Summary
A hip joint acetabular cup protruded into the pelvis, displacing iliac vessels. An extraperitoneal approach enabled safe removal, preventing vascular injury during revision surgery.
Area of Science:
- Orthopedic Surgery
- Vascular Surgery
- Medical Imaging
Context:
- A rare complication of hip arthroplasty involves acetabular cup protrusion into the pelvis.
- This can lead to significant displacement of adjacent iliac vessels, posing a risk during revision surgery.
Purpose:
- To report a case of pelvic acetabular cup protrusion.
- To describe a surgical technique for safe removal of the displaced component and associated risk mitigation.
Summary:
- A case of complete pelvic protrusion of a hip joint acetabular cup is presented.
- Angiography revealed significant iliac vessel displacement by the acetabular cup.
- A separate extraperitoneal approach (Leitz) facilitated safe acetabular cup and prosthesis ball removal, followed by transgluteal stem removal.
Impact:
- Highlights the critical role of preoperative angiography in assessing vascular risk.
- Demonstrates the efficacy of the extraperitoneal approach for managing acetabular cup protrusion.
- Provides a valuable surgical strategy for preventing iatrogenic vascular injury in complex hip revision cases.

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...
01:23Knee 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...
