To compare the clinical outcome between unilateral and bilateral pedicle screw fixation in minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF) for the treatment of lumbar degenerative diseases. ⋯ Using unilateral or bilateral pedicle screw fixation in MIS-TLIF for lumbar degenerative diseases can achieve the same clinical effects, and there was no significant difference in complication rate. Unilateral pedicle screw fixation is safer than bilateral fixation because of less operative time and blood loss. However, the number and quality of the literatures may result in low reliability, so greater sample size and high quality RCTs are needed in future.
