Muscles that Move the Thigh01:20

Muscles that Move the Thigh

3.4K
The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar...

Appendicitis-I: Introduction

3.4K
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

9.1K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Abdominal Regions and Quadrants

19.3K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...

Ultrasonography01:17

Ultrasonography

8.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Summary
This summary is machine-generated.

Extrarticular impingement, including subspine, ischiofemoral, and psoas impingement, frequently causes groin pain in athletes. Understanding these conditions is key for effective diagnosis and treatment.

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Anatomy

Background:

  • Extrarticular impingement is an increasingly recognized cause of athletic groin pain.
  • Specific types include subspine impingement (prominent anterior inferior iliac spine), ischiofemoral impingement (reduced lesser trochanter space), and psoas impingement (psoas tendon/labrum interaction).

Purpose of the Study:

  • To review the extrarticular causes of impingement contributing to groin pain in athletes.
  • To elucidate the anatomical basis and presentation of subspine, ischiofemoral, and psoas impingement.

Main Methods:

  • Literature review of extrarticular impingement syndromes.
  • Analysis of anatomical relationships and clinical presentations.

Main Results:

  • Subspine impingement is linked to an anterior inferior iliac spine (AIIS) anomaly.
  • Ischiofemoral impingement involves decreased space between the ischium and lesser trochanter.
  • Psoas impingement occurs due to the psoas tendon's interaction with anterior hip structures.

Conclusions:

  • Extrarticular impingement is a significant differential diagnosis for groin pain in athletes.
  • Anatomical variations in the AIIS, ischium, and surrounding soft tissues contribute to these painful conditions.
