Diagnostic measures for monitoring and follow-up in periodontology and implant dentistry.

This review discusses the role of diagnostic measures in the lifelong management of periodontal disease and peri-implant complications. After active treatment, these conditions require regular monitoring of the supporting structures of teeth and dental implants to assess bone and soft tissue health over time. Several clinical measures have been developed for the routine assessment of periodontal and peri-implant tissues, including periodontal and peri-implant probing, bleeding on probing, intraoral radiography, biomarker analysis, and microbiological testing. This review highlights the evolution of diagnostic practices, integrating traditional methods with emerging technologies such as resonance frequency analysis and ultrasound imaging to provide a holistic view of peri-implant health assessment. In addition to objective measurements, patient risk factors are considered. The goals of periodontal and peri-implant maintenance are to control disease activity and stabilize tissues through supportive care, which includes diagnostic measures at follow-up visits. This enables clinicians to monitor treatment outcomes, assess health status, and detect recurrence or progression early through routine evaluation, allowing additional interventions, including adjustment of supportive therapy intervals, to further improve and maintain periodontal and peri-implant stability over time.

Selective postmortem arterial angiography of head and neck using digital x-ray or computed tomography: A practical and rapid method to identify vascular injuries.

Identification of vascular injuries is crucial for complete postmortem evaluation and understanding of trauma deaths by the Medical Examiner. Some vascular injuries are difficult to evaluate due to challenging anatomic locations, especially in the head and neck. Documenting injuries of the facial and vertebral arteries is challenging and necessitates time-consuming dissections that can create artifacts and disfigurement. In busy medical examiner offices with a significant number of traumatic injuries, finding a creative solution to employ reliable postmortem angiography is desirable. At the Office of the Chief Medical Examiner for the State of Maryland (OCME), we created and effectively implemented a selective angiography procedure using traditional indwelling Foley catheters and water-soluble barium swallow contrast to evaluate arterial injuries using either digital radiography or computed tomography imaging modalities. This technique and imaging interpretation can be performed by a medical examiner or forensic pathology fellow after basic technical training and basic radiology training. This study outlines the technique, methods, and utilization of the procedure and describes the findings of six deaths due to vascular lesions from different injury mechanisms and disease processes and describes the ease of implementation on a broader scale in busy Medical Examiner's offices.

Radiographic assessment of the peri-implant site.

While peri-implant mucositis relies solely on clinical parameters, radiological assessment becomes indispensable for diagnosing peri-implantitis. Intraoral radiography, with its simplicity of application, low radiation exposure, and adequate representation of peri-implant structures, stands out as the standard of care for both immediate and follow-up assessments. Standardization by custom-made radiologic splints allows for excellent comparability with previous images and allows for the determination of even small changes in contour and density of the peri-implant bone. Furthermore, other radiographic modalities like panoramic radiography and cone beam computed tomography (CBCT) may provide useful features for specific patients and clinical cases while also showing innate limitations. Beyond the assessment of the marginal peri-implant bone level as the crucial parameter of clinical relevance, radiologic assessment may reveal various other findings related to the prosthetic restoration itself, the precision of its fit to the implant, and the peri-implant soft and hard tissues. Since such findings can be crucial for the assessment of peri-implant health and the implants' prognosis, a systematic diagnostic evaluation pathway for a thorough assessment is recommended to extract all relevant information from radiologic imaging. This article also provides an overview of the clinical and chronological indications for different imaging modalities in peri-implant issues.

Radiographic characterization of the maxillary septum and septal bullae in horses: An ex vivo study.

The anatomical variations of the maxillary septum and the septal bullae can generate challenges during the interpretation of radiographs of the horses' heads and make it difficult to accurately identify the sites affected in sinus disorders. The description of the radiographic appearance of these structures is currently scarce in the scientific literature. This work aims to describe the anatomical and radiographic characteristics of the maxillary septum and maxillary septal bullae in horses. Six chemically preserved equine cadaver heads were used which, after being submitted to the maxillary osseous flap, the maxillary septum and its respective bullae were identified. Radiographic examinations before and after contrast impregnation on these structures were performed. The positioning of the maxillary septum varied between the anatomical specimens and between the sides of the same specimen. The 30° oblique dorsoventral lateral and lateral projections allowed the identification of the maxillary septum and septal bullae. However, the bullae remained superimposed on the dental arches in the dorsoventral projections with the mandible in a neutral position or with the mandible displaced. The oblique offset radiographic positioning was suggested and proved effective for the examination of the maxillary septal bullae, where the mandible was displaced to the side of the bullae to be examined, and the radiographic beam inclined in the same direction. The maxillary septum and its bullae could be properly identified in a macroscopic way after the osseous flap and the contrasted radiographic examination allowed its adequate interpretation. Variations in size and position are considered normal for the equine species.

