M25.35: Other instability of joint Pelvic region and thigh

You have reduced stability in your hip or a joint in your pelvis.

The pelvis is made up of different bones. There are 3 bones on each side which each merge to form one large pelvic bone. A joint connects these two large pelvic bones to the sacrum at the back of the body. The sacrum is part of the lower spine. The two pelvic bones plus the sacrum form a bony pelvic ring or girdle. In front, the two pelvic bones are tightly joined to one another by ligaments and cartilage fiber. The hip joints are outside, to the side of the pelvis. They connect the pelvis to the thighbones. The hip joints enable the legs to be moved in different directions.

Joints are held together by ligaments and a tight capsule made up of connective tissue. The muscles around the joint and the bones involved in the joint are important for the joint’s stability.

Joints may be less stable if they are overextended. The capsule or the ligaments in the joint can get damaged when this happens. Disorders or injuries can also make joints less stable. When the affected joints are subjected to loads, they can feel unsteady. May then be less than usual.
