The aim of this study was to investigate the sacroiliac joint injury mechanism. Two test configurations were selected from full scale car crashes conducted with the WorldSID 50(th) dummy resulting in high sacroiliac joint loads and low pubic symphysis force, i.e. severe conditions for the sacroiliac joint. The two test conditions were reproduced in laboratory using a 150-155 kg guided probe propelled respectively at 8 m/s and 7.5 m/s and with different shapes and orientations for the plate impacting the pelvis...

BACKGROUND There is no single approach that provides adequate exposure for treatment of all types of acetabular fractures. We describe our experience with an easier, relatively less invasive pubic symphysis approach (PSA) for the treatment of acetabular fractures. MATERIAL AND METHODS Between March 2011 and March 2012, fifteen patients with acetabular fracture underwent surgery using the PSA technique. Fracture reduction and treatment outcomes were assessed by clinical and radiological examination. Operation time, intraoperative blood loss and postoperative complications were documented...

INTRODUCTION: Urological injuries in pelvic fractures are noticed in 6-15% of the cases. The bladder, due to its anatomical position, is prone to rupture in pelvic fractures. The majority of urinary bladder injuries are either extraperitoneal or intraperitoneal. Nonetheless, both types can occur simultaneously in 6% of the cases. PRESENTATION OF THE CASE: A 45-year-old male was brought to our emergency department after being struck by an automobile. In the absence of signs of urethral injury, a Foley's catheter was inserted revealing gross hematuria...

OBJECTIVES: The current biomechanical work compares the symphyseal and sacroiliac stability obtained with two systems of bone osteosynthesis. The two methods of fixation compared were the 6-hole suprapubic non-locked plate and pubic fixation with two cannulated screws, a novel technique that can be applied percutaneously in the clinical practice. The aim of this study was to examine the validity of the use of two-cannulated-screws osteosynthesis in order to minimize the secondary effects of open fixation, especially in patients in whom an open reduction is contraindicated...

OBJECTIVE: Pelvic binders may hinder radiologic assessment of pelvic instability after trauma, and avulsive injuries can potentially unmask instability in this setting. We compare the performance of MDCT for the detection of pelvic disruptions in patients with binders to a matched cohort without binders, and we assess the utility of avulsive injuries as signs of pelvic instability. MATERIALS AND METHODS: MDCT examinations of 56 patients with binders were compared with MDCT examinations of 54 patients without binders...

Mandibular fractures in the neonate are rare. The aetiological factors are traumatic delivery, accidental fall, road traffic accidents, and attempted infanticide. The diagnosis is difficult due to facial oedema masking the clinical features and the absence of dentition. The treatment of fractures in the newborn represents a unique problem in terms of investigations, diagnosis, selection of anaesthesia, and method of fixation. The case of a 1-day-old infant referred for the management of a mandibular fracture sustained in an accidental fall is presented herein...

Operative treatment of sacral insufficiency fractures is frequently being complicated by osteopenic bone properties. Cement augmentation of implanted sacroiliac screws may lead to superior construct stability and prevent mechanical complications. A novel hemi-pelvis test model with dissected symphysis was developed. Five fresh-frozen cadaveric pelvises were vertically osteotomized at the sacrum on both sides and fixed with sacroiliac screws in both corridors of the first sacral vertebral body. One side was randomly augmented with bone cement...

: Femoral neck and pelvic fractures are rarely encountered in the pediatric population secondary to the resilient nature of the immature skeleton. Both fracture types usually result from high-energy blunt trauma including motor vehicle collisions, motor vehicle-pedestrian accidents, and falls from height. Considerable studies have been published on the natural history, management, and complications of pediatric pelvis and femoral neck fractures. However, few case reports have documented both fracture types in the same patient...

OBJECTIVES: The study's aim is to calculate the parameters for retrograde insertion points for fixed superior pubic ramus fractures. METHODS: From the pubic symphysis, diameter and length of the screw were measured, as well as the angle between the screw axis and the 3 planes. RESULTS: When the diameter was fixed at 4.5 mm, the maximum lengths were 125 mm and 119 mm. CONCLUSIONS: When the fracture occurs in Zone I, the penetration point could be selected in the pubic symphysis pubis angle to ensure that medial fracture fragments have sufficient screw channel length...

Traumatic pubic symphysis diastases (PSD) are life-threatening injuries that often require operative fixation. The purpose of this review is to evaluate the outcomes of patients following various operative fixation techniques of these particular pelvic ring injuries. Specifically, we will analyze the role of: (1) surgical approach; (2) implant failure; and (3) fixation methods in treating traumatic PSD. They are typically fixed using the Pfannestiel approach, but a midline approach may be used in cases where this is not ideal...

