The relationship between primate distal fibula trabecular architecture and arboreality, phylogeny and size.

Department of Biology, Università di Pisa, Pisa, Italy.
The fibula, despite being traditionally overlooked compared to the femur and the tibia, has recently received attention in primate functional morphology due to its correlation with the degree of arboreality (DOA). Highlighting further fibular features that are associated with arboreal habits would be key to improving palaeobiological inferences in fossil specimens. Here we present the first investigation on the trabecular bone structure of the primate fibula, focusing on the distal epiphysis, across a vast array of species.

Bone defects are difficult to treat clinically and most often require bone grafting for repair. However, the source of autograft bone is limited, and allograft bone carries the risk of disease transmission and immune rejection. As tissue engineering technology advances, bone replacement materials are playing an increasingly important role in the treatment of bone defects.

Background: Pediatric femoral neck fractures (PFNF) are rare but associated with a high rate of serious complications such as avascular femoral head necrosis (AVN). Major risk factors and prognostic tools for an AVN are still unclear. As AVN is a devastating complication, this study aims to evaluate the predictors for AVN following a PFNF.

Department of Neurosurgery, Damascus Hospital, Damascus, Syria; Faculty Of Medicine, Al-fourat university, Deir ez-Zor, Syria.
Introduction And Clinical Importance: Giant cell tumor (GCT) is a rare benign bone tumor that usually affects skeletally adult people. While it usually appears in the epiphyseal parts of long bones, it is very rare in the spine, particularly the thoracic spine, especially in pediatric patients.
Case Presentation: An 11-year-old female presented with progressive lower extremity weakness, accompanied by localized back pain and urinary urgency, diagnosed with GCT in the thoracic spine.

Background: Slipped Capital Femoral Epiphysis (SCFE) is a prevalent pediatric orthopedic condition. Treatment options range from in situ pinning to various osteotomies, with the Modified Dunn procedure gaining significant attention over the past two decades. However, the suitability of this procedure for different SCFE subtypes and the risk of avascular necrosis (AVN), particularly in moderate and severe cases, remains controversial.
