What is a distal phalanx of foot?

What is a distal phalanx of foot?

The distal phalanges (foot) are located at the end of each toe. Three phalangeal bones make up each digit, articulating with each other at bending joints. The distal phalanges come at the end, right below the toenail.

What is a phalange bone?

Phalanges. The 14 bones that are found in the fingers of each hand and also in the toes of each foot. Each finger has 3 phalanges (the distal, middle, and proximal); the thumb only has 2. Metacarpal bones. The 5 bones that compose the middle part of the hand.

What are second phalanx of the foot?

The phalanges (single: phalanx) of the feet are the tubular bones of the toes. The second to fifth toes each contain a proximal, middle and distal phalanx whereas the great toe (hallux) only contains a proximal and distal phalanx.

What is the function of phalanges in the foot?

The proximal phalanges are critical in allowing the toes to bend properly. As such, they are important in activities ranging from walking to jumping. These bones are also important in lateral movements, helping you to navigate irregular surfaces and maintain your balance.

Why does my distal phalanx hurt?

The DIP joint is the first knuckle from the top of the finger. It connects the distal phalanx and middle phalanx, which are the two bones at the tip of the finger. Experiencing DIP joint pain is often a sign of a type of arthritis, such as osteoarthritis or psoriatic arthritis.

Where is the distal phalanx located?

The distal phalanx of the finger is the distal or third of the three bones in each finger when counting from the hand to the tip of the finger. The distal phalanx has a joint just with the middle phalanx. On the tip of the phalanx is a bulbous tuft of bone that helps give the finger its rounded appearance.

How many distal phalanges are there?

Each hand has five distal phalanges, which look shorter and slightly thicker compared to the previous two sets. Each distal phalanx has a base, body and head. The base has a double articular facet which matches the shape of the head of the middle phalanx. The distal phalanges have a smooth and round dorsal surface.

Why is the phalanges important?

The phalanges play a vital role in the movement and flexibility of digits, as well as the whole hand. These bones allow us to flex and fold the fingers and thumb to hold or pick something up, and carry on all daily activities like using a phone, typing, eating and so on.

What is the difference between phalanx and toe?

The phalanges are long bones in the foot located distal to the metatarsals. Like in the hand, each toe consists of three phalanges, which are named the proximal, middle and distal phalanges. However, the hallux (great toe) only has two phalanges, a proximal and a distal one.

What does PIP and DIP mean?

“proximal interphalangeal joints” (PIJ or PIP), those between the first (also called proximal) and second (intermediate) phalanges. “distal interphalangeal joints” (DIJ or DIP), those between the second (intermediate) and third (distal) phalanges.

What does it mean when you can’t move your big toe?

If you can’t bend your big toe, you may have a condition called hallux rigidus that is caused when degenerative arthritis increases deterioration of the big toe joint. Risk factors for developing hallux rigidus include having poorly treated flat feet, gout, and other arthritic conditions.

Which finger is the distal phalanx?

The thumb distal phalanx is a short bone with a rounded tuft at the end that makes a joint with the proximal phalanx. The bulbous tuft at the end of the bone gives the thumb its rounded end. This bone supports the thumb nail.

What do the distal phalanges do?

The distal phalanges are the fingertips. This is why the term terminal phalanges may be interchangeable with distal phalanges. These bones are unlike their counterparts in the finger. Their main purpose involves supporting the sensitive flesh of the fingertip, where a high number of nerve endings are situated.

What is bottom of foot called?

The bottom of the foot is known as the sole. The padded area on the bottom of the foot is known as the plantar aspect.

What arthritis affects PIP?

The most common symptoms of osteoarthritis are stiffness, swelling, and pain. Bony nodules may develop at the middle (PIP) and end (DIP) joints of the finger. A deep, aching pain at the base of your thumb is typical of osteoarthritis in the basilar joint.

What causes PIP joint pain?

Osteoarthritis or autoimmune arthritis, such as rheumatoid arthritis, can damage a PIP joint over time. A PIP joint can also degenerate due to post-traumatic arthritis caused by a past injury. Failure to promptly treat an injured PIP joint increases the likelihood of developing post-traumatic arthritis.
