OBJECTIVES: To evaluate the mid-term clinical performance of direct composite restorations placed in patients with pathological tooth wear needing full rehabilitation with an increase of vertical dimension of occlusion. METHODS: In a prospective trial 34 patients (34.0 ± 8.4 years; 25 males, 9 females) were treated with a minimal invasive additive technique using composite restorations. The restorative treatment protocol was to provide all teeth with composite build-up restorations in an increased vertical dimension of occlusion (VDO) using the DSO-technique...

BACKGROUND Spinal burst fractures are pathologies that occur in spinal injuries and cause significant mortality and morbidity as a result. Burst fractures in spinal cord injuries can result in rapid and significant oxidative stress. In addition to the primary injury in severe spinal cord injuries, subsequent secondary lesions are mainly due to inflammatory cascade activation and excessive production of free radicals. This study evaluated oxidative stress and antioxidant enzyme levels in burst fractures. MATERIAL AND METHODS Twenty patients with burst fractures were diagnosed and underwent surgery and 20 healthy control subjects were included in the study...

BACKGROUND: There is no clear consensus on the relationship between tenofovir (TDF) and fracture risk because the studies published so far present contradictory findings. STUDY QUESTION: Our objective was to detect, from the European pharmacovigilance database (EudraVigilance), a signal of fracture risk during TDF exposure in patients infected with HIV. METHODS: Herein, we analyze all the cases of fractures suspected to be related to TDF recorded in EudraVigilance between 2001 and November 10, 2016...

BACKGROUND: Falling from a distance is an important issue worldwide, which happens in different ages, genders and circumstances. It is usually not considered a medicolegal case in many countries hence no autopsy is performed. This study focused on analyzing injuries sustained in victims of falling in relation to different distances of fall. METHODS: Retrospective study of 352 autopsy reports of falling victims brought to the forensic pathology department at Jordan University Hospital during the period from January 1990 to March 2016...

PURPOSE: Superimposed three-dimensional (3D)-models obtained from CT-images have been used to evaluate displacement of femoral neck fractures, but this method assumes symmetrical anatomy of normal femurs. The present study aimed to compare the spatial orientation of the left and right proximal femur, thus establishing if 3D models can be used as a reference standard for the evaluation of fracture displacement. METHODS: We generated 3D-CT-models of 20 patients with no skeletal pathology of the proximal femurs...

BACKGROUND: Gastroesophageal reflux disease (GERD) is a factor that has a significant negative impact on the quality of life (QoL). Vertebral fractures and/or spinal malalignment may influence the frequency of GERD. However, the epidemiology and pathology of GERD in patients with adult spinal deformity (ASD) are still largely unknown. To establish the optimal surgical strategy for GERD in patients treated surgically for ASD, we sought to clarify the GERD prevalence, determine radiographically which spinal malalignment parameters influence GERD risk, and evaluate GERD improvement postoperatively...

BACKGROUND: Patients who present for a trauma workup often have a head computed tomography (CT) performed to identify intracranial pathology. Facial fractures are routinely identified in these patients, and further imaging is the norm with dedicated facial CT scans. Additional imaging increases radiation doses; however, it is unclear if additional operative fractures are identified. The aim of this study was to examine differences between these 2 CT imaging modalities. METHODS: A retrospective review of all operative facial trauma patients receiving both head and facial scans at a single institution was performed (1999-2012)...

We sought to determine if vertebral trabecular attenuation values measured on routine body CT scans obtained for a variety of unrelated indications can predict future osteoporotic fractures at multiple skeletal sites. For this HIPAA-compliant and IRB-approved retrospective cohort study, trabecular attenuation of the first lumbar vertebra was measured in 1966 consecutive older adults who underwent chest and/or abdominal CT at a single institution over the course of one year. New pathologic fragility fractures that occurred after a patient's CT study date were identified through an electronic health record database query using ICD-9 codes for vertebral, hip, and extremity fractures...

RATIONALE: Desmoplastic fibroma (DF) is a rare, locally invasive but benign bone tumor. It represents one of the rarest bone diseases, with an incidence of only 0.11% of all primary bone tumors. PATIENT CONCERNS: Herein, a case of massive and unusual DF, with simultaneous involvement of ilium and ischium, is described. A 29-year-old man suffered minor pain in his right hip for 2 years. It worsened after sudden movements, which prevented him from walking normally...

OBJECTIVE: Kyphoplasty and vertebroplasty have become one of the most frequent surgical procedures in the treatment of vertebral compression fractures. Often, the cause of compression fractures is lowered bone mineral density as in osteoporosis. In the differential workup, also pathologic vertebral compression fractures need to be ruled out. Importantly, imaging techniques alone cannot safely differentiate between invasive lymphatic and osteoporotic vertebral fracture. Our goal was to identify the degree of unexpected positive histology in kyphoplasty for presumed osteoporotic vertebral compression fracture...

The torsion of the humerus describes the physiological rotation of the humerus around its longitudinal axis. Various clinical and radiological methods for measurement have been described. The computed tomography method is currently the gold standard. The angle between the humeral head axis and the transepicondylar axis is measured. This angle is called retroversion. Values of retroversion vary between 10° and 40°. For the treatment of many humeral pathologies, a precise reconstruction of the anatomical retroversion is required...

AIMS: Dislocation rates are reportedly lower in patients requiring proximal femoral hemiarthroplasty than for patients undergoing hip arthroplasty for neoplasia. Without acetabular replacement, pain due to acetabular wear necessitating revision surgery has been described. We aimed to determine whether wear of the native acetabulum following hemiarthroplasty necessitates revision surgery with secondary replacement of the acetabulum after proximal femoral replacement (PFR) for tumour reconstruction...

The consolidated way of diagnosing and treating osteoporosis in order to prevent fragility fractures has recently been questioned by some papers, which complained of overdiagnosis and consequent overtreatment of this pathology with underestimating other causes of the fragility fractures, like falls. A new clinical approach is proposed for identifying the subgroup of patients prone to fragility fractures. This retrospective observational study was conducted from January to June 2015 at the Nuclear Medicine-Bone Metabolic Unit of the of the Fondazione IRCCS Ca' Granda, Milan, Italy...

PURPOSE: The association between delayed hip fracture surgery and mortality remains elusive because of strong confounding by comorbidity factors. We designed a study to investigate the effect of small delays in surgery due to holidays. METHODS: Consecutive hip fractures operated in a high-income, publicly funded healthcare system between 2006 and 2013 were analysed. Age <65 years, pathological fractures, history of previous hip operation and time to surgery >seven days were excluded...

Background: Bone metastases are common in hepatocellular carcinoma (HCC), but their incidence, morbidity, and mortality are not well defined. Methods: The Memorial Sloan Kettering Cancer Center database was queried for all patients with HCC and metastases seen from 2002 to 2014. The prevalence of bone metastasis was determined and cumulative incidence function was used to estimate the probability of developing a bone metastasis. Regression models were created to identify risk factors for osseous metastasis...

CASE: We present a case of a pathologic vertebral fracture and encroachment into the spinal canal from a vertebral hemangioma in a 13-year-old boy. The original approach of embolization followed by an anterior-posterior resection and stabilization through a costotransversectomy had to be converted intraoperatively to a combined anterior and posterior approach secondary to excessive bleeding. CONCLUSION: Because of the hypervascularity and the extensive nature of aggressive vertebral hemangiomas, surgeons attempting procedures similar to the case described herein must be prepared to adapt to the circumstances when preoperative embolization is not totally effective...
