The complex process of bone regeneration is influenced by factors such as inflammatory responses, tissue interactions, and progenitor cells. Currently, multiple traumas can interfere with fracture healing, causing the prolonging or failure of healing. In these cases, bone grafting is the most effective treatment. However, there are several drawbacks, such as morbidity at the donor site and availability of suitable materials. Advantages have been provided in this field by a variety of stem cell types. Adipose-derived stem cells (ASCs) show promise. In the radiological examination of this study, it was confirmed that the C/S group showed faster regeneration than the other groups, and Micro-CT also showed that the degree of bone formation in the defect area was highest in the C/S group. Compared to the control group, the change in cortical bone area in the defect area decreased in the sham group (0.874), while it slightly increased in the C/S group (1.027). An increase in relative vascularity indicates a decrease in overall bone density, but a weak depression filled with fibrous tissue was observed outside the compact bone. It was confirmed that newly formed cortical bone showed a slight difference in bone density compared to surrounding normal bone tissue due to increased distribution of cortical bone. In this study, we investigated the effect of bone regeneration by ADMSCs measured by radiation and pathological effects. These data can ultimately be applied to humans with important clinical applications in various bone diseases, regenerative, and early stages of formative differentiation.

Shins are one of the most vulnerable bones in human body. Shin guards are evaluated by their effectiveness in reducing the force applied to the bone. In this study, a structural modified mechanical lumped model of the shin guard was developed to provide maximum force distribution using physical parameter change modification technique and genetic algorithm.

Objective: To determine which parameters, including femur morphology, proximal femur bone mineral density, or patient characteristics, are associated with bisphosphonate-related atypical femur fractures (AFFs) and to investigate the relationships between AFF location and these parameters.
Materials And Methods: Sixteen females with a history of bisphosphonate use who presented with AFFs and 38 females without AFFs, even those with long-term bisphosphonate use of > 5 years, were compared. Patient characteristics; physique, gait ability, and history of pain and medication, were recorded.

Purpose: This study aims to investigate the risk factors for postoperative complications following Femoral Neck System (FNS) fixation in young patients with femoral neck fractures (FNFs).
Methods: We retrospective analyzed 133 patients with FNFs who underwent FNS fixation between May 2021 and October 2023. Potential risk factors that may affect the results included age, gender, body mass index (BMI), Pauwels classification, Garden classification, fracture anatomical classification, reduction method, reduction quality, coronal plane position of the FNS bolt.

Background: Fibrous dysplasia/McCune-Albright syndrome (FD/MAS) is a genetic disorder, marked by bone lesions, often affecting the craniofacial skeleton. Pain is a prevalent yet heterogeneous symptom reported by patients with craniofacial FD. Effective treatments are currently lacking, posing a significant clinical challenge to patient care.
