From Wikipedia: The hip bone, innominate bone or coxal bone is a large, flattened, irregularly shaped bone. It has one of the few ball and socket synovial joints in the body – the so called hip joint. It meets its fellow on the opposite side in the middle line in front, and together they form the sides and anterior wall of the pelvic cavity. Together with the sacrum and coccyx, it comprises the pelvis
OS INNOMINATUM The " os innominatum," so named by Galen, is made up of three bones, distinct in childhood, but united in the adult, and termed the "ilium," "ischium," and "pubes." Thus its constituents have received appropriate names, but the bone, consolidated, remains " nameless." Human osteology By Luther Holden 1899

Table 8.1 Summary of Joint Classes(DON’T NEED TO KNOW ALL DETAILS, BUT KNOW THREE BASIC TYPES OF JOINTS)
(c) Gomphosis (a) Suture (b) Syndesmosis Joint held together with very short, interconnecting fibers, and bone edges interlock. Found only in the skull. Joint held together by a ligament. Fibrous tissue can vary in length, but is longer than in sutures. “Peg in socket” fibrous joint. Periodontal ligament holds tooth in socket. Socket of alveolar process Suture line Fibula Tibia Root of tooth Dense fibrous connective tissue Ligament Periodontal ligament Figure 8.1 Fibrous joints. (DON’T NEED TO KNOW ALL DETAILS)
(a) Synchondroses Bones united by hyaline cartilage Sternum (manubrium) Epiphyseal plate (temporary hyaline cartilage joint) Joint between first rib and sternum (immovable) (b) Symphyses Bones united by fibrocartilage Body of vertebra Fibrocartilaginous intervertebral disc Hyaline cartilage Pubic symphysis Figure 8.2 Cartilaginous joints.
