BACKGROUND: Dislocated pelvic fractures which require surgical repair are usually operated on via open surgery. Approach-related morbidity is reported with a frequency of up to 30%. The aim of this anatomical study was to prove the feasibility of endoscopic visualisation of the relevant anatomical structures in pelvic surgery and to perform completely endoscopic plate osteosynthesis of the acetabulum with available standard laparoscopic instruments. METHOD: In four human cadavers, we established an endoscopic preparation of the complete pelvic ring, from the symphysis to the iliosacral joint, including the quadrilateral plate and the sciatic nerve, and performed endoscopic plate osteosynthesis along the iliopectineal line...

Objective: The use of open reduction and internal fixation (ORIF) for unstable pelvic injuries is associated with extensive blood loss, iatrogenic neurovascular injury, and infection. Moreover, the placement of sacroiliac (SI) screws is a blinded procedure, guided primarily by palpation and two-dimensional radiological screening, which demands expertise. The complex three-dimensional anatomy of SI joint and its proximity to neurovascular structure require a safe and precise technique...

OBJECTIVE: In polytrauma patients, to limit the pelvic space favouring internal bleeding, the use of pelvic binders is now a standard practice. In case of external pelvic binder placement with anatomic reduction of the symphyseal and sacroiliac joints, delayed diagnosis and missed injuries could occur. The aim of this study is to document the risk of missed diagnosis, as well as to identify a possible algorithm for optimal management of traumatized patients with pelvic binders, in order to reach an early diagnosis of pelvic fractures without additional risks...

This study aims to identify and distinguish various factors that may influence the clinical symptoms (limited mouth opening and malocclusion) in patients with maxillofacial fractures. From January 2000 to December 2009, 963 patients with maxillofacial fractures were enrolled in this statistical study to aid in evaluating the association between various risk factors and clinical symptoms. Patients with fractured posterior mandibles tended to experience serious limitation in mouth opening. Patients who sustained coronoid fractures have the highest risk of serious limitation in mouth opening (OR = 9...

PURPOSE: The aim of this study was to determine the effect of bone mineral density (BMD) on the stress distribution in pelvic-hip complex (PHC) model which included bone structures and soft tissues. Bone mass changes in osteoporosis and osteopenia were considered in this analysis. In addition, the relations between force direction and stress distribution causing PHC fractures were determined. METHODS: This paper presents the development and validation of a detailed 3D finite element model with high anatomical fidelity of the PHC and BMD changes in trabecular and cortical bones, modelled based on CT scans...

INTRODUCTION: Massive hemorrhage is often associated with unstable pelvic fractures with posterior ring injury. Initial pelvic radiography alone may not detect these posterior lesions. We examined whether the presence of an anterior pelvic fracture on initial pelvic radiography alone may identify patients who are at a high risk of major hemorrhage. MATERIALS AND METHODS: A total of 288 patients with pelvic fractures were admitted to the Fukui Prefectural Hospital during an 11-year period...

Facial fractures can be potentially fatal in polytraumatized patients due to retropositioning tissues to upper airway obstruction. In the first aids, this situation can be reversed using a tracheostomy procedure to break out the airways. However, fractures leading to airway obstruction are rare and according to Richards Classification can be classified into 5 types. The purpose of this article is to report a clinical patient with a bilateral condylar and mandibular symphysis fractures that resulted in airway obstruction and severe mandibular rear projection...

OBJECTIVE: To evaluate the feasibility of minimally invasive internal fixation of pelvic anterior and posterior ring for the treatment of type C pelvic fracture, and to explore its operative techniques and therapeutic efficacy. METHODS: From December 2010 to December 2015, 18 patients with type C pelvic fracture were treated by reconstructive plates fixation through minimally invasive ilioinguinal approach for pelvic anterior ring injuries, and by invasive percutaneous sacroiliac joint screw fixation for pelvic posterior ring injuries...

Mandibular fractures constitute a major portion of maxillofacial trauma and may lead to considerable functional and aesthetic sequelae if treatment is inadequate or delayed. An epidemiology study on mandibular fractures may guide the preventive efforts of the Taiwan public health care system. Therefore, a retrospective review was conducted at a medical center in central Taiwan to evaluate the current mandibular fracture epidemiology.The medical records and digitized radiographs of 198 patients who received treatment for mandibular fractures during a 3-year period (from October 2010 to September 2013) at a medical center in central Taiwan were reviewed to obtain demographic and injury data...

Introduction: The aim of the present study was to compare fixation of mandibular anterior fractures following open reduction using lag screws or miniplates. Materials and Methods: This prospective study was conducted on 20 patients diagnosed with cases of displaced mandibular anterior fractures treated with open reduction and internal fixation. The patients were then randomly allocated to either of two groups - Group A: two 2.5 mm stainless steel lag screws were placed in 10 patients...

PURPOSE: The aim of this study was to compare the fixation power of sacroiliac rod fixation (SIRF), which was developed based on our original "within ring" concept to exclude the lumbar vertebra from the fixation range, and spinopelvic fixation (SPF) in a biomechanical experiment. METHODS: SPF and SIRF were applied to the posterior element in four bones each with the pelvic ring fracture model (AO/OTA classification 61-C1.3). A 300-N axial force was loaded on the fifth lumbar vertebra of the simulated pelvis...

OBJECTIVE: To design minimal invasive screw on posterior pelvic ring and perform threedimensional finite element analysis based on a pelvis finite element model. METHODS: We measured the pelvic anatomical data of 20 healthy volunteers and identified potential designs for minimal invasive screw on posterior pelvic ring. A finite element model of pelvis was then established. Threedimensional finite element analyses were performed under static and dynamic mechanical loading,respectively...

Traumatic bone cysts (TBCs) are uncommon intraosseous lesions, classified as pseudocysts because they lack an epithelial membrane lining. The etiology of a pseudocyst has not been determined. Various hypotheses have been put forward to explain its pathogenesis, of which the traumatic-hemorrhagic theory is the most commonly accepted. Minor trauma, insufficient to cause fracture or iatrogenic injury, is commonly implicated as the stimulus initiating cyst formation. A TBC presenting after jaw fracture has been rarely reported in the literature...

Pelvic ring fractures occur in association with potentially fatal lesions, whose treatment is a priority in the polytrauma setting. As consequence, the definitive orthopedic approach may be postponed, leading patients to chronic and potentially disabling deformities. The treatment of these deformities is a challenge, requiring highly complex and staged surgical reconstructions. The ilioinguinal approach has been widely used in these surgeries, because it allows the release and mobilization of the hemipelvis and, in some cases, anterior fixation of the sacroiliac joint...

PURPOSE: We present a series of cases of mandibular symphysis fractures treated at our institution with a 3-dimensional strut plate. The aim of the present study was to confirm the stability of this fixation technique and discuss its advantages, disadvantages, and potential complications. PATIENTS AND METHODS: We designed and implemented a retrospective cohort study of patients who underwent surgery by the same surgeon at our institution from July 2012 to April 2014 for a mandible fracture with a symphysis component...
