Summary
Ischiofemoral impingement, a hip pain cause, involves abnormal femur and ischium contact. This condition presents with gradual groin or buttock pain, often mistaken for other hip issues.
Area of Science:
- Orthopedics
- Radiology
- Sports Medicine
Background:
- Femoroacetabular impingement is a recognized cause of hip pain.
- Ischiofemoral impingement is an emerging condition involving abnormal contact between the femur's lesser trochanter and the ischium.
- This condition can mimic other hip pathologies like iliopsoas tendonitis or bursitis.
Purpose of the Study:
- To describe the characteristics of ischiofemoral impingement in the native hip joint.
- To differentiate ischiofemoral impingement from other causes of hip pain.
- To highlight diagnostic indicators and imaging findings.
Main Methods:
- Review of clinical presentations and diagnostic imaging (MRI) of patients with suspected ischiofemoral impingement.
- Correlation of patient symptoms with specific hip movements (extension, adduction, external rotation).
- Distinguishing MRI findings of inflammation and edema in the ischiofemoral space and quadratus femoris muscle.
Main Results:
- Ischiofemoral impingement presents with gradual onset groin and/or posterior buttock pain.
- Pain is exacerbated by hip extension, adduction, and external rotation.
- MRI reveals inflammation and edema in the ischiofemoral space and quadratus femoris, distinct from acute tears.
Conclusions:
- Ischiofemoral impingement is a distinct cause of hip pain in the unreplaced joint.
- Clinical examination and MRI are crucial for diagnosis.
- Further research is needed to understand its prevalence and management in the native hip.

01:16Bones of the Lower Limb: Femur and Patella
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 neck...
01:20Muscles that Move the Thigh
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 fascia...

01:20Arteries of Lower Limbs
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
01:19Abdominal Regions and Quadrants
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 quadrants...

01:23Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...
