Injuries to the carpal bones revisited

Area of Science:

• Radiology
• Orthopedics
• Anatomy

Background:

• Falls on the outstretched hand are a common cause of emergency room visits.
• Carpal region pain after such falls presents diagnostic challenges due to complex anatomy and patient discomfort.
• Standard radiological examinations may appear normal despite persistent pain, necessitating further investigation.

Purpose of the Study:

• To review the spectrum of carpal injuries resulting from falls on the outstretched hand.
• To correlate typical imaging appearances with injury mechanisms.
• To emphasize the importance of radiologist familiarity with carpal anatomy and injury patterns.

Main Methods:

• Review of various imaging techniques used for carpal injuries.
• Illustration of common and uncommon carpal injuries.
• Explanation of injury mechanisms and characteristic radiological findings.

Main Results:

• Complex carpal anatomy can impede initial imaging interpretation.
• Patient discomfort can limit the acquisition of adequate radiographic views.
• A spectrum of carpal injuries, both common and rare, can be identified with appropriate imaging.

Conclusions:

• Accurate diagnosis of carpal injuries requires a thorough understanding of anatomy and injury mechanisms.
• Advanced or varied imaging techniques may be necessary when initial radiographs are inconclusive.
• Radiologists must be proficient in identifying diverse carpal pathologies to ensure appropriate patient management.
