Understanding the Anatomy of the Fingertip

The fingertip is a remarkably complex structure with numerous specialized features. To fully grasp the impact of crushed finger injuries, it’s essential to understand the intricate anatomy of this body part.

Key Components of the Fingertip

• Nail plate: The visible part of the fingernail
• Nail bed: The pink tissue beneath the nail plate
• Germinal matrix: The part of the nail bed that produces the nail plate
• Lunula: The visible white, moon-shaped area of the germinal matrix
• Eponychium: The proximal nail fold, also known as the cuticle
• Hyponychium: A specialized structure under the nail plate at the distal end

The fingertip also plays a crucial role in temperature regulation. Special valves in the fingertips open to increase blood flow when the body is hot and close when it’s cold, explaining why fingertips can become particularly cold in chilly weather.

Types of Crushed Finger Injuries

Crushed finger injuries can occur in various ways and result in different types of damage. Understanding these injuries is crucial for proper treatment and recovery.

Common Causes of Crushed Finger Injuries

• Hammer strikes
• Car door accidents
• Heavy object impacts
• Machinery-related incidents

Can crushed finger injuries lead to complications? Yes, crushed finger injuries can result in several complications, including:

• Subungual hematoma: A collection of blood under the nail plate
• Tuft fractures: Fractures of the fingertip bone
• Nail plate separation: Detachment of the nail plate from the germinal matrix
• Swelling and pain: Persistent symptoms following the injury

Diagnosis and Immediate Treatment of Crushed Fingers

Proper diagnosis and immediate treatment are crucial for the best possible outcome in cases of crushed finger injuries.

Crushed Finger – Connecticut Orthopaedics

Richard A. Bernstein

The fingertip is a highly specialized structure, with many specialized features. It has a lot of nerves, as I am sure you are more aware of than you would like! The illustration below shows many of the important structures of the fingertip.

The fingernail itself, the thing that you cut with a fingernail clipper, is called the nail plate. Underneath the nail plate is the nail bed, the mostly pink tissue you can see under the nail. It has several regions. The proximal (this is a medical term that is good to understand, it means that part closer to the heart; the opposite direction is called distal) part of the nail plate is called the germinal matrix. This is the part of the nail bed that originates the nail plate.

When you look at your fingertip, part of the germinal matrix can be seen through the nail plate: it is the white moon-shaped area. The name for this is the lunula. That is, the lunula is the visible part of the germinal matrix. The majority of the germinal matrix is not visible, and it is located under the proximal nail fold, or eponychium. The cells of the dorsal roof in the eponychium are responsible for placing the shine on your nail plate.

The hyponychium is a specialized structure under the nail plate at the distal end. Its purpose is to help prevent dirt and bacteria from entering under the nail into the nail bed. It is backed by specialized capillaries (small arteries) and lymphatics that also help to prevent the invasion of bacteria or fungus under the nail plate.

The fingertip is also an organ of temperature regulation: if you are hot, special valves open up to allow increase blood flow to your fingertips. If you are cold, these valves shut off (this explains why your fingertips get so cold in cold weather!) The fingertip is a very specialized structure!

Fingertip Crush Injuries

There are many kinds of fingertip injuries, from crushed fingertips (hit with a hammer, smashed in the car door, and other things that are just too painful to think about!) to cuts all the way to various levels of amputation. This page will The nail bed can bleed, which creates a collection of blood (called a hematoma) under the nail plate. This is called a subungual hematoma. They can be very painful, and sometimes need to be drained. This usually dramatically decreases the pain of a fingertip injury. Fractures of the fingertip, usually of the type called a tuft fracture, usually heal well if given a chance to rest. A splint and rest is all that is needed.

If the nail’s germinal matrix is crushed or otherwise injured, the nail plate may separate from the germinal matrix. This is usually not a problem. What will happen is a new nail plate will form, and it will eventually push off the old nail plate. You don’t need to do anything, just protect the old nail plate from ripping off (it even sounds painful!) by covering it with a band aid. Trim off whatever you can trim easily, so there will be less to catch. Give it time. It usually takes about three months for the new nail to come in completely.

