The proper description of former populations is one of the most difficult tasks in anthropology. Archaeological material is often limited due to fragmented and sometimes poorly preserved bone material resulting in incomplete data. Published skeletal raw data are available from the past, but much of this data is either unavailable or not used for scientific studies. The authors seek to elicit more information about prehistoric times by using this dataset to introduce a new method. The purpose is to provide an approach to reconstruct a former population in respect to robusticity and health status. For this in the pilot study the Body Mass Index (BMI) and Frame Index (FI) of early medieval South-West Germany have been analysed. The FI, in contrast to the BMI, has not yet been used for robusticity analysis utilizing only skeletal remains. As far as we know, this is the first time that the FI has been calculated using archaeological material. Due to unknown soft-tissue thickness we introduce the Osseous Frame Index (OFI). The measured OFI reveals new insights in (pre-)historic populations and allows comparisons with modern reference samples. Our OFI calculations are relatively similar to modern calculations. Males have a higher robusticity than females, slightly increasing during life-time compared to females. These calculations provide a better historical understanding of human body composition.

Dietary preferences of extant reptiles can be directly observed, whereas diet reconstruction of extinct species typically relies on morphological or dental features. More specific information about the ingested diet is contained in the chemistry of hard tissues. Stable isotopes of calcium and strontium show systematic fractionations between diet and skeletal bioapatite, which is applied for diet and trophic-level reconstructions of extant and extinct vertebrate species.

Objective: This study aims to perform a meta-analysis that integrates multiple literature sources to evaluate the clinical efficacy of oblique lumbar interbody fusion (OLIF) versus minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for treating lumbar degenerative diseases (LDD).
Methods: A systematic search was conducted across various databases, including CNKI, VIP, WANFANG DATA, SinoMed, PubMed, Cochrane Library, Embase, and Web of Science, for clinical comparative studies on OLIF and MIS-TLIF for treating LDD, covering the time frame from the inception of the databases to September 2024. Following PRISMA guidelines, studies were screened, assessed, and data were extracted rigorously.

Mechanical unloading causes bone loss, but it remains unclear whether disuse-induced changes to bone microstructure are permanent or can be recovered upon reloading. We examined bone loss and recovery in 17 astronauts using time-lapsed high-resolution peripheral quantitative computed tomography and biochemical markers to determine whether disuse-induced changes are permanent. During 6 months in microgravity, resorption was threefold higher than formation.

DNA identification of human skeletal remains play a valuable role in the forensic field, especially in missing persons and mass disasters investigation. Hard tissues, such as bones and teeth, represent a very common kind of samples analyzed in forensic laboratories because often they are the only biological materials remaining. However, the major limitation in using these compact samples rely on time consuming and labor-intensive treatment of grinding them into powder before proceeding with the conventional DNA purification and extraction step.

Background: Temporary ankle-spanning circular fixation aims to provide osseous stability while (1) allowing access to and recovery of the traumatized soft-tissue envelope and (2) facilitating safe, comfortable, and clinically relevant cross-sectional imaging for surgical planning. It is most commonly utilized in a "span-scan-plan" treatment strategy in cases of peri-articular fractures around the ankle. Conventional monolateral fixators are prone to morbidity at the half-pin sites in the foot and variation in construct stability.
