Correction of Postlaminectomy Cervical Kyphosis in an Operated Case of Cervical Spine Primitive Neuroectodermal Tumor.

A 14-year-old boy presented with gradually worsening spastic quadriparesis and cervical kyphotic deformity as a consequence of laminectomy for tumor debulking and chemoradiotherapy done 2 years prior for cervical primitive neuroectodermal tumor. Problems to be addressed particularly to the case were a rigid kyphosis of 102.7°, poor soft-tissue coverage, internal gibbus compressing cord, perched facets, and superficial location of cord. The surgery was staged, in that the first anterior release was done with gradually increasing traction to correct the kyphosis progressively. Posterior instrumentation was done in the second stage. Finally, anterior reconstruction with tricortical iliac bone grafting was done. The patient regained full power with complete union at the end of 18 months. Irradiation of tumor along with laminectomy results in loss of posterior tension band which results in progressive kyphotic deformity in children. A staged plan of surgical interventions can help in postoperative correction of deformity with circumferential union and prevention of recurrence. This article describes successful treatment of a patient with postlaminectomy cervical kyphosis with 77° of correction achieved postoperatively and also highlights the importance of anterior and posterior reconstructions to achieve a stable vertebral column.
