is one of the most important topics for those who are interested in learning the finest details about members of human body, and still remember that when you know what your body consists of ?then you will be able to understand and deal with it correctly. in the beginning to understand what is metacarpophalangeal joint? we should identify the meaning of the joints ?
what are joints?
Joint simply is a meeting place between bone and other bone, or between bone and cartilage or between two cartilages. There are different types of joints in certain areas of the skeleton, which also different in terms of the degree of usability of the movement.
There are many types of joints like
They are classified as follows:
This type of joint is fixed and can’t move such interdependence different skull bones together. With age fibrous strings disappear and be replaced by bone ligaments so that bones become united with each other,and that unlike the newborn child who be relatively mobile and incomplete configuration which adds a degree of flexibility.
2_Limited movement joints:
Exist between the superficial chondrocytes Layer, their flexibility allow the creation of simple movement as in the spine, These joints are found generally two types:
Symphysis: Exist between the spine and in the symphysis pubis and the deficit and iliac.
Syndesmoses: Like the fibrous joint existing between the lower end of the tibia and fibula.
3_Synovial joints(extensive movement):
This is kind of joints Exist in different parts of the body and it’s conciderd the most important and the most common joints in the body and stop their movement to the installation of the joint ligaments and the shape and breadth of the articular surfaces. Such as in (shoulder, wrist, elbow, hip, knee, ankle, and between the head and the first part of the spine).
Now it will be easy to recognize on the meaning of the metacarpophalangeal joint:
metacarpophalangeal joint Simply defined as the joints of a finger when the fist is closed.
And also any spheroid joints between the heads of the metacarpal bones* and the bases of the proximal phalanges.
*Metacarpal bone: any bone in hand exists between the wrist and fingers.
(MCP) joint or Metacarpophalangeal joint are the joints where the bones of the hands connect to the long middle bones of the fingers. The metacarpophalangeal joint also is one of five joints in each hand that connect the metacarpal bones in the palm to the phalangeal bones* in your five fingers.
phalangeal bones: are the bones that make up the fingers and toes. They are fourteen bones, three in every finger and toe, except for the thumbs and big toes which have only two phalangeal bones.
The metacarpophalangeal joint is the connecting between the concave bases of the first phalanx distally and the convex metacarpal head proximally. These joints are *condyloid with the movements of extension, flexion and abduction.
*Condyloid joint: is a type of synovial joint in which two distinct convex surfaces articulate with two concave surfaces his shape is condyloid joint permits movement in two planes, that’s allow to flexion, extension, abduction, and adduction are possible together with a small amount of rotation..
These movements can be appear by examining the wrist joint, . The movements of The metacarpophalangeal joint are good examples.
As we said before there are exception in The metacarpophalangeal joint that forms it’s” The Thumb”
With its movement limited mostly to extension and flexion.
The metacarpophalangeal joint of the thumb is considered to be a hinge, joint.
metacarpophalangeal joint is The large joints in the hand at the base of each finger
They act as complex hinge joints and are important for both power grip and pinch activities.
And now it’s the time to know the problems that could face M.P joint:
What is metacarpophalangeal joint pain (Arthritis)?
the Skeletal in humans consist of several bones and joints, The role of these joints is link the bones, There is a thin layer of cartilage on every joint, which protects and prevents the bones from wearing or tearing against each other. Metacarpophalangeal joint is the knuckle joints in the fingers that connect between the long bones in the hand and the smaller bones in the fingers.
These joints play important role in performing particular activities require holding things and gripping.
There are a lot of types of arthritis. However, the most common type of arthritis that affects the metacarpophalangeal joint is “Rheumatoid arthritis”.
“Rheumatoid arthritis” of MCP joints:
The patients with rheumatoid arthritis of metacarpophalangeal joint most of them suffering from swelling and longstanding pain, and deformity in multiple joints of both the lower and upper extremities.
The most known symptom of this condition is difficulty in using the hand when you doing everyday activities, like gripping something or holding anything, and also people who suffer from arthritis of the metacarpophalangeal joint may suffering from leaning the fingers to the little finger side of their hands.
And also may accompany this pain swelling and stiffness severity varies from one case to another, and Joints appear red and hot to the touch, With time the fingers tend to become weak, and restrict the movements of the wrist and fingers. and symptoms of arthritis of MCP in the fingers maybe even get distorted. As a result, the person may lose the ability to grab or hold things.
There are many reasons causing injury this pain of the arthritis of metacarpophalangeal joint, such as an injury to the joints or the hand, then gout and psoriasis and many other diseases.
All these cause pain when they destroy the muscles and structures that move the joint or when they the surface of the joint very weak.
Arthritis of MCP is diagnosed with the help of medical history and physical examination and laboratory tests such as blood tests, x-rays, etc.
Notable very important: Before anything you should consult your treating doctor for your condition, the degree of inflammation and the appropriate treatment, which will come with the desired result.
But we can say the treatment methods in general:
Various treatment alternatives are available depend on the degree of patient’s complaints and the joint destruction.
In the beginning, drugs are given anti-inflammatory drugs and pain relief and to provide temporary relief from the pain.
There are also topical creams or ointments to relieve the pain. If these drugs fail in bringing about an improvement in the situation.
Cortisone injections may be used to reduce the pain of arthritis. In some cases, it is advised also wear “Splints” provide adequate protection and support for the protection of the affected joints inflamed.
And also we must not forget physical therapy is very useful for the treatment of arthritis of the hand,Where the patient is doing some exercises to strengthen the hand muscles and improve flexibility,Thus the movement of the fingers is restored arthritis with time and Continuously exercises.
But if there was damage in the joints and deformation has occurred due to arthritis Here are “surgically intervene”, now There are various surgical techniques used for this purpose where it is surgically removing the damaged portion of the inflamed joint.
