OBJECTIVE: To examine the role of oblique-axis sacral torsion in the presence of true or apparent short leg.
DESIGN: Prospective blind trial of eighteen subjects.
SETTING: A suburban chiropractic practice, a hospital and a university campus.
SUBJECTS: Of 33 subjects selected, 27 completed the study, 8 exhibited elimination criteria, and 1 X-ray was nondiagnostic.
MAIN RESULTS: 3 x 3 contingency table showed the presence of unilateral sacral prominence as statistically significant (p > .001) in subjects with LLI. The incidence of unilateral sacral prominence on the short leg side was also significant (p > .05). Weighted kappa confirmed both (alpha > .001).
CONCLUSIONS: Oblique-axis sacral torsion may play a role in intrapelvic adaptation to anisomelia of the lower limb; further examination of this prospect is warranted.
