Study Design: Retrospective cohort study. Background: Percutaneous pedicle screws (PPS) have the advantage of being able to better preserve the paraspinal muscles when compared with a traditional open approach. However, the nature of changes in postoperative paraspinal muscle after damage by lumbar fusion surgery has remained largely unknown. It is clinically important to clarify and compare changes in paraspinal muscles after the various surgeries. Objective: (1) To determine postoperative changes of muscle density and cross-sectional area using computed tomography (CT), and (2) to compare paraspinal muscle changes after posterior lumbar interbody fusion (PLIF) with traditional open approaches and minimally invasive lateral lumbar interbody fusions (LLIF) with PPS. Methods: We included data from 39 consecutive female patients who underwent open PLIF and 23 consecutive patients who underwent single-staged treatment with LLIF followed by posterior PPS fixation at a single level (L4-5). All patients underwent preoperative, 6 months postoperative, and 1-year postoperative CT imaging. Measurements of the cross-sectional area (CSA) and muscle densities of paraspinal muscles were obtained using regions of interest defined by manual tracing. Results: We did not find any decrease of CSA in any paraspinal muscles. We did find a decrease of muscle density in the multifidus at 1 year after surgery in patients in the PILF group, but not in those in LLIF/PPS group. Conclusions: One year after surgery, a significant postoperative decrease of muscle density of the multifidi was observed only in patients who underwent open PLIF, but not in those who underwent LLIF/PPS.

Minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) is a well-accepted procedure with good outcomes. Robotics has the potential to augment these outcomes. This video demonstrates and discusses how surgeons can implement the use of a robotic device in an MIS TLIF workflow. The planning software and robotic arm guidance allow the surgeon to use intraoperative CT to guide the placement of pedicle screws in an MIS TLIF with optimal trajectory and decreased radiation. As robotic technology continues to improve, developing safe workflows that integrate robotics with currently well-established techniques should improve patient outcomes.The video can be found here: https://youtu.be/rJWOa6XVLW0.

The functional cross-sectional area (FCSA) represents the lean muscle mass; furthermore, FCSA is a useful marker of the contractile ability of a muscle following a spine surgery. However, the benefits of unilateral fixation and MI-TLIF on paraspinal muscles have not been defined.</p></sec><sec><title>Methods</title><p>We performed a retrospective imagenological review on eleven patients who underwent unilateral MI-TLIF and unilateral transpedicular screw lumbar placement. FCSAs of the multifidus and erector spinae were measured 1 year after surgery at adjacent levels and were compared to the contralateral intact muscles. Measurement differences between the surgical and nonsurgical sites were compared. The interobserver reliability was calculated using an intraclass correlation coefficient.</p></sec><sec><title>Results</title><p>The mean FCSA at the surgical site was 20.97±5.07 cm<sup>2</sup> at the superior level and 8.89±2.87 cm<sup>2</sup> at the inferior level. The mean FCSA at the contralateral nonsurgical site was 20.15±5.95 cm<sup>2</sup> at the superior level and 9.20±2.66 cm<sup>2</sup> at the inferior level was. The superior and inferior FCSA measurements showed no significant difference between the surgical and nonsurgical sites (<italic>p</italic>=0.5, <italic>p</italic>=0.922, respectively).</p></sec><sec><title>Conclusions</title><p>Using a mini-open tubular approach through the sulcus between the longissimus and iliocostalis, MI-TLIF and unilateral pedicle screw instrumentation produced minimal paraspinal muscle damage at the superior and inferior adjacent levels.</p></sec>
