POSTERIOR LUMBAR INTERBODY FUSION USING LUMBAR ALLIGATOR SPINAL SYSTEM. - VIDEO PRESENTATION
Journal Title: Journal of Turkish Spinal Surgery - Year 2003, Vol 14, Issue 1
Abstract
Although posterior lumbar interbody fusion (PLIF) using cages is a useful procedure, there are problems in terms of bony fusion in case with cage alone technique. The Lumbar Alligator Spinal System has been developed to serve as an auxiliary immobilization material for this procedure. The Lumbar Alligator Spinal System is composed of two plates positioned on both sides of the spinous process, and a transverse system that connects these plates. The two plates are connected by combining on the cephalic side. The insides of the plates contain two rows of spikes that bite into the cortical bone and clamp the spinous process. Irregularities on the outsides of the plates are formed to enable the transverse system to engage with the plates and securely hold them in position. When transverse system is composed of two hooks and transverse pin, which engage with the left and right plates, and a nut. There are two types of hooks consisting of a hook incorporated in the transverse pin and a hook into which the nut is inserted. The pin is inserted into the hook and passed through the hook on the opposite side. The transverse system is then completed by tightening this pin with the nut.
