Use of Asymmetric TLIF Technique for the Treatment of Idiopathic Scoliosis

Abstract


Purpose of the study was to determine the possibility of asymmetric transforaminal lumbar interbody fusion (TLIF) application for dorsal spine correction and fixation in patients with idiopathic scoliosis. Dorsal spine correction and fixation using technique of asymmetric transforaminal lumbar interbody fusion on the concave side of lumbar spine deformity was performed in patients, aged 14—58 years, with idiopathic scoliosis. Average preoperative deformity angle made up 78.25° versus 30.25° postoperatively; average correction was 61.6%. For TLIF performance combined implants, i.e. interbody titanium cages filled with autobone, were used. Use of asymmetric TLIF enabled to reduce the slope of lower instrumented vertebra and thus to perform the correction of spine frontal balance. Lordosing effect of cage improved the sagittal profile of the vertebral column while more rapid formation of lumbar corporodesis under conditions of interbody fixation prevented rods and screws fractures in the lower pole of metal constructions.
