What does fusiform swelling mean?
Fusiform means having a spindle-like shape that is wide in the middle and tapers at both ends. It is similar to the lemon-shape, but often implies a focal broadening of a structure that continues from one or both ends, such as an aneurysm on a blood vessel.
What do Bouchard’s nodes indicate?
Bouchard’s nodes are bumps on the joints in the middle of your fingers (the proximal interphalangeal joint, or PIP), and are a sign of advanced finger osteoarthritis (OA), which is a degenerative joint disease.
Which osteoarthritis related deformity is found at the proximal interphalangeal joints?
Bouchard nodes are bony enlargements of the middle joints of the fingers, also known as proximal interphalangeal (PIP) joints.
What fusiform means?
Definition of fusiform : tapering toward each end fusiform bacteria.
What is proximal interphalangeal joint?
The proximal interphalangeal (PIP) joints are commonly known as the middle knuckles of the fingers. Phalanges are the bones in the fingers, thumbs, and toes. A PIP joint is a hinge joint, meaning that it bends and straightens along one plane with little to no side-to-side movement.
What type of joint is the proximal interphalangeal?
Synovial hinge joint
Since the first digit only has a proximal and distal phalanx, the joint between them is simply known as the interphalangeal joint of the thumb….Interphalangeal joints of the hand.
| Type | Synovial hinge joint; uniaxial |
|---|---|
| Movements | Flexion – extension |
What is the proximal interphalangeal joint?
The proximal interphalangeal (PIP) joints are commonly known as the middle knuckles of the fingers. The thumb does not have a PIP joint. In medical terminology, PIP joints are synovial joints located where two phalanges meet. Phalanges are the bones in the fingers, thumbs, and toes.
What is proximal interphalangeal?
The proximal interphalangeal (PIP) joints of the fingers are extremely important for gripping things with hands, more specifically, what is called the ‘power’ grip. Being a hinge joint, the joint’s articular surface and soft tissue do not permit any lateral movement.
What type of joint is the proximal interphalangeal joint?
The proximal interphalangeal joint (PIPJ or PIJ) is located between the proximal and middle phalanges, while the distal interphalangeal joint (DIPJ or DIJ) is found between the middle and distal phalanges….Interphalangeal joints of the hand.
| Type | Synovial hinge joint; uniaxial |
|---|---|
| Blood supply | Proper palmar digital arteries |
| Movements | Flexion – extension |
