Free-hand technique is one of the techniques used by spine surgeon during pedicle screw instrumentation surgical correction spinal deformities, including scoliosis. The previous studies showed that this safe. However, some inherent factors may influence its outcomes, breaching which potentially violates cord and other intimate structures. To confirm safety accuracy technique, additional study measuring breach rate placement in scoliosis mandatory.We performed a retrospective patients with adolescent idiopathic (AIS) from Fatmawati General Hospital, Jakarta, treated for period 2017-2018 using free-hand instrumentation. Post-operative computed tomography scan (CT scan) was analyzed to measure medial lateral breaches. P < 0.05 deemed be statistically significant.A total 94 screws six female AIS were included our study. Overall occurred 33% instrumented screws, majority it low-grade breach. Of breached 20% 12% respectively. There no differences overall, medial, breaches between thoracic lumbar vertebrae (P > 0.05). Medial significantly higher middle segment compared segments = 0.048). Risk 3 times convex side deformity 0.012), whereas risk 4.6 concave 0.021).The violation within safe zone, neurological sequelae. Our found effective method AIS. Some
