“…For the first experiment using minor added fractures, the 70 added fractures were presented on digital radiographs of the foot [6], ankle [4], tibia/fibula [7], knee [5], pelvis [3], chest [3], shoulder [10], arm [5], elbow [4], wrist [11], and hand/fingers [12]. The digital radiographs that were used in place of these examinations for the non-SOS condition had the same distribution of body parts.…”

“…The digital radiographs that were used in place of these examinations for the non-SOS condition had the same distribution of body parts. For the second and third experiments using major added fractures, the 55 added fractures were presented on computed tomography of the cervical spine [48] or pelvis [7], and 15 of the added fractures were presented on digital radiography of the cervical spine [6], pelvis [7], chest [1] or hand [1].…”

“…Major added fractures of our second experiment involved potential major morbidity (such as a cervical spine fracture), usually involving computed tomography (CT). Multidetector CT has revolutionized the diagnostic evaluation of trauma and emergency room patients (6)(7)(8)(9)(10), particularly for spinal injury. Patients with life threatening spinal or pelvic injuries are usually examined using multidetector CT rather than with radiography.…”

Satisfaction of Search in Multitrauma Patients: Severity of Detected Fractures

Purpose-Satisfaction of search (SOS) occurs when an abnormality is missed because another abnormality has been detected. This research studied whether the severity of a detected fracture determines whether subsequent fractures are overlooked.Materials and Methods-Each of seventy simulated multi-trauma patients presented examinations of three anatomic areas. Readers evaluated each patient under two experimental conditions: when the images of the first anatomic area included a fracture (the SOS condition), and when it did not (the control condition). The SOS effect was measured on detection accuracy for subtle test fractures presented on examinations of the second and third anatomic areas. In an experiment with twelve radiology readers, the initial SOS radiographs showed non-displaced fractures of extremities, fractures associated with low morbidity. In another experiment with twelve different radiology readers, the initial examination, usually a CT, showed cervical and pelvic fractures of the type associated with high morbidity. Because of their more direct role in patient care, the experiment using high morbidity SOS fractures was repeated with seventeen orthopedic readers.Results-Detection of subtle test fractures was substantially reduced when fractures of low morbidity were added (p<0.01). No similar SOS effect was observed in either experiment in which added fractures were associated with high morbidity. Conclusion-The satisfaction of search effect in skeletal radiology was replicated, essentially doubling the evidence for SOS in musculoskeletal radiology, and providing an essential contrast to the absence of SOS from high morbidity fractures.

Object Upper cervical spine injuries in the pediatric age group have been recognized as extremely unstable from ligamentous disruption and as potentially lethal. Few measurement norms have been published for the pediatric upper cervical spine to help diagnose this pathological state. Instead, adult measurement techniques and results are usually applied inappropriately to children. The authors propose using high-resolution reconstructed CT scans to define a range of normal for a collection of selected upper cervical spine measurements in the pediatric age group. Methods Sagittal and coronal reformatted images were obtained from thin axial CT scans obtained in 42 children (< 18 years) in a 2-month period. There were 25 boys and 17 girls. The mean age was 100.9 months (range 1–214 months). Six CT scans were obtained for nontrauma indications, and 36 were obtained as part of a trauma protocol and later cleared for cervical spine injury. Six straightforward and direct linear distances—basion-dental interval (BDI); atlantodental interval (ADI); posterior atlantodental interval (PADI); right and left lateral mass interval (LMI); right and left craniocervical interval (CCI); and prevertebral soft-tissue thickness at C-2—that minimized logistical and technical distortions were measured and recorded. Statistical analysis including interobserver agreement, age stratification, and sex differences was performed for each of the 6 measurements. Results The mean ADI was 2.25 ± 0.24 mm (± SD), the mean PADI was 18.3 ± 0.07 mm, the mean BDI was 7.28 ± 0.10 mm, and the mean prevertebral soft tissue width at C-2 was 4.45 ± 0.43 mm. The overall mean CCI was 2.38 ± 0.44 mm, and the overall mean LMI was 2.91 ± 0.49 mm. Linear regression analysis demonstrated statistically significant age effects for PADI (increased 0.02 mm/month), BDI (decreased 0.02 mm/month), and CCI (decreased 0.01 mm/month). Similarly significant effects were found for sex; females demonstrated on average a smaller CCI by 0.26 mm and a smaller PADI by 2.12 mm. Moderate to high interrater reliability was demonstrated across all parameters. Conclusions Age-dependent and age-independent normal CT measurements of the upper cervical spine will help to differentiate physiological and pathological states in children. The BDI appears to change significantly with age but not sex; on the other hand, the LMI and ADI appear to be age-independent measures. This preliminary study suggests acceptable levels of interrater reliability, and further expanded study will aim to validate these measurements to produce a profile of normal upper cervical spine measurements in children.

AbstrakStudi ini bertujuan menilai peranan CT pada cedera saluran aerodigestif bagian atas. Dua Abstract This study was aimed to assess the role of CT in upper aerodigestive tract injuries. Twenty six patients presenting with upper aerodigestive tract injury were examined by CT. Nineteen patients had blunt trauma to the neck while seven had penetrating injury. Most of the patients presented soon after injury. Symptoms included respiratory distress (14), neck tenderness (18), hoarseness (7), haemoptysis (2) and odynophagia (3). Soft tissue injuries were seen in 8 patients
