Aluminum Toxicity Effects on Bone Metabolism
Summary
Aluminium, a pervasive environmental metal, can accumulate in the skeleton and alter normal bone metabolism. In individuals with impaired renal function or with prolonged occupational exposure, aluminium interferes with the balance between bone formation and resorption. The metal impairs osteoblast activity and reduces alkaline phosphatase function, leading to defective mineralisation and the development of osteomalacia, characterised by softening of bone. At the same time, aluminium may disrupt osteoclast regulation, producing a low‐turnover bone disease that increases fracture risk. Experimental models have shown that aluminium exposure disturbs calcium and phosphate homeostasis, perturbs signalling pathways involved in osteogenesis and promotes deposition of unmineralised osteoid. Clinically, aluminium toxicity manifests as bone pain, increased susceptibility to fractures and, in severe cases, multifocal osteonecrosis. Management strategies focus on reducing exposure, optimising dialysis protocols where relevant, and employing chelation therapies to remove aluminium from the skeleton.

Technical terms
Osteomalacia: Softening of bone tissue due to defective mineralisation leading to increased fracture risk.
Osteonecrosis: Death of bone cells and structural collapse caused by impaired blood supply.
Bone remodelling: Dynamic process of bone formation by osteoblasts and resorption by osteoclasts to maintain skeletal integrity.
Osteoblast: Specialized cell responsible for new bone formation and mineral deposition.
Osteoclast: Specialized cell that breaks down bone tissue during resorption.
Bone mineral density (BMD): Measure of mineral content in bone reflecting its strength and risk of fracture.
