Diagrammatic representation of spinaplasty operation. (a) Line diagram of spine in sagittal view shows normal attachment of supraspinous and interspinous ligaments. (b) Supraspinous and interspinous ligaments are cut at most distal level of the planned decompression. Spinous processes are cut from the base and lifted up as a continuous median mass still attached to the suraspinous and interspinous ligament and their undisturbed proximal attachment. (c) After adequate decompression and suturing of the deepest layer of muscles over the dura, the median structures are sutured to the distal bed and paraspinal muscles (d) line diagram of axial view and (e) axial view of CT scan shows laminectomy and remains of spinous process after spinaplasty
