Study Details

The goal of this clinical trial is to determine the change in VBQ score, T score, TBS, and Hounsfield Units (HU) after 3-6 months of treatment with abaloparatide in osteoporotic patients who will undergo spinal fusion and decompression for lumbar degenerative disease. The main question\[s\] it aims to answer is: Does abaloparatide improve bone density in these patients, as defined by VBQ score compared to traditional methods such as DEXA and Hounsfield Units Does abaloparatide reduce the incidence of postoperative mechanical complications, including adjacent segment disease, subsidence, and proximal junctional kyphosis (PKJ)? Participants will undergo a presurgical assessments and trained in clinic on the subcutaneous application of abaloparatide. Prior to treatment, patients will have baseline assessments, including a lumbar MRI, DEXA scan, and lumbar CT. Post-surgically, participants will administer abaloparatide and return to clinic after 3-6 months for follow-up assessments including a new MRI, lumbar CT, and DEXA scan. Patients will be followed for up to 2 years postoperatively to identify complications such as adjacent segment disease, pseudarthrosis, failure of instrumentation, and PJK.
