Hernia Eval Takes Practice: Fake it till you make it

Objectives

• Understand anatomy of medial hip and hernias

• Go over inguinal, direct, indirect, Spigelian, and “sports

hernia”

• Scanning protocols for each

Ways to illicit a Hernia

• 1. Bearing down(Valsalva)

– Try blowing on back of hand

• 2. Lifting shoulders

• 3. Bearing down while lifting shoulders

• 4. Coughing

• 5. Standing Evaluation

Femoral Triangle Anatomy

• Femoral Canal

– Femoral artery and vein

– Femoral Br.

Genitofemoral nrv

– lymph nodes

– Femoral nerve is

separate

• More common in

females

– Common post-pardum

Inguinal Canal Anatomy

• Deep and superficial rings

• Females

– Round ligament of Uterus

• Males

– Spermatic cord

– Testicular artery and vein

– Artery to Vas Deferens

– Pampiniform Plexus

– Genital br. Genitofemoral

Nrv

– Vas deferens

– Lymph

– Processus Vaginalis

– Autonomic nerves

Spigelian Hernia

• Spigelian hernia (1-2% of all hernias) is the protrusion of

preperitoneal fat, peritoneal sac, or organ(s) through a congenital

or acquired defect in the spigelian aponeurosis

– the aponeurosis of the transverse abdominal muscle limited by

the linea semilunaris laterally and the lateral edge of the rectus

muscle medially

“Sports Hernia” / Athletic Pubalgia

• Its not athletic pubalgia

• Its not osteitis pubis/ pubic instability

• Its not adductor/gracillis tendinopathy

• Its not rectus abdominus or conjoint

tendinopathy

• Its not a hernia

• It is tranversalis diastasis with deformation

of the spermatic cord or round ligament

Scanning for “Sports Hernia”

• Pubic symphysis

• Adductor tendons

– Esp adductor longus

• Gracilis

• Rectus abdominus

aponeurosis/tendon

• Conjoint tendon

• Direct region

– Laxity of transversalis
