 Over time, the handcuff case may cause a rupture in the L-5 disc of the back , and cause pinching of the Sciatic nerve — thus numbing the officer's left leg, severely affecting his or her running ability.Some officers choose to carry their handcuffs in the small of back position, but do not utilize a handcuff case, meaning that one side of the handcuffs is pushed between the officer's belt and trousers (or simply tucked into his or her trousers), and the other side is allowed to hang loose on the outside.This method is often utilized by plain clothes officers who do not wear a belt of any sort, and therefore are unable to use a proper handcuff case.
