Pubalgia
Athletic pubalgia, also called sports hernia, core injury, hockey hernia, hockey groin, Gilmore's groin, or groin disruption is a medical condition of the pubic joint affecting athletes. It is a syndrome characterized by chronic groin pain in athletes and a dilated superficial ring of the inguinal canal. Football and ice hockey players are affected most frequently. Both recreational and professional athletes may be affected. Presentation Symptoms include pain during sports movements, particularly hip extension, and twisting and turning. This pain usually radiates to the adductor muscle region and even the testicles, although it is often difficult for the patient to pin-point the exact location. Following sporting activity the person with athletic pubalgia will be stiff and sore. The day after a match, getting out of bed or a car will be difficult. Any exertion that increases intra-abdominal pressure, such as coughing, sneezing, or sporting activity can cause pain. In the ear ...

Superficial Inguinal Ring
The inguinal canals are the two passages in the anterior abdominal wall of humans and animals which in males convey the spermatic cords and in females the round ligament of the uterus. The inguinal canals are larger and more prominent in males. There is one inguinal canal on each side of the midline. Structure The inguinal canals are situated just above the medial half of the inguinal ligament. In both sexes the canals transmit the ilioinguinal nerves. The canals are approximately 3.75 to 4 cm long. , angled anteroinferiorly and medially. In males, its diameter is normally 2 cm (±1 cm in standard deviation) at the deep inguinal ring.The diameter has been estimated to be ±2.2cm ±1.08cm in Africans, and 2.1 cm ±0.41cm in Europeans. A first-order approximation is to visualize each canal as a cylinder. Walls To help define the boundaries, these canals are often further approximated as boxes with six sides. Not including the two rings, the remaining four sides are usually cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pubic Symphysis
The pubic symphysis is a secondary cartilaginous joint between the left and right superior rami of the pubis of the hip bones. It is in front of and below the urinary bladder. In males, the suspensory ligament of the penis attaches to the pubic symphysis. In females, the pubic symphysis is close to the clitoris. In most adults it can be moved roughly 2 mm and with 1 degree rotation. This increases for women at the time of childbirth. The name comes from the Greek word ''symphysis'', meaning 'growing together'. Structure The pubic symphysis is a nonsynovial amphiarthrodial joint. The width of the pubic symphysis at the front is 3–5 mm greater than its width at the back. This joint is connected by fibrocartilage and may contain a fluid-filled cavity; the center is avascular, possibly due to the nature of the compressive forces passing through this joint, which may lead to harmful vascular disease. The ends of both pubic bones are covered by a thin layer of hyaline ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inguinal Ligament
The inguinal ligament (), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop. Structure The inguinal ligament runs from the anterior superior iliac crest of the ilium to the pubic tubercle of the pubic bone. It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh. There is some dispute over the attachments. Structures that pass deep to the inguinal ligament include: *Psoas major, iliacus, pectineus *Femoral nerve, artery, and vein *Lateral cutaneous nerve of thigh *Lymphatics Function The ligament serves to contain soft tissues as they course anteriorly from the trunk to the lower extremity. This structure demarcates the superior border of the femoral triangle. It demarcates the inferior border of the inguinal triangle. The midpoint of the ingui ...

Incidence (epidemiology)
In epidemiology, incidence is a measure of the probability of occurrence of a given medical condition in a population within a specified period of time. Although sometimes loosely expressed simply as the number of new cases during some time period, it is better expressed as a proportion or a rate with a denominator. Incidence proportion Incidence proportion (IP), also known as cumulative incidence, is defined as the probability that a particular event, such as occurrence of a particular disease, has occurred before a given time. It is calculated dividing the number of new cases during a given period by the number of subjects at risk in the population initially at risk at the beginning of the study. Where the period of time considered is an entire lifetime, the incidence proportion is called lifetime risk. For example, if a population initially contains 1,000 persons and 28 develop a condition since the disease first occurred until two years later, the cumulative incidence prop ...