A crushed fingertip will always be swollen and painful. Keep your hand elevated and take both an anti-inflammatory (such as aspirin or Motrin, if you can take such medication) and Tylenol. These work in different ways and it is a case of 1 + 1 = 3. Ice will be very helpful for the first day or three. Be sure to take both an anti-inflammatory and Tylenol.

The fingertip will usually stay a little bit swollen permanently, but it should not interfere with function. It will take longer than you think is reasonable, about six to twelve months, for the swelling to go down as much as it will.

Keep your dressing dry. Moisture will promote a bacterial infection. Use a plastic bag when you shower. If you get it wet, you will need to change the dressing.

If there is a fracture, most but not all times, it will heal. Occasionally tissue known as fibrous tissue will bridge the gap, especially with breaks towards the very tip of the finger. Usually this is not a problem since the fibrous tissue should provide enough stability to the finger. Over years, sometimes this fibrous tissue will turn to bone.

A smashed finger develops from trauma to the finger. Your finger will swell and become bruised, and you may experience severe pain or loss of feeling, among other symptoms. It usually heals easily with some rest and icing to the area.

If you’ve ever caught your finger in a door or hit it with a hammer, you’ve probably experienced common symptoms of a smashed finger. Any trauma or injury to your finger can lead to:

• severe finger pain, especially aching and throbbing pain
• inflammation (pain, redness, and swelling)
• difficulty using the finger tip
• loss of sensation in the finger tip
• bruising and color change of the skin and fingernail
• stiffness in your finger

The fingernail on the smashed finger may also fall off within a week or two of the injury.

Read on to learn more about treating a smashed finger, and when you need to seek help.

The best way to get immediate relief from a smashed finger is to treat inflammation. Inflammation is the primary cause of pain, swelling, and redness.

Common tips for treating a smashed finger include:

Rest

Once you’ve hurt yourself, stop whatever you’re doing to prevent further injury. As painful as it may be, try to calmly assess the damage and whether you’ll need medical attention.

Ice

Very gently apply an ice pack or compress wrapped in a hand towel or cloth to the injured finger for 10-minute intervals with 20-minute breaks, several times daily.

Never expose the skin directly to ice, or for longer than 10 to 15 minutes at a time, to avoid the risk of frostbite or further inflammation.

To avoid putting weight on the injury, rest the finger on top of a covered ice compress or pack.

Elevate

Elevating the injured finger above the level of your heart slows the flood of blood to the site, limiting inflammation and pressure. This is extremely important and needs to be done continuously, not just intermittently.

Use over-the-counter (OTC) pain medications

OTC anti-inflammatory and pain medications like ibuprofen (Advil, Motrin), acetaminophen (Tylenol), and aspirin can help reduce inflammation and associated pain.

Clean and cover open wounds

If the nail or skin is broken, gently clean the area using soap and water, or an antibacterial rinse. Then, cover the wound with sterile gauze or bandages.

OTC antibiotic ointments or creams can also be applied to the wounds after cleaning sessions to help prevent infection.

Wounds should be cleaned and new dressings applied at least twice daily.

Make sure you can move your finger

Never wrap, splint, or brace an injured finger at home. It’s also important to try to keep gently moving the finger as much as possible without increasing your pain.

If you can’t move your finger, seek medical attention.

Use pain-relieving creams and herbal remedies

Pain-relieving medicated creams and herbal formulas can help reduce inflammation and pain. Arnica may help reduce inflammation and improve the healing time of bruises.

During the first 48 hours after the injury occurs, resting, icing, elevating, and taking OTC pain medications are the recommended course of treatment. Your pain should start to greatly improve after a day or two of basic care.

A painful bruise may develop at the injury site after the initial swelling goes down. Depending on the location of the injury and its severity, the bruise may cause throbbing, aching, or numbness.

Once the initial pain and swelling improve, you should increasingly try to stretch and move the injured finger. Avoid any movements or actions that cause your pain to increase significantly.

Gently massaging the injury site and the surrounding area can help improve recovery time by encouraging blood flow to the site. This can also help break up dead blood cells and tissues.

The recovery time for a smashed finger depends largely on the severity of the injury and location. Most smashed fingers start to feel much better within three to four days. More complicated or severe cases may take a few weeks or more to fully heal.

