A device for alleviating the complaints of a trapeziometacarpal joint disease from the degenerative, inflammatory, and rheumatic spectrum. The load on the trapeziometacarpal joint changed by arthrosis can be dynamically relived by means of said device. The device includes a splint, which is detachably fastened to the wrist on one side and reaches under the first thumb joint of the diseased hand on the other side. The splint accommodates the thumb in a natural resting position of thumb. If the thumb is bent, then, below the thumb joint, the thumb stresses the splint against the retainer fastened to the wrist as a result of the radial motion or bending of the thumb and thereby lifts the trapeziometacarpal joint minimally from a usual seat thereof. A gap thus arises between the joint bodies that engage with each other. The joint surfaces no longer painfully rub against each other.
