A study with sites in several countries is counted once per country, taken from the location block of each registry record.

What the map means for Back Pain & Disc Degeneration

Spine injection studies follow orthopaedic and interventional-radiology capacity, and the commercial market follows the same specialties. Because image-guided injection is easy to deliver almost anywhere, this is a field where a country's presence in the trial map says little about the quality of what is sold locally.

What travelling for a trial actually involves

If a site is abroad, the practical questions are who provides follow-up at home, what happens if an adverse event occurs after you fly back, and whether the protocol permits remote assessment at all. Most do not.

Multi-country studies, named

Registered studies with sites in more than one country — the clearest evidence of collaboration rather than a single-centre series.

Why trial geography is not a shortlist

Where studies happen reflects who funds and who authorises them. Treating that as a ranking of care quality confuses the research system with the treatment market, two things that overlap far less than medical-tourism marketing implies.

Before treating geography as a shortlist, read the legality overview by country and what "best country" actually means here.

When these studies started

Registrations by start year since 2020: 2020 (2), 2021 (2), 2022 (1), 2023 (1), 2024 (1), 2025 (1), 2026 (2). Activity for this condition spans 2007 to 2026, which shows whether interest is growing, flat or past its peak.

Frequently asked

Which countries run stem-cell trials for Back Pain & Disc Degeneration?

Sites are registered in 11 countries; the largest is United States (~50% of country mentions, 2026-08-29).

Does a country with many trials mean better treatment there?

Volume tracks funding and law, not outcomes. The relevant question is what oversight covers the specific clinic and product you are considering.

Are trial sites and commercial clinics the same thing?

Usually not. The hospital running a registered study is often unrelated to clinics marketing treatments to international patients in the same city.
