Abstract

<p>Introduction: Lumbar disc herniation (LDH) is a common disease in daily clinical practice. However, there are conflicting reports on the effectiveness of early surgery for drop foot due to LDH, a typical symptom of radiculopathy, and no consensus has been reached. The purpose of this study was to investigate the effectiveness of early surgery within 7 days for drop foot due to LDH.</p><p>Methods: Patients who underwent surgical decompression for drop foot (tibialis anterior [TA] Medical Research Council grade ≤2) due to LDH from September 1, 2017 to November 31, 2021 were categorized into the early surgery group (within 7 days, 15 patients) and the late surgery group (after 8 days, 16 patients), and the postoperative TA MRC grades were compared between the two groups.</p><p>Results: Six months after surgery, 11 patients (73.3%) in the early surgery group and 10 patients (62.5%) in the late surgery group had TA MRC grade ≥3 (P=0.704). One year after surgery, 12 patients (80.0%) and 12 patients (75.0%) in each group had TA MRC grade ≥3 (P>0.999). The mean TA MRC grade improvements 6 months after surgery were 2.07 in the early surgery group and 1.56 in the late surgery group (P=0.317). Improvements 1 year after surgery were 2.47 and 1.88 in the two groups, respectively (P=0.107). There was no significant difference between the two groups in either analysis.</p><p>Conclusions: This study did not demonstrate the effectiveness of early surgery within 7 days for drop foot due to LDH.</p>
