Lecture on Vitamin D Deficiency: Rickets & Osteomalacia Explained | MBBS

Uncover the critical role of Vitamin D in bone health and learn about the debilitating conditions caused by its deficiency: rickets in children and osteomalacia in adults. This comprehensive medical lecture explains Vitamin D synthesis (involving skin, liver, kidneys, and sunlight), the common causes of deficiency, and details the distinct clinical and radiological features, diagnostic approaches, and treatment strategies for both rickets and osteomalacia. We also briefly touch upon Vitamin D-resistant rickets. Key topics covered in this video: Vitamin D Fundamentals [01:07]: Its importance for bone health and overall cell function; the multi-step synthesis process involving sunlight [01:22, 02:52]. Causes of Vitamin D Deficiency [08:12]: Inadequate sunlight exposure, poor dietary intake, malabsorption issues, and certain medications. Rickets (in Children) [00:45]: Pathophysiology: Affects children before growth plate fusion, leading to soft bones and skeletal deformities. Key Clinical Features: Broad and cup-shaped metaphysis [12:40], muscle weakness, irritability [13:31], frontal bossing, delayed fontanelle closure [13:58], rachitic rosary, Harrison groove [14:40], and bowed legs (genu varum) [17:40]. Osteomalacia (in Adults) [00:45]: Pathophysiology: The adult counterpart to rickets. Key Clinical Features: Bone pain, muscle weakness, and increased fracture risk [31:12]. Specific Radiological Findings [32:16]: Looser zones (incomplete fractures), triradiate pelvis, and protrusio acetabuli. Diagnosis of Vitamin D Deficiency States [19:45]: Based on clinical signs and symptoms, characteristic radiological changes, and blood tests (e.g., low calcium and phosphorus levels [21:50]). Treatment Strategies [23:02]: Addressing the underlying cause, ensuring adequate sunlight, and supplementation with Vitamin D and calcium. Vitamin D-Resistant Rickets [27:55]: A brief overview of this genetic condition.
