In the PIP joint (the middle joint between the main knuckle and the DIP joint), the strongest ligament is the volar plate. This ligament connects the proximal phalanx to the middle phalanx on the palm side of the joint. The ligament tightens as the joint is straightened and keeps the PIP joint from bending back too far (hyperextending).

2017年5月22日 · Our purpose is to review the detailed anatomy and key components of the volar retinacular elements of the hand, their etymology, and their most recent descriptions. The objective also is to organize these structures into systems, which can be helpful for learners to assimilate into a practical anatomical guide.

An important structure in the volar aspect of the wrist is the Carpal tunnel. Boundaries of the carpal tunnel: Carpal bones dorsally and flexor retinaculum and transverse carpal ligament volarly.

2023年6月12日 · The volar plate: Volar plate ligaments connect your first two finger bones (phalanges) together on each finger. They run under your bones on the palmar side of your hand and keep your fingers from bending too far back when you extend them.

2024年1月26日 · The hand can be conveniently divided into the palmar (volar) and dorsal parts. The volar portion of the hand contains the major digital nerves, the flexor tendons, and the muscles that allow finger movement.

2023年8月8日 · The arteries of the volar surface of the hand consist of two systems: the superficial volar arch and the deep volar arch. These arches and their branches form the basis of an extensive collateral circulation that is responsible for providing oxygenated blood to all parts of the hand and fingers.

Our purpose is to review the detailed anatomy and key components of the volar retinacular elements of the hand, their etymology, and their most recent descriptions. The objective also is to organize these structures into. From the *Hand Surgery Division, Integris Baptist Medical Center, Oklahoma City, OK.

What is a volar plate injury? A volar plate injury happens when your finger joint is bent too far backwards (hyperextension). This causes the ligament and cartilage tissue on the palm side of your joint (volar plate) to tear or become detached from the bone.

Areas of the human hand include: The palm (volar), which is the central region of the anterior part of the hand, located superficially to the metacarpus. The skin in this area contains dermal papillae to increase friction, such as are also present on the fingers and used for fingerprints.

The volar plate (VP) is critical to the stability of the proximal interphalangeal joint. This study clarifies the macro-and micro-architectural structure of the VP and correlates these findings with its functional properties.
