Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Patients that decide to undergo an Anterior Lumbar Interbody Fusion (ALIF) surgery \[a surgical procedure that joins two or more lumbar vertebrae (small bones of the spine) together into one solid bony structure by approaching the spine through the abdomen (front of the body) and placing a bone graft in between the vertebral bodies where the disc usually lies\], are invited to participate in an orthopaedic research study.
This study will compare patients that have been treated with an anterior lumbar interbody fusion using InQu Bone Graft Extender \& Substitute to published data for a stand alone spinal fusion surgery, where InFuse bone graft is placed between the transverse processes \[small bony projections off the right and left side of each bone in your spine\] of the affected vertebrae.
X-rays, daily activities, and how patients are doing will be evaluated at specific time points during this study.
The hypothesis of this study is that patients diagnosed with degenerative disc disease treated with an anterior lumbar interbody fusion, anterior only surgical approach (incision through the abdomen), using InQu Bone Graft Extender and Substitute and instrumented fixation have comparable radiographic (x-rays), functional (daily activities), and clinical (how the patient is doing) outcomes when compared to published data for use of InFuse in stand-alone fusion.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Data will be collected by chart review to include pre-operative, surgical, functional, post-operative, and radiographic imaging charted data, collected as part of the routine clinical visit, and standard of care.
Follow-up data will include newly charted clinical, functional, and radiographic imaging data, including dynamic x-rays and CT scans to be obtained prospectively at a minimum of one (1) year post-operatively. During the routine post-surgical visits, patient pain outcomes are measured using the Visual Analog Scale (VAS) for back and leg pain, function is measured by the Oswestry Disability Index (ODI) and Short Form-12 Version 2 (SF-12 Version 2 Health Survey). A physician investigator will also perform routine clinical evaluations.
The patients will undergo standard radiographic procedures to obtain x-rays (including lateral, anterior-posterior, and dynamic flexion/extension) as part of the standard of care. A CT scan will be performed for research purposes as indicated in the protocol follow-up procedure. X-rays and CT scans will be evaluated by an independent radiologist and a physician investigator to determine anterior fusion status and the status of the anterior hardware constructs.
The National Center of Innovation for Biomaterials in Orthopaedic Research and Medical Metric, Inc. will assist with imaging analysis of x-rays and CTs.
ISTO Technologies, Inc. will be providing a grant to cover costs associated with the research components of this study.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Degenerative Disc Disease
Patients diagnosed with degenerative disc disease, meeting all eligibility requirements (please refer to inclusion/exclusion criteria), will be asked to participate in this study. A one-level or two-level anterior lumbar interbody fusion surgery using InQu Bone Graft Extender and Substitute, mixed with BMAC (bone marrow aspirate concentrate) as autograft, with Synthes Spinal Instrumentation will be recommended to the patient. If patients elect to proceed with surgery using the prescribed surgical components, they will be offered enrollment into the study. If the patient opts to use a different bone graft, or other spinal instrumentation, then the patient will not meet all inclusion criteria and will not be offered the opportunity to enroll in this study.
One-level or two-level anterior lumbar interbody fusion
Patients electing to receive a one-level or two-level, anterior approach only (incision through the front), lumbar interbody fusion in order to treat degenerative disc disease (at one or two levels in the spine), and meeting all other inclusion criteria, are eligible for enrollment into the study.
InQu Bone Graft Extender and Substitute mixed with BMAC
Surgeries utilizing InQu Bone Graft Extender and Substitute during the anterior lumbar interbody fusion surgical procedure will be elected for inclusion. InQu will be mixed with BMAC (bone marrow aspirate concentrate), which will be prepared using the SmartPRep2 centrifuge. Patients opting to use a grafting alternative will not meet inclusion criteria, and will not be eligible to enroll in this study.
Synthes Spinal Instrumentation
Synthes Spinal Instrumentation will be used during surgery as spinal stabilization.
