Osteogenesis Imperfecta क्या है?
What is Osteogenesis Imperfecta?
Osteogenesis Imperfecta (OI) एक genetic disorder है जिसे "Brittle Bone Disease" भी कहते हैं। Collagen defect के कारण bones कमजोर होती हैं और आसानी से टूट जाती हैं। Birth से ही condition present होती है। NO CURE - लेकिन treatment से quality of life improve होती है।
🎯 Key Facts!
Brittle Bone Disease! 1:15,000 to 1:20,000 births। Genetic mutation causes। Collagen Type 1 defect। Range: mild से severe। Multiple fractures common! Treatment improves outcomes। Lifelong condition!
📊 Key Statistics:
जन्मों में
सबसे common
जीवनकाल में
आनुवंशिक
🧬 What Happens?
Collagen Type 1 में defect - bones की main building block।
Causes: COL1A1 or COL1A2 gene mutations। कभी-कभी spontaneous mutation। Autosomal dominant या recessive।
Result: Weak bones → frequent fractures। Abnormal bone structure। Low bone mass। Blue sclera। Hearing loss।
🔑 Important: Genetic disorder! Birth से present। Can be inherited या new mutation। Affects bone formation throughout life।
⚠️ Common Misconceptions:
- Myth: OI बढ़ती है। Fact: Genetic - birth से present! Severity varies।
- Myth: सभी OI children wheelchair में। Fact: Many walk independently!
- Myth: Cure possible। Fact: Lifelong condition - but treatable!
- Myth: सभी severe। Fact: Wide spectrum - mild से severe!
Osteogenesis Imperfecta (OI) is genetic disorder known as "Brittle Bone Disease". Collagen defect causes weak bones that break easily. Present from birth. NO CURE - but treatment improves quality of life.
🎯 Key Facts!
Most common inherited bone disorder! 1:15,000 births. Collagen Type 1 defect. Multiple types. Frequent fractures. Early intervention crucial!
📊 Stats:
OI के प्रकार (Types)
Types of OI
🎯 8 Main Types Based on Severity!
Type I (Mildest) | Type II (Lethal) | Type III (Severe) | Type IV (Moderate) | Types V-VIII (Rare)
📋 OI Types Detailed:
1. Type I OI (50%)
MILDEST AND MOST COMMON! Blue sclera। Few fractures (mostly childhood)। Normal या near-normal height। Hearing loss possible। Good prognosis! Independent life। Mild bone deformity। Teeth may be normal या brittle (DI)।
2. Type II OI
MOST SEVERE - LETHAL! Usually stillborn या die shortly after birth। Extreme bone fragility। Multiple fractures at birth। Severe deformities। Small chest। Respiratory failure। Prenatal diagnosis possible! Genetic counseling important।
3. Type III OI
SEVERE - PROGRESSIVE! Multiple fractures from birth। Short stature (very short)। Severe bone deformities। Blue/grey sclera। Dentinogenesis imperfecta common। Wheelchair dependent often। Respiratory issues। Hearing loss। Require intensive care।
4. Type IV OI
MODERATE SEVERITY! White या light blue sclera। Moderate bone deformities। Short stature (mild-moderate)। Variable fractures। Many walk independently! Dentinogenesis imperfecta common। Bowing of bones। Better prognosis than Type III।
5. Types V-VIII OI
RARE TYPES! Recently identified। Different genetic mutations। Type V: Calcified interosseous membrane। Type VI: Specific bone pathology। Types VII-VIII: Recessive inheritance। Research ongoing! Similar management to Types III-IV।
✅ Type I vs Type III Comparison:
Type I: Mild। Blue sclera। Few fractures। Normal height possible। Independent। Type III: Severe। Very short। Many fractures। Deformities। Wheelchair often। Both need specialized care!
🧬 Genetics & Inheritance:
Types I, IV: Autosomal dominant - 50% chance। Type II: Usually new mutation या autosomal recessive। Types VII-VIII: Autosomal recessive - 25% chance। Genetic testing available! Counseling recommended for families। Prenatal diagnosis possible।

लक्षण (Symptoms)
Symptoms & Signs
🚨 Main Features of OI!
Frequent Fractures | Blue Sclera | Bone Deformities | Short Stature | Hearing Loss
🦴 Skeletal Symptoms:
Frequent Fractures
HALLMARK SIGN! Minor trauma से fractures। Sometimes spontaneous fractures। Birth से लेकर puberty तक most common। Long bones (femur, tibia)। Decrease after puberty। 100+ fractures possible in lifetime। Proper handling crucial!
Bone Deformities
Bowing of long bones। Curved legs/arms। Scoliosis (spine curvature)। Pectus deformity (chest)। Progressive with repeated fractures। Growth plate damage। Short stature common। Surgery may be needed।
Short Stature
Variable by type। Type I: normal या slightly short। Type III: very short (severe)। Type IV: mild-moderate short। Due to: Bone deformities। Compression fractures। Growth plate issues। Adult height affected।
Dentinogenesis Imperfecta
Weak teeth (DI)। Grey/brown discoloration। Wear down easily। Chip/break easily। Common in Types III, IV। Dental care important। Crowns/veneers needed। Prevent infections।
👁️ Other Features:
💙 Blue Sclera (Common!)
Blue या grey tint to whites of eyes। Due to thin sclera। Collagen defect causes। Most prominent in Type I। May fade with age। NOT harmful। Diagnostic clue!
👂 Hearing Loss (30-50%)
Usually starts in 20s-30s। Conductive या sensorineural। Progressive। Small ear bone (stapes) affected। Treatment: Hearing aids। Surgery (stapedectomy)। Regular audiometry। Early detection important!
⚠️ Other Complications:
