Abstract:
We discuss the technical details and operative advantages of approaching pathologies from the contralateral side in cases of asymmetric spinal stenosis. The contralateral approach offers better manipulative freedom and a more accessible target approach along the plane of the pathology, allowing safer decompression and facet preservation; further, this approach is ergonomic for surgeons. We recommend the adoption of this approach in decompressing asymmetric spinal stenosis.
