Anatomical variations of the cubital tunnel may contribute towards cubital tunnel syndrome (CuTS), however, these are not well described. The aim was to compare the range of variations and dimensions of the cubital tunnel and the UN between sexes and sides of the body.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Sixty elbows from 30 embalmed bodies (17 males and 13 females) were dissected. The prevalence of the cubital tunnel retinaculum (CuTR) or <jats:italic>anconeus epitrochlearis<\/jats:italic> (AE) forming the roof of the tunnel was determined. The length, width, thickness, and diameter of the cubital tunnel and its roof were measured.

The tunnel was 32.1\u2009\u00b1\u20094.8\u00a0mm long, 23.4\u2009\u00b1\u200914.2\u00a0mm wide, 0.18\u2009\u00b1\u2009(0.22\u20130.14) mm thick, and the median diameter was 7.9\u2009\u00b1\u2009(9.0\u20137.1) mm, while the median diameter of the UN was 1.6\u2009\u00b1\u2009(1.8\u20131.3) mm. The AE was thicker than the CuTR (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) and the UN was larger in elbows with the AE present (<jats:italic>p<\/jats:italic>\u2009=\u20090.002).
