bony landmarks of the hips

New Section

This section provides an overview of the hipbone and its different components.

Hipbone Structure

• The hipbone is formed by the fusion of three bones: the ischium, pubic bone, and ilium.

• The border between these three bones can be marked off with tape or by visually dividing it in half.

• The bottom half is the ischium, followed by the pubic bone, and then the ilium.

• The ilium has several notable features such as the iliac crest, iliac fossa, gluteal surface, and four spines (anterior superior iliac spine, anterior inferior iliac spine, posterior superior iliac spine, posterior inferior iliac spine).

• Following along the iliac crest leads to the posterior superior and posterior inferior iliac spines.

• The greater sciatic notch and lesser sciatic notch are also visible.

New Section

This section focuses on specific features of the ileum.

Features of Ileum

• The ileum has an arcuate line that becomes more visible when two arcuate lines come together to form the pelvic brim.

• Other notable features include the acetabulum.

New Section

This section explores details about the ischium.

Ischium Details

• The ischium forms the bottom portion of the hipbone and corresponds to what we sit on.

• It includes features such as the ischial tuberosity (roughened bump), ischial ramus (bottom half of arm), and ischial body (whole piece).

• From a different angle, we can observe the acetabulum.

New Section

This section delves into the pubic bone and its different components.

Pubic Bone Components

• The pubic bone has two parts: the ischial ramus (upper half) and the inferior pubic ramus (lower half).

• The entire structure of the pubic bone is referred to as the pubic crust.

• The bump at the edge of the pubic crust is called the pubic tubercle.

• The obturator foramen, a large hole, can also be observed.

New Section

This section discusses additional details about the pubic bone and its distinguishing features between male and female pelvises.

Pubic Symphysis and Sub Pubic Angle

• The point where the two pubic bones come together is known as the pubic symphysis.

• Below the pubic symphysis, there is a shape called the sub-pubic angle or pubic arch.

• In males, this angle resembles an "A" shape, while in females, it is broader and shaped like an upside-down "V".
