For Patients and Participants

The FLARE Trial investigates how NHS surgeons can best treat patients who have a cut through both flexor tendons at the base of their finger.

View the FLARE trial animation below to give you an insight into why we are running the trial and what activities we are asking patients to complete.

Repair one or both tendons?

We want to find out whether repairing only the tendon that bends the top of the finger is at least as good for patients as repairing both tendons. If that turns out to be the case, this could potentially save the NHS a lot of time and money. 


Proven treatments

In NHS hospitals up and down the country, surgeons are currently carrying out both types of operations. We know that both types of operations work, and that each one has pros and cons. At the moment, there is not enough research information to weigh up these pros and cons. That’s why we’re doing the trial. 


Looking for 310 volunteers

We are looking for 310 adult patients across the country to take part in the trial. In hospitals that are working with the FLARE trial, patients will be asked to volunteer. If you volunteer, neither you, nor your surgeon decides whether you will have one or two tendons repaired. Instead, this is decided through a scientific process called randomisation. This gives you exactly a 50 percent chance of either type of surgery. 


The care is the same

Other than not knowing which type of surgery you undergo, you will receive the same level of care, compared with the patients who are not taking part in the trial.
