Beschreibung
Inclusion Criteria:
- Diagnosis of an impending femur fracture requiring prophylactic intramedullary fixation
Impending fracture secondary to a pathologic process, including:

- Ability to provide informed consent
Exclusion Criteria:
- Inability to obtain adequate intraoperative transthoracic echocardiography (TTE) imaging windows for visualization of right-sided cardiac structures
- Inability to tolerate or safely undergo TTE monitoring per anesthesia determination
- Any intraoperative technical limitation preventing reliable echocardiographic data acquisition

Change in Embolic burden as assessed by intraoperative transthoracic echocardiography (TTE)
Zeitfenster: baseline (prior to canal instrumentation), during canal preparation/reaming, during nail insertion, and immediately post-procedure(about 1 to 2 after start of surgery)
|
Embolic burden is defined as the presence, frequency, and severity (graded semi-quantitatively) of echogenic embolic events within the right atrium, right ventricle, and pulmonary artery outflow tract.
