The pale joints are the most used connections. Its function is necessary to capture and manipulate objects and perform complex tasks.Continue reading for more information about the connections of your fingers, including its structure associated with the conditions and treatment of these conditions.
The hand contains 14 fallangetic bones that make up the fingers. The term Falanx is the only one, referring to a fairy bone.Each finger contains three phalanges (proximal, medium and distal), and the thumb has two phalanges.
Finger numbers are usually called thumb, index finger, long finger (or medium), ring finger and small finger (or little meñique) , although other names are used to describe them.While the thumb is not called finger, it is still considered to be connections of the fingers.
Dice of the Fingers however, they are called, they are from the rest of their body. The nearest bone to his palm is the proximal Falanx.Maybe next to his proximal be his medium fallanx. The last of these bones are the smallest and most distant from your hand and are called Phalange distal.
Three connections of your fingers:
- minarrepornia (MCP): Also called Bones, this is where there are dice from the YEMASEN each finger and The thumb, the metachary bone is connected to the proximal phalanx.
- Proximal interfirm joint (PIP): This is a connection in the middle of a finger that connects the proximal and medium phalanges.
- Distal interched articulation (immersion): This is an articulation, closest to the tip consultant, the average connection and the distal phalanges. The thumb does not have failures or distal phalanx.Failure
These meetings have surface cartilage , which connects your bones. Bone surfaces in which the bones that form together are connected to the cartilage layer are connected.The purchase helps them move carefully each other. The interior of the pale joints is a fibrous capsule, aligned with the X synovium , a thin membrane that highlights the liquid to lubricate the compounds.
The thumb offers a couple of unique features that your other numbers do not do it. First, the tip of the thumb can concern all the fingers of the same hand. Also the thumb movement range is the reason that you can understand and keep the objects by refusing
Congenital conditions and anomalies GeneticsThe fingers generally occur when the child develops in the uterus. For example, the fetus may have lower or less additional fingers or fewer joints on the finger.Examples of conditions that cause defects from the joints of the fingers and finger, include the polyadactic hand, the syntax and the clean hand.
polydacticks means having additional fingers or fingers.The finger or an additional sock can be a small tip or an additional cloth, or it can be a digit that functions with nerve end, joint and bone.This can be attached an additional finger to additional joints or an additional bone.
sindactyly are straps or fingers of fingers or fingers. With this condition, the numbers are not divided into hand or leg. This condition is simple or difficult. When simple, only the skin connects the numbers.
With the complex syntax, the bones can be merged, along with the blood vessels, the nerves and other soft tissues. Both types of sites affect the movement and the ability to bend the compounds of the fingers.
Hidden means that in the fingers or parts of the fingers there are differences in the fingers. Often, the fingers in the center of the hand are missing the creation of a V-shaped bleeding (called slit).With a slit hand, the movement of the joints of the fingers can sometimes be limited.
your fingers are vital to complete daily tasks, and are your most used tips. They allow you to achieve most events that daily daily. When any part of your hand does not work correctly, daily activities, such as bath, cooking, compliance with your work, and child care It makes it harder.
A hand consists of approximately 27 bones, and 14 of them are on your fingers. Your fingers move freely, with four fingers that allow you to bend and stretch in one direction. Each finger can move independently of others.
The movements of the normal fingers include:
- folding and extension : move the base of the fingers towards and get away from the palm and move Two parts of the fingers to and away from the bases of the fingers
- addingIPochismo : Move your fingers to and move from the middle finger
The thumb can perform different movements. On the carpometer card board,The compound of the thumb can perform the following movements:
- Move the connection under the thumb to the
- move the connection under the thumb of your hand
- moving the thumb in the palm to other fingers
Move the articulation under the big finger to the shoulders,as well as the front
in the MCP connection at the base of the thumb,The following movements can occur:
- Move the connection on the base of the big fingers to the heel of the hand (rounded part at the bottom of your palm) and away from the heels
- moves the base of the thumb to and away from the base of theThumb
The NIP connection of the thumb can be folded to the base of the thumb and move away from the base.
All these movements are possible by linked muscles and flexors. However, your fingers do not contain any muscles. The muscles that help with the movement of the finger are found in the palm and forearm.
