Laminectomy is an effective procedure for relieving pressure on spinal nerves, but during the procedure, many spinal stabilizing structures are destroyed even though they are not directly compressing the nerves (lamina, spinous process, interspinous ligament, supraspinous ligament). The reason for that is that these structures are "in the way," that is they block the surgeon's access to the spinal canal. In some patients, excessive spinal destabilization and muscle damage from laminectomy results in "postlaminectomy syndrome."
Laminectomy, a procedure that relieves pressure on spinal nerves, often leads to the destruction of surrounding stabilizing structures like the lamina, spinous process, interspinous ligament, and supraspinous ligament. This is because these structures obstruct the surgeon's access to the spinal canal. In some patients, this can lead to postlaminectomy syndrome due to excessive instability and muscle damage.
