A 45-year-old woman had a grade II chondrosarcoma (T2N0M0G2) located at the spinous processes and laminas of T3-6 with the tumor extension into the spinal canal at T3-4. To perform en bloc tumor resection, we released or disarticulated bilateral costovertebral ligaments from T3-6 and cut the bilateral pedicles at T3-5 all from posteriorly. Then, we completed en bloc resection without violating the tumor capsule.
Our novel procedure, bilateral osteotomy of pedicles for en bloc resection successfully allowed for en bloc tumor resection involving the posterior elements with wide surgical margins.
一位 45 岁女性患有 T3-6 棘突和椎板的 II 级软骨肉瘤（T2N0M0G2），肿瘤延伸至 T3-4 的椎管内。为了进行整块肿瘤切除，我们从 T3-6 处释放或断开双侧肋横突韧带，并从后方在 T3-5 处切断双侧椎弓根。然后，我们成功地完成了整块肿瘤切除，没有侵犯肿瘤包膜。
我们的新方法，双侧椎弓根截骨整块切除术成功地进行了整块切除，包括广泛的手术边缘的后外侧肿瘤。
