Laminoplasty is a surgical procedure that has been developed as an alternative to cervical laminectomy, which is used to treat cervical myelopathy. Laminoplasty reconstructs the vertebral lamina to decompress the spinal cord. The term laminoplasty means, "to create a hinge to lift the lamina." [1]
Surgical management options include extensive cervical laminectomy with or without an additional posterior arthrodesis, anterior decompression and arthrodesis, and posterior cervical laminoplasty. [3]
A laminotomy is an orthopaedic neurosurgical procedure that removes part of the lamina of a vertebral arch in order to relieve pressure in the vertebral canal. [1] A laminotomy is less invasive than conventional vertebral column surgery techniques, such as laminectomy because it leaves more ligaments and muscles attached to the spinous process intact and it requires removing less bone from the ...
If the cervical spine is in a fixed kyphotic position and with one to two involved spinal segments, posterior approaches such as laminoplasty (removal of lamina with a bone graft or metal plate as replacement) or laminectomy (removal of lamina without any replacement) with or without fusion can be used for decompression. The posterior approach ...
The posterior longitudinal ligament contains a higher density of nociceptors than many ligaments, so can cause back pain. [1] It may ossify, particularly around cervical vertebrae. [1] The posterior longitudinal ligament has a high density of vasomotor fibres, allowing for increased blood flow to respond to damage to the ligament. [1]
A laminectomy is also the name of a spinal operation that conventionally includes the removal of one or both lamina, as well as other posterior supporting structures of the vertebral column, including ligaments and additional bone. The actual bone removal may be carried out with a variety of surgical tools, including drills, rongeurs and lasers.
Laminectomy is an open or minimally invasive surgical procedure in which a portion of the posterior arch of the vertebrae and/or spinal ligaments is removed from the spine to alleviate the pressure on the spinal canal contents. This procedure is usually performed when decompression of more than one nerve root is needed.
Selective dorsal rhizotomy (SDR), less often referred to as selective posterior rhizotomy (SPR), is the most widely used form of rhizotomy, and is today a primary treatment for spastic diplegia, best done in the youngest years before bone and joint deformities from the pull of spasticity take place. Still, it can be performed safely and ...
