| Popis: | Introducción: Los tumores del sacro representan Introduction: Tumors of the sacrum represent less than 7% of spinal tumors. Secondary tumors due to multiple myeloma or prostate, breast, lung and colon carcinomas predominate. Chordoma is the most frequent primary malignant tumor and giant cell tumor is the most common benign lesion. For its evolution, involvement of extra bone structures and poor response to the adyuvant therapy, surgery is the most commonly used treatment, the approach and the need for instrumentation depend on tumor to treat. The objectives of this study are to evaluate the use of partial resection of sacrum, analyze the surgical technique and assess complications. Methods: Four patients with diagnosis of sacral tumor below S1, who presented with pain and images confirming the injury. All underwent an en bloc resection by posterior via preserving S1. The technique is described. Results: The pathological results were: a chordoma, a malignant nerve sheath tumor, a chondrosarcoma and a metastasis of prostatic carcinoma. S1 function was preserved in all patients; one has permanent bladder dysfunction. Wound dehiscence, infection and cerebrospinal fluid fistula were detected. Patients are free of disease after a follow-up of 6-24 months. Conclusions: Partial resection of the sacrum using a unique posterior approach may be indicated when the injury involves from S2 distally and no sacroiliac involvement is observed. Root preservation is vital to guarantee the best postoperative results and a lower rate of infection. Facultad de Ciencias Médicas |
