Abstract
BACKGROUND: Lumbar burst fractures (complete or incomplete) of L5 have a low incidence, accounting for 1.2% of all spinal burst fractures. Treatment for these fractures remains controversial. Decompression of neural elements and stabilization of the spine to preserve lordosis and avoid kyphotic deformity are recommended when a patient has a neurological deficit and an unstable fracture. Otherwise, the fracture could be managed conservatively. METHODS: We report a detailed step-by-step unilateral biportal endoscopy technique used in a patient with an L5 incomplete burst fracture and neurological deficit. RESULTS: The patient had an acceptable immediate postoperative course; lower back pain and radicular symptoms improved significantly after surgery. CONCLUSIONS: Our unilateral biportal endoscopy technique for L5 incomplete burst fractures offers the capability to perform enough decompression of neural elements and assist other procedure-related maneuvers under direct endoscopic visualization. This technique could be considered another minimally invasive spine surgery option for treating selected patients with L5 incomplete burst fractures.
