With the rapid advancement of digital and microsurgical techniques, immediate autologous bone grafting following resection of benign and malignant mandibular tumors has become a standard treatment. However, some patients are unable to undergo immediate autologous bone grafting due to various reasons. In such cases, titanium plate implantation (or combined with soft tissue free flap such as anterolateral thigh flap) serves as an alternative to prevent airway compression and maintain facial shape and function. This article reports a case of a patient, referred to as patient 1, who experienced a recurrence of mandibular leiomyosarcoma and was unable to undergo immediate autologous bone grafting. Instead, an immediate titanium plate implantation was chosen to restore the patient's facial contour and esthetics. Although this method addresses functional and esthetic issues in the short term, a high risk of titanium plate exposure, which is shown in patient 2, adversely affects life quality. After systematic evaluation, the decision was made to retain and continue using the original titanium plate and screws and perform autologous fibula flap transplantation to repair the mandibular defect. Surgical procedures included titanium plate removal and debridement, bilateral partial mandibular resection and osteoplasty, preparation of the free fibula flap, and placement with fixation using the original titanium plate. Postoperative follow-up showed successful flap healing without complications, and the patient was satisfied with her postoperative appearance. This innovative strategy, under strict indications, can reduce the financial burden on patients, maintain occlusal relationships, and significantly improve postoperative quality of life.

Objective: We designed a new distractor pairing a bioabsorbable upper fixing plate fixed by bioabsorbable screws with a traditional titanium distractor to simplify the second surgery removing the distractor after mandibular distraction osteogenesis. The present study aims to evaluate its biomechanical properties using finite element method.
Materials And Methods: Ten computer-aided designed models simulating mandibles of 5 patients under 2 working conditions, the instance of distraction and mastication, were produced.

This study aimed to evaluate the near-cortical over-drilling technique on the mechanical behaviour of bone-plate constructs in a rabbit transverse femoral fracture. In vitro biomechanical testing and finite element (FE) models were used for analyses. Rabbits' bones (n = 14) were divided into two groups: G1 - without near-cortical over-drilling, and G2 - with near-cortical over-drilling.

A retrospective analysis of 47 consecutive patients treated between January 2022 and June 2024 documented operative time, intraoperative blood loss, fluoroscopy times, healing time, complications, postoperative fracture gap distance (mm), and articular surface step-off (mm) at the ankle joint. Ankle function was assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, the Manchester-Oxford Foot Questionnaire (MOXFQ), and range of motion measurements at 3, 6, 12, and 14 months.

Segmental mandibulectomy is a valid treatment for advanced medication-related osteonecrosis of the jaw (MRONJ), but subsequent reconstruction is challenging. Spontaneous bone regeneration (SBR) following resection is exceedingly rare, particularly in the elderly. We present the case of a 63-year-old woman with stage 3 MRONJ who underwent a 60 mm segmental mandibulectomy.

Background/objective: Plate failure, including bending, is a critical issue in orthopedic fracture fixation, with clinical failure rates of 3.5%-19%, burdening patients and healthcare systems. Preclinical ovine models have observed similar plate bending due to overloading.
