Study Design. En bloc resection of a chordoma of the C5 vertebra with
wide surgical margins.
Objective. To present the surgical technique of total spondylectomy for
a chordoma of the C5 vertebral body.
Summary of Background Data. Malignant bone tumors require wide
resection. Wide resection by total en bloc spondylectomy is difficult or
not feasible for malignant vertebral tumors of the cervical spine due to
the peculiar anatomic complexity of this region, including the vertebral
arteries and the neural structures. There are no previous reports of en
bloc resection of cervical spine tumors with wide surgical margins.
Methods. Using staged posterior and anterior approaches, a total en bloc
spondylectomy and spine arthrodesis was performed. En bloc excision of a
C5 chordoma was achieved using a threadwire T-saw (Tomita and Kawahara,
Kanazawa, Japan) with surgical margins free of tumor. The patient
received postoperative adjuvant proton beam radiation therapy.
Results. The patient remains disease-free 9 years after the operation.
Conclusion. Total en bloc spondylectomy with wide surgical margins is
feasible for malignant bone tumors of the cervical spine.
