While on descent; passing 12;000' at night windshield shattered. Ran QRH in compliance with all Company policies. While I was putting away the QRH under the trim wheel shortly thereafter; Captain disengaged autopilot and instinctively activated trim while my hand was still near trim wheel. RESULT: Fractured left hand of First Officer.FACTORS: I don't think he saw my hand down there. I had just said 'checklist complete;' and I can't remember if he said 'autopilot off' or not. Both of those statements could have triggered an extra level of caution; but honestly; it has never held that meaning for me before in this context. Fairly busy in approach stage of flight (radios; configuration; running checklists).
A B737 NG Captain manually activated the elevator trim and broke the First Officer's hand as the trim wheel turned while he stowed the QRH checklist away under the wheel following its use for a shattered windshield.
