PURPOSE
Percutaneous spine procedures may occasionally be difficult and subject to complications. Navigation using a dynamic reference base (DRB) may ease the procedure. Yet, besides other shortcomings, its fixation demands additional incisions and thereby defies the percutaneous character of the procedure.
METHODS
A new concept of atraumatic referencing was invented including a special epiDRB. The accuracy of navigated needle placement in soft tissue and bone was experimentally scrutinised. Axial and pin-point deviations from the planned trajectory were investigated with a CT-based 3D computer system. Clinical evaluation in a series of ten patients was also done.
RESULTS
The new epiDRB proved convenient and reliable. Its fixation to the skin with adhesive foil provided a stable reference for navigation that improves the workflow of percutaneous interventions, reduces radiation exposure and helps avoid complications.
CONCLUSIONS
Percutaneous spine interventions can be safely and accurately navigated using epiDRB with minimal trauma or radiation exposure and without additional skin incisions.
目的
经皮脊柱手术偶尔可能会很困难，并容易出现并发症。使用动态参考基座（DRB）进行导航可能会简化手术过程。然而，除了其他缺点外，其固定需要额外的切口，从而违背了手术的经皮特性。
方法
发明了一种新的无创伤参照概念，包括特殊的 epiDRB。通过基于 CT 的 3D 计算机系统对软组织和骨骼中导航针的放置准确性进行了实验研究。还对十名患者的临床评估进行了研究。
结果
新型 epiDRB 证明了其方便性和可靠性。其通过粘性箔片固定在皮肤上，为导航提供了一个稳定的参考，改善了经皮介入手术的工作流程，减少了辐射暴露，并有助于避免并发症。
结论
使用 epiDRB 可以安全、准确地对经皮脊柱手术进行导航，创伤最小或辐射暴露最小，无需额外的皮肤切口。
