Meet Dr. Marc Greenberg
A fellowship-trained spine surgeon in Fort Wayne
Dr. Marc Greenberg is a fellowship-trained spine surgeon with Orthopaedics Northeast in Fort Wayne whose practice focuses on minimally invasive spine surgery, motion-preserving options, and robotic-assisted procedures when appropriate. Dr. Greenberg earned his medical degree at Mayo Clinic, completed orthopedic surgery residency at Johns Hopkins, and completed spine surgery fellowship training at Brown University.
When surgery is the right choice, the goal is the smallest effective approach and the least unnecessary tissue disruption. For conditions that improve without surgery, the same evidence-based rigor guides every non-surgical recommendation.

Making Sense of Spine Surgery
An evidence-based overview covering what to expect — from diagnosis and treatment options through recovery.
Our Approach
Recommendations are based on the diagnosis, examination, imaging, prior treatment, health factors, and patient goals.
- Non-Surgical FirstMost conditions begin with nonsurgical care. Surgery is considered when the diagnosis, symptoms, objective findings, imaging, prior treatment, and goals support it; urgent neurologic findings can change the timing.
- Evidence-Based DecisionsRecommendations draw on peer-reviewed evidence, the clinical examination, the actual imaging, prior treatment, function, health factors, and the patient’s goals.
- Clear CommunicationThe discussion should connect the diagnosis, imaging, reasonable options, uncertainty, and patient-specific recovery milestones in plain language.
- Referral CoordinationRecords and care plans can move through the secure clinical channels designated by the office when coordination is needed.
- Second OpinionsIf another surgeon told you surgery is your only option, get a second look. Dr. Greenberg reviews your imaging and evaluates whether minimally invasive or non-surgical approaches may be appropriate.
- Motion-Preserving OptionsWhen surgery is needed, fusion is not always the answer. Cervical disc replacement is designed to preserve motion, and selected disc herniations may be treated without fusion. Fusion is used when the anatomy and surgical objective require it.

How quickly can I get an appointment?
Appointments begin August 31, 2026. You can request an appointment now, and the office will contact you about availability and next steps.
Do I need a referral to see Dr. Greenberg?
Referral requirements vary by insurance plan and circumstance. Contact the office and your health plan to confirm what is required before the visit.
What makes minimally invasive spine surgery different?
Minimally invasive techniques use smaller working corridors, specialized instruments, and advanced imaging to reach the spine while limiting unnecessary tissue disruption. The appropriate approach depends on the diagnosis, anatomy, and surgical goal.
How do I know if I need spine surgery?
Most spine conditions do not require surgery. It is considered when symptoms, examination, and imaging identify a structural problem that is likely to improve with an operation, or when progressive neurologic findings change the balance of options. The evaluation should also explain when surgery is unlikely to help.
What insurance do you accept?
Insurance participation and coverage vary by plan and service. Confirm benefits and network status directly with your health plan. The office can explain its own scheduling and billing requirements, but website information is not confirmation of coverage or payment.
