Inguinal hernia or Hesselbach's triangle, an area defined by the edge of the rectus abdominis muscle, the inguinal ligament and the inferior epigastric artery. These hernias are capable of exiting via the superficial inguinal ring and are unable to extend into the scrotum. When a patient suffers a simultaneous direct and indirect hernia on the same side, the result is called a "pantaloon" hernia (because it looks like a pair of pants, with the epigastric vessels in the crotch), and the defects can be repaired separately or together. Since the abdominal walls weaken with age, direct hernias tend to occur in the
Femoral-tibial angle "genu valgum" or "genu varum", the femoral-tibial angle is about 175 degrees. Femoral-tibial angle The femoral-tibial angle is the angle between the femur and tibia. In humans, the two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. In human females the femora converge more than in males because the pelvic bone is wider in females. In the condition "genu valgum" (knock knee) the femurs converge so much that the knees touch one another. The opposite extreme
