1. A method, comprising:
providing a spinal interbody fusion system comprising an implant device and an insertion tool, wherein the implant device comprises a housing, a first driving mechanism and a second driving mechanism each being operable to expand and/or contract the housing along a first lateral side and a second lateral side of the housing respectively, and the insertion tool comprises a chassis defining a first channel and a second channel, a first driving shaft received in the first channel, a second driving shaft received in the second channel, a first measuring system configured to measure a rotational movement of the first driving shaft in the first channel, a second measuring system configured to measure a rotational movement of the second driving shaft in the second channel, wherein each of the first driving shaft and the second driving shaft is independently and separately rotatable in the first channel and the second channel respectively;
connecting the insertion tool with the implant device;
inserting the implant device between adjacent vertebrae in a patient;
applying torque to the first and second driving mechanisms of the implant device independently using the first driving shaft and the second driving shaft via the first and second channels of the insertion tool respectively, whereby an amount of expansion and/or contraction of the housing along the first lateral side is independently adjusted relative to an amount of expansion and/or contraction of the housing along the second lateral side, the torque applied to the first and second driving mechanisms of the implant device being measured by the first and second measuring systems respectively.
