Osteology of the Femur, Tibia and Fibula Flashcards
Femoral neck angle
The angle between the shaft and neck.
120°-130°.
Anterior shaft of femur
- Relatively smooth surface
* Origin of the vastus intermedius
Medial shaft of femur
Between the linea aspera and medial border.
Origin of the vastus medialis.
Lateral shaft of the femur
Between the linea aspera and lateral border.
Origin of the vastus intermedius.
Pectineal line
From the lesser trochanter (medially) to the linea aspera.
Proximal posterior surface of femur.
• Proximal insertion of the adductor magnus.
Gluteal tuberosity
From the greater trochanter (laterally) to the linea aspera.
Proximal posterior surface of femur.
• Part of gluteus maximus insertion.
Linea aspera
Double line, posterior middle shaft of femur.
Medial and lateral supracondylar line
Distal posterior part of femur.
Popliteal surface
Triangular area on distal posterior surface.
No muscle attachments.
Intercondylar fossa/notch
Attachment of cruciate ligaments (intracapsular).
Between medial and lateral condyles on posterior surface.
Medial epicondyle of femur
Medial epicondyle attachment of medial collateral ligament (MCL).
Adductor tubercle
Adductor tubercle attachment of adductor magnus.
On medial epicondyle.
Lateral epicondyle
Lateral epicondyle is attachment site for lateral collateral ligament (LCL).
Medial condyle
Larger shape.
Thinner articular surface.
Normally covered in hyaline cartilage.
Lateral articular surface of tibia
Smaller than medial.
Provide surface area for lateral meniscus to attach.
Normally covered in hyaline cartilage.
