What is the correct post-reduction treatment for dorsal DIP/PIP dislocations?

The appropriate post-reduction treatment for dorsal dislocations at the distal interphalangeal (DIP) and proximal interphalangeal (PIP) joints involves splinting in 20-30 degrees of flexion for a duration of 10-21 days. This position is crucial as it accommodates the anatomical healing requirements of the joint, reduces tension on the collateral ligaments, and helps in recapturing the articular congruity that may have been disrupted during the dislocation event.

Splinting the joints in this slightly flexed position offers both stability and the necessary environment for healing. By preventing hyperextension and allowing for some degree of active and passive range of motion in a controlled manner, the healing process can progress with minimal risk of stiffness or complications due to immobilization in an undesirable position.

The duration of 10-21 days is sufficient to allow soft tissue structures to recover while also permitting early mobilization strategies that can be employed post-immobilization for rehabilitation. Overall, this treatment method fosters recovery while aiming to maximize functional outcomes and minimize long-term complications such as chronic instability or joint stiffness.
