What is the pelvis?
The pelvis is a basin-shaped structure that supports the spinal column, protects the abdominal organs, and provides the structure for the hip joints. It contains the following:
-
Sacrum. A spade-shaped bone that is formed by the fusion of 5 originally separate sacral vertebrae.
-
Coccyx (tailbone). Formed by the fusion of 4 originally separated coccygeal bones.
-
Three hip bones. These are:
-
Ilium. The broad, flaring portion of the hip bone (the crest of the pelvis).
-
Pubis. The lower, posterior part of the hip bone.
-
Ischium. One of the bones that helps form the hip.

Common pelvis problems
Two of the more common pelvic problems are:
-
Pelvic fractures. A pelvic fracture is a break in one or more of the pelvic bones. It is the result of major force. Some pelvic fractures can heal on their own. But unstable or high-energy fractures need surgery.
Most pelvic fractures are caused by direct hits or by a hit through the thighbone (femur). They often occur due to motor vehicle accidents, especially motorcycle accidents.
-
Osteitis pubis. This is an inflammation of the pubic symphysis, the slightly moveable joint of the front of the pelvis. It causes pain in the groin and soreness over the front of the pelvis. This condition is often due to repeated pelvis stress, such as kicking the ball in soccer. Rest often heals the condition.

Low Back Pain
Everyone has experienced low back pain at one time or another. Most people can recover from low back pain with home treatment, such as changes in activity, weight loss, quitting smoking, and other steps. Sometimes medicine or surgery is needed.
Foot Pain and Problems
Foot pain is often caused by incorrect foot function. Shoes that don't fit well can make foot problems worse and, in some cases, cause them.
Shoulder Separation
When you have a shoulder separation injury, trauma damages the ligaments surrounding your acromioclavicular (AC) joint. This is where your collarbone (clavicle) meets your shoulder blade (scapula). If your injury is severe, part of your shoulder blade actually separates from your collarbone.
