An X-ray of the pelvis is a safe and painless test to visualise the hip bones, upper part of thigh bone (proximal femur), hip joint and the soft tissues (skin and muscles) surrounding it, using a small amount of radiation. The image is recorded on a special X-ray film. In this, dense structures such as the bones, appear white and soft body tissues, such as the skin and muscles appear darker.
This test helps to diagnose any fractures of the pelvic bones which includes the hip bone and upper part of thigh bone and to monitor the healing of the broken bone, after it has been set. It also helps to detect any infection, osteoporosis, deformities or abnormal growth of the bones of this region and diagnose any suspected arthritis, sacroiliitis, hip dislocations and ankylosing spondylitis.
