    Abstract:
    BACKGROUND: The lateral interbody fusion (LIF) has gained popularity for the surgical treatment of lumbar degenerative spondylolisthesis (DS), however, LIF often requires the position change for posterior screwing. We have performed the single-position lateral surgery of oblique lateral interbody fusion (OLIF) and posterior screwing (OLIF-LPF). The present study compared the clinical and radiologic results between OLIF-LPF and minimally invasive transforaminal interbody fusion (MIS-TLIF). METHODS: A total of 142 patients underwent either OLIF-LPF (92 cases) or MIS-TLIF (50 cases) for L3 or L4 DS. The average age was 72 and 70 years old, respectively. The OLIF-LPF was performed in right decubitus position with allograft and percutaneous modified cortical bone trajectory screws (mCBT). The MIS-TLIF utilized a single 4 cm midline incision, allograft, boomerang cage and mCBTs. The operation time, estimated blood loss, and serum CRP levels were recorded. JOABPEQ effectiveness rate (%), Visual Analogue Scale (VAS), fusion rate, segmental radiologic alignment, and complications were also evaluated. RESULTS: Average follow-up period was 31 and 57 months in OLIF-LPF and MIS-TLIF, respectively. The average operation time and estimated blood loss were 108min, 51 ml and 104 min and 69 ml, respectively. OLIF-LPF demonstrated significantly higher values of mental health domain of JOABPEQ effectiveness rate and VAS improvement of leg pain than those in MIS-TLIF. The less correction loss of posterior disc height was demonstrated in OLIF-LPF. The fusion rate and symptomatic adjacent segment degeneration (ASD) were statistically equivalent between two groups. CONCLUSIONS: The single-position surgery of OLIF combined with posterior screwing serves as a safe, minimally invasive and effective surgical modality without the need of position change. It provides comparable fusion rate, segmental radiologic alignment, and symptomatic adjacent segment degeneration to MIS-TLIF surgery.
