Adult spinal deformity–like sagittal malalignment treated with full endoscopic interspinous cleaning surgery in a patient with Baastrup’s disease: illustrative case
BACKGROUND Baastrup’s disease is a degenerative disorder characterized by contact between adjacent spinous processes and typically presents with extension-related low back pain. Although it is generally regarded as a localized posterior element disorder, its impact on global sagittal alignment remains unclear. OBSERVAT...
