PURPOSE: The aim of this research was to analyze the place of single cage inserted utilizing oblique-oriented approach in transforaminal lumbar interbody fusion (TLIF) on digital photographs of computed tomography (CT).
METHODS: From January to August 2015, 44 consecutive sufferers with degenerative lumbar illness who underwent TLIF within the L4/5 stage had been retrospectively studied in our division. The only cage was inserted utilizing the oblique-oriented approach; as the primary goal of the research, its place was analyzed utilizing post-operative digital computed tomography photographs.
RESULTS: All cages used within the research had the identical size of 36 mm, which had been inserted into the discs with a 46.04?±?three.09-mm horizontal diameter and 34.25?±?three.59-mm longitudinal diameter. The horizontal and longitudinal diameter of the handled disk established the coordinate. The horizontal and longitudinal coordinate values of the centre of the cage had been zero.08?±?four.12 and 1.20?±?2.76 mm, respectively. The horizontal distance of the cage centre from the midpoint of the disc negatively correlated with that of the entry level from the midpoint of the disc within the coronal aircraft.
CONCLUSION: An extended single cage could be positioned into the L4/5 stage disk by inserting it utilizing the oblique-oriented approach. Its heart can attain the midpoint of the handled disk within the coronal aircraft and the anterior place of the disk within the sagittal aircraft. The entry level of the cage is the additional away from the midpoint of the disk; the cage is the extra apt to succeed in the middle of the disk within the coronal aircraft.
