Are Phalanges Short Bones? Decoding Hand Anatomy.

Are Phalanges Short Bones? Decoding Hand Anatomy

Your hand is one of the most delicate and intricate parts of your body. It’s a wonder of evolution, with each bone, ligament, and tendon working in seamless harmony to allow us to perform tasks from the mundane to the extraordinary. At the core of this complex system are the phalanges, the small bones that make up the fingers and toes. In this article, we explore the anatomy of the phalanges and answer the question – are phalanges short bones?

What Are Phalanges?

Phalanges are the bones that make up the fingers and toes. Each hand and foot contain 14 phalanges, with the exception of the thumb and big toe. The thumb and big toe have only two phalanges, while the remaining fingers and toes have three phalanges each. In total, there are 28 phalanges in the human body. They are long bones, but are they short bones? We’ll answer that question later, but first, let’s explore the anatomy of phalanges in more detail.

The Anatomy of Phalanges

Phalanges are long bones, and each one has three parts: the proximal phalanx, the middle phalanx, and the distal phalanx.

Proximal Phalanx

The proximal phalanx is the part of the bone closest to the hand or foot. It is curved and has a rough surface that attaches to the tendons and ligaments in the finger or toe. The proximal phalanx also contains the articular cartilage, which helps to cushion and protect the joint where the bone meets the metacarpal or metatarsal bone.

Middle Phalanx

The middle phalanx is the second part of the bone, located in the middle of the finger or toe. It is smooth and cylindrical and helps to provide support and flexibility to the digit.

Distal Phalanx

The distal phalanx is the third and final part of the bone. It is the point where the finger or toe ends and is also known as the fingertip or toe tip. The distal phalanx is hard and smooth, protecting the tip of the digit while providing tactile sensation for touch.

Are Phalanges Short Bones?

Short bones are bones that are roughly equal in length and width. They are usually found in places where a lot of movement occurs and need to provide shock absorption. Examples of short bones include the bones in the wrist and ankle.

So, are phalanges short bones? The answer is no. While phalanges are not as long as other bones in the body, they are not classified as short bones. They belong to a class of bones called long bones, which are longer than they are wide and contain a marrow-filled cavity.

Types of Phalanges

Phalanges come in three different types, depending on their location in the finger or toe:

Proximal phalanx

The proximal phalanges are located near the base of the digit, closest to the knuckle. There are five in each hand and foot, one for each finger or toe except the thumb and big toe.

Intermediate phalanx

The intermediate phalanges are found only in the fingers, not the toes. The human body contains four intermediate phalanges, one for each of the fingers that have three phalanges.

Distal phalanx

The distal phalanges sit at the end of each fingertip and the tip of each toe. They are the smallest and most distant bones in the hand and foot and are responsible for sensation in the digits.

Functions of Phalanges

The primary function of phalanges is to provide support for the fingers and toes, allowing us to grasp, manipulate, and interact with the world around us. In addition, phalanges are also involved in the body’s sensory and motor functions. They help transmit sensations such as touch, pressure, and temperature to the brain and are essential for fine motor skills such as playing a musical instrument or typing on a keyboard.

Common Injuries to Phalanges

Phalanges are delicate bones and are susceptible to injuries. Some of the most common injuries to phalanges include:

  • Finger Fractures – Fractures of the phalanges are common, particularly in contact sports such as basketball and football.
  • Mallet Finger – This injury occurs when the tendon that controls the movement of the tip of the finger is damaged, causing the fingertip to droop.
  • Jersey Finger – This injury happens when the finger is bent and then suddenly straightened, causing the tendon responsible for flexing the fingertip to pull away from the bone.
  • Crush Injuries – Crushing injuries to the hand or fingers can cause severe damage to the phalanges and surrounding soft tissue.
  • Sprains – Sprains occur when the ligaments that attach to the phalanges are stretched or torn.


Phalanges are vital bones in the human body, offering support and dexterity to the fingers and toes. While they are not classified as short bones, they play a crucial role in our body’s overall functioning. By understanding the anatomy and function of the phalanges, we can help prevent and treat injuries to these important bones.