His forearm consisting of the poplar and radius the bones extend from his joint of the elbow in his hand.The long tendons of your forearm muscles can be seen under the skin on the wrist and the back of the hands.
The thumb also has bending bending, as well as a long folded and a short curve. The thumb has other muscles that arise from the curves that help you move in opposition and exciting objects.
The muscles of the extension also help the movement of the fingers and a thumb. They are located on the back of the forearm and the back (back hand in hand). The main function of these muscles is straightening your fingers. / P>
Big thumb has two extensions on the forearm. Your index and rotary finger have an additional extension that can be used to indicate.
finger and thumb movement also arise from the muscles of the depression (thumb), the hypothenic muscles (small finger), the dorsal muscles and the inter-server muscles (between metacquetres), as well As in light muscles. . These dorsal expansions are special connection accessories where the elongated tendons are inserted into counterfeits.
Another interesting feature of the joints of the fingers and arms is the ability to perceive all kinds of objects. The hands can be perceived by two precise control or grip controls.Help can help raise large or heavy objects, while grip accuracy is useful for the retention of smaller and smaller objects.
With the feed handle, holds the object in the palm of your hand, and the long bending tendons help attract the fingers and thumb so that the object can be firmly understood.Thanks to the ability to bend and thumbs are the ability to position yourself in front of your fingers, power is possible, even with large and heavier objects.
The precision handle helps grab small or delicate items, such as when writing a pencil or wear tweezers. This clutch generally includes the use of thumb and index fingers.
The relevant conditions
Your fingers are important for the completion of daily tasks. They are one of the most commonly used extremities, and they are also the most delicate.Problems with pale joints can occur from different types of injuries. In addition, many different conditions, including arthritis, can affect the compounds of the fingers.
You must contact your health care provider, if you experience intense pain in front of your fingers, numbness and tingling under your fingers or all compounds, bending problems or straightening fingers, if the finger seems inclined,Broken or curved, or if you have pain and fever, what lasts more than a week. Intense pain in the joints or the damage visible to the finger of the joint must be drawn at the same time. X-rays can help determine if you have a fracture or other injury.
You may experience a sudden injuries Ósludes to your fingers of direct, autumn or torsional impact, flexion or joint jamaming is abnormal. The pain you are experiencing strong and can be bruising or swelling.
Older people are susceptible to injuries and fractures, because people lose bone strength and muscle mass with age.Older people also have an increased risk of injury due to changes in their vision or balance.
Easter packets Silent Injuries of injuries
Injuries In the elbow the packages (UCL) are common. UCL is a strong tissue lane that connects to the central thumb (MCP). Any difficult force inside the thumb can lead to UCL lesions. It can also be weakened over time due to degenerative aging.
Flight and Displace of the fingers
before fingers and dislocations They are fairly common injuries. The tensions of the fingers occur when the connections that connect with the bones and the joints of the fingers extend too far. The distance can occur when the connection of the finger extends from its alignment. .
Finger of the trigger ). ./ Li>
rigidity and inability to bend your finger or thumb worse in the morning .Rigidity decreases with movement and use of affected finger connections.
Warning of arthritis
osteoarthritis (OA), type of wearing arthritis, can affect your fingers.This can affect the basilar compound that connects the thumb and wrist heads, the tips of the fingers (diploma compounds) and the middle knuckles (PIP connections) of your fingers.
with OA, the cartilage between the finger connections is below, and without this pillow, the dice of the fingers will begin to lose each other . This rubbing will lead to joint inflammation, pain and rigidity.
ROOMATOID ARTRITIS (RA ) – Chronic inflammation autoimmune disease caused by an excessive immune system, which mainly attacks the joints. The connections, the most common RA, are small joints of the hands and fingers. If you do not get rid, RA can lead to deformations of hands and fingers and make it difficult to use your hands.
Another type of inflammatory arthritis, which can affect the compounds for the fingers, is psoriatic arthritis (PSA). PSA may cause dactylitis where the palastic joints swell so swollen that the fingers resemble the sausages.
