2025年1月2日 · 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.

2024年11月1日 · Metacarpal V – little finger. Each metacarpal consists of a base, shaft and a head. The medial and lateral surfaces of the metacarpals are concave, allowing attachment of the interossei muscles. The metacarpal bones are common sites of injury. Two common fracture patterns include: Boxer’s fracture – A fracture of the 5th metacarpal neck.

The metacarpal bones (Latin: ossa metacarpi) are also known as the metacarpals. They are five bones that form the middle part of the skeleton of the hand . These bones lie between the proximally located carpal bones and distally positioned phalanges .

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 metacarpal bones are homologous to the metatarsal bones in the foot.

The Fifth Metacarpal Bone (os metacarpale V; metacarpal bone of the little finger) presents on its base one facet on its superior surface, which is concavo-convexand articulates with the hamate, and one on its radial side, which articulates with the fourth metacarpal.

2023年11月3日 · Metacarpal bones (Ossa metacarpi) The metacarpus is a group of five bones of the hand between the phalanges and the carpus. Even though the metacarpal bones are small, they are classified as long bones since they have structural characteristics of long bones; each metacarpal bone consists of a shaft, distal head and a wide proximal base.

2023年8月4日 · The metacarpals form the osseous base of the complex lever system of flexor and extensor tendons of the hand. Understandably, fractures of the metacarpals disrupt this mechanism causing significant disability for the active or working patient and can come about from several different mechanisms.[1]

Metacarpal V fractures, especially metacarpal neck fractures, are known to the forensic society as a ‘boxer’s fracture’ and are described as being mostly caused by punching an immovable or firm object with force with a closed fist.

2025年1月28日 · Metacarpal bones are a group of five long bones in the hand, located between the wrist (carpal bones) and the fingers (phalanges).[6] These bones form the palm and contribute to the overall structure and movement of the hand. Each metacarpal is named and numbered from the thumb (first metacarpal) to the little finger (fifth metacarpal).

The metacarpal bones are typically five long bones at the distal end of the thoracic limb. They are sometimes called thoracic metapodium. They are numerated in a mediolateral sequence from McI to McV. The metacarpal bones have all the same segments:
