  2. Palmar plate - Wikipedia

    en.wikipedia.org/wiki/Palmar_plate

    These bands help stabilise the volar plates over the metacarpal heads. [2] In contrast to the volar plates of the MCP joints of the fingers, the volar plate of the thumb MCP joint is a thick structure firmly attached to the base of the proximal phalanx. It forms the bottom of a two-sided box, the sides of which are made up of the collateral ...

    This is called a "palmar plate, or volar plate injury". [3] The palmar plate forms a semi-rigid floor and the collateral ligaments the walls in a mobile box which moves together with the distal part of the joint and provides stability to the joint during its entire range of motion.

  4. Annular ligaments of fingers - Wikipedia

    As a general rule, the A1, A3, and A5 pulleys in the fingers are "joint pulleys" that originate from the volar plate on the volar aspect of the metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints, respectively.

  5. Palmar carpometacarpal ligaments - Wikipedia

    en.wikipedia.org/wiki/Palmar_carpometacarpal...

    The palmar carpometacarpal ligaments (or volar) are a series of bands on the palmar surface of the carpometacarpal joints that connect the carpal bones to the second through fifth metacarpal bones. The second metacarpal is connected to the trapezium. The third metacarpal is connected to the trapezium, to the capitate, and to the hamate. The ...

  6. Collateral ligaments of metacarpophalangeal joints - Wikipedia

    en.wikipedia.org/wiki/Collateral_ligaments_of...

    A collateral ligament flanks each MCP joint - one on either side. Each attaches proximally at the head of the metacarpal bone, and distally at the base of the phalynx. Each extends obliquely in a palmar direction from its proximal attachment to its distal attachment. [2]

  7. Swan neck deformity - Wikipedia

    en.wikipedia.org/wiki/Swan_neck_deformity

    Swan neck deformity has many of possible causes arising from the DIP, PIP, or even the MCP joints. In all cases, there is a stretching of the volar plate at the PIP joint to allow hyperextension, plus some damage to the attachment of the extensor tendon to the base of the distal phalanx that produces a hyperflexed mallet finger.

    In Klein’s case, a Postal Service spokeswoman said, the problem is the road. Hillman Ridge is paved but narrows to a width slightly larger than a pickup truck as it approaches Klein’s property.

  9. Metacarpal bones - Wikipedia

    en.wikipedia.org/wiki/Metacarpal_bones

    Left hand shown with thumb on left. The metacarpals form a transverse arch to which the rigid row of distal carpal bones are fixed. The peripheral metacarpals (those of the thumb and little finger) form the sides of the cup of the palmar gutter and as they are brought together they deepen this concavity.
