Abstract

SILVA, J. G et al. High Incidence of Complete Ossification of the Superior Transverse Scapular Ligament in Brazilians and its Clinical Implications. Int. J. Morphol. [online]. 2007, vol.25, n.4, pp.855-859. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022007000400028.

The aim of this study was to verify the prevalence of the ossified superior transverse scapular ligament (STSL) on dry bones of scapulae. 221 dry bones were analyzed, (111 rights and 110 lefts), proceeding from Rio de Janeiro and of Santa Catarina, Brazil. As exclusion criterion, were not analyzed bones of children or damaged. For the quantitative analysis of the data, the software Graphad Instat was used. Fisher exact test was used considering the p ≤ 0,05 as significant. After analysis of the scapulae, 30,76% (68/ 221) presented the ossified STSL (p ≤ 0,0001) of which, 52,94% (36/68) were ossified on the right side and 47,05% (32/68) on the left one. The 153 scapulae that did not present the ossified STSL, it was observed in 19,6 % (30/153) of these bones, the superior edge varying in the transverse plan, increasing superior angulation and, modified the width and depth of the scapular incisure. This anatomical curiosity should be kept in mind by clinicians that approaches painful syndrome of the shoulder, as well as, this anatomical curiosity should be kept in mind by students that may manipulate this anatomical area
