Study Notes
Sacroiliac Joint
- The auricular surface of the ilium articulates with the auricular surface of the sacrum.
- This articulation forms the sacroiliac joint, crucial for stability in the pelvis.
Coxal Joint
- The acetabulum of the coxal bone connects with the head of the femur.
- This forms the coxal joint, which allows for a wide range of motion in the hip.
Patellofemoral Joint
- The patellar surface of the femur interfaces with the patella.
- This articulation is vital for knee extension and stability.
Tibiofemoral Joint
- The medial and lateral condyles of the femur articulate with the tibia.
- This joint plays a fundamental role in weight-bearing and movement.
Fibula and Tibia Connections
- The head of the fibula articulates with the tibia.
- The lateral condyle of the tibia connects with both the lateral condyle of the femur and the head of the fibula.
Distal Articulations
- The lateral malleolus of the fibula connects with the distal tibia.
- The lateral portion of the distal tibia articulates with the lateral malleolus, which contributes to ankle stability.
