“…However, no significant delayed DFE ossification with respect to age was observed in the extant sample between the group of individuals who died before 2 postpartum months and the group of those who survived, neither between the group with diverse severe developmental anomalies nor those with normal health status. Thus, the observation in the extant sample does not support the hypothesis that delayed epiphysis maturation in the knee is a sufficiently sensitive indicator to be used as a nonspecific morbidity indicator for this age group in past populations, unlike other osteological markers such as the supernumerary cervical rib (Partiot, 2018; Partiot et al, 2020) or fluctuating asymmetries (Partiot et al, 2021).…”

The distal epiphysis of the femur is classically reported as a marker of fetal maturity and is thus identified in a bioarcheological context as an indicator that an individual died at or around the time of birth; it thus provides crucial information in the creation of the biological profile and associated burial practices. The aim of the present study was to re‐evaluate this use by investigating an extant sample to assess (i) the age‐related frequencies of both distal femoral and proximal tibial epiphyses and (ii) the influence of factors such as sex, vitality, and morbidity on the maturation of both epiphyses. The study was conducted on medical CT scans acquired in utero and ex utero between 2008 and 2017 in the hospital of Marseille (France). The final sample included 248 individuals aged between 26 and 42 completed gestational weeks (GW). Based on the results obtained in this study, 11% of the individuals from the sample aged between 26 and 33 completed GW had already developed a distal femoral epiphysis, whereas individuals aged between 38 and 42 GW had already developed both femoral and tibial epiphyses. According to these observations and current obstetrical practice, this maturation indicator cannot therefore be considered a precise estimator of whether a fetus is at term or not in an archeological context. Similarly, no delayed ossification was found among individuals who did not survive to 42 GW, or among those with severe developmental abnormalities, which does not support the hypothesis that delayed epiphysis maturation of the distal femur may be a morbidity marker for this age group in past populations.

“…On peut donc avancer qu'une proportion, certes difficile à évaluer, des sujets décédés au cours de la période périnatale dans les populations anciennes ne sont pas porteurs d'anomalies majeures du développement ou de pathologies graves, et ne seraient pas à même d'être considérés comme "hors-normes". Plus spécifiquement, l'existence d'anomalies du développement a toutefois pu être discutée pour 27 individus appartenant à la collection de l'île de Saï, et ce en raison de la présence sur leur squelette de côtes surnuméraires cervicales, caractéristique anatomique associée à des mutations dans les gènes Hox et identifiée comme un critère de morbidité pour la classe d'âge périnatale (Partiot et al, 2020). Il pourrait cependant s'agir d'un cas relativement particulier, puisque des facteurs comme la nature insulaire de la population, l'existence de proximités génétiques, voire de phénomènes de consanguinité, auraient pu contribuer à augmenter le taux d'anomalies du développement (Partiot, 2018 ;Partiot et al, 2020).…”

Les asymétries directionnelles (expression préférentielle d'un caractère d'un côté plutôt que de l'autre) et les asymétries fluctuantes (écarts mineurs, aléatoires et indépendants par rapport à la symétrie bilatérale) font l'objet d'un nombre croissant d'analyses dans des corpus actuels de sujets décédés en période périnatale, du fait de leurs implications respectives dans les questions de latéralisation préférentielle et de stabilité du développement. Ces axes de recherche sont toutefois rarement investis dans cette classe d'âge et dans les populations du passé. Notre étude s'est ainsi donné pour objectif de rechercher la présence ou l'absence de ces deux types d'asymétries dans un corpus archéologique, via une approche exploratoire adaptant les protocoles existants aux spécificités de ce matériel ostéologique. Réalisée sur un corpus de 116 individus issus de trois collections (nécropole 8B-51, île de Saï, Soudan, Kerma classique ; cimetière de Blandy-les-Tours, Bassin parisien, X e -XII e siècles ; cimetière de Provins, Bassin parisien, XIII e -XVIII e siècles), cette étude apporte des éléments de réflexion quant à la faisabilité méthodologique de ces analyses sur os sec, en permettant d'identifier des variables exprimant ces asymétries. Ces résultats préliminaires visent à engager la discussion quant à l'emploi de ces marqueurs biologiques pour les analyses ostéobiographiques de sujets immatures issus de populations du passé, notamment en tant qu'estimateur des perturbations du développement.

“…However, they are becoming more well-known in the medical community due to their important role in the pathophysiology of various arterial, venous, and neurological pathologies, including thoracic outlet syndrome (TOS) [7,24]. Cervical ribs can either end freely in the soft tissues of the neck or articulate with the rst rib posterior to the scalene tubercle [21]. Ethnic and regional variations in the prevalence of cervical ribs have been reported.…”

Prevalence of cervical ribs and elongated transverse processes in Omani population: a computed tomography-based study

IntroductionCervical ribs are the supernumerary ribs that usually arise from the seventh cervical vertebra. Ethnic and geographical variations in the prevalence of cervical ribs and elongated transverse processes have been reported. We aimed to study the prevalence of cervical ribs and elongated transverse processes in Omani subjects using computed tomography (CT). MethodsA total of 1165 consecutive patient CT scans of the cervical spine who had visited the tertiary care hospital from January 2016 to December 2020 were included in the study. The CT scans were screened for the presence of cervical ribs and elongated C7 transverse processes. The Chi-square test was used to determine the gender in uence. ResultsCervical ribs were identi ed in 0.94% of patients with a female dominance (p<0.05). The majority of the cervical ribs were unilateral (54%). The elongated C7 transverse process was identi ed in 18.45% of patients, with a male to female ratio of 1.36:1. The presence of an elongated C7 transverse process was strongly associated with gender (p< 0.001). ConclusionThe prevalence of cervical ribs in Omani subjects is close to that of generally accepted prevalence worldwide. However, the elongated C7 transverse process prevalence is comparatively high and close to the prevalence of the Saudi population.
