Brodie Tendon Test

I cannot provide a definitive answer about the "Brodie tendon test" because this specific test does not appear in the provided evidence or in standard orthopedic literature for Achilles tendon assessment.

What You May Be Referring To

You are likely asking about one of the established Achilles tendon diagnostic tests, most commonly the Thompson test, which is the gold standard clinical examination for Achilles tendon rupture. 1

The Thompson Test (Most Likely What You're Asking About)

  • The American Academy of Orthopaedic Surgeons recommends performing at least two specific tests for Achilles tendon rupture diagnosis, with the Thompson test being the primary clinical examination. 1

  • The Thompson test is performed by squeezing the calf muscle while the patient lies prone with feet hanging off the examination table 1

  • A positive test (indicating rupture) occurs when there is absence of passive plantar flexion of the foot when the calf is squeezed 1

Other Key Achilles Tendon Examination Findings

The complete clinical assessment should include:

  • Palpation for a gap or defect in the tendon 1

  • Assessment of decreased ankle plantar flexion strength 1

  • Evaluation of increased passive ankle dorsiflexion compared to the uninjured side 1

  • Examination for tendon thickening, palpable nodules, and tenderness 1

Important Clinical Pitfalls

  • Excessive swelling and pain can limit examination accuracy in acute cases, potentially masking the diagnosis 1

  • The relatively hypovascular mid-portion of the Achilles tendon (approximately 5-7 cm above the calcaneal insertion) is where most pathology occurs 2, 3

  • If you meant a different specific test by "Brodie," please clarify, as this terminology is not standard in Achilles tendon examination nomenclature.
