The trochlea articulates primarily with the ulna, which is one of the two long bones in the forearm. This articulation occurs at the elbow joint, allowing for the hinge-like movement of the forearm relative to the upper arm. The trochlea is part of the humerus, which also articulates with other structures in the elbow joint.
The bone thst articulates with the tibia and fibula is the Talus bone.
The fourth metacarpal bone articulates with the fourth proximal phalanx in the hand.
The first cervical vertebra, called C1 or the atlas, articulates with the occipital bone.
the medial end articulates with the sternum and the distal end articulates with the humerus and scapula.

One side of the pubis articulates interiorly with the other side of the pubis, joining at the pubic symphysis. Posteriorly it articulates with the sacrum, the Acetabulum proximally articulates with Femur bone. So therefore there are three articulation points for the pelvic girdle.

The bone marking of the femur that articulates with the pelvic girdle is called the head of the femur.
