This study aimed to establish a predictive nomogram model for recollapse of fractured vertebra after posterior pedicle screw fixation in thoracolumbar fractures (TLFs). ⋯ A clinical nomogram incorporating 4 variables was constructed to predict fractured vertebra recollapse after posterior pedicle screw fixation for TLFs. The nomogram demonstrated good calibration and discriminative abilities, which may help clinicians to make better treatment decisions.

The aim of the current study was to compare the incidence of postoperative complications among minimally invasive surgery (MIS) tubular, endoscopic, and robot-assisted transforaminal lumbar interbody fusion (TLIF) techniques. ⋯ The current study demonstrated that tubular, endoscopic, and robot-assisted TLIF procedures had similar complication rates. The tubular MIS TLIF reported fewer new neurologic symptoms compared with endoscopic and robot-assisted TLIF procedures at 2 weeks postoperative, with all groups declining in symptom persistency at later time intervals. Average Visual Analog Scale scores continuously improved up to 1 year postoperatively among all groups.

Conventionally, neural transfer of the spinal accessory nerve to the suprascapular nerve for shoulder abduction in traumatic brachial plexus injury is performed via the anterior approach. However, important advantages of the posterior approach have made it an alternative option, such as the proximity of neural coaptation to the muscle to be reinnervated and negating the effects of a second injury to the suprascapular nerve. ⋯ External rotation at the shoulder is better via the posterior approach, but no difference in abduction was noted. Patients who underwent the posterior approach were more satisfied with the recovery, and surgeons preferred the posterior approach.

Short-lasting cough-associated headache (CAH) in patients with Chiari I malformation (CMI) is believed to be due to transient worsening of cerebrospinal flow (CSF) obstruction at the foramen magnum. We assessed changes in CSF flow in response to coughing in CMI patients with CAH and compared with those without CAH and healthy participants (HPs) using real-time magnetic resonance imaging. ⋯ A decrease in CSF flow after coughing in CMI patients with CAH supports the notion that CAH is caused by transient worsening of CSF flow obstruction at the foramen magnum.

Surgical management of lumbar spondylolisthesis requires neural decompression, stabilization, and alignment restoration. Minimally invasive spine approaches offer a wide variety of advantages for spondylolisthesis management. This intraoperative note describes the treatment of L4-L5 lumbar spondylolisthesis with lateral lumbar interbody fusion (LLIF) and percutaneous pedicle screw fixation (PSF). ⋯ LLIF with percutaneous PSF can be an effective technique for treating lumbar L4-L5 spondylolisthesis.