Evaluation of the performance of digital x-ray systems in pelvis radiography.

The aim of this study was to investigate the performance of eight digital radiography systems and to optimise the dose-image quality relationship for digital pelvis radiography. The study involved eight digital radiography systems used for general examinations at Vilnius University Hospital Santaros Klinikos. An anthropomorphic pelvic phantom (CIRS, US) was used to simulate a patient undergoing clinical pelvis radiography. Dose quantities ESD (entrance surface dose), DAP (dose area product) and exposure parameters (kVp, mA, mAs) were measured and the effects on the images were evaluated, considering physical CNR (contrast to noise ratio) and observer-based evaluations as image quality metrics. Increasing the tube voltage by 5 kVp from standard protocol led to a reduction in radiation dose (DAP) by 12-20% with a slight impact on image quality (CNR decreases by 2-10%). There was an inter-observer variability in image rating across different equipment (kappa value between 0 and 0.3); however, both observers agreed that increasing kVp up to 85-90 kV had no effect on perceived image quality. The results indicate that optimisation strategies should be tailored specifically for each X-ray system since significant performance differences and wide variations in radiation dose exist across various digital radiography systems used in clinical settings. The use of high kVp can be used for dose optimisation in digital pelvis radiography without compromising image diagnostic accuracy.

Evaluation of peri-implant bone defects on cone-beam computed tomography and the diagnostic accuracy of detecting these defects on panoramic images.

Purpose: This study was conducted to identify the typical sites and patterns of peri-implant bone defects on cone-beam computed tomography (CBCT) images, as well as to evaluate the detectability of the identified bone defects on panoramic images. Materials and Methods: The study population included 114 patients with a total of 367 implant fixtures. CBCT images were used to assess the presence or absence of bone defects around each implant fixture at the mesial, distal, buccal, and lingual sites. Based on the number of defect sites, the presentations of the peri-implant bone defects were categorized into 3 patterns: 1 site, 2 or 3 sites, and circumferential bone defects. Two observers independently evaluated the presence or absence of bone defects on panoramic images. The bone defect detection rate on these images was evaluated using receiver operating characteristic analysis. Results: Of the 367 implants studied, 167 (45.5%) had at least 1 site with a confirmed bone defect. The most common type of defect was circumferential, affecting 107 of the 167 implants (64.1%). Implants were most frequently placed in the mandibular molar region. The prevalence of bone defects was greatest in the maxillary premolar and mandibular molar regions. The highest kappa value was associated with the mandibular premolar region. Conclusion: The typical bone defect pattern observed was a circumferential defect surrounding the implant. The detection rate was generally higher in the molar region than in the anterior region. However, the capacity to detect partial bone defects using panoramic imaging was determined to be poor.

Beyond the mouth: Uncovering non-secretory multiple myeloma through oral symptoms.

Non-secretory multiple myeloma (NSMM) is a rare cancer of plasma cells characterized by the absence of detectable monoclonal M protein in the blood or urine. A 57-year-old woman presented with mandibular pain but without intraoral swelling. Imaging studies revealed multiple osteolytic lesions in her mandible and pronounced root resorption of the left mandibular second molar. Biopsy results showed atypical plasmacytoid cells positive for anti-kappa, CD138, MUM1, and CD79a antibodies, but negative for anti-lambda and CD20. These results were indicative of a malignant plasma cell neoplasm. No abnormalities were revealed by free light chain assay or by serum or urine protein electrophoresis, leading to a diagnosis of NSMM. The patient began chemotherapy in conjunction with bisphosphonate therapy and achieved remission following treatment. This case underscores the critical role of dentists in the early detection and prevention of NSMM complications, as the disease can initially present in the oral cavity.

Congenital Lung Malformations: A Pictorial Review of Imaging Findings and a Practical Guide for Diagnosis.

