Episode Title:

🔑 Pediatric Rickets Simplified — Types, Features, Mnemonics & PYQs

Episode Description (for Spotify):

Rickets keeps coming back in NEET-PG & INI-CET — both in short stems and clinical vignettes. In this episode, we break it down into bite-sized, exam-friendly pearls with easy mnemonics:

📌 What You’ll Learn:

1. ​ Definition & Basics

• ​ Rickets = defective mineralization of growth plate (children).
• ​ Osteomalacia = defective mineralization of osteoid (adults).

1. ​ Types of Rickets

• ​ Nutritional (Vit D deficiency) → most common.
• ​ Vitamin D–dependent (Type I & II)
• ​ Vitamin D–resistant (Hereditary hypophosphatemic rickets)
• ​ Renal rickets (CKD, renal tubular acidosis).

1. ​ Clinical Features (Mnemonic: RICKETS)

• ​ Rosary (rachitic rosary at costochondral junction)
• ​ Inward bowing of legs (genu varum/valgum)
• ​ Craniotabes + delayed closure of fontanelle
• ​ Kyphoscoliosis & knock knees
• ​ Epiphyseal widening + cupping/fraying of metaphysis
• ​ Tetany (hypocalcemia)
• ​ Stomach protrusion (potbelly, Harrison’s sulcus)

1. ​ Radiology Mnemonic: WFR

• ​ Widened growth plates
• ​ Fraying of metaphysis
• ​ Rachitic rosary

1. ​ Important Lab Patterns

• ​ Nutritional Rickets: ↓Ca, ↓PO₄, ↑ALP, ↑PTH
• ​ Vit D–dependent I: ↓1α-hydroxylase → low calcitriol
• ​ Vit D–dependent II: End-organ resistance → high calcitriol
• ​ Hypophosphatemic: Low phosphate, normal calcium

1. ​ Memory Pegs for Types:

• ​ Type I: Hydroxylase defect — think “I can’t Hydroxylate.”
• ​ Type II: Receptor defect — think “II = Resistant.”

1. ​ PYQ Connections

• ​ NEET-PG 2021: child with frontal bossing + rachitic rosary → diagnosis?
• ​ INI-CET 2022: lab values with low phosphate, normal calcium → hypophosphatemic rickets.
• ​ NEET-PG 2018: child with multiple fractures, vit D supplementation not working → Vit D-dependent Type II.

🧠 Key Takeaway:

“One table (Ca, PO₄, ALP, PTH) + one mnemonic (RICKETS) = 3–4 sure-shot questions.”
