To examine the role of oblique-axis sacral torsion in the presence of true or apparent short leg.
Prospective blind trial of eighteen subjects.
A suburban chiropractic practice, a hospital and a university campus.
Of 33 subjects selected, 27 completed the study, 8 exhibited elimination criteria, and 1 X-ray was nondiagnostic.
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).
Oblique-axis sacral torsion may play a role in intrapelvic adaptation to anisomelia of the lower limb; further examination of this prospect is warranted.
探讨在真性或假性短腿情况下斜轴骶骨扭转的作用。
对18名受试者进行前瞻性盲法试验。
一家郊区整脊诊所、一家医院和一个大学校园。
在入选的33名受试者中，27名完成了研究，8名不符合入选标准，1份X线片无法做出诊断。
3×3列联表显示，在下肢长度不等（LLI）的受试者中，单侧骶骨突出具有统计学意义（p>.001）。短腿侧单侧骶骨突出的发生率也具有统计学意义（p>.05）。加权卡方检验证实了两者（α>.001）。
斜轴骶骨扭转可能在盆腔内对下肢不等长的适应性调节中起作用；有必要对这一前景进行进一步研究。
