Ultrasound evaluation of elbow fractures in children

Abstract

Typical elbow fractures in children could also be visualized by US. A positive fat pad sign, in particular, serves as a strong indicator for elbow joint fractures and can be identified very sensitively by US. We confirm US as a valuable primary screening tool for elbow injuries in children. In the absence of US signs of fracture and in sonographically confirmed non-displaced fractures, standard X-rays are dispensable, thereby minimizing the X-ray burden in children without loss of diagnostic safety.

Screw-Bone Implant Loosening: Complication, Cause and Assessment

“…The ultrasound diagnostic have been discovered to have the sensitivity of 97.9% with a specificity of 95% for the scan of an elbow fracture and have the accuracy to estimate the fracture displacement adequately by Eckert et al [57]. This proves that ultrasonic imaging is an excellent alternative compared to radiography which when used periodically can cause harm to human due to the radiation emission [51], [57].…”

The detection of fracture the sensitivity of ultrasound is 92.9% and a specificity of 99.5% which is comparable to the detection using X-ray that have the sensitivity of 93.2 and specificity of 99.8% have been reported by Moritz et al [58].…”

Sonographische Frakturdiagnostik

“…Da kindliches Knochengewebe jedoch deutlich strahlensensibler als das des Erwachsenenalters ist, sollte jede unnötige ionisierende Strahlung vermieden werden. Zahlreiche Publikationen belegen mittlerweile den sinnvollen Einsatz der Sonographie im Rahmen der primären Frakturdiagnostik, und systematische Untersuchungen mit direktem Vergleich zur Röntgendiagnostik zeigen, dass die Sonographie bei bestimmten Frakturentitäten das Röntgen ergänzen oder sogar ersetzen kann [1][2][3][4][5][6]. Bei gleicher diagnostischer Qualität kann so die Zahl unnötiger Röntgenuntersuchungen reduziert werden.…”

Indikationen zur sonographischen Frakturdiagnostik von Frakturen im Wachstumsalter

“…Bei Nachweis von Flüssigkeit (SOFA+) wird die Rönt-gendiagnostik in 2 Ebenen durchgeführt. Mit dieser Methode lassen sich etwa 70 % der Röntgenbilder vermeiden [12].…”

“…Die Sensitivität der Methode im Vergleich zur Röntgendiagnostik beträgt 97,9 %, die Spezifität 95 %, der positive Vorhersagewert 0,95, der negative Vorhersagewert 0,98 [12].…”
