Impact of lamina preservation height during posterior decompression on lumbar biomechanical stress distribution: a finite element study
Preserving less than 50% of lamina height during posterior decompression severely compromises spinal stability. To minimize postoperative biomechanical risks based on this model, preserving at least 50% of the lamina height appears advisable. This study provides quantitative, biomechanically-grounded evidence that can serve as a reference for bone preservation in a wide spectrum of posterior spinal decompression procedures.
