PUBIC SYMPHYSIS PROJECTION

  1. CHAMBERLAIN METHOD (PA PROJECTION)

2
New cards

CHAMBERLAIN METHOD (PA PROJECTION)

PP: Upright; standing on two blocks
• First exposure: remove one blocks; one leg hangs with no muscular resistance
• Second exposure: replace support under foot that was hanging; remove the opposite one; second leg hanging free

RP: Pubic symphysis

CR: ┴

SS: Pubic symphysis
