the rib cage
headThe pedicle of the rib articulates with the transverse process of the thoracic vertebra.
transverse costal facets
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 clavicle. This bone is normally not consideredto be part of the shoulder an instead a part of the thorax, which is also true. The reason it is part of the shoulder is that it joint part of the scapula to form the soked of the glenohumeral joint.
