Transfacet screws (TFS) are an alternative to the classic bilateral pedicular screws (BPS) in addition to anterior (ALIF) or oblique (OLIF) lumbar interbody fusion. Spinal navigation could help the surgeon in technically demanding procedures in order to avoid screw malposition. Although spinal navigation is commonly used in BPS, its contribution in TFS remains unclear. Our aim here was to assess the feasibility of TFS using spinal navigation in addition to anterior lumbar fusion. Five patients suffering from lumbar degenerative disc disease were included. During the same general anaesthesia, we performed successively an ALIF or OLIF and then a TFS according to Boucher technique using spinal navigation (O-arm). No peri-operative complication occurred, and all the screws were successfully positioned (n = 10). All clinical scores (ODI, VAS L and VAS R) improved at 6-month follow-up. Segmental lordosis increased from 6° [2.4°-12°] to 13.6° [8°-17°]. Fusion was achieved for the five patients. TFS using O-arm in addition to ALIF/OLIF is feasible. To confirm our early favourable outcomes on clinical and radiological data, this technique must be evaluated on larger samples of patients.
Transfacet 螺钉（TFS）是经典双侧椎弓根螺钉（BPS）的一种替代方案，除了前路（ALIF）或斜向（OLIF）腰椎椎间融合术。脊柱导航可以帮助外科医生完成技术要求较高的手术，以避免螺钉位置不当。虽然脊柱导航在 BPS 中广泛使用，但在 TFS 中的作用仍不清楚。我们的目的是评估在前路腰椎融合术的基础上使用脊柱导航进行 TFS 的可行性。纳入了 5 例患有腰椎退行性椎间盘疾病的患者。在相同的全身麻醉下，我们成功地进行了一次 ALIF 或 OLIF，然后根据 Boucher 技术使用脊柱导航（O 臂）进行 TFS。无围手术期并发症发生，所有螺钉均成功定位（n=10）。所有临床评分（ODI、L 和 R 侧 VAS）在 6 个月随访时均改善。节段性后凸从 6°[2.4°-12°]增加到 13.6°[8°-17°]。5 例患者均实现了融合。O 臂辅助下的 TFS 联合 ALIF/OLIF 是可行的。为了证实我们在临床和影像学数据方面的早期良好结果，必须在更大的患者样本中评估该技术。
