title: Microsurgical infrapedicular paramedian approach for retrovertebral lumbar disc herniations. Technical note.
abstract: The author performed a microsurgical infrapedicular paramedian approach in 35 patients (23 men and 12 women) to remove herniated lumbar retrovertebral discs that did not have an apparent origin at either the superior or inferior disc level. The goal of this surgery was to minimize the bone resection, preserve the facet joint, and avoid the risk of secondary vertebral instability. The Macnab outcome classification was used to assess all patients who attended follow-up examination for at least 15 months. The clinical results were excellent or good in 34 (97%) of 35 cases. This minimally invasive lumbar spine technique resulted in minimal morbidity, excellent clinical benefits, and a long-term outcome without evidence of secondary segmental instability.
