BACKGROUND: Cortical bone trajectory (CBT) screws are popular for spinal fixation, but their ideal diameter has not been determined. Studies using postoperative computed tomography (CT) have revealed ample bone marrow…

Background: Here, we present our experience with the minimally invasive (MI) transpsoas approach for lumbar corpectomy and stabilization. Transpsoas approach accesses the lumbar spine and includes both the direct lateral…

Contexte: Les chirurgies lombaires instrumentées, telles que l’arthrodèse ou la prothèse discale lombaires, sont de plus en plus utilisées aux États-Unis pour le traitement de la lombalgie, leurs taux d’utilisation…

Pedicle screw fixation and fusion are the gold standard for the treatment of spinal instability. Screw failures such as pullout and breakages have been reported during the past several years…

OBJECTIVE: To evaluate the mechanical response of a narrow surface cage that we designed for full endoscopic oblique lateral lumbar interbody fusion (FE-OL-LIF).METHODS: A finite element (FE) model of lumbar…

OBJECTIVE: Minimally invasive surgery (MIS), or percutaneous, lumbar pedicle screw placement is commonly done, but the percutaneous nature of this makes posterior arthrodesis extremely difficult. Many times, surgeons will simply…

PURPOSE: Although many risk factors for cage retropulsion (CR) following lumbar interbody fusion (LIF) have been described in the literature, they still remain controversial. The purpose of this study is…

BACKGROUND: Transforaminal lumbar interbody fusion (TLIF) is presently the most used method to achieve lumbar interbody fusion worldwide. The special preparation and cage insertion imply a risk of an undesirable…