When a bruise develops under the fingernail, pressure can build up and cause pain.

If this pressure becomes severe, the fingernail may fall off. In most cases, though, your fingernail will remain in place, but you may notice discoloration around the site of the injury.

The bruise will remain visible for a few months until the affected portion of the nail grows out.

If you suspect that your nail may fall off, or the bruise is visible on 50 percent or more of the nail, call your doctor. Your doctor may be able to help prevent the nail from falling off by relieving pressure.

While your finger is healing, it’s a good idea to stay away from any activities that increase pain or involve a lot of finger strain. It may take a few weeks before it’s safe to return to activities like physical or contact sports.

You also shouldn’t attempt to remove an injured nail yourself, or wrap, splint, or brace the injured finger.

Speak with a doctor or nurse if your smashed finger causes extreme pain or involves more than just the fingertip. You should also seek medical help if:

• you can’t straighten your finger
• the finger is noticeable bent or crooked
• your finger feels numb immediately after the injury and before the use of ice
• your fingernail bed, finger joints, knuckle, palm, or wrist are also injured
• symptoms get worse after 24 to 48 hours of basic at-home care
• deep wounds are present
• you think the nail will fall off or a bruise takes up more than half of the nail
• bleeding or pus occurs at the site of the wound
• you hear an odd noise like breaking or cracking at the time of the injury
• the injury site stays extremely swollen for more than 48 hours

A smashed finger is a common injury that involves trauma to the finger. Though they can be very painful, most smashed fingers heal after a few days of at-home care.

Rest, ice, elevation, and the use of OTC pain and anti-inflammatory medications are generally the best way to get immediate and long-term relief from this injury.

Seek medical attention for injuries that involve the joints, have noticeable abnormalities or breaks, cause severe pain, or don’t respond to basic treatment.

1. What is a bone fracture?

Fracture is the medical term for a broken bone. Fractures are a fairly common problem, and according to statistics, the average person has two fractures in a lifetime. A bone fracture occurs when the physical force acting on the bone is stronger than the bone itself. Most often, fractures are caused by falls, blows, or other injuries.

The risk of fracture is largely related to the person’s age. Fractures often occur in childhood, although fractures in children are usually not as complex as those in adults. Bones become more fragile with age, and fractures usually occur after falls, even those that would not entail any negative consequences at a younger age.

2. Types of fractures

There are many different types of fractures , but the most common fractures are classified into displaced and non-displaced, open and closed fractures. The division of fractures into displaced and non-displaced fractures is based on how the bone breaks.

In a displaced fracture, the bone breaks into two or more pieces that are arranged so that their ends do not form a single line. If the bone was broken into many pieces, it is called comminuted fracture . During a non-displaced fracture, the bone breaks or may develop a crack, but still the bone remains straight and retains the ability to move.

Closed fracture is a fracture in which the bone breaks, but there is no open wound or puncture on the surface of the skin. During an open fracture, the bone can pierce the skin. Sometimes with an open fracture, the bone may break the skin, but then return to its original position and not be visible on superficial examination. An additional danger of an open fracture is the risk of infection of the wound and bone.

There are other types of fractures:

• Incomplete fracture where the bone bends but does not break. This type of fracture is most common in children.
• Transverse fracture – fracture at a right angle to the axis of the bone;
• Oblique fracture – fracture along a curved or oblique line;
• Fracture with many fragments and bone fragments;
• Pathological fracture – caused by a disease that weakens the bones. Cancer or, more commonly, osteoporosis can lead to pathological fractures. Fractures of the hip, wrist, and spine are most common due to osteoporosis.
• Compression fracture that occurs from strong pressure.

Classify fractures and depending on which bone was broken. The most common are leg fracture, hip fracture, arm fracture, spinal fracture, hip fracture, finger fracture, ankle fracture, clavicle fracture, rib fracture, jaw fracture.

3. Signs of a broken bone

Signs and symptoms of a broken bone may include:

• Swelling and bruising;
• Hand or leg deformity;
• Pain in the affected area, which is aggravated by motion or pressure;
• Loss of functioning of the damaged area;
• In an open fracture, a bone protruding from the skin.

