Brief Summary:
The purpose of this single-arm observational study is to observe and document clinical outcomes of the OLIF25™ and OLIF51™ procedures in patients diagnosed with degenerative disc disease or degenerative scoliosis, and report the rate of adverse events of interest through the 24 months follow-up visit.

Intervention Details:
  • Procedure: Oblique Lateral Interbody Fusion
    The oblique lateral interbody fusion (OLIF) procedures at L2-L5 (OLIF25™) and L5-S1 (OLIF51™) is a minimally invasive surgical option for degenerative lumbar disease. This approach allows for psoas-preserving access to the lumbar spine and minimizes the need to reposition the patient during surgery for accessing additional spinal levels for the interbody fusion portion of the procedure
    Other Name: OLIF

Primary Outcome Measures :
  1. Back and Leg Pain Measured by Visual Analogue Scales (VAS) [ Time Frame: 24 months ]
  2. Oswestry Disability Index (ODI) [ Time Frame: 24 months ]
  3. European Quality of Life-5 Dimensions (EQ-5D) self-report questionnaire [ Time Frame: 24 months ]
  4. Neurological deficits assessed by neurological status [ Time Frame: 24 months ]
    Neurological status is based on seven components of measurements: Motor function; Sensory function; Deep Tendon reflexes; Sympathetic Exam; Claudication; Urinary bladder retention/Bowel retention; and Sexual Dysfunction.

  5. Rate of adverse events [ Time Frame: 24 months ]

Other Outcome Measures:
  1. Surgical Data [ Time Frame: Day 0 to Day 5 ]
    Surgical data include mean blood loss, operative time, and length of hospital stay (LOS).

  2. Work status [ Time Frame: 24 months ]
  3. Spino-Pelvic Measurements by X-ray [ Time Frame: 24 months ]