The term congenital lung malformation (CLM) is used to describe a wide range of pathological conditions with different imaging and clinical manifestations. These anomalies stem from abnormal embryological lung development, potentially occurring across various stages of prenatal life. Their natural history can be variable, presenting in a wide range of severity levels and encompassing asymptomatic individuals who remain so until adulthood, as well as those who experience respiratory distress in the neonatal period. Through the PubMed database, we performed an extensive review of the literature in the fields of congenital lung abnormalities, including their diagnostic approach and findings. From our RIS-PACS database, we have selected cases with a final diagnosis of congenital lung malformation. Different diagnostic approaches have been selected, including clinical cases studied using plain radiograph, CT scan, prenatal ultrasound, and MR images. The most encountered anomalies can be classified into three categories: bronchopulmonary anomalies (congenital pulmonary airway malformations (CPAMs), congenital lobar hyperinflation, bronchial atresia, and bronchogenic cysts), vascular anomalies (arteriovenous malformation), and combined lung and vascular anomalies (scimitar syndrome and bronchopulmonary sequestration). CLM causes significant morbidity and mortality; therefore, the recognition of these abnormalities is necessary for optimal prenatal counseling and early peri- and postnatal management. This pictorial review aims to report relevant imaging findings in order to offer some clues for differential diagnosis both for radiologists and pediatric consultants.

A Deep Learning Approach to Automatic Tooth Caries Segmentation in Panoramic Radiographs of Children in Primary Dentition, Mixed Dentition, and Permanent Dentition.

OBJECTIVES: The purpose of this study was to evaluate the effectiveness of dental caries segmentation on the panoramic radiographs taken from children in primary dentition, mixed dentition, and permanent dentition with Artificial Intelligence (AI) models developed using the deep learning method. METHODS: This study used 6075 panoramic radiographs taken from children aged between 4 and 14 to develop the AI model. The radiographs included in the study were divided into three groups: primary dentition (n: 1857), mixed dentition (n: 1406), and permanent dentition (n: 2812). The U-Net model implemented with PyTorch library was used for the segmentation of caries lesions. A confusion matrix was used to evaluate model performance. RESULTS: In the primary dentition group, the sensitivity, precision, and F1 scores calculated using the confusion matrix were found to be 0.8525, 0.9128, and 0.8816, respectively. In the mixed dentition group, the sensitivity, precision, and F1 scores calculated using the confusion matrix were found to be 0.7377, 0.9192, and 0.8185, respectively. In the permanent dentition group, the sensitivity, precision, and F1 scores calculated using the confusion matrix were found to be 0.8271, 0.9125, and 0.8677, respectively. In the total group including primary, mixed, and permanent dentition, the sensitivity, precision, and F1 scores calculated using the confusion matrix were 0.8269, 0.9123, and 0.8675, respectively. CONCLUSIONS: Deep learning-based AI models are promising tools for the detection and diagnosis of caries in panoramic radiographs taken from children with different dentition.

Evaluation of the Tibial Plateau-Patella Angle (TPPA) in Dogs.

Estimating a dog's patellar position involves various methods, which categorize it as norma, alta (high), or baja (low). However, they require various calculations. We aimed to evaluate the clinical applicability of a new method, the tibial plateau-patella angle (TPPA). This could aid in planning patella luxation surgery, estimating the patella position after TPLO and various osteotomies. We conducted a two-step study: first, on 15 stifles without pathologies from nine canine cadavers, and second, using 100 patient X-rays from the archive. Three stifle angle positions (45 ± 5°, 90 ± 5°, and 135 ± 5°) and three weight groups (S, M, and L) were evaluated in the first part of this study. Based on these results, the second part of this study was conducted using 100 pathology-free radiographs at the optimal stifle angle (90 ± 5°) from the archive. All radiographs were measured by three observers with varying levels of experience. Our results indicate that the stifle angle significantly impacted the TPPA, whereby lower values were detected with higher stifle angles, which remained consistent within the weight groups. High inter- and intra-observer agreement was achieved. The physiological TPPA values ranged from 26.7° to 48.8°, remaining consistent within the various weight groups. Observer 3 in Group S exhibited a 20% (insignificant) deviation, possibly due to challenges in determining the caudal point of the tibial plateau. In contrast with humans, TPPA values in dogs are negatively correlated with stifle angles, independent of weight. Our reliable and reproducible protocol suggests the potential benefits of training on small-breed dogs stifles.

