Lumbar Interbody Fusion

The Medtronic Infuse Bone Graft/LT-Cage Lumbar Tapered Fusion Device is commonly used as a stabilizer and source of fusion material for interbody fusions.  Usually two of these devices are placed side by side in the operative interspace.

In this blog I will introduce the topic of lumbar interbody fusions (LIF procedures) as a group of related procedures and discuss the many things they share in common. Starting with tomorrow’s blog we will examine the procedures individually and point out their distinguishing characteristics. As I have said in previous blogs most interbody fusions can be done through relatively small incisions, with very little blood loss and with very rapid convalescence. In each case the entire intervertebral disc is removed and replaced by a cage, either titanium or polyether ether ketone (PEEK), filled with a matrix with adsorbed BMP. All of the procedures include a form of spinal fixation to hold the bones in register until fusion takes place, titanium plate & screws for anterior fusions and titanium screws & rods for posterior and lateral fusions. At Schlesinger Pain Centers I feel that it is my job to know when a patient should be referred to a surgeon for possible lumbar fusion, but the details of which approach is better for a particular patient is really the province of the surgeon.
