Introduction This systematic review investigates which image appearances are most common when diagnosing lower limb stress fractures using ultrasound imaging, with the aim of outlining an image critique guideline for operators to support confident diagnoses. Method A comprehensive literature search of medical databases and handsearching was undertaken to identify relevant studies. All studies were critically examined for quality using the CASP critical appraisal tool. Results from eight studies were combined and interpreted using a narrative synthesis. Findings A clear outline of common stress fracture appearances using ultrasound were identified in a combined total of 119 participants. Each finding was ranked according to its popularity. Periosteal thickening (78/119) and cortical disruption/irregularity (83/119) were noted in all eight studies. Hypervascularity of the periosteum visualised by colour Doppler imaging (66/119) was reported in six of the eight studies. Soft tissue hypervascularity (13/119), bony callus formation (5/119) and cortical break (22/119) were seen in three studies. Conclusions Based on the findings, we offer a guideline of the most significant preliminary image findings to be utilised by operators when examining athletes suspected of having lower limb stress fractures. The results show a gap in research for evaluating changes in appearance depending on the injury severity. Further research into distinguishing stress fractures from pathological involvement may in future reduce reliance on plain film radiography.

Genial Tubercle

Genial tubercle fracture (GTF) is rare and represents a diagnostic challenge as plain film radiography often fails to identify the fractured segment. Traumatic avulsion of the genial tubercle in conjunction with mandibular symphysis fracture may lead to posterior displacement of the tongue with the potential for airway compromise and difficulty in speech and swallowing due to loss of tongue anterior suspension. Fine cut computed tomography (CT) scan is required to confirm the diagnosis and assist further management. To our knowledge, all published cases of surgical intervention in the management of avulsed genial tubercle combined with fracture of the mandibular symphysis used an extraoral approach via submental skin incision to expose the fractured segment. To the authors’ knowledge, this is the first report to describe a transoral approach in the surgical management of GTF associated with a mandibular fracture.

Dislocation Of The Patella

Pediatric osteochondral fracture dislocation of the patella is sometimes difficult to diagnose on the basis of physical examination or plain film radiography. Magnetic resonance imaging plays an important role in its early diagnosis, and early treatment can prevent damage to the articular cartilage as well as decrease the dislocation rate. Currently, many treatment choices have been reported with good results, but there is no consensus on which treatment option may lead to the best outcome. Herein, we describe the case of a 14-year-old girl with neglected osteochondral fracture dislocation of the patella. The outcome was optimal on the basis of a 2-year postoperative follow-up; thus, we believe that fixation with headless screws is a simple and effective method if the fracture fragment is large enough.

AbstractPurposeTo evaluate the images obtained by CT in diagnosis and treatment plan of teeth in the maxillary sinus.MethodsTwelve patients with teeth in the maxillary sinus were studied by plain film radiography(PFR) and by CT with a dental software programme, which displays multiple panoramic and cross-sectional views of the mandible and maxilla. The three-dimensional morphology of the tooth, its inclination, proximity to the sinus wall, surgical planning and prediction of prognosis and complications were estimated on both PFR and on CT scans and scored.ResultsThe radiographical features interpreted from PFR were fair or poorly diagnosed whereas CT provided excellent features. The surgical approach of choice was based on CT interpretation.ConclusionCT is useful for diagnosis and treatment planning of teeth in the maxillary antrum.

Cross Sectional Imaging

Plain film radiography is often the first imaging modality employed in the assessment of patients with a rheumatological condition. More recently this has been superseded by cross-sectional imaging, in particular ultrasound and MRI, which have improved sensitivity in detection of early disease when compared with plain film imaging. However, there remains a role for conventional radiography in both the initial diagnosis and monitoring of disease progression. A standard approach to assessing radiographs in the context of arthropathy is usually employed by radiologists; by following this structured review a diagnosis or narrow differential may be reached on plain film imaging alone. Plain film radiograph findings of the most common rheumatological disorders are covered in detail in this chapter including osteoarthritis, the inflammatory arthritides, and crystal arthropathy. Findings in the connective tissue disorders are then covered, followed by less commonly encountered conditions such as SAPHO, neuropathic arthropathy, and haemochromotosis.

Plain Film Radiography

Cone beam computed tomography (CBCT) can be a useful adjunct to conventional plain film radiography, but its use must be carefully justified as the radiation dose is generally higher. Factors affecting the dose include the field of view (FOV) size, the exposure factors, the angle of rotation and voxel size. Once justified, the exposure should be fully optimised to ensure the dose to the patient is kept as low as possible while ensuring there is no reduction in the diagnostic yield. The European Commission (EC) and the Faculty of General Dental Practice (FGDP)(UK) have published selection criteria on the use of CBCT in dentistry. This article provides an overview of CBCT and summarises the latest guidance on selection criteria relevant to the general dental practitioner.

Objective This study aims to define a reliable protocol for radiographic identification of placement and tip foldover of newly designed precurved and straight electrodes. Study Design Prospective imaging study. Setting Academic institution. Methods Three models of cochlear implants (Cochlear, MED-EL, and Advanced Bionics) were inserted into fresh cadaveric specimens (n = 2) in 3 configurations (normal positioning in the scala tympani, intracochlear tip foldover, and placement into the vestibular system) for a total of 9 implant scenarios. Specimens were imaged with plain radiography in Stenvers projection, as well as by high-resolution computed tomography. Results Electrode placement and presence or absence of electrode tip foldover were easily identified in all 9 scenarios on plain radiography based on the described technique. Each was confirmed with high-resolution computed tomography. Plain film temporal bone images of new electrode designs with proper and improper placement are provided for reference. Conclusion A defined protocol for intraoperative plain film radiography allowed for reliable imaging of 3 newly designed cochlear implant electrodes and immediate identification of extracochlear placement and tip foldover. Findings may be used for intraoperative confirmation of electrode array placement.
