Oblique Lateral Interbody Fusion Versus Minimally Invasive Transforaminal Lumbar Interbody Fusion

• Conditions: Lumbar Spinal Stenosis
• Interventions: Other: Surgery(OLIF and MIS-TLIF)

• Registration Number: NCT04778943
• Lead Sponsor: Tang-Du Hospital

Brief Summary

The investigators will retrospectively study lumbar spinal stenosis patients who underwent OLIF or MIS-TLIF with percutaneous pedicle screw fixation between January 2016 and December 2019.The investigators will measure estimated blood loss, operative time, hospital stay, cost, reoperation, and complication incidence, visual analogue scale (VAS), Oswestry Disability Index (ODI), Japanese Orthopaedic Association (JOA), and Short Form-36 (SF-36) scores, discal and foraminal height, lumbar lordotic angle, and fusion status.The investigators will conduct to evaluate postoperative improvements, complications, and reoperation rates between patients with lumbar spinal stenosis (LSS) undergoing oblique lateral interbody fusion (OLIF) or minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF).
