MANTIS has been given the greenlight and is now open to recruitment.

 At present, there is little evidence for an effective drug in the treatment of Avascular Necrosis (AVN) of the femoral head. This is an uncommon yet devastating condition, primarily effecting a younger patient population. The MANTIS trial is a blinded, randomised, placebo controlled trial looking at the use of bisphosphonates and whether they can help to delay or prevent the progression of AVN.

 If you would like to be involved as a recruiting site, please contact or follow the trial on twitter for the latest news @mantis_trial