Anteromedial fracture dislocation of the mandibular condyle is common but a superolateral dislocation of an intact condyle is quite rare. This type of dislocation is often misdiagnosed or completely overlooked and hence inadequately addressed. We report a case of a 41-year-old male patient who experienced superolateral dislocation of the intact condyle with symphysis fracture and panfacial fracture following a road-traffic accident, and review of literature of superolateral dislocations from 1967 to 2014.

INTRODUCTION: Management of mandibular condylar fractures is difficult in children with their inherently dynamic and unstable deciduous and mixed dentitions. We present a variation of the conservative fixed orthodontic approach that was used as an adjunct to aid in the reduction of a bilateral condylar fracture in a pediatric patient. METHODS: A boy, aged 10 years 9 months, came with clinical signs and symptoms of mandibular fracture after being involved in a motor vehicle accident...

The purpose of this case report is to describe an interdisciplinary approach for a 51-year-old male who underwent multiple facial fractures including bilateral condyle fractures. The patient underwent emergency surgery, which included open reduction of the maxilla and mandibular symphysis and closed reduction of the bilateral condyle fractures. Although the patient recovered a comfortable range of mouth opening and alleviation of the temporomandibular joint (TMJ) symptoms after surgery, he suffered from a large anterior-posterior discrepancy due to less stability on the condyle-fossa relationships and from open bite with contacts only on both second molars and right second premolars...

Osteogenesis imperfecta (OI) is a congenital disease characterized by bone fragility and low bone mass. Despite the variety of its manifestation and severity, facial fractures occur very infrequently. Here, we report a case of an infant diagnosed with OI after mandibular and lower limb fractures. A boy aged 1 year and 3 months was brought to his neighboring hospital with a complaint of facial injury. He was transferred to our hospital to undergo operation 3 days later. Computed tomography images revealed multiple mandibular fractures including complete fracture in the symphysis and dislocated condylar fracture on the right side...

There is an established association between ED and pelvic fracture urethral injuries (PFUIs). However, ED can occur after the injury and/or the urethral repair. To our knowledge, only one study of erectile function (EF) after urethroplasty for PFUIs used a validated questionnaire. This study was carried out to determine the impact of anastomotic posterior urethroplasty for PFUIs on EF. We retrospectively reviewed the computerized surgical records to identify patients who underwent anastomotic urethroplasty for PFUIs from 1998 to 2014...

Pelvic ring fractures when caused by trauma, either violent or in demineralized bone, generally consist of injuries in both the anterior (pubic symphysis and rami) and posterior (iliac wing, sacrum, sacroiliac joint) portions. Injury classifications are based on injury mechanism and pelvic stability, and are used to determine treatment. Acetabular fractures, associated or not to pelvic ring disruption, are classified on the basis of fracture line, into elementary fractures of the acetabular walls, columns and roof, and into complex fractures...

BACKGROUND: The aim of this study was to compare the efficiency of resorbable and metallic plates in open reduction and internal fixation of mandible fractures in children. METHODS: Thirty-one patients (mean age, 8.05 years; range 20 months-14 years) were operated on various fractures of the mandible (26 [60.4%] symphysis- parasymphysis, 12 [27.9%] condylar-subcondylar fractures, 5 [11.6%] angulus and ramus fractures). Twelve patients were treated with resorbable plates and 19 patients with metallic plates...

OBJECTIVE: To determine trends in incidentally detected age- and gender-associated chondrocalcinosis on pelvic CT. MATERIALS AND METHODS: Twenty patients of each gender at the center of each decade of life who underwent a CT scan of the pelvis performed 2009-2013 were identified and selected for a total of 400 pelvic CTs. Images were reviewed independently by two radiologists for the presence or absence of chondrocalcinosis within the pelvis. Patients with hip or low back pain, known CPPD arthropathy or any known predisposing condition, prior hip arthroplasty, or articular fracture were excluded...

BACKGROUND: Preclinical and early clinical external pelvic stabilization using commercially available devices has become common in trauma patient care. Thus, in the emergency department an increasing number of patients will undergo radiographic evaluation of the externally stabilized pelvis to exclude injuries. While reports exist where injuries to the pelvis were elusive to radiological examination due to the pelvic immobilization we elaborate on an algorithm to remove an external pelvic stabilizing device, prevent delayed diagnosis of pelvic disruption and thus increase patient safety...
