The effect of diamond like carbon (DLC) and hydroxyapatite (HA) coatings on soft tissue reactions to external fixation screws under load was investigated. Soft tissue reactions to implants with uncoated stainless steel, fully HA coated and DLC coated pins were observed on 40 mature ewes. Transmission electron microscopy (TEM) and scanning electron microscopy were used to study the biofilm formation and microbiology analysis. No direct contact of any implant with epithelium was observed. In all cased a layer o protein deposited on the surface of the pin with cellular debris attached. The surface of DLC coated pins had a significantly lower number of bacterial colonies compared to the stainless steel and fully coated HA.
