What is a Boyes Test?

The “Boyes Test” you are referring to is a specific medical test used to evaluate the integrity of the central slip in patients with extensor tendon injuries to the hand. The proximal interphalangeal joint (PIP joint) is extended by the central slip, a component of the finger’s extensor mechanism. Injuries to the central slip can lead to a condition known as “mallet finger.”

Purpose

In patients with hand extensor tendon injuries, assess the integrity of the central slip.
To examine the distal interphalangeal joint, utilize the boyes test.

The purpose of the Boyes Test is to assess whether the central slip is intact or disrupted. It is typically performed by a healthcare professional, such as an orthopedic surgeon, Physical therapist or hand therapist. The test involves passive manipulation of the finger joint to determine the presence or absence of active extension at the PIP joint.

How to Perform Boyes Test?

For the test, the patient is sitting down.
During the Boyes Test, the examiner will gently hold the patient’s PIP joint in extension while allowing the distal interphalangeal joint (DIP joint) to flex naturally.

  • The patient is requested to flex the DIP Joint while the PIP Joint is passively extended.
  • The patient should be able to flex the DIP Joint if the extensor mechanism is healthy.
  • The patient won’t be able to flex the DIP Joint if they have a central slip injury.

Video of the Test

It is important to note that the Boyes Test is just one part of a comprehensive evaluation of extensor tendon injuries in the hand. Other clinical tests and imaging studies may also be used to assess the extent and nature of the injury. Treatment options will depend on the specific findings and may include splinting, hand therapy, or, in severe cases, surgical intervention to repair the injured tendon. If you suspect you have an extensor tendon injury or are experiencing hand-related issues, it is essential to consult with a healthcare professional for proper evaluation and management.
