What is pitting in MRI?

What is pitting in MRI?

Abstract. Herniation pits are small benign lucent oval lesions within the anterior aspect of the superolateral femoral neck and were first described in 1982 by Michael J. Pitt.

What is a Pitt’s Pit?

Pitt pit refers to an oval or round lucency in the anterosuperior aspect of the femoral neck, just distal to the articular surface. It represents a herniation of synovium or soft tissues into the bone through a cortical defect, hence the alternate name synovial herniation pit.

What is synovial herniation pit?

Herniation pits are small benign oval lesions that were reported to be always lying within the super-lateral femoral neck, and were first described in 1982 by Michael J. Pitt. They are usually a unilateral incidental finding along with asymptomatic course.

What does cam deformity mean?

A cam deformity is characterized by extra bone formation at the anterolateral head–neck junction resulting in a non-spherical cam-shaped deformity5. It is forced into the acetabulum during flexion and internal rotation of the hip, a process referred to as cam impingement6, 7.

What is cam type femoroacetabular impingement?

Cam-type femoroacetabular impingement (FAI) is a known cause of groin pain and a condition that can give rise to osteoarthritis of the hip (1). Patients suffering from this condition are mainly young and experience pain when the hip is moved through internal rotation and adduction at 90° of hip flexion.

What is the femoral neck?

The femoral neck is the most common location for a hip fracture. Your hip is a ball and socket joint where your upper leg meets your pelvis. At the top of your femur (which is your thigh bone) is the femoral head. This is the “ball” that sits in the socket. Just below the femoral head is the femoral neck.

What is a synovium?

The synovium, which is also sometimes called the stratum synoviale or synovial stratum, is connective tissue that lines the inside of the joint capsule. A joint capsule, also called an articular capsule, is a bubble-like structure that surrounds joints such as the shoulder, elbow, wrist, hand, knee, foot and ankle.

What happens when the femoral head collapse?

Osteonecrosis of the hip develops when the blood supply to the femoral head is disrupted. Without adequate nourishment, the bone in the head of the femur dies and gradually collapses. As a result, the articular cartilage covering the hip bones also collapses, leading to disabling arthritis.

What does Pitt Pit stand for in medical terms?

Dr Daniel J Bell ◉ and A.Prof Frank Gaillard ◉ ◈ et al. Pitt pit refers to an oval or round lucency in the anterosuperior aspect of the femoral neck, just distal to the articular surface. It represents a herniation of synovium or soft tissues into the bone through a cortical defect, hence the alternate name synovial herniation pit.

What kind of herniation is a Pitt pit?

Pitt pit refers to an oval or round lucency in the anterosuperior aspect of the femoral neck, just distal to the articular surface. It represents a herniation of synovium or soft tissues into the bone through a cortical defect, hence the alternate name synovial herniation pit.

How big is a Pitt pit in the femoral neck?

Pitt pit. Pitt pit refers to an oval or round lucency in the anterosuperior aspect of the femoral neck, just distal to the articular surface. It represents a herniation of synovium or soft tissues into the bone through a cortical defect, hence the alternate name synovial herniation pit. They are usually around 5 mm in diameter…

What’s the average size of a Pitt pit?

They are usually around 5 mm in diameter but can be anywhere between 3 mm and 15 mm. They are most often an incidental finding and of no clinical significance. There is debate about the exact etiology of herniation pits.
