Comparative Study Between Posterior Lumbar Interbody Fusion(PLIF) and Intertransverse Process Fusion in Treatment of Spodylolithesis

Comparative Study Between Posterior Lumbar Interbody Fusion(PLF) and Intertransverse Process Fusion in Treatment of Spodylolithesis

The first technique described for interbody fusion was the anterior lumbar interbody fusion (ALIF).(20) For this technique, the intervertebral disc is accessed through a retroperitoneal or transperitoneal approach.

While the posterior approach was first described by Russell Hibbs in 1911, in the 1950's, Cloward (7)popularized the posterior approach for a posterior lumbar interbody fusion (PLIF).

In this study we will try to identify the benefits and outcome of posterior lumbar interbody fusion and inter transverse process bone graft fusion.
