Features of the Femur

What are the three features on the head

Fovea Capitis
Greater Trochanter
lesser Trochanter

Post features of the shaft

Spiral line
Linea Aspera
Supracondylar lines
Gluteal Tuberosity
Popliteal surface

Distal features of shaft

Lateral & Medial condyle
Intercondylar fossa
Patellar surface
Epicondyles
Adductor tubercule
Supracondylar ridges

What are the intracapsular ligaments of the hip

Transverse acetabular lig
Ligamentum teres

Attachments & Function of the Iliofemoral - extracapsular ligament

ASIS to intertrochanteric line
Limits hyperextension

Attachments & Function of the Pubofemoral - extracapsular ligament

Obturator crest then blends with iliofemoral
Limits hyperextension & abduction

Attachments & Function of the Ischiofemoral - extracapsular ligament

From ischial part of acetabulum into the greater trochanter.
Restricts internal rotation

Describe the blood supply to the proximal femur

Medial and lateral circumflex branch off from profunda femoris - wrap around GT and neck of femur.
Acetabular branch from obturator artery, goes through ligamnetum teres.

Features of the Acetabulum

Lunate surface covered in hyaline cartilage
Acetabular fossa - covered in fat
Acetabular notch - bridged by transverse acetebular lig.

What is the angle of inclination and what are its normal ranges in newborn and adults

The angle btwn shaft and axis of the neck
Newborn = 150 degrees
Adults = 125 degrees

What is torsion

The degree of rotation of the neck in relation to shaft of femur
