Ligaments of the Fingers of the Hand Collateral

The collateral ligaments of the fingers (lat. ligamenti collateralia digitorum manus) are a group of ligaments that connect the fingers to the bones of the wrist. These ligaments are located on the sides of the fingers and help maintain their shape and stability.

The collateral ligaments of the fingers consist of several small ligaments that are located on the lateral surfaces of each finger. They connect the finger to the scaphoid bone (os scaphoideum), lunate bone (os lunatum) and triquetrum bone (os triquetrum).

These ligaments play an important role in maintaining finger stability and mobility. They also help keep your fingers in the correct position when performing various movements and actions.

In addition, the collateral ligaments of the fingers are involved in the formation of the shape and structure of the fingers. For example, they help shape the curve of the nail and keep it in the correct position.

With injuries or illnesses involving the hands, the ligaments in the fingers may be damaged or weakened. This can lead to decreased finger mobility, pain, and other symptoms. In such cases, surgery or other treatments may be required to restore normal finger function.

Introduction

Finger ligaments are a group of connective tissue structures that are located between the fingers and the hand. They play an important role in maintaining the stability and mobility of the hand, as well as in controlling the motor functions of the fingers. In this article we will look at the collateral ligament of the finger (Latin name l. collateralis dgtorum manus), or simply collateral ligament.

Collateral ligament of the finger

This ligament is located on the sides of the finger, opposite the big toe. It consists of two fascial sheets connected to each other by bundles of collagen fibers. Each bundle begins on the lateral side of the finger and runs in an arc forward to the collateral ligament of the thumb. Collagen bundles within the digit collateral connection are connected to the dorsal structure of the digits, also known as the lateral digit structure. The length of the bundles of collateral ligaments in the hand is several millimeters. The end of the fascicle is near the fibrous-osseous joint, called the third angle.

What is the collateral carpal ligament?

In short, it is a ligament that connects two or more fingers along the palmar side of the hand and plays a key role in the stability and function of the hand.

For more information about the collateral ligaments of the hand and their functions, read the next subsection.

Functions of the collateral palmar ligaments

One of the most important functions of the palmar collateral ligaments is to stabilize the thumb joint: the phalanx attaches to the other four fingers through the interphalangeal joints. To the metacarpal bone - using the wrist. Collateral ligaments are stretched between these three bony structures of the phalanx of the thumb and wrist, through which movement and stabilization are carried out.

Stabilizing the wrist at the thumb joint is called flexion. This process occurs within the connective tissues of the extensor head of the wrist joint and two collateral ligamentous structures. Fingers have their own ligament
