Metatarsal bones

You have five long bones in your foot.

They sit in the middle of your foot. These bones are between your ankle and your toes.

Each bone has a different length. The second bone is the longest. The first bone is the shortest.

These bones help you move. They connect to the bones in your ankle. They also connect to your toes.

Sometimes these bones can break. This can happen during sports. Some people call these breakages march fractures.

Special shoes can help protect your feet. You can stay safe while you play.

You have five long bones in the middle of your foot. These are called metatarsal bones.

They sit between your ankle bones and your toes. Each bone has three main parts. They have a base, a body, and a head. The body is the long middle part. It is shaped like a prism.

These bones are numbered one through five. The first bone is by your big toe. The fifth bone is by your pinky toe. In humans, the second bone is the longest. The first bone is the shortest.

Metatarsals help you move. They connect to ankle bones at joints. They also connect to your toes. Muscles attach to these bones to help you walk.

Sometimes these bones can break. This is called a fracture. Some people call them march fractures. This name comes from soldiers who march for a long time. These breaks often happen in sports. Soccer players may break them. Modern soccer boots are very light. This means they may give less protection. You can use special shoes to stay safe.

The metatarsal bones are a group of five long bones. They sit in the middle of your foot. These bones are located between your ankle bones and your toes.

The group of bones is called the metatarsus. They are very important for how you move. These bones are similar to the metacarpal bones in your hand.

In humans, the bones have different lengths. The second bone is the longest of the group. The third, fourth, and fifth bones follow in size. The first metatarsal is the shortest bone.

Each bone has a specific shape and structure. Every metatarsal has a base, a body, and a head. The base is the part closest to your ankle. The body is the long middle part. It is shaped like a prism and curves slightly.

The head is the part that connects to your toes. The base connects to the tarsal bones at the tarsometatarsal joints. The head connects to the toes at the metatarsophalangeal joints. The bases also connect to each other at the intermetatarsal joints. This structure helps your foot stay strong while you walk.

These bones are numbered from one to five. We start numbering from the side with the big toe. The first metatarsal is on the medial side. The fifth metatarsal is on the other side.

During growth, these bones have special growth plates. Most of these plates are at the head of the bone. However, the first metatarsal has its growth plate at the base. Sometimes, an extra growth plate can grow on the head of the first bone. This is a common thing to see.

Many muscles attach to these bones to help you move. For example, the tibialis anterior muscle attaches to the first metatarsal. The peroneus longus muscle attaches to a bump on the first bone.

Other muscles like the interossei attach to the sides of the bones. These muscles help your feet work during movement. These bones can also get hurt during sports. Stress fractures are a common injury in sports. They make up about 16% of sports injuries. These are sometimes called march fractures because of soldiers who march for a long time.

Metatarsal injuries often happen to soccer players. This might be because modern soccer boots are very lightweight. These light boots may provide less protection for the foot.

In 2010, some players tested a new kind of sock. This sock had a rubber silicone pad to protect the top of the foot. You can also use safety footwear to stay safe. Some shoes have built-in guards to protect the metatarsals. These guards help prevent breaks during hard activities. Knowing how these bones work helps us protect them.

The metatarsal bones form the central structure of the human midfoot. Collectively, this group of five long bones is known as the metatarsus. These bones occupy the space between the tarsal bones, which make up the ankle and heel, and the phalanges, which are the toes.

Because they connect the ankle to the toes, they are essential for weight-bearing and movement. In humans, these bones are functionally similar to the metacarpal bones found in the hand. While a bovine hind leg contains only two metatarsals, humans rely on five to support the complex mechanics of walking and balance.

Each metatarsal bone follows a specific anatomical structure consisting of three main parts. The proximal end is called the base, which is wedge-shaped. The middle section is the shaft, or body, which is prismoid in form. The distal end is known as the head.

The body of the bone tapers gradually from the tarsal end to the phalangeal end. It also features a longitudinal curve that is concave on the bottom and slightly convex on the top. The head presents a convex articular surface that is oblong when viewed from above. On the bottom, the head has a groove for the passage of flexor tendons.

These bones are identified by number rather than individual names. We number them from the medial side, which is the side of the great toe. The first metatarsal is the most medial, followed by the second, third, fourth, and fifth. Interestingly, the bones are not equal in size. In humans, the second metatarsal is the longest. The descending order of length is the second, third, fourth, fifth, and finally the first metatarsal.

During development, growth plates are located distally on most metatarsals. However, the first metatarsal is unique because its growth plate is located proximally. It is also common to find an accessory growth plate on the distal end of the first metatarsal.

Movement in the foot is made possible through various articulations, or joints. The bases of the metatarsals connect to the tarsal bones at the tarsometatarsal joints. Specifically, the first metatarsal joins the medial cuneiform and partly the intermediate cuneiform. The second metatarsal connects with all three cuneiforms. The third meets the lateral cuneiform, while the fourth connects to the lateral cuneiform and the cuboid. The fifth metatarsal articulates with the cuboid.

Additionally, the heads of the bones connect to the first row of phalanges at the metatarsophalangeal joints. The bases also connect to one another at the intermetatarsal joints.

Muscles attach to these bones at specific points to facilitate movement. For example, the tibialis anterior muscle inserts at the basis of the first metatarsal. The peroneus longus attaches to the tuberosity of the first metatarsal. On the fifth metatarsal, the peroneus brevis attaches to its tuberosity, and the flexor digiti minimi brevis originates from its basis.

Other muscles, such as the dorsal and plantar interossei, attach to the sides of the bones. These attachments allow the muscles to pull on the bones, creating the controlled motions needed for locomotion.

Because the metatarsals support so much weight, they are susceptible to injury. Stress fractures are a significant concern and account for approximately 16% of injuries related to sports. These are often called march fractures because they were traditionally associated with military recruits performing long marches. The second and third metatarsals are frequently injured because they remain fixed while a person walks. The fifth metatarsal may fracture if the foot undergoes oversupination during movement.

These injuries highlight the intense physical demands placed on the midfoot structure.

Modern equipment can influence the frequency of these bone injuries. For instance, association football (soccer) players often experience metatarsal breaks. Researchers have attributed this to the lightweight design of modern football boots, which offer less protection. In 2010, some players began testing specialized socks that included a rubber silicone pad to protect the top of the foot. To prevent such injuries, safety footwear can be used, often featuring built-in or removable metatarsal guards. Understanding the anatomy and vulnerabilities of the metatarsus is vital for both medical care and athletic safety.
