Search Strategy[edit | edit source]
I searched information about the Thompson test on google-books, where I found a lot information in scientific books. On Pubmed I found some articles about it.
Definition/Description[edit | edit source]
The Thompson test examines the integrity of the Achilles tendon and is performed as a clinical test to identify the presence of a complete tear of the tendon.
Clinically Relevant Anatomy[edit | edit source]
To make it more clearly, Simmonds and Thompson separated the M.Gastrocnemius tendon from the M. Soleus down to 10 cm above the Achilles tendon, because that is the place where the fibres form the tendon. By squeezing the calf, the M. Soleus deformed which made the overlying M. Gastrocnemius tendon to bow away from the Tibia which resulted in the plantar flexion. The M. Soleus did not move longitudinal, but the M. Gastrocnemius muscle moved about 1 cm proximally, as showed our ultrasound findings. This proves that the M. Soleus has to be 100% ruptured to get no plantar flexion.
The result of the Simmonds-Thompson test mainly gives an idea about the integrity of the M. Gastrocnemieus. Plantar flexion is caused by posterior flexing of the calf muscles and lesser by proximal movement of the bellies of the M. Gastrocnemius.
Purpose
To assess for achilles tendon rupture
Technique
[edit | edit source]
The patient lies prone with their legs straight and their heels placed just over the edge of the table. The examiner then squeezes the gastrocnemius-solues complex. When the achilles tendon is intact, the patient should plantar flex the foot upon squeezing the gastroc-soleus complex. If the patient does not plantar flex the foot upon squeezing, the test is positive for achilles tendon rupture.[1]
