BACKGROUND/AIM: There is no data available to show whether there is a relationship between mandibular fractures and isolated fractures of the posterior and/or latera wals of the maxillary sinus. The aim of this study was to determine whether there is a coincidence between these fracture patterns. METHODS: Four hundred large volume cone beam computed tomography scans (CBCT) of patients with a fracture of the mandible between 2008 and 2013 were analyzed retrospectively...

BACKGROUND: Avulsion fractures of the pelvic apophyses typically occur in adolescent athletes due to a sudden strong muscle contraction while growth plates are still open. The main goals of this systematic review with meta-analysis were to summarize the evidence on clinical outcome and determine the rate of return to sports after conservative versus operative treatment of avulsion fractures of the pelvis. METHODS: A systematic search of the Ovid database was performed in December 2016 to identify all published articles reporting outcome and return to preinjury sport-level after conservative or operative treatment of avulsion fractures of the pelvis in adolescent patients...

INTRODUCTION: The operative treatment of unstable pelvic injuries in paediatrics is not frequently indicated. The detailed modes of pelvic ring failure, surgical techniques, fixation choices, and peri-operative difficulties are not well reported. METHODS: From September 2010 to March 2016, 62 paediatric patients were admitted to an academic level I trauma center with the diagnosis of pelvic ring injury. Of them, 29 (17 males and 12 females) had operative fixation of unstable pelvic injuries...

Cement augmentation of pedicle screws is the gold standard for the stabilization of osteoporotic fractures of the spine. In-screw cement augmentation, in which cement is injected through the cannula, is another option for fracture stabilization of fragility fractures of the sacrum. However, biomechanical superiority of this technique compared to conventional sacroiliac screw fixation has not been tested. The present study compares the stability of cement-augmented and non-cement-augmented sacroiliac screw fixation in osteoporotic sacrum fractures under cyclic loading...

BACKGROUND: Floating pubic symphysis (FPS) is a relatively rare injury caused by high-energy mechanisms. There are several fixation methods used to treat FPS, including external fixation, subcutaneous fixation, internal fixation, and percutaneous cannulated screw fixation. To choose the appropriate fixation, it is necessary to study the biomechanical performance of these different methods. The goal of this study was to compare the biomechanical characteristics of six methods by finite element analysis...

BACKGROUND: Although internal fixation is the definitive treatment in unstable pelvic fractures with disruption of the anterior arch and a vertical fracture of the sacrum (AO type C1.3), there have been no agreement of the best technique of internal fixation yet. We aimed to derive comparable objective data on stiffness and load to failure in this type of fracture fixations. METHODS: Synbone was modified into AO type C1.3 fracture model, while treatments were divided into six internal fixation treatment groups using tension band plate (TBP), symphysis pubis plate (SP) with iliosacral screw at S1 and S2 (IS S1-S2), pubic screw (PS) with iliosacral TBP, PS and IS S1-S2, SP and IS S1-S3, PS and S1-S3 and finally PS and IS S1-S3...

BACKGROUND: The psoas minor partially inserted to the superior pelvic brim. And the plate used to fix the acetabular fracture has always been positioned at the pelvic brim after reduction through the Stoppa approach. However, there are few studies depicting the clinical significance of the psoas minor. The purpose of this paper was to explore the relationship between the insertion of the psoas minor tendon at the pelvic brim (IPMTPB) and screw placement through the Stoppa approach. MATERIALS AND METHODS: Fifteen cadavers were dissected for adequate exposure to IPMTPB in our study...

INTRODUCTION: Recently, robotic-assisted thymectomy (RAT) has emerged as an alternative to either, an open transsternal approach or to a video-assisted thoracoscopic approach, for both thymic tumors and benign lesions. We have reviewed our early experience with RAT to assess the associated learning curve as well as the short-term perioperative outcomes. METHODS: A prospectively collected database was reviewed for patients who underwent RAT for all causes in the period 2012-2016...

BACKGROUND: Traumatic disruption of the pelvic ring is a significant cause of life-threatening hemorrhage. For those patients who survive the initial injury, these fractures are associated with long periods of immobilization and intense rehabilitation. There is little published information available regarding long-term functional outcomes in these patients. This study evaluated the impact of severe pelvic fractures on those long-term outcomes. METHODS: All patients with severe pelvic fractures over an 18-year period were identified...

Purulent inflammation of the pubic symphysis is a rare condition involving the symphysis and parasymphyseal parts of the pubic bones. It is usually found in immuno-compromised patients and its most frequent cause is Staphylococcus aureus. Conservative treatment is based on long-term administration of antibiotics and has been efficient, as reported, in about 50% of the patients. The authors treated five patients with a late diagnosis of purulent infection of the pubic symphysis in whom the antibiotic therapy had to be completed by surgical intervention...

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...
