Radiography of Clavicle Fractures— A Review of the Literature —Do Various Radiographic Views of Clavicle Fractures Affect the Management Plan?

引用

Open Journal of Radiology 2014年第3期4卷 235-240页

作者： Njalalle Baraza Thomas Wood Department of Trauma and Orthopaedics Alexandra Hospital Redditch Worcestershire UK

Introduction: Fractures of the clavicle are common and make up 5% - 10% of all fractures. Treatment options in part depend on the location of the fracture along the bone and degree of displacement. These two parameters are best determined by good quality, standardized radiographs of the clavicle. We reviewed the literature to determine the optimal radiographs of clavicle fractures and their influence on the treatment plan. Methods: A comprehensive search of Medline? database was undertaken with the following search terms and MeSH headings: clavicle, fractures, bone, radiography, and X-ray. We included articles in English published from 1950 to present. We ruled out fractures in children, fracture dislocations, open fractures, those with neurological and vascular injuries and fractures involving the acromioclavicular or sternoclavicular joints. Findings: Of the 821 citations obtained, only four studies proved eligible. In the most pertinent, four orthopaedic surgeons were shown standard views (antero-posterior and 20°cephalic tilt) of 50 clavicle fractures and then additional two views (45°cephalic and caudal tilt), and found that alternative views influenced their decision making, with more surgeons opting for surgical fixation. In a different study, it was shown that orthogonal views of the clavicle increased surgeons’ understanding and improved their treatment of these fractures. The third paper was a case series on clavicle fractures that were missed on the initial antero-posterior radiograph, and the fourth paper postulated that postero-anterior views of the thorax were most accurate in determining length of the clavicle. Conclusion: Studies showing an optimal view for assessment of clavicle fractures with a decision to then progressing to operative fixation are few, but the evidence points towards surgical fixation when alternative views of mid-shaft clavicle fractures are present.

5-year audit of the range and volume of diagnostic radiographic services at the University of Nairobi Dental Hospital

引用

Open Journal of Stomatology 2012年第3期2卷 234-236页

作者： Eunice N. Kihara Florence Opondo Tom J. Ocholla Mark L. Chindia Evelyn Wagaiyu Department of Oral & Maxillofacial Surgery Oral Pathology & Medicine University of Nairobi Nairobi Kenya Department of Periodontology University of Nairobi Nairobi Kenya Radiology Division Department of Oral & Maxillofacial Surgery Oral Pathology & Medicine University of Nairobi Nairobi Kenya

Background: Dental and cranio-maxillofacial diagnostic imaging constitutes an invaluable tool in the accurate diagnosis and management of a diverse range of conditions and diseases that afflict the oral and cranio-maxillofacial region. In order to improve on any existing facility, periodic audit evaluation is paramount. In this way proper and relevant service delivery can be achieved. Objective: To evaluate the range and volume of dental and cranio-maxillofacial diagnostic radiographic services offered at the University of Nairobi Dental Hospital (UNDH) in Kenya over a 5-year period (2006-2010). Methods: Retro-spective survey involving manual examination of patient records at the Division of Dental and cra-nio-maxillofacial Radiology registry of the UNDH. Results: Over the study period, the range of diagnostic radiographic services offered comprised of both intra- and extra- oral examinations. The total volume of radiographs taken was 48,874 among which 41,980 (86%) were intraoral and 6894 (14%) extraoral views. Among the intraoral views, 74% were bitewing, 25% periapical and only 1% were occlusal diagnostic views. The majority (95%) of the extraoral projections consisted of panoramic views and only 5% constituted other techniques. The volume of radiographs was high from January to September while November and December had the lowest number of examination requests. Conclusion: Intraoral radiography was the commonest examination with bitewings having been the majority while the panoramic tomography was the commonest extraoral examination performed.

Radiation Field Preference for Radiographic Anatomical Markers by Radiographers in a University Teaching Hospital in Nigeria

引用

Open Journal of Radiology 2014年第3期4卷 275-278页

作者： Thomas Adejoh Sobechukwu Warric Iwene Onwuzu Flavious Bobuin Nkubli Nwamaka Ikegwuonu Radiology Department Nnamdi Azikiwe University Teaching Hospital Nnewi Nigeria Medical Imaging Unit Department of Medical Centre University of Nigeria Nsukka Nigeria Department of Medical Radiography College of Medical Sciences University of Maiduguri Maiduguri Nigeria

Objective: The work aims to determine the radiographers’ preference between primary and secondary radiation fields for imprinting anatomical markers on radiographs. Methodology: Processed radiographs from the darkroom with evidence of radiographic anatomical markings were selected randomly and reviewed using a viewing box, within a 4-week period. The radiation field in which markers were placed was noted for each radiograph. Faintly-appearing and partly coned- off markers were excluded. Simple statistical tools were used to derive central tendency. Result: 623 radiographs were assessed. 89.0% (n = 555) had markers in the primary radiation field while 11.0% (n = 68) were in the secondary radiation field. 98% (n = 611) of markers did not obstruct essential anatomy while 2% (n = 12) did, but the radiographs were neither repeated nor rejected because of the twin reason of reportability and the need to avoid additional radiation dose to patients. Conclusion: Radiographers in the centre preferred the primary radiation field for marker placement to avoid cone-off, cut-off and illegibility which leads to repeat. This, however, does not offer superior advantage to markers placed in secondary radiation field. It is recommended that marker placement preference should be guided by the need for legibility, aesthetics and avoidance of essential anatomy.
