There are only few reports of the advantages of three-dimensional (3D) computed tomography based navigation system being used for spinal tumor excision. A 33 year old male presented in the clinic with mid-back ache with change in posture. Radiology suggested an osteoid osteoma involving the superior articular process of the D11 vertebra. Accurate localization and complete extirpation of the lesion were performed using a translaminar approach with O-arm Navigation. 3D navigation with the O-arm system provided an easy and accurate localization of the lesion, reducing the risk of instability subsequently and avoiding instrumented stabilization. This technique also provided for histopathological confirmation of the diagnosis.
