Objective: The study aims to compare differences among iliac bone flaps with different iliac crest orientations for the repair of mandibular defects with an aim to analyze their advantages, disadvantages, and effects.
Material And Methods: Clinical data and computed tomography scans of all patients who underwent iliac bone flap repair of the mandible in Peking University School and Hospital of Stomatology from January 2016 to April 2021 were collected. Patients were divided into the iliac crest towards alveolar process (Group A) and the iliac crest towards mandibular inferior margin (Group B). Software was used to measure corresponding indicators. The results obtained for the groups were statistically analyzed.
Results: The study included 78 patients (25 and 53 in groups A and B, respectively). The symmetry of the LC-type defect was better in group A (p < 0.05). The all-bone width of the alveolar process side in group A was greater than 6 mm; in 15 cases of group B, the width was less than 6 mm (p < 0.05). The intermaxillary distance of two sites were higher in group B (p < 0.05). The bone cortical thickness was significantly thicker in group A (p < 0.05).
Conclusion: One year after the mandibular body defect was reconstructed with a vascularized iliac bone flap, the iliac crest towards alveolar process group showed better bone symmetry, width, intermaxillary distance, and cortical thickness to meet the planting requirements.
Clinical Relevance: The use of an iliac crest towards alveolar process may be a better approach for mandible reconstruction.

Background: Vertebral body defects pose a significant challenge in spinal reconstructive surgery. Compression fractures of the vertebral corpus are typically treated with vertebral augmentation procedures. There are significant risks associated with the introduction of foreign material in the spine, including infection and pseudarthrosis.

Introduction: Surgical treatment of pelvic girdle pain (PGP) involves arthrodesis of sacroiliac (SI) and pubic symphysis joints. Fusion of pubic symphysis involves the implantation of an autologous iliac crest tricortical graft harvested from the iliac crest. The objective was to assess the safety of a novel synthetic graft substitute (b.

Background: Surgical management methods for Hepple IV-V osteochondral lesions of the talus (OLT) are diverse. This study aimed to compare the clinical efficacy of arthroscopic autologous cancellous bone grafting and medial malleolar osteotomy combined with autologous periosteal iliac bone grafting in the treatment of medial Hepple IV-V OLT.
Methods: A retrospective analysis of clinical data from patients who underwent surgical treatment for Hepple IV-V OLT (2020-2023) was conducted.

Background: To investigate and quantify the influence of body mass index (BMI) on the efficacy and outcomes of percutaneous transforaminal endoscopic surgery (PTES), a novel minimally invasive surgical technique in the treatment of lumbar disc herniation (LDH).
Methods: A total of 55 patients suffering from single-level LDH with or without high iliac crest, scoliosis or calcification, who underwent PTES in our department from January 2019 to December 2021 were retrospectively analyzed. Patients were divided into two groups according to BMI.

Background: No appropriate studies have been conducted that compare the biomechanical properties of different fenestration positions in deep circumflex iliac artery (DCIA)-vascularized iliac bone grafts for femoral head necrosis (ONFH) treatment. In this study, we aimed to explore the fenestration locations of DCIA-vascularized iliac grafting in ONFH treatment using FEA and clinical retrospective analysis.
Methods: We simulated an iliac bone flap transplantation with a vascularized tip by finite element analysis (FEA).
