Clinical application of the modified replantation of pedicle spinous process and lamina complex in resection of benign tumors in the thoracic and lumbar spinal canal

Objective To explore the clinical value of modified replantation of pedicle spinous process and lamina complex in the treatment of benign tumor in spinal canal.Medthods From September 2018 to October 2019,18 patients with benign tumors in spi?nal canal were treated in this operation method.While one side supraspinal and interspinal ligaments were reserved as pedicles,the spinous process and lamina complex were removed by piezosurgery.After intraspinal tumors were resected,the spinous process and lamina complex with one side supraspinal and interspinal preserved as pedicle was replanted in situ.The patients were followed for neurologic recovery and imaging changes.Results The patients were followed up for 6 to 18 months(mean 13 months).There was no residual tumor or recurrence in situ according to postoperative X-rays,CT and MRI.All lamina replanted in situ kept in place during the followd-up period.It took 4.5 months(mean)for lamina of vertebra to acquire bone fusion.No vertibral instability or spinal stenosis was observed.Conclusion Modified replantation of pedicle spinous process and lamina complex during resection of benign spinal canal tumoris beneficial for reconstructing anantomical structure of spine,maintaining the postoperative spinal stability and decreasing complications.
