Lesions of the Extensor Tendons at the Hand

Area of Science:

• Orthopedics
• Radiology
• Musculoskeletal Imaging

Background:

• Extensor mechanism disorders of the wrist and hand are prevalent, often more so than flexor system pathologies.
• Untreated or poorly managed conditions can result in significant functional deficits and poor patient outcomes.
• Etiologies include repetitive overuse, trauma, inflammatory conditions, and degenerative tendinopathies.

Purpose of the Study:

• To provide an updated review of extensor tendon disorders affecting the wrist and fingers.
• To focus on the underlying causes and characteristic imaging findings.
• To aid radiologists in achieving accurate and efficient diagnoses.

Main Methods:

• Literature review of extensor tendon pathologies.
• Emphasis on diagnostic modalities like ultrasound and magnetic resonance imaging (MRI).
• Correlation of clinical evaluation with high-resolution imaging findings.

Main Results:

• Extensor tendon pathologies have diverse origins, including overuse, trauma, and inflammatory/degenerative processes.
• Ultrasound and MRI are crucial for evaluating tendon integrity, soft tissues, and dynamic abnormalities.
• Key imaging features are presented to differentiate various extensor tendon disorders.

Conclusions:

• Accurate diagnosis of extensor tendon disorders requires thorough clinical assessment and advanced imaging.
• Understanding specific imaging findings on ultrasound and MRI is essential for effective management.
• This review serves as a guide for radiologists in diagnosing these common wrist and hand conditions.
