Biomechanics FLLD
Unleveling of the pelvis, clinically seen as a functional leg length discrepancy (difference), frequently results from abnormal foot mechanics (abnormal pronation) or abnormal dental mechanics (malocclusion).
Abnormal pronation (an inward, forward and downward rotation of the foot) results in an anterior rotation of the hips (Rothbart, 2006). The more anteriorly rotated hip is ipsilateral to the more pronated foot. Two of the most common causes of abnormal foot pronation is the Rothbarts Foot and the PreClinical Clubfoot Deformity.
The above animation demonstrates the link between an anteriorly (forwardly) rotated left hip and the resulting functionally short left leg:
- Anterior rotation of the left hip displaces the left acetabulum cephalad
- This results in the upward displacement of the left femur head
- Supine, the left leg appears shorter. The left PSIS is higher than the right PSIS.
- Standing, the left leg functions shorter (clinically observed as a lateral drift to the left as the patient walks)
