89% of patients achieved excellent or good outcomes.

Mean follow-up was 8 months; average patient age was 38 years.

Low complication rate: 4.5% required open surgery, 6% experienced temporary dysesthesia; no major neurovascular injuries or deaths.

Conclusions:

TPELD is a minimally invasive, safe, and effective treatment for soft contained or noncontained contiguous LDH.
Successful outcomes were achieved in a high percentage of patients.
The procedure demonstrated a favorable safety profile in experienced hands.
