Open Wedge High Tibia Osteotomy

November 19, 2007 updated by: AO Clinical Investigation and Publishing Documentation

Comparison of Open Wedge High Tibia Osteotomy Surgeries Using Colloss E and Tomofix and Tomofix Only, Regarding the Bone Healing

The aim of this RCT is to show, that in a patient group receiving COLLOSS E combined with TomoFix for medical open wedge high tibial osteotomy, the onset of bone healing is earlier in time, compared to patients receiving TomoFix without COLLOSS E.
