3. At the end of this chapter, you will
be able to understand the following
topics :
***
 1. Inguinal Ligament
 2. Inguinal Canal
 3. Inguinal hernia
 4. Factors acting and protecting
the inguinal canal

4. INGUINAL LIGAMENT
( poupart’s ligament )
 FORMATION :
External Oblique aponeurosis
(EOA). Inferior border of EOA is
thickened and folded on its inner side
to form inguinal ligament.

7. ATTACHMENTS :
1.FIBRES OF INTERNAL OBLIQUE
MUSCLES
2.FIBRES OF TRANSVERSUS
ABDOMINIS
3.CREMASTOR MUSCLE
4.FASCIA LATA

10. E X T E N S I
O N S :
1. LACUNAR LIGAMENT
2. PECTINEAL LIGAMENT
(LIGAMENT OF COOPER)
3. REFLECTION OF IGUINAL
LIGAMENT

17. SPECIFIC POINTS OF INGUINAL
CANAL :
Inguinal Canal is narrow in
females then males, and so the
males are more prone to inguinal
hernia.
Inguinal canal is straight in
children due undifferentiation of
muscles.

21. CONTENTS OF
INGUINAL CANAL:
A. SPERMATIC CORD IN MALES
AND ROUND LIGAMENT OF
UTERUS IN FEMALES
B. ILIO- INGUINAL NERVE

22. CONTENTS OF SPERMATIC CORD

23. FACTORS
ACTING UPON THE INGUINAL
CANAL / MECHANISM OF
INGUINAL CANAL :

24. 1) Flap - Valve Mechanism (Obliquity of inguinal
canal)
2) Superficial inguinal ring is supported by reflection
of inguinal ligament and also by conjoint tendon
3) Deep inguinal ring is supported by fibres of
internal oblique muscles
4) Shutter Mechanism of internal oblique muscles
5) Ball-Valve Mechanism
6) Slit-Valve Mechanism
7) Hormonal Mechanism

32. Points about direct hernia :
1) Associated with Hesselbach’s Triangle

33. 2) Lateral Direct Hernia : Hernial
Contents come out of lateral part of
Hesselbach’s Triangle
3) Medial Direct Hernia : Hernial
Contents come out of medial part of
Hesselbach’s Triangle

34. TREATMENT OF HERNIA :
SURGICAL TREATMENT :
 HERNIORAPHY
 HERNIOPLASTY
 HERNIOTOMY
