Detailed explanation-1: -The thigh bone, or femur, is the large upper leg bone that connects the lower leg bones (knee joint) to the pelvic bone (hip joint).

Detailed explanation-2: -It angles outward toward the hip from the center of mass of the body. So a right femur angles toward the right, a left femur angles toward the left. Remember, right and left refer to the skeleton’s body, not the way you are looking at it!

Detailed explanation-3: -The femur or thigh bone is one of the longest bones in the human body. The upper part of the thigh bone consists of the femoral head, femoral neck, and greater and lesser trochanters. The head of the femur joins the pelvis (acetabulum) to form the hip joint.

Detailed explanation-4: -A femoral shaft fracture usually causes immediate, severe pain. You will not be able to put weight on the injured leg, and it may look deformed-shorter than the other leg and no longer straight.

Detailed explanation-5: -A broken femur is a serious injury that requires immediate medical care. Broken femurs are treated with surgery and physical therapy. It can take months for your broken femur to heal. You can break your femur by being in a car crash, falling or being shot.
