Figure 9.

Illustration showing the conventional standing position posture and center of gravity alignment (left), compared to posture assumed by X-linked hypophosphatemia individuals (right) to initiate the gait cycle, to achieve a vertical gaze during ambulation. The posture presents with diminished lumbar spine lordosis and posterior pelvic tilt assumed secondary to significant restriction of the cervical spine and forward flexed posture, structural spinal kyphosis, and spinal mineralizing enthesopathy.
