OBJECT: Aim of the present study was to proof that for certain complex spinal conditions, MIDLIF technique is very convenient in terms of length of hospitalization, functional recovery and pain relief and time to back to work. METHODS: MIDLF indications were set for patients with not more than 3 unstable levels, presence of osteoporosis (alternative to cemented screws), or cardiomyopathy with anticoagulation with or without spinal stenosis, and or discopathy. Surgical difficulties, operative time, hemoglobin loss and postoperative 45 days, 6 months and one-year follow- up data are shown...

INTRODUCTION: Midline lumbar fusion (MIDLF) using cortical bone trajectory is an alternative method of transpedicular spinal fusion for degenerative disease. The new entry points' location and screwdriving direction allow the approach-related morbidity to be reduced. AIM: To present our preliminary experience with the MIDLF technique on the first 5 patients with lumbar degenerative disease and with follow-up of at least 6 months. MATERIAL AND METHODS: Retrospective analysis was performed on the first 5 patients with foraminal (4) or central (1) stenosis operated on between December 2014 and February 2015...

OBJECTIVE: The objective of this study is to review the clinical outcomes of a novel minimally invasive surgery (MIS) technique for the treatment of instability of the lumbar spine using the cortical bone trajectory (CBT). We present a prospective review of the clinical outcomes from the first 25 consecutive cases in a single unit during the initial learning phase. MATERIALS AND METHODS: The investigation group included the first 25 patients (eight males and 17 females) who underwent MIDLF® since the introduction of this technique in a single unit...

A novel cortical bone trajectory (CBT) screw technique provides an alternative fixation technique for lumbar spine. Trajectory of CBT screw creates a caudo-cephalad path in sagittal plane and a medio-lateral path in axial plane, and engages cortical bone in the pedicle. The theoretical advantage is that it provides enhanced screw grip and interface strength. Midline lumbar fusion (MIDLF) is composed of posterior midline approach, microsurgical laminectomy, and CBT screw fixation. We adopted the MIDLF technique for lumbar spondylolisthesis...

OBJECT: Symptomatic adjacent-segment lumbar disease (ASLD) after lumbar fusion often requires subsequent surgical intervention. The authors report utilizing cortical bone trajectory (CBT) pedicle screw fixation with intraoperative CT (O-arm) image-guided navigation to stabilize spinal levels in patients with symptomatic ASLD. This unique technique results in the placement of 2 screws in the same pedicle (1 traditional pedicle trajectory and 1 CBT) and obviates the need to remove preexisting instrumentation...
