Bone homeostasis and osteoporosis-related challenges in spinal fusion in the vertebrae. This figure illustrates the key biological & mechanical challenges affecting spinal fusion in elderly patients. In normal vertebrae, MSCs within the bone marrow differentiate into osteoblasts, which mature into osteocytes and maintain bone formation. Concurrently, hematopoietic stem cells (HSCs) differentiate into OCs, which mediate bone resorption. Under normal vascular conditions, bone formation and resorption remain balanced. In aged vertebrae, MSCs exhibit impaired osteogenic differentiation, coupled with reduced vascular supply, leading to decreased bone formation. Meanwhile, osteoblasts and osteocytes secrete increased levels of RANKL (receptor activator of nuclear factor kappa-B ligand), disrupting the OPG (osteoprotegerin)/RANKL balance and excessively activating OCs, resulting in accelerated bone resorption. Osteoporosis and degenerative disc changes contribute to fragility in the elderly.
