What is synovial herniation pit?

What is synovial herniation 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 are herniation pits?

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 is a symptomatic synovial herniation pit?

Symptomatic synovial herniation pit—MRI appearances pre and post treatment. They have a thin sclerotic rim and represent benign bone pits that are felt to be a result of mechanical forces causing herniation of soft tissue and synovium through a defect in the bone. They are usually a unilateral incidental finding and rarely present with hip pain.

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.

Where are the herniation pits located in the neck?

Herniation pits or “Pitt’s pits” are small, well-delineated, lucent oval or sometimes lobulated and predominantly incidental lesions, found within the proximal superior quadrant of the femoral neck. Originally they were felt to result from mechanical forces causing herniation of soft tissue and synovium through a defect in the bone.

Are there any surgical interventions for synovial pits?

Synovial pits may have atypical clinical and radiological course, and this can raise concerns especially with symptomatic hip that may encourage surgical interventions. However, due to benign course of these lesions, we do not recommend any surgical intervention for such lesions. Synovial herniation pits, herniation pits, cortical defect
