Maxillofacial fracture epidemiology and treatment plans in the Northeast of Iran: A retrospective study
2017
Background: The epidemiology of facial injuries varies based on lifestyle, cultural background and socioeconomic status in different countries and geographic zones. This study evaluated the epidemiology of maxillofacial fractures and treatment plans in hospitalized patients in Northeast of Iran (2015-2016). Material and Methods: In this retrospective study, the medical records of 502 hospitalized patients were evaluated in the Department of Maxillofacial Surgery in Kamyab Hospital in Mashhad, Iran. The type and cause of fractures and treatment plans were recorded in a checklist. Data were analyzed with Mann–Whitney test, chi-squared test and Fisher’s exact test, using SPSS 21. Results: The …
Retrospective study maxillofacial fractures epidemiology and treatment plans in Southeast of Iran
2015
Background: The epidemiology of facial injuries varies in different countries and geographic zones. Population concentration, lifestyle, cultural background, and socioeconomic status can affect the prevalence of maxillofacial injuries. Therefore, in this study, we evaluated the maxillofacial fractures epidemiology and treatment plans in hospitalized patients (2012-2014) which would be useful for better policy making strategies. Material and Methods: In this retrospective study, the medical records of 386 hospitalized patients were evaluated from the department of maxillofacial surgery at Bahonar Hospital of Kerman, Iran. The type and cause of fractures and treatment plans were recorded in a…
Accuracy of two plasma antibody tests and faecal antigen test for non-invasive detection of H. pylori in middle-aged Caucasian general population sam…
2018
The aim of the study was to assess the accuracy of two plasma Helicobacter pylori (H. pylori) antibody test-systems and a stool antigen test (SAT) system in a general population sample in Latvia.Blood and faecal samples were analysed in healthy individuals (40-64 years), referred for upper gastrointestinal endoscopy according to pilot study protocol within a population-based study investigating gastric cancer prevention strategies (GISTAR pilot study). Antibodies to H. pylori were assessed in plasma by latex-agglutination test and enzyme-linked immunosorbent assay (ELISA). H. pylori antigen in faecal samples was detected by a monoclonal enzyme immunoassay-based SAT. Histological assessment …
Axis Rotation and Visually Induced Motion Sickness: The Role of Combined Roll, Pitch, and Yaw Motion
2011
A well-known phenomenon in aviation and in virtual environments such as simulators or computer games is motion sickness (MS). The amount of sensory conflict is thought to be responsible for the severity of MS, which should increase with the complexity of the simulated motion. The focus of the present study is on the direction and complexity of simulated body rotations in the genesis and severity of visually induced MS. The methods utilized for this study are as follows: Three simulated rollercoaster rides including translational movement in the fore-aft axis and additional rotational motion either in pitch only, along the pitch and roll axes, or in pitch, roll, and yaw were generated. The a…
Complex radial head and neck fractures treated with modern locking plate fixation
2019
Background Internal fixation of complex radial head and neck (CRHN) fractures is difficult, and postoperative complications are common. This study evaluated elbow function and patient clinical status after internal fixation of CRHN fractures with modern locking plates. Methods We included 40 patients with 41 fractures (1 bilateral lesion). In 25 patients (61%), a concomitant injury was found. Patients were an average age of 46 years (range, 22-70 years). The mean follow-up time was 36 months (range, 2-70 months). Postoperative assessments included evaluation of range of motion, functional scores, and radiologic findings. We assessed fracture healing, surgical complications, revision surgery…
Orthopedic and neurosurgical treatment of severe kyphosis in myelomeningocele
1999
Kyphosis in myelomeningocele is characterized by a complex pattern of problems during development and therapy. On the one hand, decompensation of upright posture leads to loss of sitting ability and social integration; on the other hand, accompanying malformations and trophic alterations threaten the physical integrity and performance. Neurologic function, cerebrospinal fluid (CSF) circulation, skeletal deformity and the urinary transport system need to be kept in mind and need to be treated with cooperation between the different specialties. Especially during serious surgical interventions such as spinal surgery, neither the nervous system nor the kidneys must be ignored. Sixteen patients …
Predicting the failure in distal femur fractures.
2018
Abstract Introduction The incidence of nonunion after fractures of the distal femur is up to 6%. The distal femoral nonunion is a disabling disease that needs complex steps in his treatment. Aim of our study is to find predicting factors of non-unions. Materials and methods We retrospectively analyzed 116 cases of distal femoral fractures and 20 cases of non-unions. In both surgeries we analyzed: accuracy of reduction, stability of fixation, hardware used, residual medial or lateral bone defect, use of autologous or heterologous bone grafts. Results Malreduction, particularly axial defect, associated with unbalanced fixation, and a medial cortical bone defect of greater or lesser extent wer…
Autologous Iliac Bone Graft Compared with Biphasic Hydroxyapatite and Calcium Sulfate Cement for the Treatment of Bone Defects in Tibial Plateau Frac…
2019
Background Bone-graft substitutes are commonly used for the augmentation of traumatic bone defects in tibial plateau fractures. However, their clinical performance compared with that of autologous bone-grafting, the gold standard in bone defect reconstruction, still remains under debate. This study investigates the differences in quality of life, pain, and radiographic outcomes in the treatment of tibial plateau fracture-associated bone defects with either autologous bone grafts or a bioresorbable hydroxyapatite and calcium sulfate cement (CERAMENT BONE VOID FILLER [CBVF]; BONESUPPORT). Methods In this study, 135 patients with acute depression and split-depression fractures of the proximal …
The challenges of monoaxial bone transport in orthopedics and traumatology
2017
Background. Bone defects represent the main challenging problem for the orthopedic surgeon and, consequently, they increase the duration of hospitalization, risk of complications and health expenditures. The aim of our observational, descriptive and retrospective study is to evaluate the outcomes of patients treated with a monolateral external fixator for bone defects greater than 3 cm. Material and methods. Between January 2003 and January 2013, 21 patients were treated at our center by bone transfer with a monolateral external fixator. The main etiologies were trauma in 17 cases (80.9%) and tumors in 4 cases (19.1%). Mean follow-up was 5 years for non-union and 3 years for tumors. Our cl…
Operative Treatment of Scoliosis With Cotrel-Dubousset-Hopf Instrumentation
1997
Study design This study analyzes the effects of a new anterior spinal instrumentation system and the results of use in 50 patients with scoliosis. Objectives Anterior spine systems are reviewed. The principles of a new anterior spinal instrumentation system allowing for postoperative care without external support are discussed. Summary of background data Numerous different implants have been presented in the literature for anterior spinal surgery. Nevertheless a primary stable anterior instrumentation was not available for multisegmental procedures until now, and the restoration of lordosis in the lumbar spine was very difficult with the common devices. The development of more stable device…