Communities of practice: An alternative approach to bridging the theory-practice gap in radiography?

OBJECTIVES: There is an increasing need to engage with evidence-based practice (EBP) and continuing professional development (CPD) to effectively respond to the current healthcare demands and challenges. This review critically synthesises key knowledge diffusion and implementation theories, with particular emphasis on Communities of Practice (CoPs), a theory as yet unexplored in radiography practice. KEY FINDINGS: Prominent theories including implementation science, translational science and knowledge diffusion theories have previously been proposed to bridge the theory-practice gap. However, the radiography profession is a fast-paced, complex and a highly regulated profession which makes the application of rigid theories more challenging. CoPs, which have their origins in Social Learning Theory, represents a potentially more viable approach to bridging the theory-practice gap. CONCLUSION: Cultivating and maintaining CoPs is a more practical approach to improve knowledge dissemination, EBP and CPD, allowing radiographers in practice to share knowledge, best practices, and experiences out with an organisational hierarchy. The collective pool of knowledge, and history created may contribute to further establishing the radiography profession and the radiographer identity as the CoPs connect, expand, and advance over time. IMPLICATIONS FOR PRACTICE: CoPs may be cultivated and further investigated in radiography practice to improve knowledge dissemination, EBP and CPD, with the ultimate aim of improving individual and organisational performance in radiography practices.

The effect of non-immersive virtual reality radiographic positioning simulation on first-year radiography students' image evaluation performance.

INTRODUCTION: Optimal radiographic image quality is critical because it affects the accuracy of the reporter's interpretation. Radiographers have an ethical obligation to obtain quality diagnostic images while protecting patients from unnecessary radiation, including minimizing rejected and repeated images. Repeated imaging due to positioning errors have increased in recent years. METHODS: This study evaluated the effectiveness of non-immersive virtual reality (VR) simulation on first-year students' evaluation of positioning errors on resultant knee and lumbar spine images. Crossover intervention design was used to deliver radiographic image evaluation instruction through traditional lecture and guided simulation using non-immersive VR to 33 first-year radiography students at a single academic institution located across four geographic program locations. Pre- and post-test knowledge assessments examined participants' ability to recognize positioning errors on multiple-choice and essay questions. RESULTS: Raw mean scores increased on multiple choice questions across the entire cohort for the knee (M = 0.82, SD = 3.38) and lumbar spine (M = 2.91, SD = 3.69) but there was no significant difference in performance by instructional method (p = 0.60). Essay questions reported very minimal to no raw mean score increases for the knee (M = 0.27, SD = 2.78) and lumbar spine (M = 0.00, SD = 2.55), with no significant difference in performance by instructional method (p = 0.72). CONCLUSION: Guided simulation instruction was shown to be as effective as traditional lecture. Results also suggest that novice learners better recognize image evaluation errors and corrections from a list of options but have not yet achieved the level of competence needed to independently evaluate radiographic images for diagnostic criteria. IMPLICATIONS FOR PRACTICE: Non-immersive VR simulation is an effective tool for image evaluation instruction. VR increases access to authentic image evaluation practice by providing a simulated resultant image based off the students' applied positioning skills.

Research designs of publications in radiography professional journals - A modified bibliometric analysis.

INTRODUCTION: Evidence based practice relies on availability of research evidence mostly through peer-reviewed journal publications. No consensus currently exists on the best hierarchy of research evidence, often categorised by the adopted research designs. Analysing the prevalent research designs in radiography professional journals is one vital step in considering an evidence hierarchy specific to the radiography profession and this forms the aim of this study. METHODS: Bibliometric data of publications in three Radiography professional journals within a 10-year period were extracted. The Digital Object Identifier were used to locate papers on publishers' websites and obtain relevant data for analysis. Descriptive analysis using frequencies and percentages were used to represent data while Chi-square was used to analyse relationship between categorical variables. RESULTS: 1830 articles met the pre-set inclusion criteria. Quantitative descriptive studies were the most published design (26.6%) followed by non-RCT experimental studies (18.7%), while Randomised Controlled Trials (RCT) were the least published (1.0%). Systematic reviews (42.9%) showed the highest average percentage increase within the 10-year period, however RCTs showed no net increase. Single-centre studies predominated among experimental studies (RCT = 88.9%; Non-RCT = 95%). Author collaboration across all study designs was notable, with RCTs showing the most (100%). Quantitative and qualitative studies comparatively had similar number of citations when publication numbers were matched. Quantitative descriptive studies had the highest cumulative citations while RCTs had the least. CONCLUSION: There is a case to advocate for more study designs towards the peak of evidence hierarchies such as systematic reviews and RCT. Radiography research should be primarily designed to answer pertinent questions and improve the validity of the profession's evidence base. IMPLICATION FOR PRACTICE: The evidence presented can encourage the adoption of the research designs that enhances radiography profession's evidence base.

