There are at all times a number of project based databases run through the Orthopeadic Research Laboratory. The databases are set up for specific projects of variying duration.
One of the larger project databases running at the moment is the TLIF database which has been accumulating data since 2003 - the analysing of this data is to commence within the next year.
The Anterior/posterior project commenced in 1996. The project is now the focus of a ph.d.- study with a 5-9 year follow up.
