PELVIC

A. Solid part : Pelvic bone

B. Soft part : Pelvic ligament & muscle

A. PELVIC BONE 2 Innominate bone : - Os illium- Os ischium- Os pubic

Sacrum Coccyx

posterior in order to wider the pelvic outlet

Pelvic Inlet/Pelvic brim Area bordered

by: Promontorium Sacrum Linea inominata Ramus Superior

ossis Pubis Uper border of

Symphisis pubis

Pelvic outletArea bordered by: Ujung bawah

Sacrum Tulang Tuber

Ischiadica Sacro-coccygeal Lower border of

symphisis pubis

Normal pelvic measurement

Distansia Spinarum

Distansia Cristarum

Distansia Cristarum: 28—29 cm

Distansia Spinarum: 25—26 cm

Inside Pelvic measurement

• Conjugata Diagonalis = 12,5—13cm

• Conjugata Vera = CD – (1,5—2cm)

• Conjugata Obstetrika = terpendek

Hodge line Hodge I: imagination line drawn from

promontorium to the upper border of symphisis pubis

Hodge II: parallel with hodge I measured from lower border of symphisis

Hodge III: parallel with hodge II, measured from spina ischiadica

Hodge IV: parallel with hodge III, measured from coccyx tip

H IH II

H IIIH IV

B. PELVIC LIGAMENT & MUSCLE LIGAMENT connect the pelvic joint

Ligament interpubic pada symphysis pubis Ligament sacro iliaca Ligament sacro-coccygeal Ligament sacro-tuberous Ligament sacro spinosus

PELVIC MUSCLEThe inner aspect of the bony pelvis is covered

with muscles: Above the brim --- iliacus & psoas

Sidewalls ---- obturator internus & its fascia

Post wall ---- pyriformis

Pelvic floor ---- lavator ani & coccygeus

PELVIC MUSCLE

Conjugata Vera

Sacral promontory

Left sacro-iliac joint

Iliopectineal line

Sacrospinous ligament

Sacrotuberous ligament

Symphysis pubis

Ischial tuberosity

Ischial spine

PELVIC EXAMINATION• X-Ray• Jangka Panggul• Distansia Cristarum• Distansia Spinarum• Conjugata eksterna/Bouldeloque:

distance between upper border symphysis pubis with prosessus spinosus lumbal 5. the normal measurement 18—20 cm

• Vaginal Touché

Vaginal Touché Examintion Promontorium touched/not Conjugata Vera normal/not Spina Ischiadica prominent/not Arkus pubis wide/narrow Sakrum curve/not

Note: •Touched Promontory usually indicated narrow pelvic•Height ≤145 cm also indicated narrow pelvic

Differentiation between female and male pelvic

Pelvic Shape

PELVIC SHAPE 1-GYNECOID Typical female pelvis found in 50% of

women Rounded—slightly oval inlet Straight pelvic sidewalls with roomy pelvic

cavity Good sacral curve Ischial spines are not prominent Pubic arch is wide

PELVIC SHAPE2-ANDROID Typical male pelvis found in 1/3 white

women 1/6 non-white Pelvic brim is heart shaped Pelvis funnels from above downwards

(convergent sidewalls) Narrow pubic arch Prominent spines

PELVIC SHAPE3-ANTHROPOID 25% white women & 50% nonwhite Pelvic brim APD > TD Long & narrow pelvic canal with long sacrum Straight pelvic sidewalls4-PLATYPELLOID 3% of women Pelvic brim TD >>>APD kidney shape Sacral promontory pushed forwards

Pelvic Shape DeviationA. Panggul Naegele

B. Panggul Rakhitis

C. Panggul Skoliosis

D. Panggul Kifosis

E. -”- dari Samping

F. Panggul Osteomalasia

G. Panggul Spondilolistesis

H. Panggul Robert

Causes of pelvic deviation Congenital:- Narrow palvic- Simple flat- Funnel (narrow outlet)- Assimilation Disease :- Rachitic- Osteomalasia- TBC- Lordosis- Skoliosis- Kifosis- Spondilosis

Deviation impact Prolonged labor CPD (Chepalo Pelvic Disproportion) Breech presentation Infertility

POST TEST Pelvic anatomy contains of what kind of part? What can you mention about Pelvic bone? What can you mention about Pelvic

ligament? What can you mention about pelvic muscle? What do you know about pelvic shape? What would happen if the pelvic is not

normal in measurement?
