The patient attended the authors\u2019 institution with loss of muscle strength and sensitivity impairment in both legs, gait instability, bowel constipation, urinary incontinence, and weight loss. Preoperative magnetic resonance imaging and positron emission tomography\/computed tomography showed intrapelvic and posterior extension of the tumor but sparing of S1 and the sacroiliac and lumbosacral joints. After a multidisciplinary discussion of the case, a staged anterior\u2013posterior approach to the sacrum was chosen. The abdominal approach allowed full mobilization of the uterus, ovaries, bladder, and colon and protection of iliac vessels. After tumor resection, a synthetic surgical mesh was placed over the sacrum to minimize soft tissue defects. Then, the posterior stage allowed the authors to perform a bicortical osteotomy, achieving wide tumor excision with minimal nerve root injury. Spinopelvic fixation was not necessary, because both sacroiliac and lumbosacral joints remained intact. A few days after the surgery, the patient restarted ambulation and recovered sphincter control.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>Multidisciplinary planning and a staged abdominal and posterior approach for partial sacrectomy were fundamental to preserve neurological function in this case.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case21384","type":"journal-article","created":{"date-parts":[[2021,9,27]],"date-time":"2021-09-27T03:28:15Z","timestamp":1632713295000},"source":"Crossref","is-referenced-by-count":1,"title":["Nerve preservation during partial sacrectomy by two-stage anterior and posterior approach: illustrative case"],"prefix":"10.3171","volume":"2","author":[{"given":"Parm\u00e9nides","family":"Guadarrama-Ort\u00edz","sequence":"first","affiliation":[{"name":"Department of Neurosurgery"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ingrid","family":"Montes de Oca-Vargas","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery"},{"name":"Programa de Servicio Social en Investigaci\u00f3n, and"},{"name":"Internado M\u00e9dico de Pregrado, Centro Especializado en Neurocirug\u00eda y Neurociencias M\u00e9xico (CENNM), Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Alberto","family":"Chore\u00f1o-Parra","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andr\u00e9","family":"Garibay-Graci\u00e1n","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery"},{"name":"Programa de Servicio Social en Investigaci\u00f3n, and"},{"name":"Facultad de Estudios Superiores (FES) Iztacala, Universidad Nacional Aut\u00f3noma de M\u00e9xico, Tlalnepantla de Baz, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deyanira","family":"Capi-Casillas","sequence":"additional","affiliation":[{"name":"Facultad de Estudios Superiores (FES) Iztacala, Universidad Nacional Aut\u00f3noma de M\u00e9xico, Tlalnepantla de Baz, Mexico"},{"name":"Escuela Nacional de Medicina y Homeopat\u00eda, Instituto Polit\u00e9cnico Nacional, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alondra","family":"Rom\u00e1n-Villagomez","sequence":"additional","affiliation":[{"name":"Facultad de Estudios Superiores (FES) Iztacala, Universidad Nacional Aut\u00f3noma de M\u00e9xico, Tlalnepantla de Baz, Mexico"},{"name":"Escuela Nacional de Medicina y Homeopat\u00eda, Instituto Polit\u00e9cnico Nacional, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Citlaltepetl","family":"Salinas-Lara","sequence":"additional","affiliation":[{"name":"Departamento de Neuropatolog\u00eda, Instituto Nacional de Neurolog\u00eda y Neurocirug\u00eda \u201cManuel Velasco Su\u00e1rez\u201d, Mexico City, Mexico; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulises","family":"Palacios-Z\u00fa\u00f1iga","sequence":"additional","affiliation":[{"name":"Servicio de Neurocirug\u00eda, M\u00f3dulo de Columna, Hospital Regional 1\u00b0 de Octubre, Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE), Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c1ngel Daniel","family":"Prieto-Rivera","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Surgery of the Pelvic and Sacral Tumor","doi-asserted-by":"publisher","first-page":"165","DOI":"10.1007\/978-94-024-1945-0_21","article-title":"Surgical anatomy of the sacrum","author":"Qu H","year":"2020","unstructured":"Qu H, Guo W.
