The femur, or thigh bone, is the longest, heaviest, and strongest bone in the body. The proximal end of the femur consists of a rounded head and the neck of the femur is a constricted region distal to the head. The body (shaft) of the femur angles medially. The greater trochanter and lesser trochanter are projections that serve as points of attachment for the tendons of some of the thigh and buttock muscles. The lesser trochanter is inferior and medial to the greater trochanter. A ridge called the intertrochanteric crest appears between the posterior surfaces of the greater trochanter and lesser trochanter. Inferior to the intertrochanteric crest on the posterior surface of the body of the femur is a vertical ridge called the gluteal tuberosity. It blends into another vertical ridge called the linea aspera. The expanded distal end of the femur includes the medial condyle and the lateral condyle. These articulate with the medial and lateral condyles of the tibia. Superior to the condyles are the medial epicondyle and the lateral epicondyle, to which ligaments of the knee joint attach. A depressed area between the condyles on the posterior surface is called the intercondylar fossa.

The hip (coxal) bones unite anteriorly with each other to form a joint called the _____ _______. They articulate posteriorly with the _____.