The severity of a fracture depends on the location of the fracture and how severely the bone and soft tissues adjacent to it have been damaged. Serious fractures without timely treatment are dangerous for their complications. This may be damage to the blood vessels or nerves, infection of the bone (osteomyelitis) or surrounding tissues.

Recovery time after a fracture depends on the age and health of the patient, as well as the type of fracture. Small fractures in children heal within a few weeks. A serious fracture in an elderly person will require several months of treatment.

MRI of the hand: what kind of examination, when is it prescribed

All types of hand damage can be divided into several groups.

Let’s start with MRI diagnostics of traumatic injuries of the hand and wrist joint.

Clinical examination of patients with injuries of the wrist joint and hand, as a rule, is determined by pain on palpation, an increase in the volume of the surrounding soft tissues, and objectively and radiographically there are no changes. The most common bruises are the metaepiphysis of the radius and ulna, as well as the lunate and navicular bones. Bruises (contusion lesions) of the hand are determined only by MRI examination, it is especially clearly seen in programs with signal suppression from fat. Morphologically, a bone contusion is manifested by a violation of the integrity of the trabeculae of the bone tissue with hemorrhage and swelling of the bone marrow. However, despite damage to the bone tissue trabeculae, X-ray studies, including CT, do not allow detecting pathological changes.

The patient presented with pain and limitation of movement after falling on an outstretched hand 4 months ago.

Fracture of the scaphoid with signs of aseptic necrosis of the proximal pole and associated osteoarthritis. A navicular fracture usually occurs due to a fall onto an outstretched hand, which leads to hyperextension of the wrist joint.

Avascular (aseptic) necrosis often accompanies fractures of the proximal part of the scaphoid and lunate fractures, as well as inadequately reduced and immobilized fractures of these bones. The main reason is the violation of the trophism of the bone area when the supply arteries are damaged.

MRI is the method of choice in the diagnosis and staging of osteonecrosis of the bones of the hand.

This term is used to refer to fractures that were not initially detected by X-ray, but only detected by MRI. Only 5-10 days after injury, a fracture line appears on delayed radiographs. After 1.5-2 months. After injury, X-ray and SCT in patients with hidden fractures allow visualizing minor cloud-like osteosclerotic changes along the fracture line, as a manifestation of the reparative process.

Radiological diagnosis of damage to the ligamentous apparatus of the wrist joint and hand presents the greatest difficulties due to the complexity of the anatomy and the small size of this area. The possibilities of radiography and CT in the diagnosis of ligament injuries are limited. They are judged by the presence of indirect signs. Due to the relatively small size of the ligaments, ultrasound is difficult. The method of choice in the study of the ligamentous apparatus is MRI.

Clinical: Acute pain. There is no history of trauma or overuse. An increase in diameter and an increase in the MR signal in the projection of the extensor tendon.

MRI shows fusiform enlargement of the nerve, which is caused by thickening of the nerve bundles and fatty and fibrous proliferation. MRI characteristics of fibrolipomatous hamartoma are pathognomonic, eliminating the need for a biopsy for diagnosis.

Cystic formation in the projection of the dorsal intercarpal and radiocarpal ligaments; minor synovitis.

Tendon injury syndrome includes partial and complete tendon ruptures, manifestations of tenosynovitis and post-traumatic tendinosis. The main share is tenosynovitis that occurs in isolation or against the background of damage to bones and ligaments. Morphologically, tenosynovitis is characterized by the accumulation of synovial fluid under the tendon sheaths. X-ray diagnostics in the diagnosis of tenosynovitis is not informative. Ultrasound and MRI are the most informative in the diagnosis of tenosynovitis.

Tenosynovitis of the tendons of the deep flexor of the fingers of the hand and the long flexor of the thumb.

Clinically: Swelling of the left hand, persisting for a long time, at the moment the patient began to complain of a violation of the sensitivity of the lateral three fingers.

The encapsulated mass is attached to the superficial and deep flexor tendons of the index finger. Tendon lipoma (histologically proven).

Most injuries of the wrist and hand are accompanied by symptoms of concomitant exudative synovitis; its severity depends on the severity of the injury. An MRI shows a joint effusion. In addition, bone marrow edema is sometimes determined in the subchondral sections of the epiphyses of the bones, edema of the periarticular soft tissues.
