The results and main steps of an analytic calculation of radiative-recoil corrections of order α(Zα)5(m/M)m to the Lamb shift in hydrogen are presented. The calculations are performed in the infrared safe Yennie gauge. The discrepancy between two previous numerical calculations of these corrections existing in the literature is resolved. Our result eliminates the largest source of the theoretical uncertainty in the magnitude of the deuterium-hydrogen isotope shift.
