Lumbar disc herniation (LDH) often results in back pain and radicular pain and is frequently treated with minimally invasive non-surgical methods in Korean Armed Forces Hospitals. Automated percutaneous lumbar discectomy (APLD) has been reported to have good clinical outcomes with low complication rates; however, the clinical efficacy of APLD performed in young male soldiers is uncertain. In order to clarify the efficacy of APLD for the treatment of LDH in young male soldiers, we designed a retrospective case–control study to compare patients who received APLD with patients treated with epidural steroid injection (ESI) alone. A total of 181 patients were enrolled and divided into the APLD (n = 92) and ESI (n = 89) groups according to the treatment modality. A simple logistic regression analysis was conducted to clarify the difference between the two. To optimize patient selection, APLD group was additionally divided for subgroup analysis into favorable (n = 59) and unfavorable (n = 33) groups based on satisfaction scales. A simple logistic analysis was also performed. The differences between pre- and postoperative numerical rating scale of pain (P = .0027) and hospital-own satisfaction scale (P = .0045) of the APLD group were significantly better compared to those of the ESI group. In terms of subgroup analysis, single-level pathology (P = 0.244) and protruded disc (P = .0443) were associated with favorable outcomes, whereas dual pathology and extruded disc were related with unfavorable outcomes. APLD using Dekompressor, performed in young male soldiers with back and radicular pain owing to LDH, showed better clinical outcomes compared to the ESI only therapy. Additionally, a single-level pathology with protruded disc was associated with favorable outcomes and may be indicated for treatment.
