Ligaments of the bases of the metacarpal bones (lat. L. Basium Ossium Metacarpalium Dorsalia) are a group of ligaments that connect the bases of the metacarpal bones to the bones of the wrist. These ligaments provide stability and mobility to the wrist and metacarpus joints and protect the bones and joints from injury and damage.
The metacarpal base ligaments are located on the back of the wrist and provide the connection between the metacarpal bones and the carpal bones, such as the radius and ulna. These ligaments are made up of tough connective tissue that connects bones and provides them with stability.
There are several ligaments of the bases of the metacarpal bones. The most important are:
– Ligament of the base of the fifth metacarpal bone (lat. Tendo Metacarpalis Primus) - connects the metacarpal bone to the metacarpal bone.
– Ligament of the bases of the second and third metacarpal bones (lat. Ligamentum Metacarpale II et III) - connects the bases of the second and third metacarpal bones.
– Ligaments of the bases of the first and second metacarpal bones (lat. Ligamenta Metacarpea I et II) - connect the bases of the first and second metacarpal bones, providing their stability and protection.
In addition, the ligaments at the base of the metacarpal bones are also involved in the movements of the wrist and fingers, ensuring their flexibility and mobility. For example, when the wrist flexes, the ligaments at the base of the metacarpal bones stretch and allow the wrist to flex.
Diseases of the ligaments of the bases of the metacarpal bones can manifest themselves in the form of pain, swelling, impaired mobility and other symptoms. To diagnose and treat diseases of the ligaments of the bases of the metacarpal bones, you must consult an orthopedic doctor. Depending on the nature of the disease, various treatment methods may be prescribed, such as physical therapy, medication, surgery, etc.
In general, the ligaments at the base of the metacarpal bones play an important role in maintaining stability and mobility of the wrist and metacarpus joints.
Dorsal ligaments of the bases of the metacarpal bones [L. Basium (Ossium Metacarpalium) Dorsalia, BNA]
The dorsal metacarpal base ligaments are an important anatomical structure that provides stability and support to the metacarpal joints. They play a key role in the functioning of the hand and allow it to perform various movements with the necessary precision.
The dorsal ligaments of the bases of the metacarpal bones, consisting of slender fibers, are connected to each other and to the bones of the metacarpus, forming articular capsules and ligamentous apparatus. These structures maintain joint stability and prevent excessive mobility, which is especially important when performing small and precise movements of the hand.
The dorsal ligaments of the bases of the metacarpal bones can be classified according to their location and function. They include the following links:
-
Capsular ligaments: These ligaments form the joint capsule, surrounding the joint cavity and holding the articular surfaces together. They prevent excessive joint mobility and protect it from damage.
-
Collateral ligaments: These ligaments are located on the sides of the joint and prevent its lateral movement. They consist of the ulnar and radial collateral ligaments, which strengthen the joint and maintain its stability during flexion and extension.
-
Interosseous ligaments: These ligaments connect the metacarpal bones to each other. They provide stability and support to the metacarpus, allowing it to undergo a variety of movements such as flexion, extension, tilting and rotation.
-
Intermetacarpal ligaments: These ligaments connect the bases of the metacarpal bones to each other. They strengthen the joints of the metacarpus and prevent excessive mobility of the interosseous joints.
The dorsal ligaments of the bases of the metacarpal bones have important clinical significance. Damage to these ligaments can lead to joint instability, pain, and limited wrist movement. Some of the most common metacarpal ligament injuries include sprains, sprains, and tears.
In conclusion, the dorsal metacarpal base ligaments play an important role in providing stability and support to the metacarpal joints. Their proper functioning is necessary to perform a variety of hand movements. Understanding the anatomy and function of these ligaments is important for the diagnosis and treatment of injuries to the metacarpal region.
