Trauma Case Reports
|April 13, 2018
Summary
A rare fabella fracture, a small bone in the knee, can cause pain and impair function. This case highlights the importance of recognizing this injury, often missed on initial imaging.
Area of Science:
- Orthopedic surgery
- Radiology
- Anatomy
Background:
- The fabella, a sesamoid bone within the gastrocnemius muscle, plays a role in knee joint stabilization.
- Fabella fractures are uncommon and frequently misdiagnosed due to their rarity.
Observation:
- A 38-year-old female sustained a fabella fracture after an electromobile accident.
- Initial diagnosis was confirmed via X-ray plain films.
- Magnetic resonance imaging (MRI) was utilized to further assess the extent of the injury.
Findings:
- The case confirms that fabella fractures can occur due to trauma.
- Radiographic and advanced imaging modalities are crucial for accurate diagnosis.
Implications:
- Increased awareness of fabella fractures is needed in clinical practice.
- Proper diagnostic imaging protocols can prevent missed diagnoses and ensure appropriate patient management.
- Understanding the biomechanics of fabella fractures aids in knee injury assessment.

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

5.6K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
