Scientific title
A randomised prospective trial comparing bioabsorbable versus titanium plates in the treatment of mandibular and zygomatic fractures
Acronym
Study hypothesis
Mandibular and zygomatic fractures are conventually fixed by open reduction and internal fixation using titanium plates and screws. Between 18-35% of these plates are subsequently removed due to complications such as loosening.
Bioabsorbable plates are now available as an alternative to metal plates. The potential advantage of using resorbable plates is that the reoperation rate to remove titanium plates that develop complications would be greatly reduced.
The Inion(R) bioabsorbable material comprises the polymers L-polylactic acid, D/L-polylactic acid, trimethylene carbonate and polyglycolic acid. The material degrades by hydrolysis into carbon dioxide and water, in a similar fashion to "dissolving" sutures. The degradation profile provides initial stability to the facial bone and then progressive.
Although bioabsorbable plates have been used in facial fractures there is no prospective data to confirm that they are equivalent to titanium plates. A prospective comparison of the two systems would define whether bioabsorbable plates have a lower complication rate and whether a reduction in reoperation rate can be achieved.
The Null hypothesis to be answered is: there is no difference in the re-operation rate in mandibular and zygomatic fracture repair between titanium and Inion(R) bioabsorbable plates.

Intervention
All patients presenting to the maxillofacial trauma service at University Hospital Birmingham with mandibular and maxillary fractures will be randomised to two treatment arms:
1. Conventional treatment with ORIF using titanium miniplates
2. ORIF using bioabsorbable plates
Invasive procedures and investigations: no change in pre-operative workup will be required
Duration of study: outpatient review at 1 week, 6 weeks, six months and 12 months
End points/outcomes: a comparison of complication rates in each group.
Expected complications: infection, loosening of plates and screws, plate fracture, plate exposure (in mouth), malunion, non-union of fracture
