The need to perform triple osteotomies of the pelvis passing very close to the articular surface leads to the isolation of bony fragments whose vascularisation may be precarious. To assess the risks of such surgery, we undertook an anatomic study of the vascularisation of the acetabulum in the fetus. 53 specimens were injected to study the vessels to the acetabulum and their distribution within the osteocartilaginous specimen. The acetabular a., a branch of the obturator a., gives a central pedicle distributed to the acetabular fossa, the triradiate cartilage and ending in the three primary bony components. The superior gluteal, inferior gluteal, internal pudendal and obturator aa. form a periacetabular vascular circle. The abundant vascularity of the acetabulum makes massive necrosis improbable in the child. However, there is a zone of precarious anastomosis at the anterior portion of the acetabulum.

Background: Gravid females with pelvic fractures are rarely encountered by the orthopaedic trauma surgeon. The initial injury can be detrimental to the pregnant patient, but an unnecessary "second hit" from surgery could also contribute to the outcome of the fetus. Understanding the surgical risks for this unique patient population requires knowledge about the negative effects of anesthesia, surgical exposures, and radiation.

Article Synopsis
- The DYNC2H1 gene is linked to short-rib polydactyly syndrome (SRPS) and other skeletal ciliopathies, with two unique cases highlighting distinct phenotypes caused by splicing variants.
- The first case involved a 14-week-old fetus with severe malformations and two compound heterozygous variants that were initially uncertain but later deemed likely pathogenic after further testing.
- The second case presented an 11-year-old boy with various physical abnormalities and identified variants in DYNC2H1, underscoring the gene's role in conditions like SRPS and orofaciodigital syndrome, enhancing understanding of splicing variants' impacts.

Background: Türkiye is a country in the world ranking in terms of sheep breeding. Hamdani crossbred sheep breed is one of the sheep breeds that can adapt to the difficult conditions in our country. In addition, the sentence may be corrected as 'Especially in the southeastern part of the Türkiye, crossbreeding is preferred by breeders to increase the yield characteristics of sheep'.

Childbirth is a complex physiological process in which a foetal neuromusculoskeletal model is of great importance to develop realistic delivery simulations and associated complication analyses. However, the estimation of hip joint centre (HJC) in foetuses remains a challenging issue. Thus, this paper aims to propose and evaluate a new approach to locate the HJC in foetuses.