Perspectives on diagnostic radiographers' motivation for becoming researchers: A qualitative focus group study.

INTRODUCTION: This paper presents motivational factors to engage, start a research project and pursue a research career. The study aimed to investigate radiographer's motivation for engaging in research. METHODS: Eight radiographers from Denmark with experience in research were interviewed in a 2-h focus group interview in October 2023. This qualitative approach was selected to allow the participants to discuss their opinions and values. The discussions were audio recorded and transcribed before the thematic analysis was performed. RESULTS: The analysis revealed six main themes: the importance of radiographic research, the importance of radiographers' participation in research, research radiographers' motivation, funding and participation in research projects, demotivation and difficulties, and facilitating radiographic research in the future. CONCLUSION: The participants were motivated by different factors. The participants found both research in radiography and radiographers' participation in research-related activities important, although they found lack of support from managers, funding, and time to be demotivational factors. IMPLICATION FOR PRACTICE: This study contributes to the limited literature on motivational factors for becoming a researcher within radiography.

Chest CT Imaging Provides More Information Than Chest Radiography Alone in Determining Extent of Physiologic Impairment in Pulmonary Sarcoidosis.

BACKGROUND: Sarcoidosis staging primarily has relied on the Scadding chest radiographic system, although chest CT imaging is finding increased clinical use. RESEARCH QUESTION: Whether standardized chest CT scan assessment provides additional understanding of lung function beyond Scadding stage and demographics is unknown and the focus of this study. STUDY DESIGN AND METHODS: We used the National Heart, Lung, and Blood Institute study Genomics Research in Alpha-1 Antitrypsin Deficiency and Sarcoidosis cases of sarcoidosis (n = 351) with Scadding stage and chest CT scans obtained in a standardized manner. One chest radiologist scored all CT scans with a visual scoring system, with a subset read by another chest radiologist. We compared demographic features, Scadding stage, and CT scan findings and the correlation between these measures. Associations between spirometry results and Dlco, CT scan findings, and Scadding stage were determined using regression analysis (n = 318). Agreement between readers was evaluated using Cohen's κ value. RESULTS: CT scan features were inconsistent with Scadding stage in approximately 40% of cases. Most CT scan features assessed on visual scoring were associated negatively with lung function. Associations persisted for FEV1 and Dlco when adjusting for Scadding stage, although some CT scan feature associations with FVC became insignificant. Scadding stage was associated primarily with FEV1, and inclusion of CT scan features reduced significance in association between Scadding stage and lung function. Multivariable regression modeling to identify radiologic measures explaining lung function included Scadding stage for FEV1 and FEV1 to FVC ratio (P < .05) and marginally for Dlco (P < .15). Combinations of CT scan measures accounted for Scadding stage for FVC. Correlations among Scadding stage and CT scan features were noted. Agreement between readers was poor to moderate for presence or absence of CT scan features and poor for degree and location of abnormality. INTERPRETATION: CT scan features explained additional variability in lung function beyond Scadding stage, with some CT scan features obviating the associations between lung function and Scadding stage. Whether CT scan features, phenotypes, or endotypes could be useful for managing patients with sarcoidosis needs more study.

Can silver nanoparticles stabilized by Fenugreek (Trigonella foenm -graecum) improve tibial bone defects repair in rabbits? A preliminary study.

