interbody cage

interbody cage

(ĭn′tĕr-bŏd″ĕ)
A hollow, tube-shaped device placed between adjacent vertebral bodies in spinal fusion surgeries to improve or enhance bony fusion (“arthrodesis”). The cage is filled with either a bone graft or with bone graft substitutes.

directly compared the bony ingrowth potential and biomechanical properties of a novel 3DP porous titanium alloy (PTA) interbody cage with commercially available polyetheretherketone (PEEK) and plasma sprayed porous titanium coated PEEK (PSP) interbody cages in an ovine lumbar interbody fusion model [31].

The rhBMP-2 was completely placed in the interbody cage. Autografts with demineralized bone matrix (DBM) were used for posterolateral fusion in both groups.
Interbody cage of appropriate size was then placed after filling it with graft.
MI-TLIF is a procedure which has a steep learning curve and placing screws and their extenders are not advised on the same side due to difficulty in accessing the operating field and increased intraoperative time, thus we inserted the pedicle screws on the contralateral side, and on the ipsilateral side and the pedicle was cannulated only by needle sleeves; ipsilateral screws were only inserted after placement of the interbody cage.
VEO's interbody cage is made from Zeniva[R] PEEK rod stock that TranS1 offers in various sizes, including widths of 17-mm and 22mm and lengths from 40-mm to 60-mm.
The implant screwing results in increase of intervertebral space and, consequently, appearance of opening effect with wedge of interbody cage.

The aim of the trial is to evaluate the safety and efficacy of the addition of ALLOB to the standard care of procedure, involving an interbody cage with bioceramic granules being implanted in order to achieve fusion of the lumbar vertebrae.
Compared with posterior surgeries, a larger interbody cage can be implanted, thus achieving more indirect decompression of spinal canal through further increase of foramina and canal area, as well as disc height.
