Narrative:

In cruise with autopilot on; we encountered wake turbulence near buf; one bump and that was all. Clear skies with no traffic in sight nor reported in the vicinity. When the purser called to tell us he was submitting the cabin write ups; which was about 30 minutes after the bump; he also mentioned he was writing up that he may have tweaked his back during the turbulence. The purser appeared to continue to do his duties without difficulty.
