This study aims to evaluate the safety and effectiveness of INFUSE™ Bone Graft in the real-world setting in Korea.
This study is a prospective, observational, multi-center, post-market surveillance to collect patient data regarding on-label use of INFUSE™ Bone Graft for lumbar fusion via ALIF or OLIF. Commercially available device will be used within its intended use. This study is supposed to be conducted during a period of 4 years with 600 or more cases after the product approval in Korea. According to the standard of care in Korea, the patients will be followed at least 12 months post-surgery.

Ministry of Food and Drug Safety (MFDS) has approved the INFUSE™ Bone Graft for anterior (ALIF) or oblique (OLIF) lumbar interbody spine fusion as a substitute for autogenous bone graft for patients with degenerative disc disease (DDD) who have had at least 6 months of non-operative treatment for this condition.

RECRUITINGAdverse device effects by 12 months post-surgery
Summarize adverse device effects
Time frame: Surgery to 12 months
Fusion status at last assessment by 12 months post-surgery
Radiographic assessment of interbody fusion will be conducted using x-rays and/or CTs
Time frame: Surgery to 12 months

Summarize adverse events of interest
Time frame: Surgery to 12 months
Clinical outcome (ODI) at 6 weeks, 3, 6, 12 months post-surgery
Characterize changes in Oswestry Disability Index (ODI) over time. ODI evaluates how pain is affecting the patient's ability to manage in everyday life, rated on a 0 to 5 scale (higher rating represents greater disability). Improvement of ODI is defined as a decrease in score compared to baseline.
Time frame: Baseline (pre-op) to 12 months
Clinical outcome (VAS) at 6 weeks, 3, 6, 12 months post-surgery
Characterize changes in Visual Analogue Scale (VAS) for back and leg pain over time. VAS evaluates the magnitude of leg and back pain, rated on a 0 to 10 scale (higher rating represents greater pain). Improvement of VAS is defined as a decrease in score compared to baseline.
Time frame: Baseline (pre-op) to 12 months
Rate of neurological success at 6 weeks, 3, 6, 12 months post-surgery
Characterizes changes in neurological status over time. Neurological status is assessed in four sections: motor, sensory, reflexes, and straight leg raising. Following scales were used to evaluate neurological status: motor function (using 0-5 scores; 0= Total Paralysis, 1 = Palpable or Visible Contraction, 2 = Active Movement, Gravity Eliminated, 3 = Active Movement, Against Gravity, 4 = Active Movement, Against Some Resistance and 5 = Active Movement, Against Full Resistance (full strength), sensory function (using 0-2 scores; 0 = Absent, 1 = Impaired, 2 = Normal), reflexes (using 0-2 scores; 0 = Absent or Trace, 1 = Hyper-reflexic, 2 = Normal), and straight leg raise (1 = Positive, 2 = Negative). Overall neurological success will be defined as maintenance or improvement in all sections (motor, sensory, reflexes, and straight leg raising) for the time period evaluated (each element must remain the same or improve).
