Abstract:
Objective To discuss total vertebrectomy and spine stability and reconstruction by pos-terior ap proach for thoracic vertebra tumor and pedicle screw system fixation and intervertebral fusion.Methods Eighteen patients of 3males and15females of thoracic total vertebral tumor were operated in this group.The age of the group were from14to58years old,with the average of 23years.There were4aneurysmal bone cysts,2hemangiomas,2osteoblastomas,1neurilemomas,5giant cell tumor,1solitary myeloma and3metastatic thoracic vertebra tumors.The locations of the tumors was T 4 in1case,T 5 in1case,T 6 in2cases,T 8 in4cases,T 9 in3cases,T 10 in4cases,T 11 in2cases and T 12 in1case respectively.Pre-operative Frankel classification was grade A in6cases,B in7cases,C in3cases and E in2cases.Cir-cumferential decompression was performed with total spondylectomy through one-stage posterior ap proach.Anterior verte bral reconstruction was provided by autograft(ribs or ilium)bone or metallic cage;Posterior reconstruction was achieved by pedi cle screws system of CD or TSRH,Scofix fixation and auto graft fusion.Results The mean follow-up was8months,ranging from3months to24months.Twelve of 16cases with neu ro logical dysfunction were recovered completely,1case recovered from Frankel grade A to C,2cases from grade A to D,1case from grade B to D.The patient with neurilemmoma recurred and became ma lig nant after20months of operation and died4months later.One case of metastatic tumor of lung cancer sur vived6months after opera tion.One patient with giant cell tumor recurred.The other patients were still alive in the latest follow-up.There were no instruments breakage and spinal instability during the follow-up.Conclusion If the thoracic total vertebral tumor compress spinal cord se riously,the patients should be indi cat-ed for surgical treatment constructively.Total vertebrectomy followed by one-stage posterior approach re con-struction could relieve the com pression caused by tumor and reconstruct the stabilization of spine effectively.
