Meyerding's 1938 JAMA paper presents 583 consecutive spondylolisthesis cases from the Mayo Clinic. It asks: how common is this condition, who gets it, and how should the degree of slip be graded? The paper introduced the four-grade classification system still in universal use today.
Before this paper, spondylolisthesis was considered rare and predominantly a female condition linked to pregnancy — so physicians rarely looked for it in male laborers presenting with chronic back pain.
When a male patient in his 30s or 40s presents with years of mechanical low back pain worsened by labor and relieved by recumbency, get a standing lateral lumbar radiograph. This paper established that pattern as the classic presentation, and that the grade can only be determined on the lateral view.
Remember that more than 10% of patients with confirmed spondylolisthesis are asymptomatic. A slip on imaging does not automatically explain a patient's pain. Correlate carefully before attributing symptoms to the finding.
The Meyerding grading system this paper introduced remains the universal language for describing slip severity and directly informs modern treatment thresholds. High-grade slips (Grades 3 and 4). Representing only about 10% of cases. Carry the greatest deformity burden and are the focus of all subsequent surgical classification work, including Marchetti-Bartolozzi and the Spinal Deformity Study Group criteria.
