Purpose: This retrospective study aimed to evaluate bone remodeling of temporo-mandibular joints (TMJ) using computed tomography (CT) before and after condylectomy for condylar hyperplasia.
Material And Method: TMJ bone remodeling was studied by comparing the pre and postoperative CT scan of ten patients. Qualitative evaluation was performed by two-dimensional analysis. Three-dimensional analysis superimpositions were done after digital condylar units isolation. Condylar volume modifications were measured and compared on both sides. Lastly, before and after surgery, we studied the radio-clinic correlations.
Results: After surgery, all the operated condyles developed a new cortical bone. We noticed also a thickening of the glenoid fossa. Surgical condylectomy leaded to a 43.5% volume reduction on the operated side and 2.14% on the controlateral side. On the controlateral side, most of abnormalities seen preoperatively disappeared after surgery. For two patients, the condylar resection took away over 80% of the initial volume. For these patients, we observed major radiologic modifications on the controlateral TMJ associated with symptoms of dysfunction. These problems did not worsen their quality of life.
Conclusion: Both TMJ presented with bone remodelling after condylectomy. In condylar hyperplasia, condylectomy provides orthopaedic results on dysmorphia and removal of the pathological prechondroblastic zone. In the future, an earlier detection of this pathology may help the surgeon to treat in childhood. This would limit surgical excision and would avoid important dysmorphia.

Objective: This study aims to utilize bioinformatics and network pharmacology to identify the active components of Bushen Tiansui decoction (BSTSD) and elucidate its molecular mechanisms and targets in promoting delayed fracture healing.
Materials And Methods: Using various databases and tools, we identified 155 active compounds within BSTSD's herbal components. Key compounds such as eriodictyol and β-sitosterol were noted for their significant anti-inflammatory, antioxidant, and immunomodulatory effects, which are crucial for promoting fracture healing.

Objective: Titanium surface modifications improve osseointegration in dental and orthopedic implants. However, soft tissue cells can also reach the implant surface in immediate loading protocols. While previous research focused on osteogenic cells, the early response of soft tissue cells still needs to be better understood.

The journey of bone repair is a lengthy process. Traditionally, oral or topical medications have been employed to facilitate healing, approaches that are not only costly but may also lead to adverse effects such as gastrointestinal damage. With advancements in electrophysiology, the significance of bioelectric activity in tissue repair has become increasingly prominent, thereby enhancing the focus on research into electroacupuncture (EA) for bone repair.

Purpose Of Review: The purpose of this review is to summarize the current understanding of cell-autonomous innate immune pathways that contribute to bone homeostasis and disease.
Recent Findings: Germ-line encoded pattern recognition receptors (PRRs) are the first line of defense against danger and infections. In the bone microenvironment, PRRs and downstream signaling pathways, that mount immune defense, interface intimately with the core cellular processes in bone cells to alter bone formation and resorption.

Purpose Of Review: Bone marrow adipose tissue is a distinctive fat depot located within the skeleton, with the potential to influence both local and systemic metabolic processes. Although significant strides have been made in understanding bone marrow adipose tissue over the past decade, many questions remain regarding their precise lineage and functional roles.
Recent Findings: Recent studies have highlighted bone marrow adipose tissue's involvement in continuous cross-talk with other organs and systems, exerting both endocrine and paracrine functions that play a crucial role in metabolic homeostasis, skeletal remodeling, hematopoiesis, and the progression of bone metastases.
