Yksityiskohtainen kuvaus
PRIMARY OBJECTIVE:
I. To evaluate the feasibility of acquiring analyzable sacral reflex neuromonitoring data at baseline and case closure during surgery.
SECONDARY OBJECTIVES:
I. To characterize sacral reflex parameters amplitude, latency, waveform morphology, and Nerveana Power Index (NPI) at baseline under standardized intraoperative neuromonitoring conditions in patients undergoing spinal procedures without sacral nerve root involvement and patients undergoing sacrectomy.
II. To describe intraoperative changes in sacral reflex parameters from baseline to end-of-case during standardized intraoperative neuromonitoring in patients undergoing sacrectomy.
III. To characterize the relative contribution of individual sacral nerve roots to sacral reflex responses during intraoperative stimulation in patients undergoing sacrectomy.
IV. To characterize longitudinal changes in postoperative functional outcomes in patients undergoing sacrectomy.
EXPLORATORY OBJECTIVES:
I. To explore the association between intraoperative sacral reflex changes and postoperative functional outcomes in patients undergoing sacrectomy.
II. To explore the association between sacrifice of higher- versus lower-contributing sacral nerve roots and postoperative functional outcomes in patients undergoing sacrectomy.
OUTLINE:
Patients undergo neuromonitoring of the sacral reflexes at predefined time points during standard of care surgery.
After completion of study treatment, patients are followed up at 21 days, 6 weeks and 3, 6 and 12 months.

Mitä tutkimuksessa mitataan?
Ensisijaiset tulostoimenpiteet
Tulosmittaus |
Toimenpiteen kuvaus |
Aikaikkuna |
|---|---|---|
|
Reproducible and interpretable bulbocavernosus reflex (BCR) and external urethral sphincter (EUS) reflex responses (feasibility)
Aikaikkuna: From baseline, Up to 1 year
|
Reproducible is defined as the ability to elicit a reflex response on repeated stimulation with consistent waveform presence and morphology at a given timepoint.
Interpretable is defined as a recorded reflex response that is distinguishable from background noise and artifact and permits determination of response presence or absence and measurement of latency and amplitude.
A two-sided 95% Clopper-Pearson confidence interval will be provided as a measure of precision.

From baseline, Up to 1 year

Distribution of BCR reflex parameters
Aikaikkuna: From baseline, Up to 1 year
|
Amplitude, latency, frequency distribution, etc, measured via intraoperative neuromonitoring (IONM).
), Analyses will first be conducted separately within thoracolumber and sacrectomy patient groups.
Descriptive statistics will be reported for BCR for each group.
Next, to compare the mean values between the two groups, t-test or Mann-Whitney U-test will be implemented depending on the distribution of these parameters.
Additionally, within the sacrectomy group, the changes of these parameters from baseline to the end-of-case will be assessed either through paired t-test or Wilcoxon's signed rank test, depending on the distribution of each parameter.
