Objective To evaluate the outcomes of oblique lumbar interbody fusion (OLIF) combined with anterolateral single‐rod screw fixation (AF) in treating two‐segment lumbar degenerative disc disease (LDDD) and to determine whether AF can maintain the surgical results. Methods A retrospective analysis was performed on patients who underwent OLIF combined with AF (OLIF‐AF) for LDDD at the L3‐5 levels between October 2017 and May 2018. A total of 84 patients, including 44 males and 40 females, with a mean age of 62.8 ± 6.8 years, who completed the 12‐month follow‐up were eventually enrolled. Clinical outcomes, including the Oswestry Disability Index (ODI), visual analog scale (VAS) score for the low back and leg, and radiographic parameters, including the cross‐sectional area (CSA) of the spinal canal, disc height (DH), foraminal height (FH), degree of upper vertebral slippage (DUVS), segmental lumbar lordosis (SL), fusion rate, and lumbar lordosis (LL), were recorded before surgery and 1 and 12 months after surgery. Surgical‐related complications, including cage subsidence (CS), were also evaluated. The local radiographic parameters were compared between L3‐4 and L4‐5. The clinical results and all radiographic parameters were compared between patients with and without CS. Results Significant improvements were observed in radiographic parameters 1 day postoperatively (p
