Bone ingroth in cages assessed on CT with bony bridging score
Achtergrond van het onderzoek
A posterior lumbar Interbody fusion (PLIF) is an effective surgical technique to reduce symptoms and improve function in patients with spondylolisthesis. The PLIF technique is performed with bilateral interbody cages, like the titanium cages of EIT®. These cages are 3D printed and simulate the bone structure and bone geometry. The surface for bone Ingrowth is large and could result in bone ingrowth and fusion. It is expected that due to the bone growth into the cage a solid stable bony fusion can be achieved. If it appears that inter corporal fusion with EIT® cages is possible, the use of posterolateral allografts in the PLIF technique will be unnecessary and the risk of subsidence of the cages will be reduced. In literature little is known about valid and reliable measuring and evaluating bone growth. The 'bony-bridging-score' is developed to evaluate the anterior lumbar interbody fusion (ALIF) procedure with PEEK cages. However, it is unknown whether this outcome measure is also useful for the PLIF procedure with 3D printed Titanium EIT cages. A single center prospective case series including 15 patients is planned to evaluate the primary objective. The objective is to determine the feasibility and usability of the bony bridging score and to investigate the degree of radiological bone ingrowth in patients who are eligible for a lumbar spinal fusion with PLIF (EIT®) cages.
