En bloc resection, with adequate surgical margins, of primary malignant bone tumors of the sacrum is associated with long term disease control and potential cure. Resection of sacral tumors is difficult due to the proximity of neurovascular and visceral structures, and complete, or even partial, sacrectomy often results in functional loss for the patient.
We describe the technique for en bloc resection of a sacral chordoma through a mid-sacral amputation.
We demonstrate successful removal of a large sacral tumor with wide surgical margins while preserving neurologic function.
This technique for midsacral amputation to remove a sacral tumor en bloc minimizes local recurrence and maximizes neurovascular function.
对于原发性骶骨恶性骨肿瘤，通过广泛的外科边界进行整块切除，可实现长期疾病控制和潜在治愈。由于骶骨肿瘤靠近神经血管和内脏结构，因此切除骶骨肿瘤较为困难，即使进行完整的或部分的骶骨切除术，也常导致患者功能丧失。
我们通过中骶骨截断术来描述整块切除骶骨脊索瘤的技术。
我们成功地切除了一个大的骶骨肿瘤，同时保留了神经功能，获得了广泛的手术边界。
通过中骶骨截断术整块切除骶骨肿瘤的技术可最大程度地减少局部复发，最大限度地保留神经血管功能。
