Subungual Hematoma Growing Out

Subungual Hematoma Growing Out If left untreated, a simple subungual hematoma typically grows out with the lengthening nail plate and resolves on its own, although sometimes subungual hematomas can result in your nail falling off (onycholysis). Until the nail grows out, however, you can expect weeks to months of blue-black discoloration.

It can take up to 9-12 months for a subungual haematoma on the toenail to fully grow out. However, if there is severe damage to the nail bed, the nail may grow back disfigured or sometimes there is little to no nail regrowth at all.

A subungual hematoma can range from a small spot under the nail to a large area of discoloration. Depending on the amount of blood beneath the nail, the nail may come loose. But often the nail does stay intact, and the blood fades as the nail grows out.

With subungual hematoma, injury to the nail results in bleeding (hematoma) at the level of the nail bed (under the nail plate) or nail matrix. The nail matrix is a rapidly dividing layer of cells at the base of the nail lying toward the cuticle. Rapidly dividing cells of the nail matrix fill with keratin and thus become a hardened nail.

Treatment for subungual hematoma. Once the pressure is relieved, most people get immediate relief. The damaged nail will most likely fall off on its own if it isn’t removed by your doctor, which may happen if it’s badly damaged. Whether your nail is drained or not, it’s important to watch for signs of infection.

Healing of the skin underneath the nail often takes no longer than a couple of weeks after the injury, if the blood is not drained shortly after the incident it will dry up and leave a dark/black discolouration to the nail which has to grow out. It can take up to 9-12 months for a subungual haematoma on the toenail to fully grow out.

Regardless of treatment the hematoma will eventually be resorbed by the body and a new nail will grow out. On average the nail takes 6 to 9 months to grow completely out. A complication to be aware of is damaging the cells that re-grows the nail (the nail matrix).

After the subungual hematoma is drained, the pressure beneath the nail is relieved, and the pain decreases significantly. The hole formed in the nail will remain and grow out at the rate that the nail normally grows. One possible risk and long-term complication of a subungual hematoma is a nail bed laceration (cut).

If left untreated, a simple subungual hematoma typically grows out with the lengthening nail plate and resolves on its own. Of note, sometimes subungual hematomas can result in your nail falling off (i.e., onycholysis).

Subungual hematoma drainage is not necessary if the hematoma is not painful. If blood is spontaneously draining from the hematoma, drainage is also unlikely to be of additional benefit. In the presence of acrylic nails, electrocautery is contraindicated until the acrylic nail is removed.

Shoes that are too tight or narrow can put pressure on the toenail, breaking blood vessels and leading to a pool of blood under the nail. Running or hiking down steep hills or stopping and starting suddenly, such as while playing soccer or basketball, can also cause a type of subungual hematoma.

In most cases, a small subungual hematoma will go away on its own in about two weeks without special care. A very large or painful hematoma can be relieved at a doctor’s office by draining the blood or removing the damaged nail.

Subungual hematoma drainage is not necessary if the hematoma is not painful. If blood is spontaneously draining from the hematoma, drainage is also unlikely to be of additional benefit. In the presence of acrylic nails, electrocautery is contraindicated until the acrylic nail is removed.

In general, five stages of hematoma evolution are recognized: hyperacute (<1day) intracellular oxyhemoglobin. isointense on T1 acute (1 to 3 days) intracellular deoxyhemoglobin. T2 signal intensity drops (T2 shortening) T1 remains intermediate-to-low early subacute (3 to 7 days) intracellular methemoglobin.

hematoma (he-ma-TOE-ma): a mass of blood. A subungual hematoma is a collection of blood that forms under a fingernail or a toenail. Damage occurs to the nail and the skin beneath the nail, and the lacerated skin begins bleeding.

Surgical Drainage. For some patients, surgical drainage is the best treatment for hematoma. If the patient has subdural hematoma due to which there is headache and weakness, urgent drainage is done by a neurosurgeon.

It can take up to 9 months for a minor subungual hematoma to heal under a toenail. A minor subungual hematoma usually heals over time without treatment. The trapped blood will eventually be reabsorbed, and the dark mark will disappear. This can take 2-3 months for a fingernail, and up to 9 months for a toenail.

The evacuation of subungual hematoma is a procedure used to treat bleeding underneath the nail. The procedure, also known as drainage or trephination, can remove the blood and other fluid that becomes retained under the nail due to the said condition.
