“…The insert functioned as the pubic symphysis to account for the absence of soft tissue. Several studies have confirmed an average thickness of the pubic symphysis of 5 mm (Garagiola, Tarver, Gibson, Rogers, & Wass, 1989; Schoellner, Szöke, & Siegburg, 2001; Sequeira, 1986). The following measurements of the articulated pelvic girdle were performed according to the descriptions of Dauber and Feneis (2008) and Bräuer (1988): intercristal distance, transverse diameter of the pelvic inlet, transverse diameter of the pelvic outlet, right and left anteroposterior inlet diameter, distance between ischial spines, the left and right oblique diameter, right and left anatomic conjugate, anterior upper spinal breadth and interobturatum breadth.…”

The theory behind the formation and manifestation of pelvic scars, sometimes called 'scars of parturition', and particularly their potential use in determining parity history has been a debated issue among anthropologists for nearly 50 years. To date, the association between parity and scar formation still remains unclear. The present study tests the effects of sex, age, body size and pelvic dimensions on the morphological and metric features of dorsal pits, pubic tubercle and preauricular sulcus. A total of 296 skeletons (167 males, 129 females) from historical samples in Lithuania were examined. Beyond assessing the above traits of these pelvic scars, we determined sex, age at death and pelvis dimensions. Moreover, we reconstructed body height and body mass. A marked sexual dimorphism was recorded. Scar formation was significantly more common among females. With increasing age, scar formation increased or remain unchanged. Pelvic dimensions, body height and body mass showed a weak association with pelvic scars. Sex seems to be independently associated with scar formation. Our results suggest that although sex plays a dominant role in scar formation, caution should be exercised in interpreting scars as being due solely to parity alone. The term 'scars of parturition' should be avoided.

Fixateure externe zur Behandlung der intrapartalen Symphysensprengung

ZusammenfassungDie komplette intrapartale Symphysenruptur ist eine seltene, aber schwerwiegende Komplikation der natürlichen Geburt mit einer Inzidenz von 0,03–3 ‰. Kleine Partialrupturen mit geringen Dehiszenzen sind eine Domäne der konservativen Therapie mittels Beckenorthese. Bei größeren symphysären Dehiszenzen sollten eine operative Reposition und Fixierung erfolgen. Im Folgenden wird der Fall einer jungen zweitgebährenden Mutter mit kompletter Symphysensprengung und Dehiszenz von 39 mm beschrieben. Die operative Therapie mittels Anlage eines supraacetabulären Fixateur externe über einen Zeitraum von 12 Wochen lieferte ein gutes Ergebnis.

“…Most studies have been conducted postmortem, with only a few that used quantitative in vivo analyses (Alicioglu et al, 2008; Aydın et al, 2016; Bauman et al, 2011; Björklund et al, 1996; Schoellner et al, 2001; Weber et al, 1997; Wurdinger et al, 2002). These in‐vivo studies have mostly focused on symphyseal width in the context of obstetrics (which limits the analyses of male morphology), and on age‐at‐death estimation from the symphyseal faces.…”

Objectives When reconstructing fossil pelves, the articulation of the pelvic bones largely relies on subjective decisions by researchers. Different positionings at the pubic symphysis can affect the overall morphology of the pelvis and the subsequent biological interpretation associated with that individual or species. This study aims to reduce this subjectivity using quantitative models to predict pubic symphysis morphology. Methods We collected 3D landmarks and semilandmarks on the pubic symphysis and adjacent aspects on the CT scans of 103 adults. Using geometric morphometrics we, (1) quantified pubic symphysis morphology, (2) trained simple and two‐stage least‐squares linear regression models to predict pubic symphysis shape, and (3) assessed the shape variation in the sample. The model with the lowest prediction error was identified as the best model. Principal components analysis was used to explore the effects of each variable on shape and hypothetical shapes were generated from the model to illustrate these effects. Results The best model is a two‐stage least‐squares model that predicts pubic symphysis size at the first stage using additive effects of sex and age, then subsequently interacts pubic symphysis size with sex and age at the second stage to predict pubic symphysis shape. Other models with low prediction errors included variables reflecting pelvic size and breadth. Conclusion Linear regression modeling can be used to systematically predict pubic symphysis morphology. This method can be used in addition to other techniques to improve fossil reconstructions by more accurately estimating the morphology of this region of the pelvis.