Background: A fracture is considered a medical emergency leading to considerable complications. Aim: This study aimed to describe the accelerating action of Ag-NPs-FG on fracture healing in rabbits. Methods: Silver NPs (AgNPs) were reduced with fenugreek (FG), loaded into a starch gel base, and investigated for their morphology, size, and charge. Four equal groups were randomly formed of 40 adult male rabbits. A 3.5 mm diameter bone defect was created at the proximal metaphysis of the right tibia in each rabbit. Groups 1-4 were injected with placebo saline, AgNPs-FG, plain gel, and FG-gel at the bone defect zone, respectively. The healing was assessed for 8 weeks postoperatively based on the radiographic, bone turnover markers, and histopathological examinations. Results: The AgNPs-FG was obtained as a faint reddish color, spherical in shape, with an absorbance of 423 nm, a size of 118.0 ± 1.7 nm, and a surface charge of -7.8 ± 0.518 mV. The prepared AgNPs-FG hydrogel was clear, translucent, and homogenous. The pH values were 6.55-6.5 ± 0.2, the viscosity of 4,000 and 1,875 cPs, and spreadability of 1.6 ± 0.14 and 2.0 ± 0.15 for both FG and AgNPs-FG hydrogel, respectively. The radiographic union scale was significantly (p < 0.05) improved in group 2 with a significant (p < 0.05) increase in bone turnover markers was found in comparison to other treated groups. Histopathological examination revealed the formation of mature bone on the 28th postoperative day in groups 2 and 4. Conclusion: Colloidal nano-formulation of AgNPs-FG loaded hydrogel could be a promising formulation to accelerate rabbits' tibial bone healing process.

Imaging of Rheumatic Diseases Affecting the Lower Limb.

Imaging methods capable of detecting inflammation, such as MR imaging and ultrasound, are of paramount importance in rheumatic disease management, not only for diagnostic purposes but also for monitoring disease activity and treatment response. However, more advanced stages of arthritis, characterized by findings of cumulative structural damage, have traditionally been accomplished by radiographs and computed tomography. The purpose of this review is to provide an overview of imaging of some of the most prevalent inflammatory rheumatic diseases affecting the lower limb (osteoarthritis, rheumatoid arthritis, and gout) and up-to-date recommendations regarding imaging diagnostic workup.

Enablers and barriers to delivering person centred dementia care: Perceptions and experiences of diagnostic and therapeutic radiography practitioners.

INTRODUCTION: There is a lack of evidence about the experiences of radiographers providing care to people living with dementia (PLWD). This study explored the perceptions and experiences of radiography practitioners when delivering person-centred dementia care (PCDC) in both diagnostic imaging and radiotherapy departments. METHODS: A two-phase qualitative multi-method study was conducted. For phase 1, fifteen diagnostic and two therapeutic radiography practitioners from across the UK participated with online focus group discussions. For phase 2, four key stakeholders involved with the development of the UK Society of College of Radiographers Caring for People with Dementia practice guidelines for diagnostic and therapeutic radiography practitioners took part with individual semi-structured interviews. RESULTS: Participants from both phases identified enablers and barriers to providing person-centred care to individuals living with dementia. Three themes were identified that were linked to (1) Time and workload pressures in delivering person-centred dementia care, (2) Workplace practice and norms, and (3) Areas for improvement in delivering person-centred dementia care. DISCUSSION: Delivering PCDC can be challenging in practice. This is often due to workplace cultures where time and resources linked to productivity and waiting lists are the norms and impact on the delivery of PCDC. Leaders and managers of departments were thought to not always value a culture of PCDC but were seen as key influencers in supporting change and impact in delivering PCDC. Radiography practitioners were not always aware that a patient had dementia prior to their attendance in the department making it difficult to prepare ahead of appointments. Care partners were identified as having the potential to help alleviate some challenges radiographers faced. Findings also suggest a need for more education and training linked to dementia awareness. Further research is warranted in this area.

RADIOGRAPHIC EVALUATION OF CONSERVATIVE TREATMENT OF DISTAL RADIUS FRACTURES.

Objective: This article aims to evaluate the evolution of radio-graphic parameters (radial tilt, volar tilt, and radial height) of distal radius fractures in patients indicated for conservative treatment at three different times: date of diagnosis, first outpatient visit within 2 weeks after closed reduction, and last outpatient visit. Methods: We included 84 patients seen at the emergency department of Hospital Municipal Odilon Behrens, with a diagnosis of distal radius fracture and an indication for conservative treatment. We considered only those patients who had serial radiographs taken at least three different times (n=69) in this analysis. Results: There was an improvement in radiographic parameters of volar tilt after closed reduction and immobilization, which was maintained until the last outpatient visit. Radial inclination and radial height showed increased values from the first to the second radiographic evaluation and both values had regression when comparing the second to the third (last) evaluation. Conclusion: Universal classification stable fractures tend to evolve well with conservative therapy. Level of Evidence II; Development of Diagnostic Criteria in Consecutive Patients (with Gold Standard of Reference Applied).

