    Abstract:
    BACKGROUND: Anterior, direct lateral, and transforaminal lumbar interbody fusions (ALIF, DLIF, and TLIF) are usually combined with posterior fixation to treat degenerative spinal diseases. Outcomes of ALIF, TLIF, or DLIF combined with a new wedge-shaped interfacet cage plate have not been reported. We assessed early clinical outcomes of patients treated with interbody fusion and facet fixation using a titanium wedge-shaped cage plate. METHODS: This retrospective observational cohort study included patients (n = 80) who underwent 1-level interbody fusion and facet joint fixation via ALIF (n = 24) or DLIF (n = 26) with bilateral facet fixation or TLIF with ipsilateral pedicle screws and contralateral facet fixation (n = 30). Duration of surgery, estimated blood loss, pain (visual analog scale), Oswestry Disability Index (ODI) scores, and Macnab score were assessed up to 12 months after surgery. RESULTS: All patients had a significant decrease in pain scores (P < 0.01) and an increase in ODI scores (P < 0.01), without significant differences between treatment groups. Most surgical outcomes were excellent or good (n = 75, 93.8%) with 5 patients (6.2%) having satisfactory outcomes. Within 2 months, all patients returned to their previous work (66, 82.5%) or lighter work (14, 17.5%). Two patients had fusion failure requiring reoperation. CONCLUSIONS: Facet fixation with the wedge-shaped cage plate was associated with minimal soft tissue damage and a low level of postoperative pain. ALIF, DLIF, and TLIF combined with this technique showed good early postoperative clinical and radiologic outcomes. Further studies are needed to assess long-term results and compare them with other fusion methods.
