Sacral Mass Resection

Abstract Background: Sacral tumours are rare tumours that affect sacrum and can cause back pain and neurological disorders, bony erosion different pathologies can occur like chordoma, metastasis, giant cell tumour, neurofibroma and schowano-ma, surgical excision with or without fixation is the ideal managment. Aim of Study: The aim of this study is to record the ra-diological and clinical results of sacral masses that have been post-located. Patients and Methods: Between January 2020 and January 2023, ten patients with post-located sacral masses underwent surgical resection using a post approach, with or without spin-opelvic fixation using a modified Galveston technique if more than 50% of the sacroiliac joints were involved. The pathology showed giant cell tumors in two cases, aneurysmal bone cysts in three cases, chordomas in three cases, and neurofibromas in two cases; gross total resection was performed in eight cases, and the patients’ low back and leg pains recovered well in eight of the cases, while the two cases that required fixation remained for approximately five months before fusion occurred, with the exception of four cases in which sphincteric disturbance recov-ered after three months. Conclusion: In conclusion, spinopelvic reconstruction and partial or complete sacrectomy are necessary for the surgical management of sacral malignancies. Due to the fact that most spine surgeons are not experienced with the technique needed for these procedures, these lesions provide a significant surgical obstacle.