Stretching
Stretching is a form of physical exercise in which a specific muscle or tendon (or muscle group) is deliberately flexed or stretched in order to improve the muscle's felt elasticity and achieve comfortable muscle tone. The result is a feeling of increased muscle control, flexibility, and range of motion. Stretching is also used therapeutically to alleviate cramps and to improve function in daily activities by increasing range of motion. In its most basic form, stretching is a natural and instinctive activity; it is performed by humans and many other animals. It can be accompanied by yawning. Stretching often occurs instinctively after waking from sleep, after long periods of inactivity, or after exiting confined spaces and areas. Not only vertebrates (mammals and birds), but also spiders were found to exhibit stretching in 2021. Increasing flexibility through stretching is one of the basic tenets of physical fitness. It is common for athletes to stretch before (for warming u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genitofemoral Nerve
The genitofemoral nerve refers to a nerve that is found in the abdomen. Its branches, the genital branch and femoral branch supply sensation to the upper anterior thigh, as well as the skin of the anterior scrotum in males and mons pubis in females. The femoral branch is different from the femoral nerve, which also arises from the lumbar plexus. Anatomy The genitofemoral nerve originates from the upper L1-2 segments of the lumbar plexus. It passes downwards, pierces the psoas major and emerges from its anterior surface. The nerve divides into two branches, the genital branch and the lumboinguinal nerve also known as the femoral branch, both of which then continue downwards and medially to the inguinal and femoral canal respectively. Genital Branch The genital branch continues downward on the surface of the psoas major muscle and then enters the inguinal canal through the deep inguinal ring. In men, the genital branch supplies the cremaster and scrotal skin. In women, the genit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ilioinguinal Nerve
The ilioinguinal nerve is a branch of the first lumbar nerve (L1). It separates from the first lumbar nerve along with the larger iliohypogastric nerve. It emerges from the lateral border of the psoas major just inferior to the iliohypogastric, and passes obliquely across the quadratus lumborum and iliacus. The ilioinguinal nerve then perforates the transversus abdominis near the anterior part of the iliac crest, and communicates with the iliohypogastric nerve between the transversus and the internal oblique muscle. It then pierces the internal oblique muscle, distributing filaments to it, and then accompanies the spermatic cord (in males) or the round ligament of uterus (in females) through the superficial inguinal ring. Its fibres are then distributed to the skin of the upper and medial part of the thigh, and to the following locations in the male and female: * In the male ("anterior scrotal nerve"): to the skin over the root of the penis and upper part of the scrotum. * In the ...

Abdominal Internal Oblique Muscle
The abdominal internal oblique muscle, also internal oblique muscle or interior oblique, is an abdominal muscle in the abdominal wall that lies below the external oblique muscle and just above the transverse abdominal muscle. Structure Its fibers run perpendicular to the external oblique muscle, beginning in the thoracolumbar fascia of the lower back, the anterior 2/3 of the iliac crest (upper part of hip bone) and the lateral half of the inguinal ligament. The muscle fibers run from these points superomedially (up and towards midline) to the muscle's insertions on the inferior borders of the 10th through 12th ribs and the linea alba. In males, the cremaster muscle is also attached to the internal oblique. Nerve supply The internal oblique is supplied by the lower intercostal nerves, as well as the iliohypogastric nerve and the ilioinguinal nerve. Function The internal oblique performs two major functions. Firstly as an accessory muscle of respiration, it acts as an anta ...

Rectus Abdominis Muscle
The rectus abdominis muscle, ( la, straight abdominal) also known as the "abdominal muscle" or simply the "abs", is a paired straight muscle. It is a paired muscle, separated by a midline band of connective tissue called the linea alba. It extends from the pubic symphysis, pubic crest and pubic tubercle inferiorly, to the xiphoid process and costal cartilages of ribs V to VII superiorly. The proximal attachments are the pubic crest and the pubic symphysis. It attaches distally at the costal cartilages of ribs 5-7 and the xiphoid process of the sternum. The rectus abdominis muscle is contained in the rectus sheath, which consists of the aponeuroses of the lateral abdominal muscles. The outer, most lateral line, defining the rectus is the linea semilunaris. Bands of connective tissue traverse the rectus abdominis, separating it into distinct muscle bellies. In the abdomens of people with low body fat, these muscle bellies can be viewed externally. They can appear in sets of as f ...

Conjoint Tendon
The conjoint tendon (previously known as the inguinal aponeurotic falx) is a sheath of connective tissue formed from the lower part of the common aponeurosis of the abdominal internal oblique muscle and the transversus abdominis muscle, joining the muscle to the pelvis. It forms the medial part of the posterior wall of the inguinal canal. Structure The conjoint tendon is formed from the lower part of the common aponeurosis of the abdominal internal oblique muscle and the transversus abdominis muscle. It inserts into the pubic crest and the pectineal line immediately behind the superficial inguinal ring. It is usually conjoint with the tendon of the internal oblique muscle, but they may be separate as well. It forms the medial part of the posterior wall of the inguinal canal. Clinical significance The conjoint tendon serves to protect what would otherwise be a weak point in the abdominal wall. A weakening of the conjoint tendon can precipitate a direct inguinal hernia.

Pubic Tubercle
The pubic tubercle is a prominent tubercle on the superior ramus of the pubis bone of the pelvis. Structure The pubic tubercle is a prominent forward-projecting tubercle on the upper border of the medial portion of the superior ramus of the pubis bone. The inguinal ligament attaches to it. Part of the abdominal external oblique muscle inserts onto it. The inferior epigastric artery passes between the pubic tubercle and the anterior superior iliac spine. The pubic spine is a rough ridge that extends from the pubic tubercle to the upper border of the pubic symphysis. Clinical significance The pubic tubercle may be palpated. It serves as a landmark for local anaesthetic of the genital branch of the genitofemoral nerve, which lies slightly lateral to the pubic tubercle. This may also be used for the obturator nerve The obturator nerve in human anatomy arises from the ventral divisions of the second, third, and fourth lumbar nerves in the lumbar plexus; the branch from t ...
