emerges near the lateral border of the psoas major muscle
goes inferior through the anterior abdominal wall, being sub-peritoneal and anterior to the quadratus lumborum muscle until it reaches the iliac crest
goes through the transverse abdominis and the internal oblique muscles
becomes superficial by passing through the superficial inguinal ring anterior to the spermatic cord
supplies:
transverse abdominis and the internal oblique muscles
sensation from the anterior surface of the scrotum and root of the penis in males or labia majora and mons pubis in females, and a small area of the upper anteromedial thigh
patients suffering from ilioinguinal neuralgia will often be forced into a bent-over position to alleviate some of the pain
some patients may have referred pain causing bladder pain, dyspareunia and nocturia
L1 nerve starts its course on the posterior abdominal wall, emerging from the upper border of the psoas major muscle then crosses obliquely to the anterior abdominal wall, running between the anterior abdominal muscles
strain or avulsion of the sartorius muscle from the ASIS
groin strain
generally involve either the iliopsoas muscle, the adductor group, or the gracilis muscle
pain usually radiates down medial aspect of thigh
may result from falling, running, quickly changing directions, as well as kicking or doing the splits (and may be strained during coitus with excessive abduction)
osteitis pubis / gracilis syndrome
a chronic injury that causes radiologically evident resorption of the bone or cartilage of the pubic symphysis due to childbirth, pregnancy (relaxin effect), trauma or repetitive stress from kicking, lifting, running, or jumping
may cause:
loss of flexibility in the groin region, dull aching pain in the groin
a sharp stabbing pain when running, kicking, changing directions, or when standing up or getting out of a car
rectus abdominis strain
fairly common in skaters, hockey players, and swimmers (especially breaststrokers)
sportsman's “hernia” / Gilmore groin
characterized by chronic groin pain that is associated with a dilated superficial inguinal ring
controversial syndrome, the definition, therefore, is any condition that causes persistent unilateral pain in the groin without a demonstrable hernia
pain is located near the pubic tubercle, maximal on the evening of vigorous exercise or on the morning afterward, and exacerbated by activities that increase the intra-abdominal pressure
stress fractures
femoral neck or pubic rami
avulsion fractures
generally occur in adolescents and young adults
history of severe, sudden-onset, and well-localized pain
femoroacetabular impingement
thought to result from abnormal contact stress and joint damage around the hip, most notably from prolonged sitting, leaning forward, getting in and out of a vehicle, or performing a pivoting motion in sports
