Distal interphalangeal joint is the joint between distal phalanx and middle phalan.
Distal interphalangeal joint is a bicondylar ginglymus joint.
The joint is very well stabilized collateral ligaments on medial and lateral side and the volar plate
There are two types of collateral ligaments -
- The proper collateral ligaments which insert on the lateral tubercles at the base of distal phalanx.
- The accessory collateral ligaments attach distally to the lateral margins of the volar plate.Distal interphalangeal joint stability is maintained by articular congruity, the dynamic balance of flexor and extensor tendons and ligaments.
