Diagnosis

Recurrent lumbar disc herniation at L5-S1, illustrated in Figure 3 of Choi et al. (2016).

Procedure and level

Revision biportal endoscopic discectomy. L5-S1: one treated motion segment.

Surgical levels and level count

Treated levels: 1 level; L5-S1
Decompression: 1 level; L5-S1
New fusion: None described

Figure 3 identifies one recurrent disc level, L5-S1. This is a publication-derived case; individual operator attribution is not established.

One level means one treated motion segment, such as L4-L5. Decompression and fusion can overlap; their counts are not added. Counts follow the source description and have not been re-audited against private charts.

Clinical presentation

The published example documents recurrence seven months after open microdiscectomy.

Neurologic findings

Not reported in the available source.

Prior nonoperative treatment

Not reported in the available source.

Imaging and clinical concordance

Figure 3 follows initial herniation, postoperative imaging, recurrence, and imaging after revision.

Reasoning recorded for the procedure

The report discusses reaching recurrent disc material through a scarred field while limiting additional facet removal.

Operative considerations

The technical report describes identifying bone before releasing adhesions and removing the recurrent fragment.

Postoperative course

Individual long-term functional outcomes are not supplied for the illustrated case.

Postoperative imaging

The figure describes decompression and preservation of the facet after revision. Imaging does not establish symptom recovery.

Educational point

Compare the anatomical target before and after revision. This single published example cannot establish comparative safety or effectiveness.

Published images and video

Media are identified by their public source. Journal figures open at the original source; operative video illustrates a technical example. Imaging and operative appearances do not measure pain relief, function, or durable fusion.

Source, authorship, and limitations

Source material: Choi et al., Clinics in Orthopedic Surgery (2016), Figure 3. An educational synopsis of the published Figure 3 case. Han-Jin Jang is a coauthor; the publication does not establish that he personally performed this patient's procedure. Publication consent and clinical review are governed by the source journal. The original figure remains on the publisher/PMC page. This entry was organized on 2026-09-11; this date records a website update, not a new clinical review.

Selection is educational. No population denominator, consecutive recruitment process, comparative group, or complete follow-up dataset is supplied. A missing complication field does not mean that no complication occurred. Published observations do not predict another patient's outcome.

No new private patient files were added in this update. Corrections and future clinical additions follow the editorial policy.
