It is the sacrum.
The femur articulates with the coxal bone at the hip joint. This joint is a ball-and-socket joint, allowing for a wide range of movement in the hip. The femur head fits into the acetabulum of the coxal bone.
Ilium Ischium Pubis The hip bone, is formed by the fusion of the ilium, the ischium, and the pubis, which occurs by the end of the teenage years.
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 femur articulates with the medial and lateral condyles of the tibia. The femur is the bone commonly known as the thigh bone.
The largest coxal bone is the ilium. It is one of the three bones that make up the hip bone, along with the ischium and pubis. The ilium is located superiorly and laterally, forming the largest portion of the hip bone.

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 lower limb attaches at the hip region, where the femur (thigh bone) articulates with the pelvic bone to form the hip joint.
The coxal bone is part of the hip joint.The longest bone in the body is the femur, thigh bone, which is a ball and socket joint with the hip joint or coxal bone.
The sacrum articulates with the hip bones of the pelvis.
The femur articulates with the medial and lateral condyles of the tibia. The femur is the bone commonly known as the thigh bone.
The largest coxal bone is the ilium. It is one of the three bones that make up the hip bone, along with the ischium and pubis. The ilium is located superiorly and laterally, forming the largest portion of the hip bone.
The hip bones protect the reproductive organs, the urinary organs, and provide partial protection for the intestines.the hip bone protects our internal organs
