Résumé
One of the simplest values that can be determined from the skeleton is sex; the accuracy is greater if essentialparts are intact. Discriminant functional analysis is the most popular statistical method implored in sexdetermination and this has encouraged the accurate assessment of anthropometric data. This study was carriedout to evaluate the sex-discriminatory characteristics of the clavicle of Nigerian origin. 45 clavicles (comprisingof 25 males and 20 females) of both sides were macerated from dissected cadavers from the Anatomy Departmentsof the University of Port Harcourt Rivers State, Igbinedion University Okada, Ambrose Ali University Ekpoma bothin Edo State and Nnamdi Azikiwe University Enugu State. Clavicles with signs of deformity and/or fracture wereexcluded. Parameters obtained from the clavicle included; length, weight mid-shaft circumference, robustnessindex, angles, and volume. The measurements obtained were subjected to SPSS (IBM version 23.0, Armonk, USA)paired sample t-test and Pearson’s correlation analysis to evaluate side difference and level of correlatesrespectively while Discriminant Function Analysis (DFA) was used to evaluate the accuracy of the parameters inestimating sex. Confidence level was set at 95%, and P-value <0.05 was taken to be significant. The result showedhigh sex differences in the measurement (P<0.01) as well as sex-differentiated correlation in the left and rightclavicular measurement (r2; 79 – 98%; P<0.01), The parameters of the right and left clavicle were highly significantwith positive correlation at varying degree for total population studied. The extent of correlation (80-99%)between the L & R clavicular measurements informed the need for side-specific DFA. The R & L clavicles producedcentroid values of 1.522 and 1.290 for males and –2.537 and -2.150 for females respectively. The accuracy inpredicting group membership using the right clavicular parameters was 91.5% while the left was 87.0%, with abetter prediction for females. The estimation of sex from the clavicle of Nigerian origin is at least 87% possibleusing the studied clavicular characteristics.
