[Scaphoid fractures: diagnosis and therapy].

Area of Science:

• Orthopedic Surgery
• Radiology
• Sports Medicine

Background:

• Scaphoid fractures require prompt diagnosis for optimal outcomes.
• Standard radiography misses a significant percentage of scaphoid fractures.
• Clinical suspicion necessitates further investigation beyond initial X-rays.

Purpose of the Study:

• To review diagnostic and management strategies for scaphoid fractures.
• To highlight the limitations of conventional imaging in scaphoid fracture detection.
• To discuss the role of advanced imaging and treatment modalities.

Main Methods:

• Review of clinical examination and history taking.
• Evaluation of diagnostic accuracy of radiography, bone scintigraphy, MRI, and CT.
• Analysis of treatment outcomes for stable and unstable scaphoid fractures.

Main Results:

• Initial X-rays fail to detect over 20% of scaphoid fractures.
• The optimal supplemental diagnostic tool (bone scintigraphy, MRI, CT) is not definitively established.
• Below-the-elbow casting is suitable for stable fractures; unstable and proximal pole fractures require surgical intervention.

Conclusions:

• Early and accurate diagnosis is paramount for scaphoid fracture management.
• Advanced imaging techniques are essential when initial radiography is negative despite clinical suspicion.
• Treatment decisions should integrate fracture stability, location, and patient-specific factors.
