HIP REGION:

HIP AND THIGH - BONES AND JOINTS:

Anatomy of the hip and thigh:

Pelvic girdle - structure and function:

Pelvis (pelvic girdle):

Supports and protects abdominal and pelvic organs.

Transmits forces from the head and trunk to the lower limbs.

Provides attachment sites for muscles and ligaments.

Composed of:

Two hip (innominate) bones (ilium, ischium, pubis).

Sacrum and coccyx (form a ring-like bony structure).

Articulations of the pelvis:

Key features:

Proximal femur (thigh bone):

Structural features:

Components of the proximal femur:

Small central depression on the femoral head.

Neck of femur:

Anatomical neck: epiphyseal line between the head and intertrochanteric line or crest.

Located at the junction of the shaft and proximal extremity.

Greater trochanter:

Lesser trochanter:

Intertrochanteric structures:

Connects the greater and lesser trochanters.

Intertrochanteric crest (posteriorly):

Acetabulofemoral joint (hip joint) components:

· Acetabular fossa:

o Ligaments of the hip joint:

. Appearance: inverted Y-shaped, the strongest and thickest ligament of the hip.

· Functions:

· Attachments:

Ischiofemoral ligament (ischiocapsular ligament):

· Functions:

○ Other hip ligaments:

· Bridges the acetabular notch.

Ligamentum teres femoris (ligamentum capitis femoris/Ligament of the head of the femur):

· Attachments:

HIP MUSCLES:

· Gluteal region muscles:

Forms the main bulk of the buttock region.

Additional bony features:

Impression for Iliotibial tract: attachment site for the iliotibial band.

Bony features of the patella:

Overview

This document provides a comprehensive overview of the anatomy of the hip region, including the pelvic girdle, bones, joints, and muscle groups involved. It discusses the structure and function of these components, as well as their relevance in clinical contexts such as childbirth and movement.

Key Points

1The pelvic girdle supports abdominal organs and transmits force to lower limbs
2The true pelvis is crucial for obstetric relevance and the birth canal
3Key bones include ilium, ischium, and pubis, each with distinct anatomical features
4Various ligaments contribute to hip joint stability and movement
5The document covers muscles of the hip, including functional roles and clinical notes on their implications.
