Thompson test

The Thompson test, also known as the Simmonds-Thompson test, is a clinical examination used to diagnose a complete rupture of the Achilles tendon. This test is named after the British orthopedic surgeon, Frank Simmonds, and the American orthopedic surgeon, David Thompson.

Procedure

The Thompson test is performed with the patient lying prone on an examination table, with their feet hanging off the edge. The examiner squeezes the calf muscle of the affected leg. In a normal response, this action causes the foot to plantarflex (point downward). If the Achilles tendon is ruptured, the foot will not move, indicating a positive Thompson test.

Clinical Significance

A positive Thompson test is a strong indicator of an Achilles tendon rupture. This condition often occurs in athletes and can result from sudden, forceful movements such as jumping or sprinting. Early diagnosis and treatment are crucial for optimal recovery and to prevent long-term complications.

Related Examinations

Other clinical tests used to diagnose Achilles tendon injuries include the Matles test and the O'Brien needle test. Imaging studies such as ultrasound and magnetic resonance imaging (MRI) can also be used to confirm the diagnosis.

Treatment

Treatment options for an Achilles tendon rupture may include both non-surgical and surgical approaches. Non-surgical treatment typically involves immobilization of the foot and ankle in a cast or brace, while surgical treatment involves repairing the torn tendon. Rehabilitation exercises are essential in both approaches to restore strength and flexibility.
