What is the primary treatment after reduction of a dorsal PIP or DIP dislocation?

The primary treatment after the reduction of a dorsal proximal interphalangeal (PIP) or distal interphalangeal (DIP) dislocation is immobilization. After reduction, it is essential to stabilize the joint to allow for proper healing and prevent re-dislocation. Immobilization helps in reducing pain, limiting movement that could aggravate the injury, and allowing soft tissues such as ligaments and tendons to recover.

Typically, a splint or cast may be used to maintain the necessary position of the joint and to prevent stress during the initial healing phase. This approach is a standard practice in sports medicine, ensuring optimal recovery and return to function for the athlete.

While applying ice can help manage swelling and pain, and warm compresses might facilitate blood flow and comfort, these actions do not provide the necessary stabilization that is crucial right after a dislocation has been reduced. Immediate physical therapy is also typically not recommended immediately following reduction due to the need for stabilization first. Therefore, immobilization is the correct approach to take after reducing a PIP or DIP dislocation.
