femurstamme

The femurstamme, also known as the femoral shaft, is the long, cylindrical main part of the femur, the thigh bone. It is the largest and strongest bone in the human body, extending from the lesser trochanter to the supracondylar ridge. The femurstamme is primarily composed of dense cortical bone, which provides structural integrity and protection for the marrow cavity within. This cavity contains yellow marrow in adults, which consists mainly of fat.

The femurstamme is triangular in cross-section, with three distinct surfaces: anterior, medial, and lateral. It also has three borders: anterior, medial, and lateral. The anterior surface is smooth and rounded, while the posterior surface features a prominent ridge called the linea aspera. This linea aspera serves as an attachment site for several powerful thigh muscles, including the adductors and vastus muscles.

The femurstamme plays a crucial role in locomotion, transmitting forces from the pelvis to the tibia and fibula during walking, running, and jumping. Its robust structure is essential for supporting body weight and enabling movement. Fractures of the femurstamme are serious injuries that typically require significant force to occur and often necessitate surgical intervention for proper healing.
