Normal Hip X-Ray Pathologic Fracture Hip X-Ray

The hip joint is a complex structure that involves the articulation of three bones - the pelvis, femur, and acetabulum. It is a ball-and-socket joint that allows for a wide range of movements, including flexion, extension, adduction, abduction, internal rotation, and external rotation.

The zona orbicularis, a set of internal circular fibers, forms a collar around the femoral neck and blends with pubofemoral and ischiofemoral ligaments. The joint capsule surrounds the hip joint, attaching to the margins of the labrum and the transverse ligament on the acetabulum.

The femoral head is attached to the body of the femur via the neck, which holds it at an angle. The central non-articular part of the acetabulum contains the Haversian fat pad, also known as the pulvinar. This notch is traversed by the transverse ligament.

The actual hyaline articular cartilage-covered area (lunate surface) is C-shaped and forms an incomplete ring due to the acetabular notch. The acetabulum covers nearly half of the femoral head, increasing the depth of the joint and providing stability but reducing movement.

In comparison to other joints such as the shoulder joint, the hip joint has a higher degree of mobility due to its ball-and-socket structure. However, it also provides greater stability due to the deeper socket and increased contact area.

The acetabulum is formed by the three bones of the pelvis - the ischium, ilium, and pubis. The triradiate cartilage, which is usually fused by age 14-16, separates these bones.

Innervation of the hip joint includes branches of the femoral, obturator, and superior gluteal nerves, as well as the nerve to quadratus femoris. Blood supply comes from branches of the medial and lateral circumflex femoral arteries, superior and inferior gluteal arteries, and obturator arteries.

The ligaments surrounding the hip joint include ischiofemoral, iliofemoral, pubofemoral, and transverse acetabular ligaments, as well as the ligamentum teres. These ligaments provide stability to the joint and help maintain proper alignment.

Pathologic fractures of the hip can occur due to various factors such as osteoporosis, cancer, or trauma. X-rays are often used to diagnose these fractures, which can be classified into different types based on their location and severity.

In conclusion, the normal hip x-ray pathologic fracture hip x-ray is a complex structure that involves the articulation of three bones - the pelvis, femur, and acetabulum. Understanding the anatomy and function of this joint is essential for diagnosing and treating pathologic fractures.
