Multicenter Study Clinical Trial
Can triggered electromyography monitoring throughout retraction predict postoperative symptomatic neuropraxia after XLIF? Results from a prospective multicenter trial.
This multicenter study aims to evaluate the utility of triggered electromyography (t-EMG) recorded throughout psoas retraction during lateral transpsoas interbody fusion to predict postoperative changes in motor function. ⋯ Prolonged retraction time and coincident increases in t-EMG thresholds are predictors of declining nerve integrity. Increasing t-EMG thresholds, while predictive of injury, were also observed in a large number of patients without iatrogenic injury, with a greater predictive value in cases with extended duration. In addition to a careful approach with minimal muscle retraction and consistent lumbar plexus directional retraction, the incidence of postoperative motor neuropraxia may be reduced by limiting retraction time and utilizing t-EMG throughout retraction, while understanding that the specificity of this monitoring technique is low during initial retraction and increases with longer retraction duration.

Complications in operative Scheuermann kyphosis: do the pitfalls differ from operative adolescent idiopathic scoliosis?
A prospective multicenter database of operative patients with Scheuermann kyphosis (SK) with minimum 1-year follow-up was studied for major complications compared with contemporaneous operative patients with adolescent idiopathic scoliosis (AIS) from the database. ⋯ 2.

Multicenter Study Controlled Clinical Trial
[Structured rehabilitation after lumbar spine surgery : subacute treatment phase].
There are currently no uniform standards regarding rehabilitation of patients after lumbar spine surgery. Due to significant improvements in surgical methods in recent years, an increase in postoperative training intensity is now possible. Conservative rehabilitation has yet to adapt to this reality. Earlier initiation of structured rehabilitation after the acute phase is often regarded with skepticism. ⋯ A structured postoperative rehabilitation program results in significant improvements in the parameters of pain and quality of life, and does not increase the risk of postoperative complications.

Prospective multicenter assessment of risk factors for rod fracture following surgery for adult spinal deformity.
Improved understanding of rod fracture (RF) following adult spinal deformity (ASD) surgery could prove valuable for surgical planning, patient counseling, and implant design. The objective of this study was to prospectively assess the rates of and risk factors for RF following surgery for ASD. ⋯ Rod fracture occurred in 9.0% of ASD patients and in 22.0% of PSO patients with a minimum of 1-year follow-up. With further follow-up these rates would likely be even higher. There was a substantial range in the rate of RF with PSO across centers, suggesting potential variations in technique that warrant future investigation. Due to higher rates of RF with PSO, alternative instrumentation strategies should be considered for these cases.
