Power, volume button and flash not working. Howto force start phone.

My daughter dropped my phone for the nth time, my phone's power, volume buttons won't work. Along with that the flash is also gone. Opened up the phone to see that the strip connecting these to motherboard has gone as a result of battery moving a bit when the phone fell. I can live with it until the part is available, but my phone has switched off now. Is there a way I can force switch on my device. Its a moto x 1052.
