Study Notes
Femur Anatomy
- Head of Femur: Rounded proximal end that articulates with the acetabulum of the pelvis, forming the hip joint.
- Neck of Femur: Narrow section connecting the head to the shaft, commonly fractured in hip injuries.
- Fovea Capitis: Small depression on the head of the femur where the ligamentum teres attaches, aiding stability in the hip joint.
- Greater Trochanter: Large, prominent projection on the femur's lateral side. Serves as an attachment point for several hip muscles, including the gluteus medius.
- Lesser Trochanter: Smaller projection on the femur's medial side, providing an attachment point for the iliopsoas muscle, important for hip flexion.
- Intertrochanteric Crest: Bony ridge between the greater and lesser trochanters on the posterior side, important for muscle attachment.
- Intertrochanteric Line: Smooth line on the anterior femur between the greater and lesser trochanters, serves as an attachment site for muscles and ligaments.
- Gluteal Tuberosity: Roughened area on the posterior femur for the attachment of the gluteus maximus muscle, contributing to hip extension.
- Linea Aspera: Prominent longitudinal ridge on the posterior aspect of the femoral shaft that serves as an attachment for various muscles.
- Medial Supracondylar Line: Ridge extending from the linea aspera to the medial condyle, providing muscle attachment and structural support.
- Lateral Supracondylar Line: Similar to the medial line but located on the femur's lateral side, aiding in muscle attachment.
- Lateral Condyle: Distal end of the femur on the lateral side, articulates with the fibula and provides stability to the knee joint.
- Intercondylar Notch: Deep notch between the lateral and medial condyles, accommodating ligaments such as the anterior and posterior cruciate ligaments.
- Medial Condyle: Distal end of the femur on the medial side, larger than the lateral condyle, and helps in weight-bearing.
- Adductor Tubercle: Bony prominence on the medial epicondyle for the attachment of the adductor magnus muscle.
- Lateral Epicondyle: Bony projection on the lateral side of the femur just above the lateral condyle, serving as a muscle and ligament attachment point.
- Medial Epicondyle: Located above the medial condyle, serves a similar function as the lateral epicondyle for muscle attachment.
- Patellar Surface: Smooth anterior surface where the patella (kneecap) articulates with the femur, facilitating knee movement.
