Cervical lift-up laminoplasty with titanium basket plates after resection of intradural tumor

Abstract

Background: Performing cervical laminoplasty after wide laminectomy may be technically demanding. The unique technique of cervical lift-up laminoplasty using titanium basket plates was applied for the reconstruction of cervical laminae after wide laminectomy for the resection of intradural tumors. Materials and Methods: This technical study included 14 cases that could be followed periodically for at least 6 months after surgery. Participants were 8 male and 6 female, with a mean age of 41.6 years (range, 13–71 years). Tumors were intramedullary in 11 cases and extramedullary in 3 cases. After resection of intradural tumors, custom-designed titanium baskets were fitted to expand the spinal canal. Combining baskets of different sizes are also possible for each side at one level. A mixture of hydroxyapatite granules and collagen was packed into the basket. The reconstructed posterior laminae were secured using titanium mini plates. The fascia of the paravertebral muscles was sutured to the spino-ligamentous complex to further stabilize the posterior elements of the cervical spine. Results: No wounds or implant problems requiring revision surgery were recognized. Imaging analysis demonstrated no significant change in C2–C7 angle cervical range of motion between before and after surgery, suggesting sequential spinal stability at the base of the laminae. Conclusions: This technical note suggests that cervical lift-up laminoplasty with titanium basket plates appears practical and useful as a procedure to reconstruct cervical laminae after wide laminectomy.
