Objective To present one case of lateral cervical lordosis deformity treated by surgical correction using navigated pedicle screw placement.Methods A 19-year-old male patient with Emery-Dreyfus muscular dystrophy underwent surgical correction using navigated pedicle screw placement. The MRI scanning of the spine showed no abnormalities of the spinal cord. The MRI of extremities revealed a decrease in the muscle mass, and fatty infiltration in the biceps femoris and semimembranosus muscles bilaterally, consistent with the muscle dystrophy pattern. The cardiac function of the patient was evaluated by electrocardiography and echocardiography, and the results were normal. The respiratory function was evaluated by spirometry, which showed restrictive ventilatory defects, however, the arterial O2 saturation was normal. The laminas of vertebrae C2-T5 were bilaterally exposed. Traction or detachment of the interspinous ligament had not been applied. During the exposure, the neck hyperextension was gradually neutral
