Orthopedic Patients

Radiography and/or ultrasonography are the first imaging modalities for diagnosing orthopedic pathology in equine patients. However, in some cases, cross-sectional imaging is necessary to reach a more accurate diagnosis. Six cases were retrospectively selected from the imaging database of the Faculty of Veterinary Medicine (Ghent University) to illustrate the benefits of computed tomography (CT) in orthopedic patients. In two cases, CT demonstrated osteomyelitis lesions in two young foals, which could not be detected with radiography and ultrasonography. In three cases, CT was performed for surgical planning of fracture repair, and in one case CT demonstrated multiple lesions at the soft tissues and ligamentous insertions in the stifle. In all cases, CT revealed additional findings, which were important for the treatment and prognosis of the patient.

Tomography Imaging

Macrodactyly is a deformity that may progress beyond initial surgical resection. Three-dimensional computed tomography imaging may aid in the surgical planning, given the osseous irregularities that may exist. The objective in revisional surgery of this type is to provide the most functional and cosmetic result. In this case, the hallux was saved when the patient previously had requested an amputation. The case also illustrates that when earlier surgery has been performed, the classic approaches to macrodactyly advocated in the literature may not be feasible. The surgeon must then approach the deformity with some flexibility, and three-dimensional imaging may be a useful tool.

Panfacial Fractures

AbstractThe evaluation and management of a patient with panfacial fractures are multifaceted. Herein, we describe basic facial skeletal anatomy, considerations for airway securing, and common concurrent injuries. Finally, we discuss primary and secondary reconstructions of facial trauma including sequencing of repair, available landmarks, and the utility of intraoperative computed tomography imaging and virtual surgical planning with custom implants.

Eruption disturbances in permanent mandibular first molars (PM1s) are uncommon. This retrospective study aimed to investigate differences in the position of the mandibular canal in relation to PM1s, with or without, eruption disturbances. Panoramic and cross-sectional views were reconstructed from cone-beam computed tomography imaging of children with PM1 eruption disturbances. Distances from the most inferior margin of the mandible to the center of the mandibular canal (M–C) and from the outer margin of the lingual cortex to the center of the mandibular canal (L–C) were measured for normally erupted PM1s (normal group) and for PM1s with eruption disturbances (ED group) and compared using independent t-tests. The mean M–C was significantly shorter in the ED group (4.86 ± 1.07 mm) than in the normal group (6.56 ± 1.06 mm) (p < 0.05). The mean L–C was also significantly shorter in the ED group (2.74 ± 0.74 mm) than in the normal group (3.09 ± 0.71 mm) (p < 0.05). This study demonstrated that the mandibular canal tended to be positioned more inferiorly in relation to PM1s with eruption disturbances than normally erupted PM1s in children. Clinicians should be aware of this positional deviation when managing children with PM1 eruption disturbances.

Congenital hemifacial hyperplasia is a rare developmental disorder of unknown etiology, characterized by a marked unilateral facial asymmetry. It involves the hard (bones and teeth) and soft tissues of the face. We report an interesting case of true hemifacial hyperplasia in a 25-year-old male highlighting the clinical and computed tomography imaging findings.

Abstract Vomiting-induced pneumomediastinum can be a result of barotrauma causing alveolar rupture or Boerhaave’s syndrome. Although a rare cause of secondary pneumomediastinum, Boerhaave’s syndrome allows extravasation of air and fluid due to oesophageal perforation. We report a case of a 20-year-old female who presented with prolonged vomiting during a panic attack. Extensive surgical emphysema and pneumomediastinum were visualised radiologically. A source of oesophageal rupture was not visualised on cross-sectional computed tomography imaging following contrast ingestion. A complication of mediastinitis provided the evidence that this was a case of Boerhaave’s syndrome whereby microscopic perforation of the oesophagus led to secondary pneumomediastinum, rather than vomiting-induced spontaneous pneumomediastinum caused by barotrauma. Recurrent Boerhaave’s syndrome in this case is owed to the patient having previously experienced identical symptoms which spontaneously resolved.
