The Finnish translation of the SBST is linguistically accurate and has been adapted to the Finnish-speaking population. It showed to be a valid and reliable instrument and comparable with the original English version. Therefore, it may be used in clinical work with Finnish LBP patients.

Purpose The purpose of this study is to report a new mini-invasive technique to remove an intracranial bullet in a child by using O-arm for intraoperative neuronavigation. Case report A 14-year-old refugee boy had suffered a shooting injury 4 years earlier. O-arm imaging-assisted neuronavigation during craniotomy was performed in order to remove a bullet from the intracranial space in a paediatric patient. Conclusion Navigation using O-arm is a feasible method in removing a foreign material in a child and gave an accurate location of the bullet in the adopted surgical operation position without significant imaging artefacts.
