Metacarpal ligaments

Metacarpal Ligaments are a group of ligaments that connect the metacarpal bones in the hand. They play a crucial role in the stability and flexibility of the hand, allowing for a wide range of movements.

Anatomy

The metacarpal ligaments are divided into three main types: the dorsal metacarpal ligaments, the palmar metacarpal ligaments, and the interosseous metacarpal ligaments.

Dorsal Metacarpal Ligaments

The dorsal metacarpal ligaments are located on the back of the hand. They connect the metacarpal bones to each other, providing stability and preventing excessive movement.

Palmar Metacarpal Ligaments

The palmar metacarpal ligaments are found on the palm side of the hand. They also connect the metacarpal bones to each other, but they are more flexible than the dorsal metacarpal ligaments, allowing for a greater range of movement.

Interosseous Metacarpal Ligaments

The interosseous metacarpal ligaments are located between the metacarpal bones. They provide additional stability and help to maintain the alignment of the bones.

Function

The metacarpal ligaments play a crucial role in the function of the hand. They provide stability, prevent excessive movement, and allow for a wide range of movements. They also play a role in the transmission of forces from the fingers to the wrist.

Clinical Significance

Injuries to the metacarpal ligaments can result in instability, pain, and reduced function of the hand. Treatment may involve physiotherapy, surgery, or the use of a splint or cast.
