  • Inguinofemoral Area
    Inguinofemoral Area Inguinal Canal Anatomy of the Inguinal Canal in Infants and Children There are readily apparent differences between the inguinal canals of infants and adults. In infants, the canal is short (1 to 1.5 cm), and the internal and external rings are nearly superimposed upon one another. Scarpa's fascia is so well developed that the surgeon may mistake it for the aponeurosis of the external oblique muscle, resulting in treating a superficial ectopic testicle as an inguinal cryptorchidism. There also may be a layer of fat between the fascia and the aponeurosis. We remind surgeons of the statement of White that the external oblique fascia has not been reached as long as fat is encountered. In a newborn with an indirect inguinal hernia, there is nothing wrong with the posterior wall of the inguinal canal. Removal of the sac, therefore, is the only justifiable procedure. However, it is extremely difficult to estimate the weakness of the newborn's posterior inguinal wall by palpation. If a defect is suspected, a few interrupted permanent sutures might be used to perform the repair. Adult Anatomy of the Inguinal Canal The inguinal canal in the adult is an oblique rift in the lower part of the anterior abdominal wall. It measures approximately 4 cm in length. It is located 2 to 4 cm above the inguinal ligament, between the opening of the external (superficial) and internal (deep) inguinal rings. The boundaries of the inguinal canal are as follows: Anterior: The anterior boundary is the aponeurosis of the external oblique muscle and, more laterally, the internal oblique muscle.

  • Describe the Anatomy of the Inguinal Canal. How May Direct and Indirect Hernias Be Differentiated Anatomically
    Describe the anatomy of the inguinal canal. How may direct and indirect hernias be differentiated anatomically. How may they present clinically? Essentially, the function of the inguinal canal is for the passage of the spermatic cord from the scrotum to the abdominal cavity. It would be unreasonable to have a single opening through the abdominal wall, as contents of the abdomen would prolapse through it each time the intraabdominal pressure was raised. To prevent this, the route for passage must be sufficiently tight. This is achieved by passing through the inguinal canal, whose features allow the passage without prolapse under normal conditions. The inguinal canal is approximately 4 cm long and is directed obliquely inferomedially through the inferior part of the anterolateral abdominal wall. The canal lies parallel and 2-4 cm superior to the medial half of the inguinal ligament. This ligament extends from the anterior superior iliac spine to the pubic tubercle. It is the lower free edge of the external oblique aponeurosis. The main occupant of the inguinal canal is the spermatic cord in males and the round ligament of the uterus in females. They are functionally and developmentally distinct structures that happen to occur in the same location. The canal also transmits the blood and lymphatic vessels and the ilioinguinal nerve (L1 collateral) from the lumbar plexus forming within psoas major muscle. The inguinal canal has openings at either end – the deep and superficial inguinal rings. The deep (internal) inguinal ring is the entrance to the inguinal canal. It is the site of an outpouching of the transversalis fascia.

SUMMARY: The anatomy of the psoas minor muscle in human beings has frequently been correlated with ethnic and racial characteristics. The present study had the aim of investigating the anatomy of the psoas minor, by observing its occurrence, distal insertion points, relationship with the psoas major muscle and the relationship between its tendon and muscle portions. Twenty-two human fetuses were used (eleven of each gender), fixed in 10% formol solution that had been perfused through the umbilical artery. The psoas minor muscle was found in eight male fetuses: seven bilaterally and one unilaterally, in the right hemicorpus. Five female fetuses presented the psoas minor muscle: three bilaterally and two unilaterally, one in the right and one in the left hemicorpus. The muscle was independent, inconstant, with unilateral or bilateral presence, with distal insertions at different anatomical points, and its tendon portion was always longer than the belly of the muscle. KEY WORDS: Psoas Muscles; Muscle, Skeletal; Anatomy; Gender Identity.

    Large-Scale Analysis of Iliopsoas Muscle Volumes in the UK Biobank Julie Fitzpatrick1*, Nicolas Basty1*+, Madeleine Cule2, Yi Liu2, Jimmy D. Bell1, E. Louise Thomas1, and Brandon Whitcher1 1Research Centre for Optimal Health, School of Life Sciences, University of Westminster, London, UK 2Calico Life Sciences LLC, South San Francisco, California, USA *joint first authors +email: [email protected] ABSTRACT Psoas muscle measurements are frequently used as markers of sarcopenia and predictors of health. Manually measured cross-sectional areas are most commonly used, but there is a lack of consistency regarding the position of the measurement and manual annotations are not practical for large population studies. We have developed a fully automated method to measure iliopsoas muscle volume (comprised of the psoas and iliacus muscles) using a convolutional neural network. Magnetic resonance images were obtained from the UK Biobank for 5,000 male and female participants, balanced for age, gender and BMI. Ninety manual annotations were available for model training and validation. The model showed excellent performance against out-of-sample data (dice score coefficient of 0.912 ± 0.018). Iliopsoas muscle volumes were successfully measured in all 5,000 participants. Iliopsoas volume was greater in male compared with female subjects. There was a small but significant asymmetry between left and right iliopsoas muscle volumes. We also found that iliopsoas volume was significantly related to height, BMI and age, and that there was an acceleration in muscle volume decrease in men with age. Our method provides a robust technique for measuring iliopsoas muscle volume that can be applied to large cohorts.

Box 30197 00100 Nairobi Email: [email protected] SUMMARY Hernia surgery is in many ways the quintessential case for demonstrating anatomy in action. Laparoscopic hernia surgery has a more recent history compared to open surgery. The demand for the procedure is increasing. The indications for laparoscopic herniorrhaphy include bilateral disease, recurrence following anterior repairs and patient preference. Anatomy of the lower anterolateral abdominal wall appreciated from a posterior profile compounds the challenge of a steep learning curve for the procedure. The iliopubic tract and Cooper’s ligaments, less obvious to anterior surgeons, are important sites for mesh fixation for laparoscopic surgeons. Their neural and vascular relations continue to receive plenty of mention in hernia literature as explanations for troublesome procedure-related morbidities. The one ‘rectangle’ (trapezoid of disaster), one ‘circle’ (of death) and two ‘triangles’ (of doom, of pain) geometric concepts denote application of anatomy in mapping the danger areas of the groin where dissection and staples for fixation should be minimized.
