Lumbar fusion was performed using transforaminal interbody fusion (TLIF) devices and posterolateral fusion. To eliminate confounding parameters, in all patients interbody fusion was indicated by lumbar degenerative pathologies, and surgery was performed using the same fusion device. Treatment efficacy was evaluated using scores describing pain (visual analogue scale [VAS]) and health impairment (EQ\u20105D, Oswestry Disability Index [ODI]). The influence of patient age, obesity, active smoking status, and co\u2010morbidities on clinical outcome and perioperative complications was analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The patient population reviewed had improved VAS (<jats:italic>P<\/jats:italic><jats:sub>(leg pain)<\/jats:sub> \u2264 0.0001, <jats:italic>P<\/jats:italic><jats:sub>(back pain)<\/jats:sub> \u2264 0.0001), ODI (<jats:italic>P<\/jats:italic> \u2264 0.0001), EQ\u2010VAS (<jats:italic>P<\/jats:italic> \u2264 0.0001), and EQ\u20105D subscales \u201cmobility\u201d, \u201cself\u2010care\u201d, \u201cpain\u201d, and \u201canxiety\u201d (<jats:italic>P<\/jats:italic><jats:sub>(mobility)<\/jats:sub> \u2264 0.0001, <jats:italic>P<\/jats:italic><jats:sub>(self\u2010care)<\/jats:sub>\u2009=\u20090.41, <jats:italic>P<\/jats:italic><jats:sub>(pain)<\/jats:sub> \u2264 0.0001, <jats:italic>P<\/jats:italic><jats:sub>(anxiety)<\/jats:sub>\u2009=\u20090.011) postoperatively. Neither advanced patient age, nor increased body mass index (BMI), hypertension, or active smoking status had a significantly limiting influence on the success of minimally invasive spinal surgeries (MIS). Duration of surgery strongly correlated with the number of spinal levels treated and with intraoperative blood loss (<jats:italic>r<\/jats:italic>\u2009=\u20090.774, <jats:italic>P<\/jats:italic> \u2264 0.0001, <jats:italic>n<\/jats:italic>\u2009=\u2009208).

When compared to non\u2010smokers, smokers were younger (<jats:italic>P<\/jats:italic> \u2264 0.0001), and had a significantly lower BMI (<jats:italic>P<\/jats:italic>\u2009=\u20090.001), shorter durations of surgery (<jats:italic>P<\/jats:italic> \u2264 0.0001), decreased intraoperative blood loss (<jats:italic>P<\/jats:italic>\u2009=\u20090.022), and shorter hospital stays (<jats:italic>P<\/jats:italic>\u2009=\u20090.006), respectively.
