount of soft tissue and predisposes to recurrence and at the same time inept attempts to remove some
nail matrix lead to faulty regrowth of the
nail. The logical conclusion is that soft tissue should be excised, so that with weight bearing there will be no tissue to bulge up across the
nail."
One study compared patients with
ingrown toenail to healthy controls and found no difference in the shape of
toenails between patients and controls and suggested that treatment should not be based on the correction of a non-existent
nail deformity.
Ingrown toenail are caused by weight-bearing (activities such as walking, etc.) in patients that have too much soft tissue (skin) on the sides of the
nail. Weight bearing causes this excessive amount of skin to bulge up along the sides of the
nail. The pressure on the skin around the
nail results in the tissue being damaged, resulting in swelling, redness and
infection.
In the past (and still today) the most common treatments are mainly directed at the
nail (Paradigm Paralysis). Treatments often include removal of part or all of the
nail. But since the
nail is normal and the problem of too much skin around the
nail is not treated, this often results in the problem returning or in deformity/mutilation of the
nail. Not surprisingly, patient satisfaction reflects this.
Symptoms of an
ingrown nail include pain along the margins of the
nail (caused by hypergranulation that occurs around the aforementioned region), worsening of pain when wearing shoes or other tight articles, and sensitivity to pressure of any kind, even the weight of bed sheets or a duvet. Bumping of an affected
toe with objects can produce sharp, even excruciating, pain as the tissue is punctured further by the
ingrown nail . By the very nature of the condition,
ingrown nails become easily infected unless special care is taken to treat the condition early on and keep the area as clean as possible. Signs of
infection include redness and swelling of the area around the
nail, drainage of pus and watery discharge tinged with blood. The main symptom is swelling at the base of the
nail on whichever side (if not both sides) the ingrowing nail is forming.
The most common place for
ingrown nails is in the big
toe, but ingrowth can occur on any
nail.
Ingrown nails can be avoided by cutting
nails straight across;
nails should not be cut along a curve, nor should they be cut too short. In both cases, the important thing to avoid is cutting the
nail shorter than the flesh around it. Footwear which is too small, either in size or width, or those with too shallow a 'toe box' will exacerbate any underlying problem with a
toenail.
It may not be so critical that the
nails be cut perfectly 'straight across' as this may imply that they be squared at the corners. Leaving sharp square corners may be uncomfortable and cause snagging on socks. The important thing to keep in mind is that you want to be able to see the corners. You should be able to see the side edge of the
nail as it meets the front edge of the
nail. This way, you can be sure there is no 'splinter' veering off to the side and growing into your
toe. Careful filing of the corner is reasonable. For some people the
nail curves down on the sides, in this case it would be difficult to ever see the side edge of the
nail plate and this cutting method does not apply. Some
nails require cutting of the corners far back to remove the edge that digs into the flesh, this may be done as a partial wedge resection at your podiatrist's office.
Ingrown toenail can be caused by injury, commonly blunt
trauma where the flesh is pressed against the
nail causing a small cut that swells. Also, injury to the
nail can cause it to grow abnormally, making it thicker or wider than normal or even bulged or crooked. Stubbing the
toenail, dropping things on the
toe and 'going through the end of your shoes' in sports are common injuries to the digits. Injuries to the
toes can be prevented by wearing properly fitting shoes, especially when working or playing.
One myth is that a V should be cut in the end of the
ingrown nail; this myth is untrue. The reasoning of the myth is that if one cuts a V in the
nail, the edge of the
nail will grow together as the
nail grows out. This does not happen - the shape of the
nail is determined by the growing area at the base of the
toe and not by the end of the
nail. A notch does no good, and may do harm if it is cut too deeply.
Treatment of
ingrown nails ranges from soaking the afflicted area to surgery. The appropriate method is dictated by the severity of the condition. In nearly all cases, drainage of blood or watery discharge should mean a trip to the doctor, usually a podiatrist, a specialist trained explicitly to treat these conditions. Most practitioners agree that trying to outwait the condition is nearly always fruitless, as well as agonizing, but it can be done as long as the condition is not too severe and if the individual has a high pain threshold.
In mild cases (not including the severe cases as in the photos above), doctors recommend daily soaking of the affected digit in a mixture of warm water and Epsom salts and applying an over-the-counter antiseptic. This might allow the
nail to grow out so it may be trimmed properly and the flesh to heal. Note that
infection may be somewhat difficult to prevent in cleaning and treating
ingrown nails owing to the warm, dark, and damp environment in shoes.
Peroxide is immediately effective to help clean minor
infections but iodine is more effective in the long term as it continues to prevent bacterial growth even after it is dry. However, iodine should not be used on deep wounds. In such cases a physician or podiatrist should be consulted. Also, although bandages can help keep out bacteria, one should never apply any of the new types of spray-on bandages to
ingrown nails that show any discharge - preventing drainage will likely cause intense swelling and pain. Removal of spray-on bandages can be achieved with common rubbing alcohol.
Another effective method is to use a toothpick or other small pointed object to stuff a very small piece of cotton under the
nail, specifically the affected area or as close to it as possible. In mild or moderate cases this may help the
nail to grow back out from underneath the skin.
Some doctors will apply silver nitrate to granulation tissue (overgrowth of irritated tissue at the side of the
nail. This may look like reddish cauliflower, bleeds easily). This may shrink and or remove this sensitive overgrown tissue at the side of the
nail.
Another way to deal with the
ingrown toenail is to get half of your
toenail which is growing under the skin removed.This is a painless procedure after you receive your local
anesthetics. The doctors remove half the
nail and pour a liquid onto the skin which kills the roots and any chance of the
nail growing back.
Never ever attempt to alleviate the swelling using a needle, doing so can lead to an
infection.
These home remedies are, in serious cases, ineffective: when the flesh is too swollen and infected these procedures (purple skin around natural skin tone) will not work. Thus, these more severe cases, such as when the area around the
nail becomes infected or the
nail will not grow back properly, must be treated by a professional.
