This study aimed to evaluate the oncologic and functional outcome of the cases treated with hemisacrectomy through a sagittal plane in the sacrum and simultaneous en bloc resection together with the ipsilateral sacroiliac joint without sacrificing the contralateral sacral nerves and summarize tumor resection techniques and reconstruction strategy. ⋯ This procedure has an oncologic outcome that is similar to that of other high sacrectomy and a much better function outcome. Although demanding, it is indicated in selected patients.

We measured the length, width, height, and angles related to both Meyerding grading system and Marchetti-Bartolozzi classification in L5-S1 spondylolytic spondylolisthesis patients to investigate the anatomical characteristics of fifth lumbar pedicles. ⋯ In L5-S1 spondylolytic spondylolisthesis, a longer screw is suitable for insertion of L5 pedicle and the screw should be inserted more medially compared to patients without spondylolysis.
