Case in brief
A patient with an anterior compartment chondrosarcoma spanning L1-L3 presented with major vascular involvement, specifically the inferior vena cava and left renal vessels. A novel middle column trough technique was employed to safely mobilize the tumor away from these vessels, allowing for en-bloc resection without the need for nephrectomy. Reconstruction was achieved using humeral shaft allograft and instrumentation.
Diagnostic / clinical pearl
The middle column trough technique offers a novel approach for resecting spinal tumors with significant vascular involvement, potentially avoiding more radical procedures like nephrectomy.
