Collateral ligaments of the finger joints

Synonym: collateral ligaments of distal interphalangeal joints

Definition

The collateral ligaments of the finger joints are referred to as the "ligamenta collateralia articulationum digitorum manus". They are commonly abbreviated as collateral ligaments.

Anatomy

The collateral ligaments can be divided into the following layers:

Deep layer
- Collateral ligament
Superficial layer
- Accessory collateral ligament
- Phalangoglenoid ligament

Depending on the involved joint, the ligaments may be more or less developed. For example, the phalangoglenoid ligament is typically absent at the distal interphalangeal joint (DIP).
