SLIP II Registry: Spinal Laminectomy Versus Instrumented Pedicle Screw Fusion
NCT03570801 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of the project is to perform an RCT comparing patient satisfaction and outcome with or without the use of an expert panel. The purpose is also to create a registry to compare the effectiveness of decompression alone versus decompression with fusion for patients with degenerative grade I spondylolisthesis and symptomatic lumbar spinal stenosis. Primary analysis will focus on the patients' improvement from baseline patient-reported outcome questionnaires. In addition, the SLIP II registry aims to (i) develop an algorithm which could identify cases in which surgical experts are likely to recommend one treatment (i.e. \>80% of experts recommend one form of treatment) and (ii) develop a radiology-based machine learning algorithm that would prospectively classify patients as either 'stable' or 'unstable.' In addition to patient reported outcomes, step counts will be collected in order to determine the correlation of step count with patient-reported outcomes (ODI and EQ-5D) and the need for re-operation. This registry portion of the study aims to prospectively collect comparative data for these patients treated with either decompression alone or decompression with fusion.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03570801
The ClinicalTrials.gov registry entry for NCT03570801 describes a study currently listed as active not recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 662 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Lahey Clinic, which has 17 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 4 conditions, with Lumbar Spinal Stenosis appearing as the primary indexed condition, and to 1 intervention — of which Expert Panel Review is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03570801 reports 17 study locations spanning 14 distinct geographic areas — top geographies include Massachusetts, Minnesota, New York. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
