The lumbar [[TLIF cage]] “Synchro“ is made of an anterior and a posterior element. Both are linked with a [[joint]]. The mobility of both elements secures an optimized implant insertion. The anterior element is inserted into the [[disc space]] through the [[lumbar foramen]] and is properly oriented with the help of the posterior element. In its optimized positioning, the angle between both elements can vary from 45 to 90 degrees.

===== Case series =====

Under [[computed tomography]] (CT) guided spinal navigation the [[TLIF]] procedure was performed. Clinical outcome scores [[visual analog scale]] (VAS), [[Oswestry disability index]] (ODI) and short form-36 health survey questionnaire (SF-36) were obtained preoperatively, 6 and 12 months after surgery. Radiological data were acquired preoperatively, after 6 weeks, as well as 6 and 12 postoperatively and included measurements for [[disc height]] (anterior/posterior), [[foraminal height]], segmental and global [[lumbar lordosis]].

71% of the included patients have undergone previous lumbar surgery. In total, 80 [[SYNCHRO]]® cages have been implanted. The clinical results revealed a highly significant improvement of VAS, ODI and SF-36 after 6 and 12 months, compared to baseline levels (p < 0.05). Radiological analysis revealed a significant increase in anterior and posterior disc height, foraminal height, segmental and global lumbar lordosis postoperatively (p < 0.05). 47 out 49 patients (96%) showed evidence for fusion at the 12 months follow-up. Cage dislocation was found in 1 of 80 implanted cages (1%), which required revision surgery. Two dural tears occurred intraoperatively, which have been fixed. Another two patients needed surgical revision due to infection. The overall complication rate was 10% (n = 5/49).

The current study delineates satisfactory clinical and radiological results by using a novel articulating TLIF-cage. The implant-related complication rate was acceptable with low revision rate
