2. Introduction of pelvis
Definition of pelvis
Pelvic bone
Pelvic joints
Functions of pelvis
True and false pelvis
Pelvic inlet ,pelvic outlet ,pelvic
brim
Pelvic diameters
Types of pelvis
Pelvic ligaments
3. Pelvis is a basin like structure
which connects the spine to lower
limbs .
Its an important part of skeletal sys
It transmit weight of the trunt to
the legs .
4.
5. WORD PELVIS means ,BASIN
PELVIC is the region of the trunk
located below the abdomen
6.
7. Four pelvic bones ;
Two innominate bones
One saccrum
One coccyx
One innominat bone is comprised
of one illium , one ischium n one
pubic bone
8.
9.
10. FOUR PELIC JOINTS
Two sacroiliac joints ; strongest
one
One symphysis pubic joint
One sacro coccygeal joint
11. WOMEN pelvis is adapted for child
bearing n bcz of its increased width
n rounded brim women are less
speedy than man
Pelvis transmists weight of trunk to
legs ,acting as a bridge
saccrum transmit the cauda equina
n distribute the nerves to various
part of the pelvis
12. FALSE PELVIS OR GREATER PELVIS
located
superiorly ,it provide support of the
lower abdominal viscera such as
illium and sigmoid colon
It has little obtetric value
TRUE PELVIS OR LESSER PELVIS
located
inferiorly ,within the lesser pelvis
reside the pelvic cavity and pelvic
viscera .
15. Three diameters of pelvic inlet are
1 anterioposterior diameter
diameter line from
sacral promontary to upper border of
symphysis pubis , abt 11 cm
2 oblique diameter
diameter line from
sacroiliac joint to the illiopectineal
eminence on the opposite side of the
pelvic ,measures 12cm
16. 3 transverse diameter
diameter line between
the points of illiopectineal lines
and measures 13cm
17.
18.
19. THREE DIAMETERS OF PELIV
OUTLET
1 Anterioposterior diameter
this is a line from
lower of symphysis pubis to the
sacrococcygeal joint and
measurement is 11.5cm
2 oblique diameter
this is said to
between the obturator foramen
and sacrospinous ligament
.measurement is 12cm
20. Transverse diameter
between the two
ischial spines and measurement is
10-11cm
note ;
All diameters inlet and outlet are
measured fo this purpose how many
space is available for passage of
fetus.
