The so-called "functional position" of the hand for immobilization of an injured hand or finger may in many cases lead to stiffness of the finger joints by shrinkage of the joint capsule and -ligaments. This process can be minimized by immobilization of the small finger joints in a position where the most important ligament structures are under maximum tension. Basically this is the intrinsic-plus-position for the long fingers and palmar abduction and extension of the thumb. Immobilization in this so-called protective position of the hand minimizes immobilization damages of the small finger joints. The underlying basic principles of the anatomy are explained.
