Pelvic Malalignment
Innominate | A. Posterior rotation | B. Anterior Rotation |
---|---|---|
Iliac Crest | Elevated โ | Elevated โ |
ASIS | Elevated โ | Depressed โ |
PSIS | Depressed โ | Elevated โ |
scapula | Depressed โ | Elevated โ |
leg | Longer โ | Shorter โ |
10-15mm lift | Increased crest difference โ | Reduced crest difference โ |
Spinal curvature | C type scoliosis | S type scoliosis |
C0-C1 function | Symmetric rotation in flexion | Restricted rotation in flexion |
All changes are in reference the ipsilateral side.
Rising of the crest upon anterior SI rotation is paradoxical, and its explanation cannot be reduced to a two-dimensional model.
Schambergerโs (2013) rule of the five Ls, which relates to the side of the anteriorly rotated innominate: โLeg Lengthens Lying, Landmarks Lowerโ (supine vs long sitting)
Those patients showing pelvic asymmetry caused by dysfunction of the SI joint received one of two treatment options: (1) high-velocity and low-amplitude thrust technique applied through the ankle on the side of the dysfunctional SI joint or (2) restoration of symmetry by the selfembracing muscle energy technique. In this procedure, a patient resists thigh extension, alternating on both sides, to produce a corrective rotational force on the pelvis. Both methods have been described in detail elsewhere.3,12 The estimation of asymmetry as described was repeated after the corrective treatment.
