The optimal treatment for neurologically intact thoracolumbar fractures remains controversial. Percutaneous pedicle screw fixation (PPSF) has been proposed for these fractures; however, achieving satisfactory reduction can be challenging. This study applied robot-assisted PPSF to enhance treatment outcomes.
The optimal treatment for neurologically intact thoracolumbar fractures remains controversial. Percutaneous pedicle screw fixation (PPSF) has been proposed for these fractures; however, achieving satisfactory reduction can be challenging. This study applied robot-assisted PPSF to enhance treatment outcomes. The investigators retrospectively analyzed the medical records of 182 consecutive patients with thoracolumbar burst fractures treated with PPSF, with (n=88) and without (n=94) robotic assistance, at our hospital between April 2017 and June 2019. The participants were evaluated surgical time, intraoperative bleeding, radiation dosage, accuracy of screw placement, fractured vertebral height, Cobb's angle, surgery efficacy (pain relief and limb function), and implant failure to assess the potential advantages of robot-assisted PPSF. Robot-assisted PPSF for thoracolumbar burst fractures reduces surgery time and intraoperative bleeding, enhances screw placement accuracy, and achieves better reduction compared to the free-hand technique. This approach effectively prevents endplate collapse and recurrence of kyphosis post-surgery. However, functional recovery in the short term is similar between the two methods.
