STUDY DESIGN: Retrospective cohort research.
PURPOSE: To check the medical and radiological outcomes of modified mini-open transforaminal lumbar interbody fusion (modMOTLIF) and open TLIF (OTLIF).
OVERVIEW OF LITERATURE: Minimally invasive transforaminal lumbar interbody fusion (MTLIF) is related to much less blood loss, shorter hospital keep, and fewer ache. Nevertheless, it has considerations like elevated radiation publicity, steep studying curve, and instrumentation price. We modified the MTLIF method by direct freehand insertion of pedicle screws utilizing stab incisions with out tubular retractors.
METHODS: The research included 24 sufferers within the modMOTLIF group and 27 sufferers within the OTLIF group. The common follow-up interval was 25.6 months. Medical outcomes had been measured utilizing Visible Analog Scale (VAS) and Oswestry Incapacity Index (ODI) scores. Serial X-rays had been acquired at 1, three, 6, 12, and 24 months to evaluate the union and presence of instability. We additionally in contrast blood loss and size of hospital keep in each teams.
RESULTS: All sufferers confirmed progressive enchancment in VAS and ODI scores. No variations had been noticed within the preoperative and postoperative ODI and VAS leg scores between the teams. The rapid postoperative VAS again rating was considerably larger within the OTLIF group than within the modMOTLIF group; nonetheless, no distinction was noticed at 1 and a couple of years. Radiological evaluation confirmed nonunion in a single and two sufferers within the OTLIF and modMOTLIF teams, respectively. The common blood loss was 63 mL within the mod-MOTLIF group and 254 mL within the OTLIF group. The imply hospital keep was three days for the modMOTLIF group and 5 days for the OTLIF group.
CONCLUSIONS: modMOTLIF was related to lowered blood loss and shorter hospital keep in contrast with OTLIF. No vital variations had been noticed within the medical and radiological outcomes between the teams after 2 years regardless of lowered again ache within the rapid postoperative interval in sufferers who underwent modMOTLIF.
