Total en bloc spondylectomy is a useful technique in treating primary and secondary spinal malignancies, but requires extensive instrumentation to achieve difficult fusions, and requires extensive exposure of neurovascular structures that poses additional risk of nerve root and vascular injury. More limited resections may reduce these risks, especially in the cervical or lumbosacral spine. We report a technique used in two patients with lateralized primary vertebral tumors of the cervical or lumbosacral spine where tumor removal was achieved through a partial spondylectomy. The advantages of a partial spondylectomy included: (i) avoidance of injuring contralateral neurovascular structures during exposure; and (ii) supplementation of instrumentation by additional fixation at the level of spondylectomy. Partial spondylectomy can be an alternative to total en bloc spondylectomy in properly selected patients with lateralized encapsulated malignant spinal tumors and may be performed in the cervical or lumbosacral spinal regions.

The spine is a common site for metastatic tumors, with 5%-10% of patients developing epidural spinal cord compression (ESCC), which significantly reduces their quality of life and accelerates the process of death. When total en-bloc spondylectomy (TES) radical surgery does not achieve the desired tumor control, palliative care remains the primary treatment option. Traditional laminar decompression or partial tumor resection can only relieve local compression.

Introduction: Bone sarcoma or direct pelvic carcinoma invasion of the sacrum represent indications for partial or total sacrectomy. The aim was to describe the oncosurgical management and complication profile and to analyze our own outcome results following sacrectomy.
Methods: In a retrospective analysis, 27 patients (n = 8/10/9 sarcoma/chordoma/locally recurrent rectal cancer (LRRC)) were included.

Introduction: High-grade spondylolisthesis is defined as cases with more than 50% displacement and spondylolisthesis with Meyerding grade III and higher. The surgical management of high-grade spondylolisthesis is highly controversial. Many surgical methods have been reported such as posterior in situ fusion, instrumented posterior fusion with or without reduction, combined anterior and posterior procedures, spondylectomy with reduction of L4 to the sacrum (for spondyloptosis), and posterior interbody fusion with trans-sacral fixation.

Background: The influence of total en bloc spondylectomy (TES) on spinal stability is substantial, necessitating strong fixation to restore spinal stability. The transverse connector (TC) serves as a posterior spinal instrumentation that connects the left and right sides of the pedicle screw-rod system. Several studies have highlighted the potential of a TC in enhancing the stability of the fixed segments.
