How many position are seen in breech presentation
A. 8 B. 6 C. 4 D. 2
Correct Answer: B. 6
Explanation
In breech presentation, the positions are determined by the relationship of the fetal sacrum to the quadrants of the maternal pelvis.
✅ Number of positions in breech presentation: 4
🔹 The four positions are:
- Left sacro-anterior (LSA)
- Right sacro-anterior (RSA)
- Left sacro-posterior (LSP)
- Right sacro-posterior (RSP)
🔍 Explanation:
- In breech presentation, the presenting part is the buttocks.
- The denominator is the sacrum.
- Depending on whether the sacrum points anteriorly or posteriorly and to the left or right side of the maternal pelvis, four positions are formed.
📝 Key point to remember:
Breech presentation → Denominator = Sacrum → 4 positions
