Study information
Scientific title
Efficacy and safety aspects of biodegradable fixation systems: a randomised clinical trial
Acronym
FixITT
Study hypothesis
The performance of the Inion biodegradable osteofixation system is inferior compared to a titanium system regarding the treatment of zygoma, Le Fort I fractures, Le Fort I osteotomies, mandibula fractures and Bi-lateral Sagittal Split Osteotomies (BSSO) of the maxillofacial skeleton by healthy patients with regard to bone healing, stability and complications like, infections, plate dehiscence, hypersensitivity and palpability.
Ethics approval

Primary outcome measure
Bone healing is the primary outcome measure. The definition of bone healing is: healing of the bone segments after eight weeks without clinical and radiological signs of disturbed bone healing.
Bone healing related complications are not allowed during this period.
Secondary outcome measures
1. Inflammatory reaction present (redness, swelling, sensitivity, warmth, function impairment, fistula or pus drainage), assessment visual and manually
2. Seriousness inflammatory reaction (mild, serious), assessment visual and manually
3. Palpability, assessment manually
4. Dehiscence, assessment visual
5. Occlusion, assessment visual
6. Bone formation (screw holes, fracture crevice)
7. Pain, evaluated by a Visual Analogue Scale (VAS)
8. Cold/warm sensitivity
9. Mandibular function, evaluated by a Mandibular Function Impairment Questionnaire (MFIQ)
10. Direct costs within the health care
11. Direct costs outside the health care
12. Indirect costs outside the health care
13. Antibiotic use
14. Analgesic use
15. Re-operation required
16. Reasons re-operations (plate/screw exposition, plat/screw fracture, loosening of plates and screws, inadequate bone healing, inadequate reduction, infection or other reasons)
Overall trial start date
