A Case Report of Lateral Subtalar Dislocation: Emergency Medicine Assessment, Management and Disposition
DOI: https://doi.org/10.21980/J8SS8PIn a lateral subtalar dislocation, the navicular bone (red bone in 3D anatomy image) and the calcaneus (yellow bone in 3D anatomy image) dislocate laterally in relation to the talus (lavender bone in 3D anatomy image). Plain film oblique and lateral X-rays demonstrate the initial dislocation (talus in red, navicular in blue). It is clear in the initial lateral view that there is loss of the talar/navicular articulation (noted by red arrow). The anterior-posterior x-ray is more challenging to discern the anatomy; however, the talus (red dot) is laterally displaced in comparison to the navicular (blue dot).
A Case Report of Dermatographia
DOI: https://doi.org/10.21980/J8P05PPhysical examination was unremarkable except for the urticaria on the right aside of her abdomen (white arrow) with overlying excoriations (stars). Of note, there were no burrows, papules or vesicles in the typical locations including the webs of the fingers, wrists, axillae, areolae, or genitalia. Examination of the linear dermatographia clearly revealed superficial wheals, versus underlying serpiginous lesions.
A Case Report of Acute Compartment Syndrome
DOI: https://doi.org/10.21980/J87061Inspection of the extremity revealed significant swelling with dark discoloration and multiple bullae (pre-operative photograph). Furthermore, notable swelling of the right foot was noted, which felt cold to palpation. Radiographs of pelvis, bilateral knees, tibia, fibula, and feet demonstrated no fractures or dislocations. The bilateral tibia and fibula X-ray revealed soft tissue swelling in the proximal legs, particularly evident in the right leg's AP view, which also showed numerous ovoid radiodensities in the anterior compartment, likely related to soft tissue injury. Post operative images are also provided demonstrating the patients’ four compartment fasciotomies which were loosely closed using staples.
The Clue is in the Eyes. A Case Report of Internuclear Ophthalmoplegia
DOI: https://doi.org/10.21980/J8DP9MThere was no appreciable esotropia or exotropia noted on straight gaze (yellow arrows). On extraocular muscle examination, patient was noted to have a complete left medial rectus palsy consistent with a left internuclear ophthalmoplegia (red arrow). This was evidence by both eyes easily gazing left (green arrows); however, with rightward gaze, her left eye failed to gaze past midline (red arrow).
Septic Arthritis of the Acromioclavicular Joint: A Case Report
DOI: https://doi.org/10.21980/J8VP9NMagnetic resonance imaging (MRI) with contrast was obtained of the shoulder and ankle, and results from both scans showed findings consistent with septic arthritis complicated by intraarticular abscesses. The MRI of the patient’s left acromioclavicular joint is shown as both a T1-weighted sequence in sagittal view and T2-weighted sequence in coronal view. The images show effusion (the dark fluid denoted by the red arrow) with an adjacent fluid collection (blue arrow). A T2-weighted MRI in coronal view of the patient’s right ankle showing multiple effusions (green arrows) and a fluid collection along the medial tibial cortex and subcutaneous tissues (yellow arrow).
Case Report of a Child with Colocolic Intussusception with a Primary Lead Point
DOI: https://doi.org/10.21980/J8564QOn the initial ED visit, an abdominal ultrasound (US) was ordered which showed the classic intussusception finding of a target sign (yellow arrow), or concentric rings of telescoped bowel, on the transverse view of the left lower quadrant (LLQ).
Sonographic Retrobulbar Spot Sign in Diagnosis of Central Retinal Artery Occlusion: A Case Report
DOI: https://doi.org/10.21980/J8735PThe bedside ocular ultrasound (B-scan) was significant for small, hyperechoic signal (white arrow) in the distal aspect of the optic nerve, concerning for embolus in the central retinal artery. Subsequent direct fundoscopic exam was significant for a pale macula with cherry red spot (black arrow), consistent with central retinal artery occlusion (CRAO).
A Case Report of Invasive Mucormycosis in a COVID-19 Positive and Newly-Diagnosed Diabetic Patient
DOI: https://doi.org/10.21980/J81M1GOn physical exam, when the patient was asked to try and look to her right, the right eye failed to move laterally/abduct (blue arrow). Additionally, when asked to look straight ahead, the eye was slightly adducted (red arrow). There was a lack of motion of the right eye in abduction when the patient was asked to look to her right (yellow arrow).
