Abstract
Sickle cell disease (SCD) is a mono-genic disorder causing chronic hemolysis, anemia, and vaso-occlusion, leading to musculoskeletal complications such as osteonecrosis, osteoporosis, and bone fractures affecting 50-70% SCD patients. These complications result from a complex interplay of genetic and physiological factors, including abnormal hemoglobin production, chronic inflammation, and oxidative stress. This review discusses the pathophysiology, pre-clinical symptoms, and clinical manifestations of musculoskeletal complications in SCD, as well as current treatment options, including pharmacological interventions, surgical procedures, and bone marrow transplantation. Early detection of pre-clinical symptoms is crucial to prevent progression. Pharmacological interventions (analgesics, anti-inflammatory agents, bone-modifying agents and hydroxyurea), surgical interventions (core decompression, bone grafting, joint replacement and osteotomy) and supportive measures enhance mobility, strength and well-being. A multidisciplinary approach is essential for optimal care, and early diagnosis and management are crucial to prevent long-term damage and improve outcomes. Future research directions include targeted therapies, biomarker investigation and infrastructure development to improve outcomes for SCD individuals with musculoskeletal complications.
