Collection reorganized 2026-09-11 · 9 educational entries · Physician-facing education
Nine source-labelled entries: seven clinical summaries, one operative-video example, and one case from a paper coauthored by Han-Jin Jang. Counts describe educational material. They do not measure unique patients, surgical volume, or outcome rates.
Unreported fields stay unreported. A postoperative image is not a functional outcome, and a website update is not a new clinical review. Read the publication policy.
A level is one treated motion segment, such as L4-L5. Decompression and fusion at the same segment count once. The new operative target and a longer pre-existing fusion construct are reported separately. Two entries do not identify their exact operated levels.