Objetivo: O objetivo deste artigo foi avaliar a evolução dos parâmetros radiográficos (inclinação radial, inclinação volar e altura radial) das fraturas da extremidade distal do rádio em pacientes com indicação de tratamento conservador em três momentos diferentes: data do diagnóstico, primeira consulta ambulatorial dentro de. semanas após a redução fechada e última consulta ambulatorial. Métodos: Incluímos 84 pacientes atendidos no departamento de emergência do Hospital Municipal Odilon Behrens, com diagnóstico de fratura distal do rádio e indicação de. conservador. Consideramos nesta análise apenas os pacientes que tiveram radiografias seriadas realizadas pelo menos três vezes diferentes (n=69). Resultados: Houve uma melhora nos parâmetros radiográficos da inclinação volar após a redução fechada e a imobilização, que foi mantida até a última consulta ambulatorial. A inclinação radial e a altura radial apresentaram valores aumentados da primeira para a segunda avaliação radiográfica e ambos os valores tiveram regressão quando comparados da segunda para a terceira (última) avaliação. Conclusão: As fraturas estáveis de classificação universal tendem a evoluir bem com a terapia conservadora. Nível de Evidência II; Desenvolvimento de critérios diagnósticos em pacientes consecutivos (com aplicação de referência padrão ouro).

SHORTENING OF CLAVICLE FRACTURES: PHYSICAL VERSUS IMAGE EXAMINATIONS.

Objective: Determine the reliability of three different methods of evaluating bone shortening in displaced midshaft clavicle fractures (DCMF). Method: A cross-sectional analytical study evaluated bone shortening by metric tape (MT), radiography (X-ray), and computed tomography (CT). Twenty-six men had been evaluated and used clavícula not broken as control. The collection of data was of the blind type for three specialists. Differences and reliability were analyzed with the Friedman and Kappa tests and validated with the T-test (CI: 95%; significance index p<0.05; Software "R" version 3.2.2). Results: The MT measurements (control) showed abnormal distribution and significant statistical difference concerning the imaging tests (p=0.000008). There was a similarity between X-ray and CT and Kappa agreement of 0.65. The fractured clavicles presented similar measurements between the three methods (p=0.059), and the T-tests proved that the similarity was caused by chance or possible measurement errors. Conclusion: Measurement by metric tape showed a tendency to overestimate bone shortening. The CT showed more reliable results for the diagnosis; however, the X-ray was sufficient for decision-making by surgeons, and therefore, it is not possible to rule out the importance of this resource for DCMF. Level of Evidence IV; Case-Control Study.

Objetivo: Determinar a confiabilidade de três diferentes métodos de avaliação do encurtamento ósseo em fraturas deslocadas do eixo médio da clavícula (FDEMC). Método: Estudo analítico transversal que avaliou o encurtamento ósseo por fita métrica (FM), radiografia (X-Ray) e tomografia computadorizada (TC). Foram avaliados 26 homens utilizando a clavícula não fraturada como controle. A coleta de dados foi do tipo cega por três especialistas. As diferenças e a confiabilidade foram analisadas com os testes de Friedman e Kappa e validados com o teste T (IC:95%; índice de significância p<0,05; Software "R" versão 3.2.2). Resultados: As medidas de FM (controle), apresentaram distribuição anormal e diferença estatísfica significativa em relação aos exames de imagem (p=0,000008). Houve semelhança entre radiografia e TC, concordância Kappa 0,65. As clavículas fraturadas apresentaram medidas semelhantes entre os três métodos (p=0,059) e os testes-T comprovaram que a semelhança foi provocada casualmente ou possíveis erros de medição. Conclusão: A medição por fita métrica apresentou tendência em superestimação do encurtamento ósseo. A TC apresentou resultados mais confiáveis para o diagnóstico, contudo, a radiografia foi suficiente para tomada de decisão dos cirurgiões e por isso, não é possível descartar a importância deste recurso para FDEMC. Nível de Evidência IV; Estudo Caso Controle.
