Research & Publications

What This Page Reports

Dr. Marc Greenberg has contributed to peer-reviewed studies, book chapters, presentations, and educational work across spine surgery and orthopedics. The goal of this page is to make those contributions easy to verify and to keep published research distinct from claims about one practice’s results.

Practice-Specific Outcomes

Greenberg Spine does not currently publish audited practice-specific complication rates, readmission rates, return-to-operating-room rates, fusion rates, or patient-reported outcome measures on this website. Numbers reported in published studies describe the populations and methods in those studies; they are not a promise of an individual result.

As the practice develops a sufficiently complete and validated outcomes dataset, any future public report should define the denominator, follow-up period, inclusion criteria, missing-data handling, and source of verification.

Source-Linked Research

Pain Self-Efficacy and Preoperative Opioid Use

Dr. Greenberg coauthored a 2023 Spine Journal study of 578 elective spine-surgery patients. The study found that a PSEQ score below 22 was associated with daily preoperative opioid use and several baseline pain, disability, and PROMIS measures.

Smoking and Cervical Disc Replacement

This site includes a source-linked summary of Dr. Greenberg’s peer-reviewed work examining smoking and reoperation risk after cervical disc replacement.

Minimally Invasive Fixation

A separate source-linked article summarizes Dr. Greenberg’s coauthored work on minimally invasive fixation and distinguishes the study findings from claims about any one patient or practice.

How Evidence Is Used

Published evidence helps frame expected benefits, tradeoffs, and uncertainty. It does not replace the individual diagnosis. A treatment recommendation still depends on symptoms, examination, actual imaging, prior treatment, health factors, function, and goals.

Technology claims are handled the same way. Endoscopy, navigation, and robotics can change the working corridor, visualization, planning, or implant guidance. They do not independently determine whether surgery is indicated or guarantee a clinical outcome.

Verify Credentials and Publications

The professional citations page lists third-party profiles and credential-verification resources. The research library organizes source-specific summaries and publications.
