Nail injuries are common and can occur when a heavy object crushes or hits the fingers or toes, or when a person is cut by a sharp object. Treatment depends on the type and seriousness of the injury, and some injuries can be treated at home, while others require medical attention. The healing time for nail injuries varies depending on the severity of the injury and whether there are any other associated injuries, such as broken bones. In general, a fingernail can take about 4 to 6 months to grow back, while a toenail can take up to 12 to 18 months.

Healing time depends on the type and seriousness of the injury
The healing time for nail injuries varies depending on the type and severity of the injury. Minor nail bed injuries, such as subungual hematomas, often heal on their own without any additional medical issues. However, more severe hematomas may require a doctor to drain the pooled blood, a procedure known as trephination. In some cases, the doctor may need to remove the nail entirely to repair the nail bed and matrix.
If a bone is broken, a doctor will repair any other injuries and then splint the broken finger or toe to keep the bone in place. If the bone is out of alignment, a specialist may need to insert a wire into the finger to stabilise the bone. Antibiotics may be prescribed to prevent infection, especially if there is a laceration. Stitches in the skin or nail will need to be removed within 7 to 14 days, while stitches in the nail bed will dissolve on their own.
For a lost nail, the nail bed will take around 7 to 10 days to heal. A new fingernail will take approximately 4 to 6 months to grow back, while a toenail can take up to 12 to 18 months. During this time, it is important to keep the area dry and protected to prevent infection. Any sharp edges should be filed down, and the nail should be covered with tape or a bandage until it has grown out sufficiently.
The healing time and treatment plan for a nail injury depend on the specific type and severity of the injury. It is always best to seek medical advice to ensure proper care and promote optimal healing.

Healing a detached nail involves removing the nail, keeping the area dry, and waiting for a new nail to grow
Healing a detached nail can be a lengthy process. It involves removing the nail, keeping the area dry, and waiting for a new nail to grow. Depending on the severity of the injury, it may take anywhere from a few days to several months for the nail to heal completely.
If you have completely lost your nail, it will typically take about 7 to 10 days for the nail bed to heal. During this time, it is important to keep the area clean and dry to prevent infection. Cover the nail bed with petroleum jelly and an adhesive bandage, replacing it whenever the bandage gets wet. This will help keep the area protected and promote healing.
Once the nail bed has healed, you will need to wait for a new nail to grow. For fingernails, this process can take anywhere from 4 to 6 months, while toenails typically take about 12 months to grow back. In the meantime, it is important to keep your nails trimmed short to prevent them from catching on objects and causing further damage.
If you are uncomfortable trimming the nail yourself or have certain medical conditions, such as diabetes or peripheral arterial disease, it is recommended to seek medical advice. Leaving a detached nail unattended can lead to infections, foot ulcers, and other serious complications.
Additionally, it is important to address the underlying cause of the nail separation. Onycholysis, for example, can be caused by injury, fungi, or other medical conditions. In some cases, antifungal medications or discontinuing the use of certain nail products may be necessary to promote healing and prevent further issues.

Doctors may treat a severe subungual hematoma by draining the pooling blood
Nail injuries vary in severity, and the healing time depends on the type and seriousness of the injury. For instance, if you lose your nail, it will take about 7 to 10 days for the nail bed to heal, but a new fingernail will take about 4 to 6 months to grow back. Toenails can take about a year to grow back.
In the case of a severe subungual hematoma, a collection of blood forms in the space between the nail bed and the fingernail or toenail due to direct trauma. This can cause intense pain and may require medical attention. One treatment option is trephination, a quick outpatient procedure where a small hole is made in the nail to drain the pooled blood and relieve the pressure and pain. This procedure is typically performed by a healthcare provider and can be done quickly and relatively painlessly in a doctor's office or urgent care centre.
It is important to note that not all subungual hematomas require drainage. Smaller hematomas may resolve without intervention. However, if the injury is causing severe pain, drainage may be recommended to alleviate discomfort and prevent further complications. The procedure is generally safe, but there is a small risk of infection, minor nail bed injury, and re-accumulation of the hematoma.
To prepare for the procedure, the area around the nail is cleaned with antiseptic solutions such as alcohol, iodine, chlorhexidine, or povidone. The doctor may then use a needle, an electrocautery device, or a special tool to create a small hole in the nail, allowing the blood to drain out. After the procedure, it is normal to experience drainage from the nail for up to 36 hours, and the nail may remain discoloured for several weeks.
It is recommended to seek medical care after trephination if there are any signs of infection, such as red or discoloured skin around the nail, or purulent drainage (thick, milky fluid). It is important not to attempt to drain a subungual hematoma at home, as it may lead to complications and delayed healing.

Doctors may remove the nail if the finger or toe is fractured
Nail injuries can occur due to various reasons, such as a blow to the nail, closing the finger in a door or drawer, or a cut from a sharp object. These injuries can result in conditions like subungual hematoma, which is characterised by blood under the nail, causing pain and throbbing. In some cases, the nail can split, crack, or lift away from the nail bed. Repeated trauma to toenails from ill-fitting shoes can also lead to deformities.
When it comes to treating nail injuries, doctors will first examine the extent of the damage and decide on the appropriate course of action. If the injury is minor, it can often be treated at home by stopping any bleeding, removing jewellery, and applying a bandage if needed. However, more serious injuries may require a visit to an urgent care centre or emergency room.
In cases where the finger or toe is fractured, doctors may remove the nail to access and treat the fracture effectively. This allows them to repair the nail bed and provide protection and support while the new nail grows. The removal of the nail is also considered if the nail bed matrix is damaged. Doctors may use stitches to repair lacerations to the nail bed and reattach the nail if possible. Antibiotics may be prescribed to prevent infection, and X-rays may be ordered to check for bone fractures.
The healing time for nail injuries can vary depending on the severity of the injury. For a fractured finger or toe, it typically takes about four weeks for the bone to heal. However, the complete regrowth of a fingernail can take about two months, while a toenail may take up to four months or even longer. During the healing process, it is important to keep the injured area clean and dry, follow wound care instructions, and take any prescribed medications, such as antibiotics or pain relievers.

Home treatment can help relieve pain, promote healing, and prevent infection
The healing time for nail injuries varies depending on the severity of the injury. If you lose your nail, it will take around 7 to 10 days for the nail bed to heal. A new fingernail will take about 4 to 6 months to grow back, while a toenail can take up to 12 months. During this time, the new nail may have grooves or ridges and be misshapen, which could be permanent.
To reduce throbbing and pain, apply ice wrapped in a cloth for 20 minutes every 2 hours on the first day, and then 3 to 4 times a day after that. Keep the injured hand or foot elevated above the level of your heart. Over-the-counter medications such as ibuprofen or naproxen can help reduce pain and swelling, while acetaminophen can be used for pain relief. Always follow the directions on the medication packaging and consult a medical professional before taking any medication if you have any pre-existing health conditions.
It is important to monitor the injury site for any signs of infection, especially if you have diabetes, poor circulation, AIDS, are undergoing chemotherapy, or have another condition that affects healing or increases the risk of infection. If you notice any redness, drainage, or increased pain at the site after 2 to 7 days, seek medical attention. Most nail injuries are best treated at a hospital's emergency department, where you can receive specialized care and prevent further complications.
