The invention provides an osteotomy checking and testing method, checking and testing equipment, a readable storage medium and an orthopedic surgery system. The method comprises the steps of firstly,obtaining information of a calculated position of a current osteotomy plane by the osteotomy checking and testing equipment, further by programming the information of the preset position of the osteotomy plane, determining position error between the information of the calculated position and the information of the preset position, if the position error exceeds a preset value, performing calculating and obtaining repositioning information, transmitting the repositioning information to a mechanical arm, and performing repositioning. According to the such configuration, the position errors between the current osteotomy plane formed after primary osteotomy is performed and the planned preset osteotomy plane are compared and distinguished, the mechanical arm is repositioned, and the osteotomy plane is corrected for the second time, so that the precision of a final osteotomy plane can be improved. In addition, through the mechanical arm, repositioning is performed, and the osteotomy plane iscorrected for the second time, so that the condition that an additional bone nail is used for repeatedly fixing a guiding tool to a bone is avoided, the wounded surfaces of a patient can be reduced,and the surgery time can be shortened.
