In human anatomy, the metacarpal bones or metacarpus, also known as the "palm bones", are the appendicular bones that form the intermediate part of the hand between the phalanges and the carpal bones (wrist bones), which articulate with the forearm.

The metacarpals are a group of bones in the human hand, between the wrist and the finger bones [1]. These bones are classified as long bones, and together, they are called the metacarpus, forming the palm of the hand [2] There are five metacarpals in each hand, with each bone being associated with a specific finger [1]:

Jan 2, 2025 · Metacarpal Fractures are the most common hand injury and are divided into fractures of the head, neck, or shaft. Diagnosis is made by orthogonal radiographs the hand. Treatment is based on which metacarpal is involved, location of the fracture, and the rotation/angulation of the injury.

Nov 3, 2023 · The metacarpal bones articulate with the carpal bones with their proximal ends (bases), and with the proximal phalanges via their distal ends (heads). They are labeled with numbers 1-5 going in the radio-ulnar direction. This article will discuss the anatomy and function of the metacarpal bones.

Nov 1, 2024 · Metacarpals – a set of five bones, each one related to a digit. They are located in the area of the palm. Phalanges (distal) – the bones of the digits. The thumb has two phalanges, whilst the rest of the fingers have three.

Jan 28, 2025 · The metacarpal bones are five long bones forming the framework of the palm. They are numbered from the thumb (first metacarpal) to the little finger (fifth metacarpal). Each metacarpal consists of three main parts: the base, shaft, and head. [4]

Mar 9, 2022 · The metacarpal bones are five long bones of the hand between the carpal bones and the proximal phalanges of the hand that make up most of the palm. The metacarpal bones run from the carpus, forming the carpometacarpal joints, to the base of proximal phalanges, forming the metacarpophalangeal joints. The thumb metacarpal is shorter and thicker.

metacarpal, any of several tubular bones between the wrist (carpal) bones and each of the forelimb digits in land vertebrates, corresponding to the metatarsal bones of the foot. Originally numbering five, metacarpals in many mammals have undergone much change and reduction during evolution.

Mar 29, 2025 · Explore the anatomy and function of the metacarpals with Innerbody's interactive 3D model. The metacarpal bones are a group of five long bones found in the palm of each hand. These bones support the structures of the hand and provide flexibility to the hand so that it can bend and stretch.

The fifth metacarpal bone (metacarpal bone of the little finger or pinky finger) is the most medial and second-shortest of the metacarpal bones. Surfaces. It presents on its base one facet on its superior surface, which is concavo-convex and articulates with the hamate, and one on its radial side, which articulates with the fourth metacarpal.
