I have a friend who is a dwarf with a special condition called diastrophic dysplasia. She is bent forward at the hips and knees and can’t stand up straight. What causes this?
Diastrophic dysplasia is a condition that affects the bones. It causes curving or bowing of long bones such as the femur in the thigh. This shape of the bones causes the muscles to become short or contracted. The change in the shape of the bones and the shortening of muscles keeps the hips from extending. There are stretching programs to help keep the muscles from getting tighter. Often, the loss of motion is combined with joint pain, making these exercises difficult. Hip joint replacement is helpful when there is severe pain and difficulty walking or performing daily activities.
