Recent advances in non-destructive techniques for imaging of cancellous bone have made possible true three-dimensional (3D) quantification of trabecular architecture. The architectural property can be measured from 3D reconstruction of cancellous bone specimens. Examples of such procedures are model-independent assessment of trabecular dimensions, 3D connectivity estimation, degree of anisotropy and structure type assessment. These new techniques would be utilized for the analysis of bone microstructure in various pathophysiological models.

Background: While there have been significant advancements in recent years, complications following fixation for femoral neck fractures remain a concern. This retrospective cohort study aimed to investigate the influence of polytrauma and additional fractures on the occurrence of complications in patients who underwent surgical fixation for femoral neck fractures. The study focused on analyzing patient demographics, comorbidities, fracture classifications, fixation methods, and the likelihood of experiencing post-operative complications, with a specific emphasis on the impact of polytrauma and additional fractures.

In this study, we aim to investigate the effects of sedentary behavior (SED) on bone health, as well as the potential favor effects of moderate to vigorous physical activity (MVPA) and periodic interruptions of SED. To simulate SED, we used small Plexiglas cages (20.

With the rise of bone tissue engineering (BET), 3D-printed HA/PCL scaffolds for bone defect repair have been extensively studied. However, little research has been conducted on the differences in osteogenic induction and regulation of macrophage (MPs) polarisation properties of HA/PCL scaffolds with different fibre orientations. Here, we applied 3D printing technology to prepare three sets of HA/PCL scaffolds with different fibre orientations (0-90, 0-90-135, and 0-90-45) to study the differences in physicochemical properties and to investigate the response effects of MPs and bone marrow mesenchymal stem cells (BMSCs) on scaffolds with different fibre orientations.

Objective: The purpose of this study was to quantify analgesic use following alveolar cleft bone grafting (ABG) utilizing a posterior iliac crest (PIC) donor site.
Design: This is a prospective cohort study of consecutive patients that underwent ABG with PIC in a 10 month period from November 2022 to September 2023.
Setting: Tertiary care free-standing pediatric hospital.

Osteoma is a rare benign tumor primarily affecting the craniofacial skeleton. Coronary osteomas in the coronoid process are uncommon and asymptomatic until they affect mandibular function. This report presents a case of coronoid osteoma with its diagnosis, treatment and surgical approach.
