Imaging of patellar fractures

Area of Science:

• Orthopedic Surgery
• Radiology
• Trauma Care

Background:

• Patellar fractures represent approximately 1% of all skeletal fractures.
• Patellar integrity is crucial for knee extension and preventing extensor mechanism injury.
• Accurate fracture classification is essential for effective patient management.

Purpose of the Study:

• To review normal patellar anatomy.
• To describe mechanisms of patellar fracture.
• To classify different types of patellar fractures and introduce therapeutic management.

Main Methods:

• This is a pictorial essay.
• Review of normal patellar anatomy.
• Classification of patellar fractures based on morphology and displacement.

Main Results:

• Direct trauma typically causes stellate patellar fractures.
• Indirect trauma commonly results in transverse patellar fractures.
• Fracture displacement suggests potential retinacular injury.

Conclusions:

• Patellar fractures require precise classification for optimal treatment.
• Understanding injury mechanisms aids in diagnosis and management.
• Radiographic assessment is vital for identifying fracture type and associated injuries.
