COMPARISON OF FLUOROSCOPY REDUCING OBLIQUE LUMBAR INTERBODY FUSION L5-S1 (OLIF51) AND STANDARD TRANSFORAMINAL LUMBAR INTERBODY FUSION L5-S1 (TLIF51) METHODS IN THE SURGICAL TREATMENT OF ADULT SPINAL DEFORMITY Floroskopi Kullanımını Azaltan Oblik Lumb

ABSTRACTObjective: The objective of the study was to evaluate the L5-S1 oblique lumbar interbody fusion (OLIF51)and L5-S1 transforaminal lumbar interbody fusion (TLIF51) techniques in relation to several key variables,including the duration of the operation, quantity of blood lost, fluoroscopy time used, radiological outcomeand complications as regards the management of adult spinal deformity.Material and Methods: In this retrospective study, a total of 60 patients who underwent surgical treatmentfor spinal deformities between January 2021 and December 2023 were included in the analysis. Patientswere divided into two groups according to OLIF51 and TLIF51 methods. Demographic data, surgical time,blood loss, hospitalization, fluoroscopy time, and complication rates were recorded. visual analog scale(VAS) and oswestry disability index (ODI) were used for clinical evaluation. Radiological parameters wereanalyzed using disc height and lumbar lordosis angle.Results: The OLIF51 group exhibited a shorter surgical duration (p