The treatment for the conditions that affect the compounds of the fingers is based on the cause and the symptoms.
When it damages your finger or more of a finger, rest and Ice, as a rule, the first procedures, including fractures. Your healthcare provider can also recommend non-steroidal anti-inflammatory drugs (NSAID) to control injury pain.
For Aninjury, which does not require surgery, your health care provider can offer:
- splint or onlycing: stickers includes finger union Affected to another finger to limit the movement; filling can help in the same way.
- If your hand is also injured, your health care provider may recommend a support or tires to limit the movement and protect the affected connections.
After the injury begins to cure, your health care provider can prescribe physical therapy to help you restore strength and use of participation .In some cases, it is possible that you need surgical interference, even for the treatment of torn fractures and tendons. The operation is carried out to repair the function of damage and restoration in the connections of the fingers and / or affected.
Targets of partial or minimum UCL are treated, covering A thumb in distribution up to four weeks, and then removable tires that should be used Hastamientras moves and stability will not be restored. The full UCL break will require an UCL Reattach operation.
If the UCL injury is not processed correctly, the MCP connection will become arthritis after a long period of instability. After it becomes arthritis, you must repair damage.
Stretching the fingers and the dislocation
The stretching fingers and dislocations need adequate diagnoses and immediate attention.If it is not treated, the pallets and bones will not be treated correctly, which leads to the loss of mobility or constant damage to the joints.
The soft stretching to the modular of the fingers and the dislocations are generally processed by leisure, ice, compression, height (FIG) and Drafting .If there is no interruption of the bones, the bone can be returned on the site without surgery using a technique called decrease. , But if there is a violation or participating ligaments, surgery is required to stabilize the affected finger, so that it can be treated properly.
after the healing of the affected joint. Physiotherapy can help restore mobility, the range of movement and strength.
Soft activation cases can be controlled by reviewing the injured finger or thumb and limiting o Avoiding activity causing symptoms. Schrabin can prevent the affected connection from moving.If the symptoms continue, your health care provider can offer combination of AIDE pain or steroid injections to control pain and edema.
If non-governmental procedures do not help, your health care provider may recommend an operation. Surgery includes the expansion of spaces around the tendons of the affected fingers or thumb. This will restore the capacity of the compounds to bend and straighten without rigidity and pain.
Wear and tears Arthritis
Treatment for the or manual and pallet boards can help relieve pain and Improve the use of affected joints.This may include:
- pain relief : These include NSAIDs (such as ibuprofen) and analgesics (such as acetaminophen), to make it more Easy to reject, it can also get relief from relief pain,Using the medicinal creams that rubbed into the blunt joints.
- Immobilization tools : Support, tire, sleeve or record can be used to stabilize your hands and / or fingers.
- Manual therapy : Manual exercises and simple ways to make everyday tasks help with pain and continue turning from affected connections.
- Cortisone / Strong>: Injection to the affected joint can help solve your pain for several weeks or months.Steroids in small joints of fingers and thumbs: These are general procedures to improve function and reduce pain. However, these shots can be done only a few times, because they are risks of infection and relaxing a ligament.
- Auxiliary devices : devices such as special handles, kitchen utensils and other tools that will help relieve pain and facilitate the use of pallets
- ice or heat,To control the symptoms : the ice can relieve pain and swelling, and thermal therapy (ie, heating pads or paraffin bath ) can reduce rigidity in connections of the fingers. / UL>
- NSAID to reduce swelling,Rigidity and pain
- corticosteroids to reduce inflammation and pain of relief
- creams to facilitate pain for pain relief and other discomforts
- Standard diseases Modifying anti-Rheumatic medications (DMARDS) to reduce the system (full body) Inflammation and symptoms
- Biological yards To slow down or stop harmful inflammation
When treatment does not work, and it indicates more difficult to use your hands and fingers, your health care provider You can recommend an operation. This can include a combination of joints , where the surgeon eliminates a damaged part of the joint, and the bones merge.Another option is a joint replacement operation , where the damaged joint is eliminated and replaced by the implant.
When conditions, like RA and PSA affect numbers From your hands, the treatment begins with the control of the source of these symptoms.
Treatment may include:
