Abstract

Background Context

Although lumbar disc herniation (LDH) classically presents with lower extremity radiculopathy, there are patients who have substantial associated back pain.

Purpose

The present study aims to determine if patients with LDH with substantial back pain improve with decompression alone.

Study Design

This is a longitudinal observational cohort study.

Patient Sample

Patients enrolled in the Quality and Outcomes Database with LDH and a baseline back pain score of ≥5 of 10 who underwent single- or two-level lumbar discectomy only.

Outcome Measures

Back and leg pain scores (0–10), Oswestry Disability Index (ODI), and EuroQoL 5D were measured.

Methods

Standard demographic and surgical variables were collected, as well as patient-reported outcomes at baseline and at 3 and 12 months postoperatively.

Results

The mean age of the cohort was 49.8 years and 1,195 (52.8%) were male. Mean body mass index was 30.1 kg/m². About half of the patients (1,103, 48.8%) underwent single-level discectomy and the other half (1,159, 51.2%) had two-level discectomy. Average blood loss was 44 cc. Most of the patients (2,217, 98%) were discharged home with routine postoperative care. The average length of stay was 0.53 days. At 3 and 12 months postoperatively, there were statistically significant (p<.000) improvements in back pain (from 7.7 to 2.9 to 3.2), leg pain (from 7.5 to 2.3 to 2.5), and ODI (from 26.2 to 11.6 to 11.2). Patients with a single-level discectomy, compared with patients with a two-level discectomy, had similar improvements in 3- and 12-month back pain, leg pain, and ODI scores.

Conclusions

Patients with LDH who have substantial back pain can be counseled to expect improvement in their back pain scores 12 months after a discectomy.
