Summary
Vacuum phenomenon (VP) in closed pelvic fractures is rare but detectable by CT. Patients with VP showed increased fracture progression, highlighting the need for orthopedic awareness in fragility fractures.
Area of Science:
- Orthopedics
- Radiology
- Trauma Surgery
Background:
- Vacuum phenomenon (VP) is a rare occurrence in closed pelvic fractures.
- Understanding its prevalence and clinical implications is crucial for patient management.
Purpose of the Study:
- To determine the prevalence of VP in closed pelvic fractures.
- To analyze the clinical findings associated with VP in these fractures.
- To compare clinical outcomes between pelvic fractures with and without VP.
Main Methods:
- Retrospective review of 197 patients with closed pelvic fractures (2012-2018).
- Diagnosis of pelvic fractures using plain radiography and computed tomography (CT).
- Evaluation of VP prevalence, clinical findings, and radiological characteristics.
Main Results:
- VP was detected in 3.6% of patients (9/197) via CT.
- VP was significantly associated with a higher rate of fracture progression (42.9% vs. 11.3%).
- Patients with VP showed trends towards more fragility fractures of the pelvis (FFP) and less bone union.
Conclusions:
- CT is valuable for detecting VP in pelvic fractures.
- Clinicians should consider VP, particularly in cases of FFP progression.

01:26Muscles of the Pelvic Floor and Perineum
3.8K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.

01:26Pneumothorax-I
1.0K
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

01:18Assessment of the Abdomen II: Percussion
1.5K
Percussion is a fundamental technique used to assess the liver, spleen, and abdominal organs by tapping the abdomen and interpreting the resulting sounds. This method helps identify fluid, distention, and masses through variations in sound, such as the high-pitched tympany of air-filled areas and the dullness of solid masses. Understanding how to percuss these organs provides valuable information for healthcare professionals in diagnosing conditions early.

Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...
