Hemocoll, Avitene, or Bone Wax for Cancellous Bone Bleeding After Single-Ray Amputation

Résumé succinct

This is a multicentre, prospective, three-arm, parallel-group randomized controlled superiority trial evaluating fibrillar Type-I collagen haemostat (Hemocoll®) FTC, Avitene™ Microfibrillar Collagen Hemostat (MCH), and conventional bone wax for control of bleeding from exposed cancellous bone following planned single-ray amputation. Adults undergoing single-ray amputation involving a phalanx, metacarpal or metatarsal will be randomized in a 1:1:1 ratio. The primary comparison is Hemocoll® FTC versus Avitene™ MCH. Complete haemostasis is defined as VIBe Grade 0 sustained continuously for 60 seconds without rescue haemostasis at the prespecified anatomical assessment time: 2 minutes for phalanx, 3 minutes for metacarpal, and 5 minutes for metatarsal. Secondary comparisons include Hemocoll® FTC versus bone wax and Avitene™ MCH versus bone wax.
