A Post Market Surveillance on INFUSE Bone Graft

Recruiting

• Conditions: Intervertebral Disc Degeneration; Lumbar Disc Disease; Spinal Fusion
• Interventions: Device: INFUSE™ Bone Graft

• Registration Number: NCT05299762
• Lead Sponsor: Medtronic Spinal and Biologics

Brief Summary

This study aims to evaluate the safety and effectiveness of INFUSE™ Bone Graft in the real-world setting in Korea.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Patients treated with the INFUSE™ Bone Graft	INFUSE™ Bone Graft	Patients intended to be treated with the INFUSE™ Bone Graft are eligible for enrollment. The investigator screen candidate patients against inclusion/exclusion criteria and enroll a patient only when all inclusion/exclusion criteria meet, and the patient provide written informed consent.

Primary Outcome Measures

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

Secondary Outcome Measures

Name	Time	Method
Adverse events of interest up to 12 months post-surgery	Surgery to 12 months	Summarize adverse events of interest
Rate of neurological success at 6 weeks, 3, 6, 12 months post-surgery	Baseline (pre-op) to 12 months	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).
Clinical outcome (ODI) at 6 weeks, 3, 6, 12 months post-surgery	Baseline (pre-op) to 12 months	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.
Clinical outcome (VAS) at 6 weeks, 3, 6, 12 months post-surgery	Baseline (pre-op) to 12 months	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.
