Chapter 7184extension. The lattice structure interior (500-m interconnected pores with a diamond unit cell structure) provided an optimal region for bony union of the enthesis with the transplanted bone particles (Fig. 3). Six of the ramal components’ condylar heads were treated using a HadSat diamond-like carbon coating; seven remained untreated. Fixation of the ramal component was performed using an average of six titanium Gr 5 screws (Surgi-Tec, Ghent, Belgium; diameter 2.3 mm, length 13 to 17 mm). Fig. 3: Three-dimensional rendering of the ramal component with lattice structure and tunnel for fixation of the enthesis. Red arro subcondylar tunnel and hook-like extension for fixation of the enthesis; blue arro subcondylar groove to guide enthesis' sutures; black arro lattice structure for enthesis' bony ingrowth; orange arro lattice structure for mandibular bony ingrowth into the ramal component.Surgical protocolEach ewe was first sedated using xylazine (0.1 mg/kg) and then shaved over the left mandible. Anesthesia was subsequently given using ketamine (4 mg/kg) and midazolam (0.2 mg/kg) for induction. The sheep was then intubated with a cuffed tube and anesthesia was maintained using mechanical ventilation with an oxygen-isoflurane mixture.
