Titanium Mesh Cage

Specifications - Titanium Mesh Cage

The introduction of the Titanium Mesh Cage in spinal surgery has opened up a variety of applications that are realizable as a result of the versatility of the implant.

Since their debut in 1986, Titanium Mesh Cages have been extensively employed for spine restoration. It is not necessary to harvest huge structural bone grafts because these cages can be employed as structural devices containing autologous local bone or iliac crest bone transplant.

Sizes and Uses of Titanium Mesh Cage

Titanium Mesh Cage are available in various diameters and lengths.
Diameters: 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm and 26mm
Lengths: 60mm, 70mm, 80mm, 90mm and 100mm

In spinal fusion surgery, the worn-out or injured disc that lies between two vertebrae is removed, and the empty disc space is filled with a bone transplant. The titanium mesh cage, acting as a support structure or spacer, is subsequently put into the disc space. It maintains the disc space, encourages fusion of the neighbouring vertebrae, and aids in restoring the spine’s natural height and alignment.

Typically porous or perforated, the titanium mesh cage allows bone transplant material to be put inside. As a result, the fusion process is facilitated by encouraging bone growth through and around the cage. As new bone tissue grows around the cage, the cage eventually fuses with the surrounding bone, giving the fused spinal segment support and stability.

The principal advantage of the Titanium Mesh Cage is a reduction in donor site morbidity. Because it can provide immediate load-bearing support to the anterior column, a structural bone graft is not necessary. Instead, a less invasive autograft harvest can be done to acquire cancellous bone to fill the cage and pack the disc space around the cage. For a single-level anterior cervical discectomy and fusion, a small cortical window can be made on top of the anterior iliac crest through which cancellous autograft can be obtained without disrupting the tables of the ilium. In most individuals, a 1-inch incision is sufficient to harvest this type of graft. The iliac crest donor site then can be reconstituted by packing the defect with cancellous allograft or demineralized bone matrix. With this approach, donor site pain and complications have been minimal in the authors’ experience. For reconstructions after corpectomy, cages can be filled with the resected vertebral body bone that is generated locally. Additional cancellous autograft can be harvested, if necessary, via the cortical window technique described above. Alternatively, bone graft extenders such as demineralized bone matrix can be used.
