Background: Autogenous bone grafts remain the "gold standard" in maxillofacial reconstructive procedures. The objective of this study was to evaluate the proximal tibia as a donor site of cancellous bone for bone grafting procedures of the mandible on the basis of intraoperative parameters and clinical observations.
Methods: The study was based on a medical record search of 40 patients who underwent surgical procedures because of benign pathological lesions of the jaws resulting in 3-wall bone defects of the mandible and qualified for surgical removal of the lesion with simultaneous bone grafting of the defect with autogenous cancellous bone harvested from the proximal tibia.
Results: The use of the proximal tibia for bone grafting procedures enables large amounts of cancellous bone (15.09 cc in average) to be obtained. The procedure is characterized by a low risk of early and late complications, which include excessive bleeding, wound infection, lengthy healing time, scars, a loss of sensation around the scars, aching, a dip in bone, swelling and tenderness.
Conclusions: The ability to obtain large amounts of cancellous bone and a low risk of intra- and postoperative complications make the proximal tibia an attractive donor site for the bone grafting procedures in maxillofacial surgery.

By establishing micro finite element models of cement-bone composite materials and fusion surgery models (C4-C7), the mechanical properties of cement-bone composite materials (Polymethyl methacrylate (PMMA) and a mixture of PMMA and calcium phosphate bone cement (PMMA/CPC)) were analyzed, and the influence of bone cement on the biomechanical properties of anterior cervical discectomy fusion surgery with partial vertebral osteotomy was evaluated. The results revealed that compared with bone cement, the elastic modulus of cement-bone composite material decreased, the PMMA/CPC+bone (osteoporosis) decreased by 73.65% compared to PMMA/CPC.

Crestal placement of short plateau implants in compromised jaws may cause implant failure due to bone overstress. The aim was to evaluate the impact of different sized implants on adjacent bone overload and the implant load-bearing ability in terms of the proposed index-ultimate functional load (UFL). Three-dimensional models of osseointegrated implants placed in types III and IV bone were analysed by the FEM for the case of patient-specific variations in cortical bone elasticity modulus.

Background: Ankle arthrodesis is the most frequently performed salvage procedure for pyogenic arthritis. However, its failed fusion rate of approximately 15% has been considered problematic. Herein, we present a case of pyogenic ankle arthritis successfully treated via a two-stage surgical procedure on the basis of the induced membrane technique.

This study is to evaluate the effectiveness of autologous platelet-rich fibrin (PRF) combined with ultra-pulsed carbon dioxide laser in treating cancellous bone-exposed wounds. A total of 65 patients with cancellous bone-exposed wounds were retrospectively analyzed selected. There were 35 cases in ultra-pulsed carbon dioxide laser + PRF group (Laser group, group L), and 30 cases in routine surgical debridement + PRF group (Routine group, group R).

This study aims to investigate the relationship between the spatial distribution and heterogeneity of lumbar vertebral trabecular volumetric bone mineral density (vBMD) and osteoporotic vertebral fractures(OVF). This retrospective study included the L1 and L2 vertebrae of 143 participants with osteoporotic vertebral fractures and 429 age- and sex-matched no-fractured controls. Spatial distribution was assessed using the superior/middle and inferior/middle ratios, while heterogeneity was indicated by the quartile coefficient of variation (QCV) and interquartile range (IQR).
