The Thompson Test for Ruptured Achilles Tendon.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Musculoskeletal Imaging

Background:

• Achilles tendon ruptures are common injuries, particularly in athletes.
• A key diagnostic challenge is that active plantar flexion can still be present despite a complete rupture.
• Misdiagnosis can lead to delayed treatment and poorer outcomes.

Purpose of the Study:

• To highlight a simple diagnostic maneuver for Achilles tendon ruptures.
• To emphasize that active plantar flexion does not exclude this injury.
• To improve the prompt and accurate diagnosis of Achilles tendon injuries.

Main Methods:

• Review of clinical diagnostic techniques for Achilles tendon rupture.
• Focus on a specific, easily performed physical examination test.
• Discussion of the clinical significance of active plantar flexion in diagnosis.

Main Results:

• Active plantar flexion of the foot is not a reliable indicator to rule out an Achilles tendon rupture.
• A specific clinical test can aid in the prompt diagnosis of this injury.
• Early and accurate diagnosis is crucial for optimal patient management.

Conclusions:

• Clinicians should not rely solely on the presence of active plantar flexion to exclude Achilles tendon rupture.
• A straightforward diagnostic approach can facilitate timely identification of the injury.
• Prompt diagnosis improves treatment strategies and patient prognosis for Achilles tendon injuries.
